Prices are subject to change without notice. FYI - All aftermarket parts that is offered in this website are of very high quality and come with an unconditional guarantee. As a matter of fact, the aftermarket parts are just as good or better quality than most OEM Kohler parts.
FYI - Being nobody have ever brought a single- or two-cylinder Onan or Wisconsin engine to my shop for repairs, I have no experience with working on them. Apparently, these engines must be rare in my area (mid-Missouri). Otherwise, I would offer custom-made electronic ignition conversion kits for these engines, too. - Brian Miller |

Conventional (Points and Condenser) Ignition Parts -
 Ignition
Points for Kohler, Tecumseh and Clinton engines. Fits Kohler engine models
K90/K91, K141, K161/K160, K181, K241, K301, K321, K330/K331, K341, K361,
KT17 (first design), KT17 Series II, KT19 (first design) KT19 Series II,
K482, K532 and K582 with magneto or battery ignition (use with mounting bracket).
Also fits Tecumseh cast iron block engine models HH80, HH100, HH120 with
magneto or 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 battery-powered
points/condenser ignition. NOTE: Virtually any magneto point ignition
system can be converted to a more reliable solid state ignition with the
universal electronic transistorized ignition
module that I offer, or if possible, upgrade/convert the engine with
my reliable custom-made battery-powered
flywheel-trigger electronic ignition
for a better running engine.
  Hex Socket (Allen) Head Cap Screw w/split lock washer.
Fits Ignition Points on single cylinder Kohler and cast iron block Tecumseh
engines. Replaces Phillips or OEM slotted head adjustment screw in points.
This stainless steel Allen head screw makes it much easier to precisely set
the point gap and/or ignition timing with a 9/64" hex (Allen) L-wrench than
the OEM slotted or Phillips screw with a straight or Phillips screwdriver
so the points will not slip out of adjustment in garden tractors 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. No need to use this for garden tractors with
a
transverse engine, such as older Bolens, belt-drive John
Deere, Massey Ferguson, Sears Suburban, Wheel Horse, etc. NOTE: The threads
for the adjustment screw in aftermarket points may need to be rethreaded
with a 8-32 UNF [preferably]
TAPER hand tap.
And due to risk of stripping threads in the thin metal points bracket, do
not over-tighten this adjustment screw! An ingenious and innovative
concept by Brian Miller. Please accept no advertised copycat products of
this kind. (But I do appreciate them acknowledging my ingenuity and
intelligence.) 
Chevy Points Bracket and Cover w/all mounting hardware (screws). Use on Kohler K-series competition pulling engines. Professionally CNC machined of thick aluminum to minimize timing fluctuations. $40.00, plus shipping & handling. TIP: When installing small Phillips- or slotted-head screws, to prevent them from falling out of the screwdriver tip and into a hard to reach place, 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. |

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.)

| NOTE: If an engine idles well, but runs erratically when
revved up, like it hits and misses, pops and backfires, then chances are,
it needs a new condenser/capacitor. And always install a condenser/capacitor
with the wire facing downward so rain water and/or when washing off engine,
water will not enter inside condenser/capacitor, ruining it. With water inside
the condenser, this will also allow it to idle well, but cause it to run
erratically when revved up.
Click/tap here to hear what an
engine with a faulty condenser/capacitor sounds like. And virtually
any magneto point ignition system can be converted to a more reliable solid
state ignition with the universal electronic
transistorized ignition module that I offer, or if possible, upgrade/convert
the engine with my reliable custom-made battery-powered
flywheel-trigger electronic ignition
for a better running engine.

  Grounding-Type Safety Break-Away / 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 solid state electronic 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 electronic
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. The electric
fuel pump must be shut-off manually by the ignition switch or an OFF-ON
toggle/flip switch or [security] key switch.

 Armature
Ignition Coil with Integrated Solid State Electronic Integrated Module.
Fits Kohler Magnum engine model M8. NOTE: Install 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
at .010" with a paper or brass feeler gauge. The .010" gap produces a stronger
magnetic field through the coil to generate more power for a stronger spark,
and so the engine won't misfire. And use a new Autolite or Champion copper
core/non-resistor spark plug of the correct type gapped at .025" for longer
coil life.

 Armature Ignition
Coil with Integrated Solid State Electronic Integrated Magnetron™ Module.
Fits Briggs and Stratton horizontal and vertical shaft opposed twin cylinder
engines. NOTE: Install 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 at .010" with a paper or brass feeler
gauge. The .010" gap produces a stronger magnetic field through the coil
to generate more power for a stronger spark, and so the engine won't misfire.
And use a new Autolite or Champion copper core/non-resistor spark plugs of
the correct type gapped at .015" each for longer coil life.

