 High Quality
Digital Tachometer/Proximity Sensor Kits. A tachometer is required in
setting the correct RPMs (normally 3,200 or 3,600 maximum for small engines)
of an engine 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
single- or twin-cylinder small engines or multi-cylinder automotive engines,
gas or diesel. The great thing about this type of tachometer is it needs
no setup. It displays accurate RPMs as soon as the engine cranks over to
start. Displays up to 9,999 RPM. Very accurate. Tachometer returns to zero
[0000] when engine is shut down. Operates totally independent of the ignition
system. 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. 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 (battery
negative (–) 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.
Click or tap here for YouTube videos to see how well this
tachometer works. Cannot be wired in conjunction with the Dynatek Dyna
S or PerTronix Ignitor ignition modules. This tachometer must be wired separately
or wiring can be incorporated with my crank-trigger ignition system that
use a proximity sensor.

  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 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.

  Superior Quality, High Velocity 12 Volt Engine Cooling Fan.
Use an electric fan to cool a competition garden tractor pulling engine with
a steel flywheel. Motor is 100% secured and reinforced in plastic fan housing
tube to withstand severe engine vibrations, and to prevent motor from loosening
and become inoperable due to normal engine vibrations when pulling. Modification
made by Brian Miller. No need to mount fan housing on rubber grommets; they
will serve no purpose whatsoever with this fan. Fasten fan housing on a sturdy
angle steel support brace with 1/4" bolts, lock washers and wide, flat washers
in front of engine or behind grille in a Cub Cadet garden tractor aimed at
the exhaust area of engine. Draws 2.6 amps, produces 145 CFM. Measures 3"
diameter and 5" length. IMPORTANT! Due to normal
engine vibrations, do not run fan while pulling because the brushes that
make contact with the commutator could break! If tuned correctly and the
carburetor air/fuel mixture is set correctly, the engine should not severely
overheat during the 2-3 minutes of pulling down the track. Turn fan on ONLY
between pull-offs or when tuning engine or adjusting
carburetor. $35.00 each, plus shipping & handling.

 High Torque
Gear Starter Motors for Kohler engine models K141, K161 and K181 single cylinder
cast iron block Kohler engine. 12 volt, 16 tooth gear. All starter motors
are high torque nowadays. They have 20% more wire windings than the early
OEM Kohler starter, giving it 20% more cranking power. Draws less amps; a
smaller battery can be used. Cranks engine about twice as fast and draws
less amps than an ordinary starter.
But with a
broken compression release, a direct-drive high torque starter may not be
able to crank the engine. It'll be best to adjust the valve clearances, repair
the compression release mechanism or replace the cam with a working compression
release. FYI - The aftermarket starter motors I
sell are the same as OEM Kohler starters. Kohler just place a big markup
on theirs because it comes in a Kohler brand box and the starter has the
Kohler name stamped on it. Kohler part # 41 098 08-S.

Motors for Kohler K-series engine models K241, K301, K321, K341 and K361.
12 volt. All new starter motors are high torque nowadays. They have 20% more
wire windings than the early OEM Kohler starter, giving it 20% more cranking
power. Cranks engine about twice as fast and draws less amps than an ordinary
starter. Therefore, a smaller battery can be used. In addition to the extra
windings, the 10 tooth starter gear gives this starter extra torque so it'll
crank the engine with less effort. The 10 tooth starter provides 13% more
cranking torque than the 13 tooth starter, and the 13 tooth starter cranks
the engine over 30% faster than the 10 tooth starter. The 13 tooth starter
is best to be used with working compression release.
But with a
broken compression release, a direct-drive high torque starter may not be
able to crank the engine. It'll be best to adjust the valve clearances, repair
the compression release mechanism or replace the cam with a working compression
release. FYI - The 10 tooth starter cannot be used
in place of the 13 tooth starter, but the 13 tooth starter can be used in
place of the 10 tooth starter by shimming/spacing the starter away from the
engine block with an ordinary flat washer on each mounting
bolt.
And the aftermarket starter motors I sell are the same as
OEM Kohler starters. Kohler just place a big markup on theirs because it
comes in a box with the Kohler name on it and the starter has the Kohler
name stamped on it.

