FYI - Being we haven't had any Onan or Wisconsin engines in our shop for repairs, we have no experience with working on them. Apparently, these engines are rare in our area (mid-Missouri). Therefore, we do not offer a custom-made electronic ignition conversion kit for these engines. If someone is willing to bring their Onan or Wisconsin engine to us, we're sure we can fabricate and install an electronic ignition system on it. |

Kill Switch and Conventional (Points and Condenser) Ignition Parts -
  SAFETY FIRST!
Break-Away / Grounding-Type Safety Kill Switch with
Pull-Pin. Use for competition pulling only; mount on rear of tractor.
When the pin pulled, it grounds the ignition coil from producing spark. If
using with a self-energizing magneto or electronic/solid state ignition systems:
Connect one wire to the chassis ground, and connect the other wire to the
points/condenser wire or to the kill terminal on the solid state ignition
coil/module. If using with a battery-powered ignition system: Connect one
wire to the chassis ground, and connect the other wire to the coil negative
(–) terminal. NOTE: With battery-powered ignition, as soon as pin
is pulled (engine will die), manually shut off ignition switch right away
to prevent possible damage to the ignition coil and electronic ignition module
if equipped with crank trigger ignition. This type of switch does not
disable power to the
electric fuel pump on a pulling tractor. It must be
shut-off manually by the ignition switch or an OFF-ON toggle switch.

 Ignition
Points for Kohler, Tecumseh and Clinton engines. Fits Kohler engine models
K90/K91, K141, K161/K160, KV161,
L160/L161, L181,
K181, K241, K301, K321, K330/K331, K341, K361, KT17 (first design), KT17
Series II, KT19 (first design) KT19 Series II, KT21, K482, K532 and K582
with magneto or 12 volt battery ignition (use with mounting bracket). Also
fits Tecumseh cast iron block engine models HH80, HH100, HH120 with magneto
or 12 volt battery ignition (use without mounting bracket); and Clinton engine
models 414, 418, 420, 422 (use without mounting bracket). Also, use this
part when converting from Breakerless Ignition to points and condenser ignition.
IMPORTANT: Sometimes oxidation will form on new points contacts from sitting
in storage, even when sealed in plastic. This happens A LOT with all types
of ignition points. Therefore, do not use sanding material, such as sandpaper
or emery cloth, to clean any electrical contacts! These will leave a gritty
residue between the contacts, causing a faulty connection. Instead, while
the points is installed and the contacts are closed under pressure, use a
[preferably clean]
ignition points file (professional use) or
metal fingernail file (use in a pinch) to remove any
oxidation/debris between the contacts, then drag a piece of [preferably clean]
lint-free paper through the contacts to remove any left-over residue, and
use
brake parts cleaner,
electrical/electronic contact cleaner,
cleaning solvent or
paint thinner (these leave no oily residue) and then use
150± psi compressed air with an
air blow gun nozzle to clean any remaining debris and metal
filings from the contacts. This will guarantee 100% connection with the points.
Also, lubricate the hinge/pivot pin in the points with clean motor oil to
prevent from wearing due to dry friction, which will eventually effect the
ignition timing. Or improve engine performance and longevity with virtually
any engine and eliminate regular maintenance on conventional ignition components
with an Electronic Ignition Conversion
Kit!
  Hex Socket (Allen) Head Cap Screw w/split lock washer and
flat washer. Replaces OEM slotted or aftermarket Phillips head adjustment
screw in points for easier setting of the point gap and/or ignition timing

Ideal for garden tractors with a
longitudinal engine, such as IH Cub Cadet, Economy Power
King, Ford, hydrostatic-drive John Deere, MTD Farm King model 960, Pennsylvania
Panzer, Meteor, Copar, etc. No need to use this Allen head screw for garden
tractors with a
transverse engine, such as older Bolens, belt-drive John
Deere, Massey Ferguson, Sears Suburban, Wheel Horse, etc. NOTE: Threads for
adjustment screw in aftermarket points may need to be rethreaded with a 8-32
UNF TAPER [preferably]
hand tap. And due to risk of stripping threads in the thin metal points
bracket, do not over-tighten this adjustment screw!
   Phillips Head
and Hex Socket (Allen) Head Screws with split lock washers to fasten ignition
points and/or points cover on Kohler engines. Fits Kohler engine models
K90/K91, K141, K161/K160, KV161,

Series II, KT19 (first design) KT19 Series II, KT21, K482, K532 and K582.
These type of screw heads make for easier fastening of points and points
cover to engine block in hard-to-reach places than the OEM slotted head screws
on garden tractors with a
transverse engine as listed above. Each screw replaces
discontinued Kohler part # X-131-1-S.
High Quality Adjustable Chevy (GM) Ignition Points with Stiff Spring for Quick Reaction at open RPM. Use on Kohler K-series K241, K301, K321, K341, K361 competition pulling engines only. NOTE: Not recommended for use on lawn and garden equipment engines due to long exposure to dust and debris, which can contaminate points contacts and cause a misfire. IMPORTANT: Sometimes oxidation will form on new points contacts from sitting in storage, even when sealed in plastic. This happens A LOT with small engine and automotive ignition points. Therefore, while the points are closed under pressure, use a clean steel fingernail file or ignition points file to remove any oxidation/debris between the contacts, then drag a piece of clean lint-free paper through the contacts to remove any left-over residue, and use brake parts cleaner, electrical/electronic contact cleaner, cleaning solvent or paint thinner (these leave no oily residue) and then use 150± psi compressed air with an air blow gun nozzle to clean any remaining debris and/or metal filings from the contacts. This will guarantee 100% connection with the points. Do not use sanding material, such as sandpaper or emery cloth, to clean any electrical contacts! These will leave a gritty residue between the contacts, causing a faulty connection and possible engine misfire. Or improve engine performance and longevity with virtually any engine and eliminate regular maintenance on conventional ignition components with an Electronic Ignition Conversion Kit! $15.00 each, plus shipping & handling. TIP: To prevent small Phillips- or slotted-head screws from falling out of the screwdriver tip when installing in a hard to reach place, first of all, use the correct size screwdriver that fits the screw head, and for ordinary steel screws, temporarily magnetize the screwdriver by rubbing a magnet several times along the length of the shank, or for stainless steel screws, apply a dab of automotive grease in the head of the screw. |

 Ignition Points
Pushrods. NOTE: New OEM Kohler K-series engine models points pushrods
are 1.265" in length, and a used pushrod must be no less than 1.205" in length.
Measure yours accurately with a
dial or
digital caliper to determine if it needs replacing. Or
improve engine performance and longevity with A-1 Miller's custom-made
Electronic Ignition Conversion
Kit!
Ignition Points Pushrods. NOTE: New OEM Kohler points pushrods are 1.550" in length, and a used pushrod must be no less than 1.500" in length. Measure yours accurately with a dial or digital caliper to determine if it needs replacing. Or improve engine performance and longevity with A-1 Miller's custom-made Electronic Ignition Conversion Kit!
NOTE: If the points lobe on the camshaft is severely worn and the ignition timing cannot be fully advanced to the factory setting of 20º BTDC, and completely disassembling the entire engine to install a threaded-on stainless steel nut on the end of the OEM points pushrod (from inside the crankcase; as shown to the right) or to replace the camshaft with one that's in better condition (if one is available) is out of the question, then the alternative is to convert the engine to A-1 Miller's custom-made flywheel-triggered 12 volt electronic ignition.

L160/L161, L181,
K181, K241, K301, K321, K341, K361, K482, K532 and K582. But if the ignition
points pushrod hole is excessively worn, this will effect the ignition timing
as well, and the block will need to be machined for installation of a bronze
sleeve bushing, or the hole can be plugged, and solid state or a custom-made
flywheel- or
crank-trigger electronic ignition system
can be installed. (The translucent silicone rubber diaphragm seal (part
# 220074-S) is no longer available from Kohler.)

  3/16" Steel Plug for Kohler
Ignition Points Pushrod Hole. Fits Kohler engine models K90/K91,
K141, K160/K161, KV161,
L160/L161, L181,
K181, K241, K301, K321, K341, K361, and K482, K532, K582 (with an unworn
points pushrod hole). Use this part (to prevent eventual oil leakage) when
converting engine to electronic ignition. (Listed in this website.) Remove
points cover, points and OEM pushrod, and install this plug in the pushrod
hole with a medium size hammer. Plug should fit tight in hole, but if it
fits loose, create knurled/raised ridges on the plug with a sharp, flat cold
chisel and hammer, and apply silicone sealant on plug when installing in
the block. No need to reinstall cover and points. NOTE: The alternative
to using this plug is to remove the ignition points and points pushrod, and
place the pushrod on a hard, flat surface, and use a hammer and sharp flat
cold chisel to lightly create knurled raised marks midway on the pushrod.
Then reinstall the knurled pushrod in the engine block with the hammer. Or
a
20 penny common nail cut off to 1/2" length and the end
ground to a bevel will serve the same purpose. The knurled ridges will retain
the pushrod in the hole. Replaces Kohler part # X-702-1 (brass welch
plug). OEM Briggs & Stratton part #'s 231143, 692882. $6.00 each,
plus shipping & handling. [Return

| NOTE:
If a small engine idles well, but fails to rev up or runs erratically at
higher speeds (like it hits and misses, pops and backfires), then chances
are, it needs a new condenser/capacitor. And always install a condenser with
the wire or terminal facing downward so rain water and/or when washing off
engine, water will not enter inside condenser, ruining it. With water inside
the condenser, this will cause the engine to run erratically when revved
up.