To test for the
continually of an ignition coil (to see if it's in good condition), use a
multimeter set on the Ohm ( ) resistance. Insert
one of the multimeter's probes into the spark plug terminal of the coil,
contacting the metal inside the terminal. Touch the second probe of the meter
to the ignition coil's negative (–) terminal. (This is the one not connected
to the primary resistor.) Depending on the type of coil (magneto, small size,
standard size or high output/performance), the meter should read 6,000 to
15,000 ohms. If it does not, the coil's secondary winding is
faulty. |

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/flip 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.

 New
1.6 ohm Ballast Resistor for use with a 12 volt ignition coil not
having an internal resistor (listed above) to prevent excessive burning of
points contacts, or use with the Chrysler / Dodge / Plymouth electronic ignition
control module/unit, or connect with coil having a minimum 1.4 ohm internal
primary resistor to prevent burning up the
DynaTek Dyna S electronic ignition control
modules. Install between the coil positive [+] terminal and wire coming from
the ignition switch to the coil. This will allow the points to possibly last
the life of the engine. NOTE: Ignition resistors with a higher
ohm value are known
as "Point Savers." The higher the ohm resistance in an ignition coil or a
ballast resistor has, the longer the ignition points will last (as long as
the points are installed clean, and doesn't become contaminated with dust,
oil, water, etc.). Any 12 volt ignition coil with an 3+ ohm internal primary
resistor connected to a minimum 1.6 ohm ballast resistor when used in a points
and condenser/capacitor ignition system will allow the points to possibly
last the life of the engine. Because the increased resistance allows a very
low current/voltage to pass through the contacts in the points. Also, a
suppression/carbon-core coil-to-spark plug wire and resistor type spark plug
shouldn't be used in this system due to overheating of the ignition coil.
Therefore, it's best that a high temperature metal core conductor coil-to-spark
plug wire and copper core/non-resistor spark plug be used. The ignition system
will still produce a strong spark because an average small engine requires
only a fraction of voltage from the coil. This is best to used with general
lawn and garden, snow removal, etc., and not for competitive pulling. Therefore,
if it's not already equipped, it's best to install an
ammeter/amp gauge to monitor the charging
system. $8.00 each, plus shipping & handling. |

engine models K141, K160/K161, K181, K241, K301, K321, K330/K331, K341, K361,
KT17 (first design), KT17 Series II, KT19 (first design) KT19 Series II,
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 at all times! Copper or metal wire delivers
maximum energy with zero ohm resistance to the spark plug, which allows the
ignition coil to operate cooler and last longer. (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 wide open throttle engine operation.) Solid brass 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 boot for a 5/8"
(fits most dual wire twin cylinder coils and high-output/performance coils)
or 3/4" (fits most standard-output coils) diameter coil
tower.

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
a charging system integrated with the engine to recharge the battery is the
use of a remote battery charger. And eventually a new battery will need to
be purchased, because they only last a few years. 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 (cast iron engine) Solid State Ignition (SSI) systems use a [security] key switch that's also made for a self-energizing magneto or magneto-type solid state 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/flip switch or [security] key switch to power the ignition and a momentary push button 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. |

 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 magneto ignition
and a 10 amp alternator charging system. (The ignition coil and charging
coils are on the same armature/stator plate 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 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 magneto ignition/charging system 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.)
Anyway, I decided (actually, I had no choice because I'm so determined) to
convert the engine to the more reliable battery-powered ignition system.
But being this JD 110 has a confined engine compartment with limited space
and with the air cleaner assembly that fastens directly to the carburetor
with no upward intake elbow, there is no place to mount a full size 12 volt
canister ignition coil. So I fastened a new compact
epoxy-encapsulated 12 volt armature ignition coil on the carburetor side
of the flywheel shroud. I removed the shroud, located where to drill two
7/32" holes to mount the coil, and although
Rivet Nuts could have been used, I just
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 magneto ignition to battery-powered ignition for your tractor. See the complete ignition conversion kit(s) below. I can also convert your tractor from a faulty magneto ignition to the more reliable battery-powered ignition if you don't mind bringing your tractor to my shop. - Brian Miller Click here to contact A-1 Miller's for FREE honest and accurate technical support and/or for ordering information and payment options.