 Universal
Analog 10 Amp and 20 Amp Ammeter / Amp Gauge Kits. Gauges registers up
to 10 or 20 amps of charge, depending on total output amperage of stator
or alternator. Install these gauges to know exactly what the charging system
on your engine is doing. Having an ammeter/amp gauge installed is very important
in monitoring the charging system to prevent premature failure of electrical
components. By the time you smell something burning or see smoke, it may
be too late. If the charging system continues to charge on the plus (+) side
with no gradual moving back of the needle to zero on the gauge (if installed)
while the engine is running at full governed speed, this will send too much
voltage to the battery, which could eventually burn up the cells in the battery,
or burn up the primary windings in the ignition coil. Overcharging of the
electrical system could also burn up the electronic ignition control module/unit
(crank-trigger and flywheel-trigger), burn
out light bulbs, electric PTO clutch or any other electrical accessories.
As battery becomes fully charged, needle slowly moves from positive side
(+) to zero (0). Needle will stay on negative side (–) if no charge
goes to the battery. Or gauge will not show any charge at all if charging
system is not working. Easy 2-wire connections. Connect the positive (+)
terminal on back of gauge to the battery positive (+) post, and connect the
negative (–) terminal on back of gauge to the wire going to the ignition
switch that provides power to everything. If the
wires/connections are reversed, and if the charging system is in good working
condition, the gauge will show discharge (–) instead of charge (+).

 New 12 volt,
15 Amp Analog Voltage Regulator for Starter/Generators. If the charging system
continues to charge with no gradual moving back of the needle to zero on
an analog ammeter/amp gauge (if installed) while the
engine is running, this will put too much voltage through the coil, eventually
burning out the primary windings. Overcharging of the charging system could
also burn up the electronic ignition control module
(crank trigger), burn up the battery, burn
out light bulbs, electric PTO clutch and any other electrical accessories.
With the terminals facing you, they read: L (Lights) | Bat (Battery) | F
(Field), with A (Armature) on the bottom. L connects to the Lights (if equipped);
Bat connects to the ignition switch, which connects to the positive (+) post
on the battery; F connects to the Field terminal on the starter/generator;
and Armature connects to the Armature terminal on the starter/generator.
The frame of the regulator must be securely grounded to the tractor or equipment
through the mounting bolts. NOTE: Cannot be substituted for use with
the alternator/stator charging system.

   Two Wire Rectifier
Diodes. The 3- and 4-amp diodes can be used in a non-regulated small engine
alternator/stator12 volt charging system to convert alternating current (AC)
to direct current (DC) to recharge the battery and/or to power low-amperage
DC electrical accessories, such as LED lights, small electric motors, etc.
A diode is not required for
filament light bulbs, fluorescent and LED shop lights,
and/or an electric PTO clutch. Do not overload the amperage of the diode
or it may burn up. The 1 amp diode can be used on an engine with a small
charging coil next to the magneto ignition coil on the stator to energize
the field windings in a direct-drive 120/240 volt AC portable generator powered
by a small engine or for a
belt-driven automotive
alternator that's powered by a small engine so the alternator/generator
will produce electricity as soon as the engine starts. IMPORTANT - Install
the diode with the silver stripe toward the generator's field windings.
FYI - Briggs & Stratton engines have either one or two OEM alternator stators and they are joined together in two half circles under the flywheel. Some engines only come with one half stator. Each half produce 3 amps of power & 14 volts @ 3,600 RPM. If an engine comes with two stators joined together, one half produces AC, which is used to power the lights and electric PTO clutch. And the other half also produce AC, but is connected to a minimum 3 amp/14 volt diode, which is used to only recharge the battery. Under normal yard use, 3 amps is not enough to overcharge and burn up the battery. If both stator halves are wired together from the factory (as they are on certain engines), they will produce 6 amps of AC power and a 6 amp solid state electronic voltage rectifier/regulator is used to power the lights, electric PTO clutch and recharge the battery. |

 Voltage
Rectifier/Regulators for New-Style 15/20 Amp 12 Volt Alternator/Stator Charging
Stators below. If the charging system continues to generate full charge with
no gradual moving back of the needle to zero on an analog
ammeter/amp gauge (if installed) while the engine
is running, the excessive overcharging may eventually burn out the primary
windings in the ignition coil, burn up the electronic ignition control module
(crank trigger), burn up the battery, burn
out light bulbs, electric PTO clutch, and any other electrical accessories.
The solid state electronic voltage rectifier/regulators shown works the same.
These voltage rectifier/regulators are small, compact and have the same mounting
hole spacing, and fit many 8 thru 24hp Kohler engine models with a 15 amp
or 20 amp output alternator/stator charging stator under the flywheel. Each
mounts in the rectangular hole in the Kohler flywheel shroud with ribs facing
the flywheel for better cooling of the unit. If it's mounted elsewhere with
no cool air blowing over it, it could burn up prematurely. These will also
work with virtually any 15 or 20 amp garden tractor, motorcycle,
etc.alternator/stator charging system. Orientation of the terminals are "three
in a row" (AC - BAT+ - AC). NOTE: These cannot be substituted for use
with the starter/generator charging system.