FYI - Magneto Coils - To test for
continually of an ignition coil (to see if it's in good condition), use a
multimeter set on the ohm ( ) resistance. To test
the secondary winding (this is the one that usually burns out), insert one
of the multimeter's probes into the spark plug terminal of the coil, contacting
the metal inside the terminal. And touch the second probe of the meter to
the ignition coil's negative (–) terminal. (This is the one not connected
to the primary winding and resistor.) Depending on the type of coil (magneto,
compact, standard size or high output/performance), the meter should read
6,000 to 15,000 ohms. If it does not, the secondary winding is faulty and
the coil needs to be replaced. |

 Armature Ignition
Coil with Molded-In Solid State Electronic Module. Fits Kohler Magnum
engine model M8. NOTE: Install this coil with spark plug wire facing engine
block as shown in photo to the right ->. Set the air gap/clearance between
the magnet in the flywheel and armature laminations with a business card
or a .010" or .25mm brass
feeler gauge. The .010" or .25mm gap produces a stronger
magnetic field through the coil to generate more electricity for a stronger
spark, and so the engine won't misfire. IMPORTANT: Use a new copper
core/non-resistor AC Delco, Autolite or Champion spark plug of the correct
type gapped at .025" for longer coil life. Use of a
resistor type spark plug
will void warranty. And being all older magneto coil spark plug wires have
a metal core, save it off your old coil. With a 12 volt battery coil tower
terminal and boot installed, it can be used for battery ignition.
|
|
| IMPORTANT:
Most failures of a battery-powered ignition coils and/or electronic ignition
control modules are caused by either the use of suppression/carbon-core spark
plug wire(s), resistor-type spark plug(s) [NGK spark plugs], or overcharging
of the electrical system due to a defective voltage rectifier/regulator or
defective [automotive] battery. Therefore, if it's not already equipped,
it's best to install an ammeter/amp gauge to monitor the charging system.
Also, any coil will burn up if the ignition switch is left on with the points
closed for more than a few minutes with the engine not running. To prevent
this from possibly happening and/or for security reasons, use an OFF-ON key
switch and/or a master disconnect switch with a removable key instead of
just a toggle switch to power the ignition system. Also, the coil could burn

  High Quality,
High-Performance Copper or Metal Core 7mm Spark Plug Wire Assemblies Listed
Below. Universal design for many applications. Along with a copper core
spark plug, metal core spark wires provide a stronger spark that allow the
ignition coil to operate cooler, last longer and provide the highest possible
energy to ensure maximum ignition potential. Replace defective coil-to-spark
plug wire or use either of the parts listed below when converting from
Breakerless Ignition or magneto ignition to battery-powered points/condenser
ignition. Suitable for general lawn & garden equipment, small motorized
vehicles or competition garden pulling tractor engines. Fits Kohler engine
models K141, K160/K161,
KV161,
L160/L161, L181, K181,
K241, K301, K321, K330/K331, K341, K361, KT17 (first design), KT17 Series
II, KT19 (first design) KT19 Series II, KT21, K482, K532, K582 and K660/K662
(with wires cut to desired length) and other makes and models of small engines
with a battery-powered ignition system. Don't be fooled by the dark color,
these wires have a metal core that provide 100% voltage to the spark plug
for a strong spark to extend the life of the coil. Copper or metal wire delivers
maximum energy with zero ohm resistance to the spark plug. (FYI - Most OEM
automotive or brightly-colored coil-to-spark plug wires have a suppression/carbon
core that deliver about 40%-50% voltage to the spark plug at peak demand,
which is at open RPM, they've been known to burn up a good coil.) Solid metal
terminals for maximum conductivity and corrosion resistance. Snug-fitting
quality rubber boots keep out dirt and moisture for reliable engine start
up. Engineered for reliability and long life. Spring-lock terminals insure
positive and secure connection through the toughest conditions and multiple
spark plug changes.
 Please specify if you need the rubber neoprene
boot for a 3/4" coil tower (fits most standard-output coils), or 5/8" coil
tower (fits most twin cylinder dual-wire coils and high-output/performance
or OEM automotive electronic ignition coils).

Complete
Battery-Powered Ignition Conversion Kits Listed Below - When
Kohler's OEM magneto or Breakerless Ignition fails, the engine can be converted
to a battery-powered ignition system. battery-powered ignition systems last
longer, produce a stronger spark, and when a part goes bad, it doesn't cost
much to replace. It's a reliable, simple design and there's no guesswork
about it. FYI: battery-powered ignition conversion kits are intended mainly
for various older engines when the OEM magneto or Breakerless Ignition no
longer produce a spark, replacement parts are not available, are very expensive
or cost prohibitive. (Sometimes one must improvise when certain parts are
obsolete.) Also, the most hassle when using battery-powered ignition without
an integrated charging system with the engine to recharge the battery is
the use of a 
battery charger. For a battery to power the ignition, a
small, lightweight and rechargeable
12 volt sealed lead acid (SLA) battery with a minimum 4Ah
(Amp Hour) rating or a small
motorcycle battery can be used.
FYI - Kohler's Breakerless Ignition and Tecumseh's Solid State Ignition (SSI) systems use a key switch that's also made for a self-energizing magneto or magneto-type solid state ignition system. Unlike the OFF-ON-START key switch for a battery-powered ignition system, just like the magneto or solid state ignition systems, with the Breakerless Ignition is self-energizing, and to kill the engine, the key switch grounds out or shorts the [low voltage] circuit between the energizing coil and ignition module. But the battery type OFF-ON-START key switch opens the circuit to kill the engine. So with the battery-powered points and condenser ignition system (along with a 12 volt coil), you will need to use a battery type OFF-ON-START key switch, or an OFF-ON toggle switch or an OFF-ON (security) key switch to power the ignition with a momentary push button starter switch to crank the engine. If swapping out the OEM Breakerless Ignition, magneto or solid state (grounding type) OFF-ON-START ignition key switch for a battery type OFF-ON-START key switch, the wire connectors in the wiring connector will need to be rearranged to match the terminals on the battery type key switch to crank the engine, power the ignition and electrical accessories, and recharge the battery. I've performed this before on some of my customer's ordinary garden tractors and garden pulling tractors, and it works great. Click/tap here for battery-powered ignition wiring diagrams. |

 Several years
ago, an out of town customer brought his John Deere model 110 to our shop
for repairs. This tractor has a Kohler engine model K181 with self-energizing
magneto ignition and a 10 amp alternator charging system. (The ignition coil
and charging coils are mounted on the same armature/stator frame under the
flywheel.) My customer told me that he had another reputable small engine
repair shop in his hometown install a new spark plug, points, condenser and
an entirely new armature/stator assembly, but they could not get the engine
to rev up.
Anyway, I put the tractor on the sturdy
platform table that I
built to make it easier to work on. The engine would start right up and idle
well, but failed to rev up. It would just die out when throttled up. So I
cleaned and inspected the entire carburetor, including clearing out anything
that may have been lodged in the main jet; tried a new Autolite 295 copper
core spark plug gapped at .030"; cleaned and reset the points gap; tried
another new condenser; So after some thoughtful consideration, I came to the conclusion that the OEM Kohler part # 237876 self-energizing magneto ignition/charging system armature/stator assembly is obviously a notorious, bad design. Although this system is still available new from Kohler, Kohler discontinued installing this on certain engines only after a short time. (Apparently, for an obvious reason.)
If you have a similar ignition problem like this and if you're interested, I offer all the parts, including a new compact epoxy-encapsulated 12 volt armature ignition coil kit, that can be used to convert the self-energizing magneto ignition to battery-powered ignition for your tractor.