Convert virtually any single cylinder, air-cooled cast iron or various aluminum block small gas engine, such as Kohler, Tecumseh, Briggs & Stratton, Clinton, etc., with a failed magneto ignition system to the battery-powered ignition system. NOTE: Must use a universal automotive off/ignition/start key switch, or a push-button switch to crank the engine with an OFF-ON toggle/flip switch or [security] key switch to power this ignition. Reuse same type of spark plug and existing ignition points (if in good condition), but set the point gap at .020" or set ignition timing at 20º BTDC. See ignition kits and wiring diagram below Ê.
High Quality Ignition Kit to Convert from Kohler Magneto Ignition to the
More Reliable Battery-Powered Ignition System for a Confined Engine
Compartment with Limited Space and no place to mount a full size canister
coil. A fully charged 12 volt battery is required for this ignition
system. Designed for Kohler engine models K90/K91, K141, K161/K160, K181,
K241, K301, K321, K330/K331 and K341. When ordering, please indicate model

"assemble-it-yourself" #16 gauge (AWG) coil-to-points wire w/terminals (reuse
original points cover/wire grommet); and new spark plug. To install terminal
on spark plug wire, make sure the pointed prong on the terminal penetrates
the insulation of the wire, or strip a short part of the insulation and bend
over the wire to make full connect with the terminal, and use a
spark plug wire crimping tool, then apply automotive grease
on the spark plug wire and inside boot so it will slide easily on the wire
and over the terminal. And if using this kit on an engine with a recoil
starter, as for the battery cables, being I have no idea how long they need
to be, you will need to fabricate these yourself. When ordering, please specify
model of engine for correct type of spark plug. Dimensions of coil - overall

High Quality Ignition Kit to Convert from Kohler Magneto Ignition to the More Reliable Battery-Powered Ignition System for an Unconfined Engine Compartment with Unlimited Space to mount a full size canister coil. A fully charged 12 volt battery is required for this ignition system. Designed for Kohler engine models K90/K91, K141, K161/K160, K181, K241, K301, K321, K330/K331 and K341. When ordering, please indicate model of engine. New parts include: full size 12 volt canister ignition coil w/3.0 ohm internal primary resistor and mounting bracket, 11" length metal core conductor spark plug wire, medium capacity condenser/capacitor, ignition points, points cover gasket, 12" length "assemble-it-yourself" #16 gauge (AWG) coil-to-points wire w/terminals (reuse original points cover/wire grommet), and new spark plug (please specify model of engine when ordering for correct type of spark plug). Set spark plug gap at .035" with this system. And if using this kit on an engine with a recoil starter, as for the battery cables, being I have no idea how long they need to be, you will need to fabricate these yourself. IMPORTANT - Either an OFF-ON-START battery-powered rotary ignition key switch or an OFF-ON toggle/flip ignition switch or an OFF-ON key ignition switch (for security purposes) and a momentary push button switch (to crank the engine if it is equipped with an electric starter) MUST be used with this type of ignition system. Go here for choice of switches. And the original magneto coil can be removed from the stator. It will not be needed. If the stator has charging coils, leave them installed and connected so they can recharge the battery and power electrical accessories. IMPORTANT - All coils 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/flip switch to power the ignition system.

FYI - I can install any of my custom-made flywheel- or crank-trigger electronic ignition systems on your older small gas engine and/or rewire your lawn & garden tractor, equipment or competition garden pulling tractor so all the electrical accessories will work and if everything else is in good condition with the engine (compression, carburetion, etc.), the engine should start quickly, idle well and rev up to its full potential every time. I have the knowledge, skills, all the tools and parts necessary to perform a professional job. I've rewired many customer's lawn & garden tractors, small engine equipment and competition garden pulling tractors many times with great results. If you're interested, click/tap here for my contact information and directions to A-1 Miller's shop. - Brian Miller
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 conductor 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-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.
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 power. 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 power. 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 (partially burned diesel fuel ash). 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 power 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-trigger electronic ignition is the way to go! The high performance electronic ignition systems offered in this website produce a stable and very strong spark with the use of microelectronics. They will allow the engine to start quicker, idle smoothly, rev up to full RPM with no hesitation or misfire and produce more power.
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-trigger 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/flip switch or [security] key switch to power the ignition and a momentary push button 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.