This is the era of modern wonders, where everything is electronic, transistorized, digitized and miniaturized. Yet even today, many competition garden pulling tractors with an older engine still use the old-fashioned breaker point ignition systems. For other people, the frustration of attempting to keep a breaker point-fired tractor in peak running condition has been enough of a reason to join the electronic/solid state electronic ignition era. Breaker point systems do have some positives, though. ignition points are cheap and somewhat easy to install. And many people are comfortable with installing their own ignition points. The bad side of using ignition points is, besides the ignition points contacts burning, pitting and wearing out, if or when the ignition points lobe on the (Kohler) camshaft and/or the ignition points pushrod become worn, this will narrow the gap on the ignition points, and retard the ignition timing. The ignition points lobe can wear so much that resetting the ignition points at the factory setting of .020" or setting the ignition timing at 20º BTDC becomes impossible. As the point gap gets too narrow, the ignition timing will become retarded (less than the factory setting of 20º BTDC), which will cause the engine to run sluggish and lose power, and when it gets too wide, the timing will become too advanced (more than the factory setting of 20º BTDC), which will cause the engine to run hotter than normal, which could cause premature engine wear and oil burning, eventually resulting in an engine rebuild. There's also less chance of a dangerous fire due to non-existence of ignition points.
Self-energizing small engine magneto armature
ignition coils and battery-powered coils with either points and condenser
or electronic ignition must be used with a metal core spark plug wire and
a copper core/non-resistor spark plug. Most automobiles with electronic ignition
have
suppression/carbon core spark plug wires only to prevent
interference of sensitive electronic components and [AM/FM] radio static.
However, if a suppression/carbon core spark plug wire and/or a
resistor type spark plug
is used with a magneto or battery-powered ignition coil, the coil may operate
at a much higher than normal temperature (too hot to the touch), and either
the coil will fail or the engine will idle well, but hesitate to rev up at
high RPM due to the high resistance in the suppression/carbon core spark
plug wire and/or a resistor
type spark plug. And avoid using a
suppression/carbon core spark plug wire with an electronic
ignition system on a small engine! The reason being is if the suppression/carbon
core spark plug wire becomes extremely weak and deteriorated with very high
resistance, this can cause the ignition coil and possibly the electronic
ignition control module to burn up.
NOTE: With my Universal Solid State Electronic Ignition Module and crank-trigger/flywheel-triggered ignition systems (all listed below), when installed accordingly, the ignition timing is ALWAYS advanced. If it's set or installed retarded, it will NOT automatically advance as soon as the engine starts. If the timing is set retarded, the only way to advance it is by rotating an ignition plate or ignition distributor manually by hand, or automatically by a vacuum canister with intake manifold, or by centrifugal force with flyweights.
When the timing is retarded, the engine may start with no problems, but not idle or rev up too well, and it'll lack sufficient horsepower. Also, with retarded timing, all of the fuel in the combustion chamber will not be burned. Part of the raw fuel will exit out of the exhaust, while the rest will remain in the chamber combustion and cling to the cylinder wall, causing the crankcase lubricating oil to become diluted or thin-out. When this happens, "cylinder wash down" will result. Cylinder wash down is when the gas (or diesel fuel) dilutes the light coating of oil on the cylinder wall, and the piston rings will no longer be adequately lubricated, causing direct metal to metal contact, which will cause them to wear excessively, and cause the cylinder wall have a protruding ridge towards the top, resulting in a smoky, oil burning engine overtime. Cylinder wash down can also happen to a diesel engine when the fuel injectors are purposely "turned up" to increase the fuel delivery so the engine will produce more horsepower. This will cause a lot of black smoke be blown out the exhaust all the time (at idle and especially upon acceleration), which will result in shorter engine life, and eventually, gray exhaust smoke (crankcase oil ash) will be mixed with the black exhaust smoke (resembles partially burnt diesel fuel ash exhaust). It'll run good for a while!
But when the ignition timing is too advanced, this will cause the engine to run too hot, which will likely cause the piston(s) to swell larger than normal, allowing it/them to make metal to metal contact against the cylinder wall, resulting in excessive wear. When the piston wears, it will be too loose in the cylinder, causing a rattling sound. Plus, due to the worn piston, the rings will loose their square edge against the cylinder wall, and become rounded, which will allow oil to be moved to the top of the piston instead of being scraped back into the crankcase. (This is the how the 2nd or middle ring works.) Plus, the rings will lose their expansion against the cylinder wall as well. Eventually, the engine will blow blue or gray smoke out the exhaust, and it will ultimately need to be rebuilt.
If electronic ignition is installed correctly, when the ignition is triggered by the flywheel, this stabilizes the timing, so you won't ever have to worry about it changing. The engine will produce more horsepower and you will have more confidence that the engine will last longer. (As long as an air filter is used, the carburetor is adjusted correctly and the crankcase oil is changed regularly.) So for the utmost precision ignition timing and maintenance-free convenience, flywheel-triggered electronic ignition is the way to go! The high-performance electronic ignition systems offered in this website produce a stable and a very strong spark with the use of microelectronics. They will help the engine to start quicker, idle smoothly and rev up to full RPM with no hesitation whatsoever. Allows a stock coil to perform like a high-performance coil without shortening the life of the coil.
As a matter of fact, electronic ignition works so well, this is why most small engine manufacturers dropped their points and condenser ignition and went to the more dependable and reliable electronic ignition in 1982. And most automotive manufacturers started installing the more dependable and reliable electronic ignition in their vehicles since 1972 (Chrysler products) and 1974 (GM and Ford products).
Tired of cleaning, changing or constantly readjusting the ignition points, and replacing the condenser? Well, upgrade/convert the engine with an A-1 Miller's custom-made, maintenance-free and weather-proof 100% digitized flywheel-triggered electronic ignition system! Shock and moisture resistant, and all it takes is a few simple hand tools to install. In my opinion, getting rid of the points and condenser/capacitor have been the best advance ever in engine technology. FYI - I've designed and sold many various custom-made electronic ignition systems to customers for the past several years and haven't received one complaint about the performance of their engine. Because I use technology that I learned from experiences with my competitive competition pulling tractors (engines) to help factory stock lawn & garden engines perform better. And as a matter of fact, other people have emailed or called me to complain to me about my competitor's replacement electronic ignition systems for Tecumseh engines. They said their technical customer service assistance to resolve the problem was of no help. No joke. Apparently, my competitors haven't quite figured it out yet.
FYI - Kohler's Breakerless Ignition and Tecumseh's (cast iron engine) Solid State Ignition (SSI) systems use a key switch that's also made for a self-energizing magneto or solid state electronic ignition system. Unlike the key switch for a battery-powered ignition system, the Breakerless Ignition is self-energizing, and to kill the engine, the key switch grounds out or shorts the [low voltage] circuit between the energizing coil and ignition module. And the battery-powered key switch opens the circuit to kill the engine. So with the battery-powered points and condenser ignition system (along with a 12 volt coil), you will need to use a battery-powered key switch, or an OFF-ON toggle switch or [security] key switch to power the ignition and a momentary push button starter switch to crank the engine could be used instead. If swapping out the OEM Breakerless Ignition, SSI, magneto or solid state ignition key switch for a battery-powered ignition key switch, the wire connectors in the wiring harness plug will need to be rearranged to match the terminals on the key switch to power the ignition, crank the engine and run other electrical accessories. I've done this before on some of my customer's garden tractors and it works great. Click/tap here for battery-powered ignition wiring diagrams.

12 Volt Replacement Electronic Ignition Kit for Tecumseh Cast Iron Block
Engines | [Top of Page]
New, Improved Design!
NOTE - Being this ignition system requires 12 volts DC negative ground of power, the OEM key switch for the Tecumseh Solid State Ignition (SSI) will not work with any battery-powered ignition systems. The OEM switch used with SSI is actually for magneto ignition, which when the engine is shut-down, it grounds the self-energizing wire connected to the SSI ignition. And battery ignition requires a switch that disconnects the electrical source from the ignition. So with this ignition system, you will need either a battery type OFF-ON-START key switch, or an OFF-ON toggle switch or an OFF-ON key switch (for security purposes; to power the ignition) with a momentary push button starter switch. Go here for choice of switches.
IMPORTANT: Most failures of a battery-powered ignition coils and/or electronic ignition control modules are caused by either the use of suppression/carbon-core spark plug wire(s), resistor-type spark plug(s), or overcharging of the electrical system due to a defective voltage rectifier/regulator or defective [automotive] battery. Therefore, if it's not already equipped, it's best to install an ammeter/amp gauge to monitor the charging system. Also, any coil will burn up if the ignition switch is left on with the points closed for more than a few minutes with the engine not running. To prevent this from possibly happening and/or for security reasons, use an OFF-ON key switch and/or a master disconnect switch with a removable key instead of just a toggle switch to power the ignition system. Also, the coil could burn up if the charging system continually overcharge due to a defective voltage rectifier/regulator or a defective [automotive] battery. Replacement Tecumseh Electronic Ignition Kit with Self-Contained Electronic Ignition . This ignition system requires 12 volts DC negative ground. Includes: new electronic ignition sensor/module and new high quality, 12 volt 3.5 ohm high energy compact epoxy-encapsulated armature ignition coil w/molded-in metal spark plug wire, both fastened to an aluminum ignition plate, new Autolite 295 or Champion J8C spark plug, new momentary push button switch (to crank the engine; optional) and new OFF-ON toggle switch/flip switch or [security] key switch (to power the ignition; optional).

FYI - I've been to many car races, and truck and tractor pulls through the years, and I've noticed that when most drivers start their engine, they would crank it over first with a push button switch, then turn on the ignition switch, and the engine would start every time without hesitation. They start the engine in this order because it has fixed and set in the fully advanced ignition timing position with no retard. Starting the engine this way prevents it from kicking back, which prevent damage to the aluminum starter motor housing. This is how the Tecumseh engines with my custom ignition system listed above should be started without kick back. FYI - I've been receiving several emails and phone calls from people who purchased another type of custom-made electronic ignition system from another source online for their Tecumseh cast iron block engines. If you're experiencing problems with this other type of ignition, you will need to complain to the person you purchased it from. Because being I'm not familiar with the design of another person's custom-made ignition system, the advice I may give you to get your engine running right may not be 100% accurate. It'll be like the mechanic of a reputable Chevrolet car dealer/repair shop trying to tell someone how to fix their poor performing Ford vehicle. By the way - I thoroughly researched and test every custom-made electronic ignition system that I offer in my websites on the test engines in my shop to insure that they work flawlessly, and I have not received any complaints from my customers so far. |
On a Kohler K-series K241, K301, K321 and K341 engine, with points/condenser ignition, when the points lobe on the camshaft wears, the ignition timing cannot be advanced enough to allow the engine to produce full power. To fix this so the engine will be in its original condition, a [used] Kohler camshaft in good condition with an unworn points lobe will need to be installed. But to replace the cam, the entire engine must be completely disassembled (except for removal of the governor components and valves), the end-play of the cam and valve clearances will need to be checked and perhaps reset, new gaskets will need to be installed and the points gap will need to be reset. Or you can avoid all of this and install one of A-1 Miller's custom flywheel-triggered electronic ignition kits that may outlast your engine and require no periodic adjustments. With an electronic ignition kit that replace the points, you can reuse your ignition coil, spark plug wire and spark plug. Please scroll down for information and options.

Information About Kohler's Breakerless Ignition - (Scroll down for more information on this.)
If a Kohler flywheel has no projection (slightly angled hump) or large bolt head for Breakerless Ignition, but does have the 3/4" wide area between the fins and ring gear, or a billet steel flywheel, to use a magnetic pickup coil, 3-wire inductive (detects iron/steel) proximity sensor, a small, short steel Phillips or button head socket (Allen) Head screw and a minimum 1/4" length aluminum spacer secured with a split lock washer or high strength liquid threadlocker (Red Loctite, Permatex or equivalent) can be used as the signal detection for the flywheel-triggered electronic ignition. A steel dowel pin or knurled steel pin could be used instead of a screw or spiral pin, but because of exerted centrifugal force, the screw would be more secure due to its thread retention. FYI - Store a container of liquid threadlocker or Super Glue upright and not laying flat. The capped tip will not dry out and clog when stored upright.
The curvature or dome shaped heads of button- and Phillips-head screws makes them ideal for use on a trigger disc or flywheel. Spark occurs at the leading (high side) edge of the hump or screw, and not in the center of the hump or screw. When the cube-shaped proximity sensor is at the leading edge of the hump and when the S mark on the flywheel is aligned with the raised line on the bearing plate, it is at this point the timing is at 20º BTDC. But if the flywheel has the 3/4" wide area, but no projection (hump) or large bolt head, with the magnetic pickup coil or cube-shaped proximity sensor installed on the bearing plate and the 20º BTDC mark on the flywheel aligned with the raised line on the bearing plate.
When using an inductive proximity sensor, being these type of sensors detect a farther distance (up to 3/16") than a magnetic pickup coil, install a 3/4" length steel screw with a 1/4" length aluminum spacer (to retain flywheel balance). This will extend the detectable target 1/4" above the surface of the flywheel to prevent an out of time spark occurrence by part of the flywheel itself. Or if using a non-magnetic pickup coil, 3-wire hall effect proximity sensor or a non-magnetic electronic ignition sensor/module, a small ring magnet fastened by a small screw can be used to create a rotating magnet detection target. The head of the screw will become magnetized.
An 8-32 UNC and 10-32 UNF x 1/2" length screws with a split lock washer (and small magnet) only weighs about 1/10 of an ounce or 2.8 grams, so this will not make the flywheel significantly noticeably or dangerously out of balance. But if you're concerned about the flywheel being out of balance with the trigger screw/bolt, pin or screw w/ring magnet installed, the flywheel can be static balanced by weighing the flywheel and screw/bolt, pin or screw w/ring magnet separately on a precision scale, make a note of the exact weight of each item, and either install a stainless steel screw of the same exact weight as the trigger screw and magnet on the opposite side of the flywheel (180º apart), or drill a couple of shallow holes into the flywheel next to or beside the installed trigger screw/bolt, pin or screw w/ring magnet to put the flywheel back in balance. Make sure the flywheel is perfectly clean of dirt and debris, too. Actually, it's best to have the flywheel with the trigger screw/bolt, pin or screw w/ring magnet installed dynamically precision spin-balanced on a automotive balancing machine. Again, make sure the flywheel is perfectly clean of dirt and debris.
And for the ignition timing to be set at 20º BTDC, with the S mark on the flywheel and raised line on the bearing plate aligned, the screw will need to be located at 2-3/8" when using a magnetic pickup coil or proximity sensor. This setup can be adapted to a Kohler engine with the flywheel that has the starter/generator and gear starter alike. Or it can be applied to an engine with a steel flywheel for competition pulling. And the mounting holes in the angled bracket for the magnetic pickup coil can be elongated for precise adjustment/setting of the timing. If there's already a projection (hump) or large bolt head on the flywheel, then there's no need to modify the flywheel for this conversion or upgrade. If they're not already present, new 10-24 UNC threads will need to be drilled and tapped in the two raised bosses in the bearing plate to mount the bracket for the sensor's bracket.
Information About Converting from a Failed OEM Kohler Breakerless Ignition System to a Custom-Made Battery-Powered Electronic Ignition System or Battery-Powered Points/Condenser Ignition System | [Top of Page]
The energizer wire that come from the stator under
the flywheel for Kohler Breakerless Ignition or Tecumseh Solid State Electronic
Ignition Module generates about 250 volts (serious) while the engine is running
at full governed speed. Actually, the primary circuit in virtually all magneto
ignition coils generate anywhere from 200 to 400 volts. So do not touch this
wire or terminal with one bare hand and the engine itself with your other
bare hand while the engine is running! Electrocution or death could occur.
It is not needed for any of A-1 Miller's crank-trigger ignition systems.
So snip off this wire or tape up the terminal.
NOTE: On all Kohler engines
with Breakerless Ignition, there is a tiny (3/16") brass cup/expansion cup
plug in the points pushrod hole. This is to prevent oil from leaking out
the crankcase with Breakerless Ignition. This plug MUST be removed to use
the points pushrod when converting to points/condenser ignition. To prevent
damage to certain moving parts inside the engine and possible eventual internal
engine failure, do not push this plug into the crankcase! It may NOT drain
out with the oil either. If it is pushed into the crankcase, the oil pan
will need to be removed in order to remove the brass plug. To remove this
plug from outside the engine, carefully and gently drill a 7/64" pilot
hole through the plug, then use a #6
self-tapping drywall screw (a small
ordinary self-tapping screw may not work as well) with
small Vise-Grips or a small
crowbar or
pry bar hooked to the screw to pull the plug out of the
hole. Because without drilling the hole first, the self-tapping drywall screw
by itself may not be able to bore a hole through the plug without pushing
it deeper into the pushrod hole. And do not force the drill bit into the
plug or it could get pushed inside the crankcase! Use a new drill bit if
necessary. When the plug is removed, a 3/16" drill bit or hand reamer may
need to be used to clean out any debris/rust from the pushrod hole. After
the points is properly installed, and with the piston positioned at TDC on
the compression stroke, set the point gap at .020", or better yet,
set the ignition timing at 20º
BTDC, and definitely use a copper core/non-resistor spark plug of the
correct type gapped at .035".
| Custom-Made Electronic Ignition Kits (below) for Converting
Kohler engine models K241, K301, K321, K341 or K361 to Flywheel-Triggered
Ignition, if the engine originally came with points/condenser ignition or
Breakerless Ignition. Do away with the old fashioned points and condenser
ignition, or defective and cost-prohibitive Breakerless Ignition components,
and convert your engine to the reliability, dependability and durability
of flywheel-triggered ignition!
This ignition system operates with full 12 volts. This is a thoroughly
tested, researched and proven reliable ignition system invented by A-1 Miller's
for ordinary lawn & garden engines and competition pulling engines. With
most tractors, the ignition conversion can be made with the engine in the
tractor. The only modifications that need to be done is the flywheel shroud
needs to be loosened to access and replace the Trigger Module, and two holes
will need to be drilled and tapped with the 2 supplied screws in the kit.
To install this replacement ignition system; the ignition coil mounts in
place of the Breakerless Ignition coil; the proximity cube sensor/bracket
mounts in place of the Breakerless Ignition Trigger Module, which is located
at the 10:30 position on the bearing plate; and two 9/64" holes will need
to be drilled and tapped (with the two self-threading screws are supplied
with the kit) on the backside of the bearing plate, on the left side when
facing the flywheel, to mount the GM HEI ignition control module. Be sure
to install small flat washers between the module and mounting surface to
provide an "air space" so the module will remain cool while in
operation.
IMPORTANT: Most failures of battery-powered ignition coils and/or electronic ignition control modules are caused by either the use of suppression/carbon-core spark plug wire(s), resistor-type spark plug(s), or overcharging of the electrical system due to a defective voltage rectifier/regulator or defective [automotive] battery. Therefore, if it's not already equipped, it's best to install an ammeter/amp gauge to monitor the charging system. Also, the coil and module may burn up if the ignition switch is left on for more than a few minutes with the engine not running. To prevent this from possibly happening and/or for security reasons, use an OFF-ON key switch and/or a master disconnect switch with a removable key instead of just a toggle switch to power the ignition system. Also, the coil could burn up if the charging system continually overcharge due to a defective voltage rectifier/regulator or a defective [automotive] battery. List of Parts in Kit Includes:

Designed for Kohler engine models K181, K241, K301, K321 (that originally came with Breakerless Ignition).
Ignition Parts Include: (Prices are as of 2/7/25)
NOTE - Being this ignition system requires 12 volts DC negative ground of power, the OEM key switch for Breakerless Ignition will not work with any battery-powered ignition systems. The switch used with Breakerless Ignition is actually a magneto ignition switch, which when the engine is shut-down, it grounds the self-energizing wire connected to the ignition. And battery ignition requires a switch that disconnects the coil from the electrical source (battery). So with this ignition system, you will need either a battery type OFF-ON-START key switch, or an OFF-ON toggle switch or an OFF-ON key switch (for security purposes; to power the ignition) with a momentary push button starter switch. Go here for choice of switches. IMPORTANT: Most failures of a battery-powered ignition coils and/or electronic ignition control modules are caused by either the use of suppression/carbon-core spark plug wire(s), resistor-type spark plug(s), or overcharging of the electrical system due to a defective voltage rectifier/regulator or defective [automotive] battery. Therefore, if it's not already equipped, it's best to install an ammeter/amp gauge to monitor the charging system. Also, any coil will burn up if the ignition switch is left on with the points closed for more than a few minutes with the engine not running. To prevent this from possibly happening and/or for security reasons, use an OFF-ON key switch and/or a master disconnect switch with a removable key instead of just a toggle switch to power the ignition system. And the coil could burn up if the charging system continually overcharge due to a defective voltage rectifier/regulator or a defective [automotive] battery.

A-1 Miller's Custom-Made Flywheel-Triggered Electronic Ignition Conversion Kit for Kohler opposed twin cylinder engine models KT17 (first design), KT17 Series II, KT19 (first design), KT19 Series II, KT21, and perhaps opposed twin cylinder Magnum engines with the KT-series flywheel installed, except generator engines. [Top of Page]
Designed
to convert a 12 volt points and condenser ignition system into the more reliable
and dependable 100% digital 12 volt electronic ignition system.
Points and condenser cannot be used with this ignition system. Remove the
points and condenser and cover the points pushrod hole with the supplied
block-off plate with silicone sealant. With this custom electronic ignition
conversion kit, the edge of the flywheel must be drilled and tapped with
installation for a small screw and magnet. This type of electronic ignition
must be triggered off the flywheel. There is no other way of making it happen.
If you can't find someone local that can do this for you,
A-1 Miller's offer this service if you won't mind bringing
your engine to us.
This ignition system is very reliable, works flawlessly and, may extend and/or outlast the life of the engine. Replaces points and condenser. This high-performance ignition system have been thoroughly tested under extreme conditions, and produces a stable and a very strong spark with the use of microelectronics, even with the stock OEM canister ignition coil, helping the engine to start quicker, idle smoothly and rev up to full RPM with no hesitation whatsoever. This revolutionizes the ignition system for the opposed twin cylinder Kohler engines! With points (and condenser) ignition, the factory setting for the timing on these engines is 23º BTDC. Being the points is operated off the camshaft, and being there's slight free-play/clearance between the gear teeth on the camshaft and crankshaft (which is normal), the ignition timing can fluctuate a few degrees, resulting in slight loss of engine power. And sometimes the lobe for the points pushrod on the cam will wear, which will make setting the timing at full 23º BTDC impossible, which will also cause the engine to lose power. (Both of these are confirmed in the official Kohler KT17, KT17 Series II, KT19 and KT19 Series II service manual.) And with a worn points lobe, the entire engine will need to be completely disassembled to replace the camshaft. This custom-made electronic ignition system maintains the timing at 23º BTDC at all times because it operates off the flywheel, which is driven by the crankshaft. With this custom ignition system, the timing will never change. It works the same as crank trigger ignition. The OEM Kohler [4.0 ohm] opposed twin cylinder canister ignition coil works excellent with this ignition sensor/module to produce a very strong spark. Allows a stock coil to perform like a high-performance coil without shortening the life of the coil. To prevent burning up the electronic ignition module, it MUST be used with a coil having a minimum of 3.0 ohm resistance.
KT-series Electronic Ignition Option #1 - This electronic ignition conversion kit use two round supports that fastens on the side of the valve spring compartment, to mount the module/sensor onto. (Pictured above.) This kit is designed specifically for the KT17 (first design), KT19 (first design) and KT21 engines. But can also be used on the KT17 Series II and KT19 Series II engines, and Magnum opposed twin cylinder engines with the KT-series flywheel installed. Kit includes: New hall effect electronic ignition sensor/module fastened on adjustable/slotted aluminum mounting plate, two 10-24 UNC screws w/flat washers and lock washers, two aluminum spacers, target screw w/magnet and rubber washer (prevents the delicate magnet from possibly breaking when lightly fastened against the uneven rough casting of the flywheel), two new Autolite 26 or Champion 25 (RV17YC) spark plugs, and points pushrod hole block-off plate (use with silicone sealant). Use this ignition system with the OEM off-ignition-start key switch and dual wire ignition coil. All replacement ignition parts are readily available. And if this custom electronic ignition is used in a garden tractor with a longitudinal engine, such as Cub Cadet, Economy Power King, Ford, hydrostatic-drive John Deere, MTD Farm King Model 960, Pennsylvania Panzer, Meteor, Copar, etc., it'll be easier to install if the engine is removed from the tractor. NOTE: If your engine is hard to start, looses horsepower and dies when hot, and restarts when cooled, and repeats this over and over, then chances are, it needs a professional valve job performed with the valve clearances reset to factory specs. Because just installing electronic ignition will not fix a faulty valve problem. Please contact A-1 Miller's if you're interested in having a professional valve job performed on your Kohler opposed twin cylinder engine.
INSTALLATION INSTRUCTIONS for KT17 (first design), KT19 (first design) and KT21 engines. This option can also be used on the KT17 Series II and KT19 Series II engines, and Magnum opposed twin cylinder engines with the KT-series flywheel installed. Video of this ignition system installed on a running engine coming later. Scroll down to read the wiring connection instructions or click here to view and print out these installation instructions.
Use a
Sharpie metallic silver permanent ink marker to locate
and install the 
trigger screw
w/magnet and rubber washer on the flat area on the flywheel above the
T mark as shown in the photo to the right ->. This will place the
ignition timing in alignment with the center of the electronic ignition
sensor/module when the S mark on the flywheel is in exact alignment
with the roll pin on the cylinder (which is positioned at 23º BTDC).
The screw head in the magnet is magnetized to trigger the spark. There is
no need to remove the flywheel to drill and tap the threads to accept the
supplied 6-32 UNC trigger screw.
Click/tap here to learn
how to professionally cut new threads. To prevent from possibly breaking
off drill bit or tap, secure the flywheel so it does not rotate one way or
the other while drilling hole and/or cutting threads! NOTE: The rubber
washer prevents the delicate magnet from possibly breaking when lightly fastened
against the uneven rough casting of the flywheel. IMPORTANT: To prevent from
possibly loosening, secure screw in flywheel or rotating disc with
high strength liquid threadlocker
(Red Loctite, Permatex or equivalent). Tighten
screw just when the rubber begin to bulge, and allow the Loctite to dry and
harden overnight. The hall effect electronic ignition sensor/module is activated
by the South pole of the magnet, so do not remove the magnet from the screw!
FYI - Store a container of liquid threadlocker or Super Glue upright and
not laying flat. The capped tip will not dry out and clog when stored
upright.
Being there are no two bosses
on the cooling fins of the #1 cylinder (right side of engine when facing
the flywheel) of the KT17 (first design) and KT19 (first design) engines,
use the flat casting on the side of the valve spring compartment on the #1
cylinder facing the flywheel to mount the two supports with the electronic
ignition sensor/module adjustable mounting plate. See the
[mock up] photo in this section.
KT-series Electronic Ignition
Option #2 - This electronic ignition conversion kit use a somewhat long square
steel tube support that mounts on the 2 bosses on the #1 cylinder, to mount
the module/sensor onto. (Pictured above.) This kit is specifically designed
ONLY for the KT17 Series II and KT19 Series II engines (and perhaps Magnum
engines with the KT-series flywheel installed). Kit includes: New hall effect
electronic ignition sensor/module fastened on aluminum mounting plate and
square steel tubing, two 1/4" x 1-1/2" length grade 8 bolts w/lock washers,
target screw w/magnet and rubber washer (prevents the delicate magnet
from possibly breaking when lightly fastened against the uneven rough casting
of the flywheel), two Autolite 26 or Champion 25 (RV17YC) spark plugs,
and points pushrod hole block-off plate (use with silicone sealant). Use
this ignition system with the OEM off-ignition-start key switch and dual
wire ignition coil. All replacement ignition parts are readily available.
And if this custom electronic ignition is used in a garden tractor with a
longitudinal engine, such as Cub Cadet, Economy Power King,
Ford, hydrostatic-drive John Deere, MTD Farm King Model 960, Pennsylvania
Panzer, Meteor, Copar, etc., it'll be easier to install if the engine is
removed from the tractor.