If a Kohler flywheel has no projection (hump) or large bolt head for Breakerless Ignition, but does have a 3/4" wide area between the fins and ring gear (as shown in the photos above È), 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-trigger 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 magnetic pickup coil or 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 proximity 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 hall effect PerTronix Ignitor module/sensor, 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 or 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. An original, ingenious, thoroughly
researched and innovative concept invented by Brian Miller, because nobody
else advertise this for use on a small engine. Please accept no advertised
copycat products of this kind. (But I do appreciate them acknowledging my
ingenuity and intelligence.)
Information About Converting from Kohler's [Failed] Breakerless Ignition to a Custom-Made Electronic Ignition System or a Battery-Powered Points/Condenser Ignition System | [Top of Page]
The wire that connects from the stator to the
Kohler Breakerless Ignition Trigger Module or Tecumseh Solid State Ignition
Module generates about 250 volts (seriously) while the engine is running
at full governed speed. (Seriously; I tested it with a voltmeter.) Do not
touch this wire/terminal with one bare hand and the engine itself with your
other hand while the engine is running! Electrical shock or electrocution
could result. This wire is not required with any of A-1 Miller's custom-made
flywheel-trigger electronic ignition systems. So snip off this wire or tape
up the terminal.
There is a tiny brass cup/expansion plug in the points pushrod hole. This plug MUST be removed for using the pushrod when converting to points ignition. To prevent damage to certain moving parts inside the engine and possible eventual engine failure, do not punch this plug into the crankcase! It may NOT drain out with the oil when the oil is changed. To remove this plug, carefully and gently drill a 3/32" 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 Vise-Grips or a small crowbar or pry bar to pull the plug out of the hole. Because the self-tapping drywall screw by itself may not be able to bore a hole through the plug without pushing it deeper into the drilled hole. And do not force the drill bit into the plug or it could fall inside the crankcase! And a 3/16" drill bit or hand reamer may need to be used to clean out any debris from the pushrod hole. After the points is 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 reuse the same type of spark plug gapped at .035".
Custom-Made Electronic Ignition Kits (below) for Converting to Flywheel-Trigger Ignition for Kohler engine models K241, K301, K321, K341, K361 that came with points/condenser ignition or with 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-trigger ignition! NOTE: Engine must have the large bearing plate with two mounting bosses to install the triggering device and 9" flywheel with 3/4" wide area with the projection (hump) or large bolt head, or install a small screw/bolt (so the sensor can detect it). Must also use an OFF-ON toggle/flip switch or an OFF-ON key switch (for security purposes; for ignition) and momentary push-button switch (to crank the engine) for ignition system below Ê. With this ignition setup, the ignition timing will be set at 20º BTDC, and reuse same type of spark plug, but set gap at .035" for a stronger spark.
 
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/flip switch to power the ignition system.

IMPORTANT - Due to length of spark plug wire, please indicate if original coil is mounted next to carburetor (10" length) or above starter gear (13" length). Set spark plug gap at .035" with this system. NOTE - Being this ignition system requires 12 volts DC negative ground, 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 power source (battery). So with this ignition system, you will need either an OFF-ON-START battery-powered ignition key switch, or an OFF-ON toggle switch or an OFF-ON key switch (for security purposes; to power the ignition) and a momentary push button switch (to crank the engine). 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/flip 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.

3/16" Steel Plug to Replace Kohler Ignition Points
Pushrod. Use in Kohler engine models K90/K91, K141, K160/K161, K181,
K241, K301, K321, K341, K361, K482, K532 and K582 when converting from magneto
to solid state ignition (listed above), Magnum solid state ignition, A-1
Miller's flywheel- or
crank-trigger electronic ignition (further
down in this website). Remove the points cover, ignition points and pushrod,
and install this plug in the pushrod hole (to prevent major oil leakage)
with a medium size hammer; fits very tight. 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 knurling will retain the
pushrod in the hole. An ingenious and innovative concept by Brian Miller.
Please accept no advertised copycat products of this kind. (But I do appreciate
them acknowledging my ingenuity and intelligence.)

I offer these custom-made electronic ignition kit options:
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 flip the ignition toggle switch on, and the engine would start every time without hesitation. This is because the engine have a fixed and set in the fully advanced ignition timing position with no retard, and is (obviously) high compression. Starting the engine this way prevents it from kicking back, and it prevents damage to the aluminum starter motor housing. - Brian Miller 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. - Brian Miller (Posted 8/24/20) |

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 DynaTek Dyna S module/sensor produce a stable and very strong spark with the use of microelectronics. They will allow the engine to start quicker, idle smoothly, rev up to full RPM with no hesitation or misfire and produce more power.
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 module/sensor 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, the DynaTek Dyna S or PerTronix Ignitor modules provides 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 module/sensor. These sensors/modules packs a lot of punch and allows 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 module/sensor 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 module/sensor might fail prematurely. A metal conductor spark plug wire and copper core/non-resistor spark plug should be used. If the voltage drops below the minimum requirement for either module/sensor, the engine may idle well, but not rev up, or the engine may run erratic. Either module/sensor can be used with a standard-output/stock or high-output/performance 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.
DynaTek Dyna S Maintenance-Free Crank-Trigger Electronic Ignition Installation Instructions -
A-1 Miller's universal flat aluminum mounting plate with the
DynaTek Dyna S ignition module/sensor 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 module/sensor. Air gap/clearance between the
module/sensor and locking set screw collar w/embedded magnet is .010"-.050".
Module/sensor may not operate or engine may misfire if gap is wider than
.060". NOTE: Do not allow module/sensor to make
contact with locking set screw collar w/embedded magnet while engine is
running! Click

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"-.050". 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 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/flip switch to power the ignition system.

How to Check for Spark and Set the Timing for the DynaTek Dyna S (or PerTronix Ignitor) module/sensors - After either setup is installed on the engine and power 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 module/sensor, 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 module/sensor -
How to accurately set the ignition timing STATICALLY for the DynaTek Dyna S, PerTronix Ignitor and Inductive 3-Wire Proximity module/sensor - (This is also how to test if the module/sensors 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 module/sensor. (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 module/sensor 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, plastic, business card,
poster board, stainless steel (anything non-magnetic) feeler gauge. And being
3-wire inductive proximity sensors have a farther
detection range, set the air gap/clearance at .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 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. 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

crank-trigger electronic ignition. All
magnetic pickup coils are Normally Open. Either can be used with the
high-output/performance GM 4-pin HEI module w/1.0 ohm coil, or with the Chrysler

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.

Now the ordinary/stock GM 4-pin HEI electronic ignition control
module lives up to its name, High Energy Ignition! When used on a small engine,
in order for an ordinary/stock GM 4-pin HEI module allow the engine rev up
to full RPM, it must be used with the high output cube-shaped 3-wire inductive
proximity sensor, and can be used with virtually any ignition coil,
regardless of the ohm resistance or voltage output. A metal core conductor
coil-to-spark plug wire and copper core/non-resistor spark plug should be
used to guarantee a stronger spark. Use an ohm meter to test for the resistance
in a spark plug wire. Set spark plug gap at .035". Sensor is capable of powering
the GM 4-pin HEI crank-trigger ignition control module and a digital
tachometer at the same time. This concept
revolutionizes the use of this small, compact and versatile module! This
is a thoroughly tested, researched and proven reliable ignition system invented
by Brian Miller for ordinary lawn and garden engines and competition pulling
engines. And when mounting the HEI module, always fasten it with
thermal paste (to dissipate normal operating
heat) on a clean, flat aluminum plate with plenty of cool, circulating air
to dissipate the heat while in operation.

IMPORTANT - The wire that comes from the stator
under the flywheel for Kohler Trigger Module or Tecumseh Solid State Electronic
Ignition Module generates about 250 volts (serious) while the engine is running
at full governed speed. Do not touch this wire (terminal) with one bare hand
and the engine itself with your other hand while the engine is running! 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 to prevent a short circuit or
electrocution. [Return

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 control module at the same time, with the exception
of using the Dynatek Dyna S or PerTronix Ignitor 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 steel or aluminum 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 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. Wires #3 and #4 connects
to nothing. Wiring is the same for the hall effect and inductive proximity
sensors. Some proximity sensors have an LED (Light Emitting Diode) on the
rear of unit. If the proximity sensor is wired incorrectly, the LED will
illuminate within the target.

removed
the new stator assembly and reinstalled the original stator assembly; installed
a new OEM Kohler magneto armature ignition coil on the stator; 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 just to find
if the engine would rev up to full 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. But not all JD 110's have this problem. Only a few of them.

and Maintenance-Free Replacement Electronic Ignition Kit for Tecumseh engine
models VH80, VH100, HH80, HH100, HH120, OH120, OH140, OH150, OH160 and OH180
with a gear starter that have a failed OEM Solid State Ignition Module
as shown to the right. 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. Works great for lawn & garden, and
generator/welder engines! This ignition system works flawlessly and may outlast
the life of the engine. 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 from outside view, with only one wire
connection. This high performance ignition system have been thoroughly tested
under extreme conditions, and produces a stable and very strong spark with