A new way to revolutionize the ignition system on virtually any small gas engine! Virtually trouble- and maintenance-free, and water-proof. These ignition modules/sensors is a small, lightweight, compact and completely self-contained electronic ignition system built with the latest state-of-the-art engineering with the use of microelectronics. Fits entirely on the engine block; no ignition box and additional wiring to clutter the engine compartment because the electronic ignition control module and pickup coil/sensor are contained in the same sealed casing. The self-contained Dynatek Dyna S sensor/module produce a stable and a very strong spark with the use of microelectronics. They will produce a stronger spark to help the engine to start quicker, idle smoothly and rev up to full RPM with no hesitation whatsoever. Allows a stock coil to perform like a high-performance coil without shortening the life of the coil.
These maintenance-free crank-trigger electronic ignition setups have been thoroughly tested and proven very reliable for general lawn and work, and all classes of single and opposed twin cylinder competition pulling engines. One sensor/module is needed for an opposed twin cylinder engine, and two modules/sensors spaced precisely at 90º apart are required for V-twin engines. These are the same ignition systems used by professional pullers everywhere. Reliable at high RPM, these electronic ignition modules provide unlimited RPM. They will allow the ignition system to operate at the speed of electricity (which can be anywhere from about 50% to 99% of the speed of light, depending upon the quality of the electronic components and wiring connections).
Spark occurs when the magnet embedded in an aluminum locking set screw collar (magnet ring), which is much like an automotive reluctor ring, that's fastened on the crankshaft's PTO end passes the sensor/module. These sensors/modules packs a lot of punch and allow the ignition system operate at 100% efficiency for a stronger spark. When wired correctly, it's normal for the flywheel- and crank-trigger ignition systems to make a spark when first powered up. And if it makes a spark as the sensor passes the metal target object, then the ignition system is working as it should.
NOTE: With all of my crank-trigger ignition systems (all listed below), when installed accordingly, the ignition timing is ALWAYS advanced. If it's set or installed retarded, it will NOT automatically advance as soon as the engine starts. If the timing is set retarded, the only way to advance it is by rotating an ignition plate or ignition distributor manually by hand, or automatically by a vacuum canister with intake manifold, or by centrifugal force with flyweights.
The Dynatek Dyna S sensor/module operates with 12-1/2 to 15 volts DC negative ground, and requires an ignition coil with a minimum 3.0 ohm resistor. Using a coil with less than 3.0 ohm of primary resistance for a long period of time will cause the module to overheat and the engine may misfire until it cools down, or the sensor/module might fail prematurely. A metal core spark plug wire and copper core/non-resistor spark plug should be used. If the voltage drops below the minimum requirement for either sensor/module, the engine may idle well, but not rev up, or the engine may run erratic. Either sensor/module can be used with a standard-output/stock or (40,000 volt) high-output/performance or OEM automotive electronic ignition coil, as long as it has a 3.0 ohm internal primary resistor, or connected to a ballast resistor, resulting in 3.0 ohm of resistance.
Maintenance-Free 12 Volt Dynatek Dyna S Crank-Trigger Electronic Ignition Installation Instructions -
A-1 Miller's universal flat
aluminum mounting plate with the self-contained Dynatek Dyna S ignition
sensor/module kits can be adapted for use on various makes and models of
one or two cylinder (twin opposing cylinders) small engines. Being there
are so many different bolt patterns on the PTO end of Kohler and other makes
and models of small engines, these are not a simple "one kit fits all" bolt-on
ignition setup. Therefore, customer will need to locate and drill holes in
the mounting plate in alignment with the bolt holes on the PTO end of the
engine block. If there are no bolt hole(s) on the PTO end of the block, they
will need to be drilled and tapped.
Click/tap here to learn
how to professionally cut new threads. For strength and durability, a
minimum of 1/4" bolts (thread size) should be used to fasten mounting plate
to PTO end of engine block. Locate and drill (machine) slotted adjustment
holes in the mounting plate. And then drill and cut 4-40 NC threads in the
mounting plate to fasten the sensor/module. Air gap/clearance between the
sensor/module and locking set screw collar w/embedded magnet is .010" or
.25mm - .050" or 1mm. sensor/module may not operate or engine may misfire
if gap is wider than .060". NOTE: Do not allow
sensor/module to make contact with locking set screw collar w/embedded magnet
while engine is running!

kits that operate off the flywheel end of the engine. These can be used for
ordinary lawn & garden engines or stock competition pulling
engines.
Dynatek Dyna S Crank Trigger Ignition Kit and Systems for a Single Cylinder Engine listed below. These ignition systems works flawlessly and may outlast the life of the engine. These ignition systems operate off the PTO end of the crankshaft and is mainly for competition pulling engines that have nothing on the PTO end of the crankshaft. NOTE: Slotted mounting holes will be machined in the mounting plate. If the bolt holes in the PTO end of the block don't match the ones in the plate or if bolt holes are not present, then new bolt holes will need to be drilled and tapped in the engine block. Click/tap here to learn how to professionally cut new threads. Can be used on Kohler 10-16hp single or opposed twin cylinder horizontal shaft engines. Set the clearance between the module and locking collar at .010" or .25mm - .050" or 1mm. NOTE: For easier setting of the timing with the old style electronic ignition , use a permanent ink marker (Sharpie, Magic Marker, Marks-A-Lot, etc.) on the side of the locking collar in alignment with the magnet to indicate the location of the magnet. IMPORTANT - Gently rotate the flywheel back and forth by hand to check and see that the module does not make contact with the locking collar. Do not allow the module make contact with the locking collar while the engine is running! IMPORTANT - The module will burn up after a few minutes up if the ignition switch is left on with the engine not running. To prevent this from possibly happening and/or for security reasons, use an OFF-ON key switch and/or a master disconnect switch with a removable key instead of just a toggle switch to power the ignition system.
Designed
to convert a 12 volt points and condenser ignition system into the more reliable
and dependable 100% digital 12 volt electronic ignition system.
Points and condenser cannot be used with this ignition system. Remove the
points and condenser and cover the points pushrod hole with the supplied
block-off plate with silicone sealant.
Crank Trigger Ignition with the Self-Contained Dynatek Dyna S Sensor/Module Fastened on an Aluminum Mounting Plate, Triggered by an Embedded Magnet in a Locking Set Screw Collar. Requires 12 volts DC negative ground of power and an ignition coil with minimum 3.0 ohms resistance. Mounting plate fastens on the PTO end of engine block, and coil mounts remotely on side of flywheel shroud or elsewhere in engine compartment. This high-performance ignition system have been thoroughly tested under extreme conditions, and produces a stable and a very strong spark with the use of microelectronics, helping the engine to start quicker, idle smoothly and rev up to full RPM with no hesitation whatsoever. Allows a stock coil to perform like a high-performance coil without shortening the life of the coil. Ignition coil not included, purchase separately or customer use their own [minimum 3.0 ohm] ignition coil. Module may burn up if the wrong coil is used. Click here to learn how to test the ohm resistance of a coil. Set the air gap/clearance between sensor and magnet in locking set screw collar at .010" or .25mm - .050" or 1mm, and set spark plug gap at .035". NOTE: For easier setting of the timing with this electronic ignition module, use a permanent ink marker (Sharpie, Magic Marker, Marks-A-Lot, etc.) on the side of the locking collar in alignment with the magnet to indicate the location of the magnet. IMPORTANT - Connect the RED wire to the coil positive [+] terminal (which connects to the ignition switch and battery positive (+) post), and connect the BLACK wire to the coil negative (–) terminal. IMPORTANT: The module will burn up after a few minutes up if the ignition switch is left on with the engine not running. To prevent this from possibly happening and/or for security reasons, use an OFF-ON key switch and/or a master disconnect switch with a removable key instead of just a toggle switch to power the ignition system. When the ignition unit is installed and wire(s) correctly connected, turn the ignition switch on to supply electricity to the coil, and rotate the flywheel back and forth by hand so the magnet passes the module and observe for a strong, "snappy" blue spark at the spark plug's tip. Please specify diameter of crankshaft PTO end for locking set screw collar w/embedded magnet. Most common OEM crankshaft PTO end diameters are 1" and 1-1/8", but 3/4", 1-1/4", 1-3/8", 1-7/16" and 1-1/2" are rare. Most billet steel crankshafts have a 1-1/4" or 1-1/2" diameter raised shoulder. IMPORTANT: Use a new copper core/non-resistor AC Delco, Autolite or Champion spark plug of the correct type gapped at .025" for longer coil life. Use of a resistor type spark plug will void warranty. This ignition setup is shown above. Mounting plate available with 3-1/2" or 4" bolt hole spacing, but customer may have to drill and tap the block to mount the crank-trigger or modify the bracket if necessary. All replacement ignition parts are readily available. Video of this ignition system installed on a running engine coming later. $130.00 per kit, plus shipping & handling.

Self-Contained and Compact Crank Trigger Ignition System with the Dynatek Dyna S Sensor/Module Incorporated with a High Energy Ignition Coil, Both Fastened on an Aluminum Mounting Plate, Triggered by an Embedded Magnet in a Locking Set Screw Collar. Requires 12 volts DC negative ground of power. Thoroughly tested and proven to be very reliable. The high energy armature ignition coil is fastened above the Dynatek Dyna S sensor/module on the same aluminum ignition plate. This ignition system operates off the PTO end of the engine and is mainly for competition pulling engines that have nothing on the PTO end of the crankshaft. This ignition system "cleans up" the engine compartment. No remotely-mounted coil or extra wiring needed. Can be mounted above or on right side of crankshaft. This high-performance ignition system have been thoroughly tested under extreme conditions, and produces a stable and a very strong spark with the use of microelectronics, even with the compact epoxy-encapsulated armature ignition coil, helping the engine to start quicker, idle smoothly and rev up to full RPM with no hesitation whatsoever. The Dynatek Dyna S sensor/module is triggered by a small magnet embedded in an aluminum locking set screw collar (magnet ring) that's fastened on the crankshaft. All replacement ignition parts are readily available. Mounting plate available with 3-1/2" or 4" bolt hole spacing. But customer may have to drill and tap the block to mount the crank-trigger or modify the bracket if necessary. Click/tap here to learn how to professionally cut new threads. Simple wiring connections: Connect the RED wire to the ignition switch (which connects to the battery positive (+) post), and connect the BLACK wire to the grounding-type kill switch. The ignition system is grounded to the engine through negative (–) battery post. IMPORTANT: The module will burn up after a few minutes up if the ignition switch is left on with the engine not running. To prevent this from possibly happening and/or for security reasons, use an OFF-ON key switch and/or a master disconnect switch with a removable key instead of just a toggle switch to power the ignition system. Set the air gap/clearance between sensor and magnet in locking set screw collar at .010" or .25mm - .050" or 1mm, and set spark plug gap at .035". NOTE: For easier setting of the timing with this electronic ignition module, use a permanent ink marker (Sharpie, Magic Marker, Marks-A-Lot, etc.) on the side of the locking collar in alignment with the magnet to indicate the location of the magnet. When the ignition unit is installed and wire(s) correctly connected, turn the ignition switch on to supply electricity to the coil, and rotate the flywheel back and forth by hand so the magnet passes the module and observe for a strong, "snappy" blue spark at the spark plug's tip. The locking collar w/embedded magnet is available for all diameters of PTO end of the crankshaft. IMPORTANT: Use a new copper core/non-resistor AC Delco, Autolite or Champion spark plug of the correct type gapped at .025" for longer coil life. Use of a resistor type spark plug will void warranty. Please specify diameter of crankshaft PTO end for locking set screw collar w/embedded magnet. Most common OEM crankshaft PTO end diameters are 1" and 1-1/8", but 3/4", 1-1/4", 1-3/8", 1-7/16" and 1-1/2" are rare. Most billet steel crankshafts have a 1-1/4" or 1-1/2" diameter raised shoulder. $250.00 per kit, plus shipping & handling.

Crank
Trigger Electronic Ignition System with the Self-Contained Dynatek Dyna S
Sensor/Module and an Incorporated High Energy Ignition Coil Fastened on an
Angled Aluminum Mounting Plate, and Locking Set Screw Collar w/Embedded Magnet
for Kohler Engine Models KT17 (first design), KT17 Series II, KT19 (first
design), KT19 Series II, KT21, M18 and M20 Competition Pulling Engines
Only. Requires 12 volts DC negative ground of power. Being the
aftermarket and OEM Magnum M18 and M20 solid state electronic armature ignition
coils will hold up to around 3,600 RPM, when used at higher RPM, the secondary
windings within the coil tend to overheat, causing the coil to eventually
fail. But this custom-made ignition system helps the engine to rev to its
maximum without failing. It works flawlessly and may outlast the life of
the engine. It operates off the PTO end of the engine and is mainly for
competition pulling engines that have nothing on the PTO end of the crankshaft.
The high energy dual-spark plug wire compact armature ignition coil is fastened
above the Dynatek Dyna S module on a sturdy aluminum mounting plate; cleans
up the engine compartment. IMPORTANT: When ordering,
please indicate the bolt hole spacing (measurement) for mounting the angle
bracket to the rear closure plate on the PTO end of the engine. Or customer
can machine their own adjustable slotted mounting holes. This
high-performance ignition system have been thoroughly tested under extreme
conditions, and produces a stable and a very strong spark with the use of
microelectronics, even with the compact armature ignition
coil, helping the engine to start quicker, idle smoothly and rev up to full
RPM with no hesitation whatsoever. The Dynatek Dyna S sensor/module is triggered
by a small magnet embedded in an aluminum locking set screw collar (magnet
ring) that's fastened on the crankshaft. Use this setup for durability when
the solid state armature ignition coil keeps failing for no apparent reason.
All replacement ignition parts are readily available. Simple one wire hook-up;
RED wire on sensor/module connects to
12 volt ignition switch (which connects to the positive (+) battery post).
This ignition system is grounded through the engine. NOTE: For easier setting
of the timing with this electronic ignition module, use a permanent ink marker
(Sharpie,
Magic Marker,
Marks-A-Lot, etc.) on the side of the locking collar in
alignment with the magnet to indicate the location of the magnet. Kit includes:
Dynatek Dyna S sensor/module and high energy dual wire epoxy-encapsulated
armature ignition coil with two molded-in metal core coil-to-spark plug wires
and 90º spark plug terminals/boots fastened on aluminum mounting plate,
and small magnet embedded in an aluminum locking set screw collar (magnet
ring), and new battery ignition OFF-IGNITION-START key switch (do not reuse
OEM Magnum solid state ignition key switch with this system) or momentary
push button starter switch (to crank the engine), OFF-ON toggle switch or
an OFF-ON key switch (for security purposes; to power the ignition) and fully
insulated male and female
slip-on spade crimp-type wire connectors (to easily
connect/disconnect the ignition system to/from the electrical source). Remove
the OEM solid state armature ignition coil and aluminum bracket. They will
serve no purpose with this kit. Use with metal core spark plugs gapped at
.030" each. When the ignition unit is installed and wire(s) correctly connected,
turn the ignition switch on to supply power to the coil, and rotate the flywheel
back and forth by hand so the magnet passes the module and observe for a
strong, "snappy" blue spark at the spark
plug's tip(s). Please specify diameter of crankshaft PTO end for locking
set screw collar w/embedded magnet. IMPORTANT: Use a new copper
core/non-resistor AC Delco, Autolite or Champion spark plug of the correct
type gapped at .025" for longer coil life. Use of
resistor type spark plugs
will void warranty. Coil can withstand high engine vibration. Please
specify diameter of crankshaft PTO end for the

Replacement
Dynatek Dyna S Sensor/Modules. IMPORTANT: Use with minimum 3.0 ohm coil
to prevent burning up module.
Click here to learn how to check the primary ohms resistance
in a coil. Simple wiring instructions: Connect the
RED wire to the coil positive [+] terminal
(which connects to the ignition switch and battery positive (+) post), and
connect the BLACK wire to the coil negative (–) terminal, and
self-grounding kill switch (pulling tractor). There are no other wire(s)
that connects to the negative (–) terminal on the coil. The mounting
base of the sensor/module is grounded to the engine and negative (–)
battery post.
IMPORTANT
- Use dielectric grease between the module/sensor and aluminum mounting plate
to dissipate the normal operating heat with cool circulating air. And the
module will burn up after a few minutes up if the ignition switch is left
on with the engine not running. To prevent this from possibly happening and/or
for security reasons, use an OFF-ON key switch and/or a
master disconnect switch with a removable
key instead of just a toggle switch to power the ignition system.
To test if the module is good or bad, with an analog or digital
multimeter set on the Ohms resistance, connect one lead to the BLACK
wire and the other lead to the mounting base. If the meter shows no resistance,
the module is good. But if it shows resistance, the module is bad (shorted
out internally). Use with aluminum locking set screw collar w/embedded magnet
(magnet ring; listed below) on PTO end of crankshaft to trigger the spark.
Aluminum
Locking Set Screw Collar w/Embedded Trigger Magnet (Magnet Ring). Use with
Dynatek Dyna S, hall effect electronic ignition module or hall effect proximity
sensors. When ordering, please specify diameter of crankshaft PTO end or
shaft it's to be mounted on. Most common Kohler crankshaft PTO end diameters
are 1", 1-1/8", but 3/4", 1-1/4", 1-3/8", 1-7/16" and 1-1/2" are rare. Most
billet steel crankshafts have a 1-1/2" diameter PTO end (raised shoulder).
NOTE: For easier setting of the timing with the electronic ignition module,
use a permanent ink marker
(Sharpie,
Magic Marker,
Marks-A-Lot, etc.) on the side of the locking collar in
alignment with the magnet to indicate the location of the magnet. Other sizes
available. $30.00 each, plus shipping & handling. Please

How to Test for Spark and Set the Timing for the electronic ignition
sensor/modules - After either setup is installed on the engine and
electricity is supplied, simply rotate the locking set screw collar w/embedded
magnet (loose) on the crankshaft back and forth by hand. Each time the embedded
detector/trigger magnet passes the sensor/module, spark should occur. NOTE:
Do not use a
battery charger alone for power to perform this test. Battery
chargers constantly switch between high and low voltage at 60 cycles per
second, and the module sees this as the ignition being switched on and off,
resulting in a continuous array of sparks.
A simple and precise way to set the ignition timing STATICALLY (engine not running) for either sensor/module -
How to accurately set the ignition timing STATICALLY for the Electronic Ignition Module or Inductive 3-Wire Proximity sensor/module - (This is also how to test if the sensor/modules or the ignition system is functioning or not.)
How to precisely set the ignition timing DYNAMICALLY (engine running) using an automotive inductive timing light for either sensor/module. (This is the most accurate way to set the timing.) NOTE: Timing can be checked, but not set while the engine is running! Do not allow sensor/module to make contact with the locking set screw collar w/embedded magnet while engine is running! -
Magnetic pickup coils
and round-shaped proximity sensors are very sensitive to mechanical damage
(and electrical damage if connected wrong). For
magnetic pickup coils, set the air gap/clearance from
the detectable target (screw, pin or small raised area on the rotating disc)
at .010"-.060" with a brass
feeler gauge. And being 3-wire inductive
proximity sensors have a farther detection range, set the air gap/clearance
of .010"-.188". If the gap is wider than .188" (3/16") with either sensor,
the ignition system may not produce a spark or the engine may misfire at
higher RPM. And to prevent the possibility of an out of time spark, the
detectable target needs to be a minimum of 3/16" higher than or above the
circumference surface of the rough casting on a steel disc or cast iron flywheel.
Direct metal contact with either sensor could damage them! When
in doubt if a sensor is mechanically damaged, look at the end of it with
the strong magnifying glass to see any damage. If it is damaged, it needs
to be replaced. A magnetic pickup coil can be tested with a digital
multimeter set on 200m DC, with the negative lead of the meter on the white
wire of the pickup coil and positive lead on the black wire, then pass a
small steel screw or bolt over the end of the magnetic pickup coil. If the
meter shows a reading, the pickup coil is in good condition.
Magnetic Pickup Coils
for A-1 Miller's custom-made flywheel-
or crank-trigger electronic ignition
systems. All magnetic pickup coils are Normally Open, and isolated from the
mounting bracket, so a steel bracket can be used. Either can be used with
the high-output/performance GM 4-pin HEI module w/1.0 ohm coil, or with the
Chrysler or Ford electronic ignition control module/units. Self-generating
power. Detects head of small ferrous metal (steel) screw or bolt fastened
to rotating disc or flywheel to generate electricity in the magnetic pickup
coil. Install screw head extended minimum 3/16" higher than or above the
surface of the [cast iron or steel] flywheel to prevent an out of time spark
occurrence by the flywheel itself. Wide operating temperature range.
epoxy-encapsulated, mechanically rugged. Impervious to dirt, oil and water.

Please specify size when ordering. Can be used with a steel bracket without
interference of magnetism. By the way - The magnetic pickup coils below work
exactly the same. There is absolutely no difference in performance.
Set the air gap/clearance from the detectable target (screw, pin or small
raised area on the rotating disc) at .010"-.020" with a
brass
feeler gauge.

incorrectly, the LED will stay on and go off when activated.
PNP = Positive/Neutral/Positive. NPN = Neutral/Positive/Neutral.
Positive is when connection is made. Neutral is when connection is not made.
NOTE: Set air gap/clearance at .010" - .188". Direct metal contact
with either sensor will damage them. And if the gap is wider than specified,
the engine could misfire at higher RPM. To prevent the possibility of an
out of time spark, the detectable target needs to be a minimum of 3/16" higher
than or above the circumference surface of a steel or cast iron rotating
disc or flywheel.

High Quality, Reliable and
Durable Digital Tachometer/Proximity Sensor Kits. A tachometer is required
in setting the correct engine RPM, which is normally 3,200 or 3,600 RPM
(depending on type of carburetor), to prevent from over-revving and possible
damage to the engine or dangerous flywheel explosion. Choice of a
RED or
BLUE numeric display. Will work with
most small engines or multi-cylinder automotive engines, gas or diesel. Very
accurate, vibration-proof and weatherproof construction. The great thing
about this type of tachometer is that it needs no setup or programming. Displays
accurate RPM as soon as the engine cranks over to start. Displays up to 9,999
RPM. Tachometer returns to zero [0000] when engine is shut down. Can be used
for lawn & garden equipment or competition pulling engines. Designed
to be permanently mounted to monitor engine RPM at all times. Tachometer
can be in-dash or panel-mounted. This precision digital tachometer operates
with external power and on the same principle as my
flywheel- or
crank-trigger ignition systems with a proximity sensor to detect the
target, which can be a small ferrous steel screw or pin, or magnet in a rotating
disc on the crankshaft or on/in flywheel. Operates totally independent of
the ignition system, or can be used with crank trigger ignition with the
same proximity sensor. Sensor is capable of powering this digital tachometer
and crank-trigger ignition module at the same time, with the exception of
using the electronic ignition modules. This tachometer must be wired separately
or wiring can be incorporated with my crank-trigger ignition system that
use a proximity sensor. A sturdy metal bracket will need to be fabricated
by customer to mount the sensor in close proximity of the detector/trigger
target. Set air gap/clearance at .010"-.188". Tachometer works with 8-24
volts DC, proximity sensor works with 6-36 volts DC. Dimensions for mounting
hole for tachometer: 3" wide x 1-17/32" wide. Tachometer measures 1" in depth.
Dimensions of proximity sensor: 15/32" diameter threads x 1-3/8" thread length.
Wiring Instructions: #1 wire on tachometer connects to
BROWN wire on proximity sensor and ignition
switch (12 volt power), #2 wire on tachometer connects to
BLUE wire on proximity sensor and
engine/chassis ground (which connects to the negative (–) battery post),
and #5 wire on tachometer connects to BLACK wire on either proximity
sensor listed below. Wires #3 and #4 connects to nothing. Wiring is the same
for the hall effect and inductive proximity sensors. Certain proximity sensors
have an LED (Light Emitting Diode), which flashes when in close proximity
of target. If the proximity sensor is wired incorrectly, the LED will illuminate
at all times.

removed
the new armature/stator assembly and reinstalled the original armature/stator
assembly; installed a new OEM Kohler magneto armature ignition coil on the
armature; and even tried a different flywheel, but with all of these things,
one after the other, the engine would still die out above idle, no matter
what. Then I connected a temporary battery-powered ignition system with jumper
wires with alligator clips just to find if the engine would rev up at open
throttle, and it did, with no problems! Then after all of this, I found that
the charging system would not generate the full 10 amps to recharge the battery.
It would only generate about 3 amps. (The tractor had a factory-installed
amp gauge.) The voltage rectifier/regulator was in good condition too, but
there was nothing I could do to fix this.
Fasten the module to the engine
sheet metal that has plenty of cool, circulating air with the supplied mounting
screw.

Solid State Ignition Module as shown to the right ->. Fits Tecumseh engine
blocks with two bosses with the 2-13/16" bolt hole spacing for the OEM SSI
module. This will NOT work on a Tecumseh engine with a starter/generator
because there are no protruding pins on the edge of the flywheel to trigger
the spark. This replacement ignition system installs in place of the
OEM Tecumseh Solid State Ignition (SSI) module unit and is completely
hidden under the flywheel shroud, with no external ignition components
exposed, with only one wire connection to the ignition switch. Works
great for lawn & garden, and generator/welder engines! This ignition
system works flawlessly and may outlast the life of the engine. This