 Solid State Electronic
Voltage Rectifier/Regulator for Old-Style 10 Amp 12 Volt Alternator/Stator
Charging Stators below Ê. If the charging
system continues to generate full charge with no gradual moving back of the
needle to zero on an analog ammeter/amp gauge (if
installed) while the engine is running, the excessive overcharging may eventually
burn out the primary windings in the ignition coil, burn up the electronic
ignition control module (crank trigger), burn
up the battery, burn out light bulbs, electric PTO clutch, and any other
electrical accessories. These will also work with virtually any 15 or 20
amp small engine alternator/stator charging system. Orientation of the terminals
are "three in a row" (AC | BAT+ | AC). NOTE: Cannot be substituted for
use with the starter/generator charging system. FYI: After many years
of use and for reasons unknown (even to me), the old-style 10 amp charging
system is notorious for generating very few amps, about 3 amps more or less
maximum at full governed engine speed, and I have no idea why. I believe
this is why the 10 amp stator was a short-lived item that was discontinued
from Kohler and replaced with the more reliable 15/20 amp stator charging
system, which works much better and is still in use on many makes and models
of small engines today. So if your engine has the 10 amp charging system
and it only generates a few amps, it may need to be upgraded with the new-style
15/20 charging system.

Dimensions: 4-5/8" O.D. x 2-3/4" I.D. x 2-1/4" bolt pattern. Discontinued
OEM Kohler part # 237065-S; John Deere part #'s AM32073, AM32334 (w/o solid
state electronic ignition); replaces Tecumseh part # 610761A (w/o solid state

 Old-Style 10 Amp 12 Volt Alternator Charging Stator w/Electronic
Ignition Energizing Coil. Can be used with Kohler Breakerless, Tecumseh Solid
State, or Points/Condenser Ignition. This stator requires a flywheel with
charging magnets embedded in an aluminum ring. Use with 10 amp solid state
electronic voltage rectifier/regulator (above) to recharge battery while
powering electrical accessories. To be used with a Kohler or Tecumseh flywheel
designed for a John Deere garden tractor. Fits John Deere garden tractors
with a cast iron block Tecumseh engine model VH80, VH100, HH80, HH100, HH120,
OH140, OH150, OH160 and OH180 with solid state ignition, and used on Kohler
engine models K241 w/specification #'s 46593 and 46608; K301 w/specification
#'s 47148, 47175, 47399 and 47419; K321 w/specification #'s 60102, 60118,
60136 and 60136A with Breakerless Ignition. Dimensions: 4-5/8" O.D. x 2-3/4"
I.D. x 2-1/4" bolt pattern. OEM Kohler part # 237877-S; OEM Tecumseh part
# 610761A; John Deere part # AM31738.
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; I tested it) 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 battery ignition or any of my crank trigger
ignition systems. So snip off this wire or tape up the terminal to prevent
a short circuit or electrocution! FYI: After many years
of use and for reasons unknown (even to me), the old-style 10 amp charging
system is notorious for generating very few amps, about 3 amps more or less
maximum at full governed engine speed, and I have no idea why. I believe

A-1 Miller's Computerized Stuska Water Brake Engine Dynamometer (Dyno) Service with DPM Data Logger Software to Test Horsepower and Torque! | [Top of Page]
For performance testing of 10-16hp
single cylinder Kohler stock or competition pulling engines at speeds up
to 12,000 RPM. 100% accurate, customers can rent dyno time, fine tune and
make adjustments or changes to their engines to gain maximum horsepower and
torque, and print-out the results so their tractor(s) will be truly competitive
on the track. With an engine dyno, the puller can adjust their engine to
get maximum horsepower and torque, and gear their tractor appropriately to
have an advantage over the competition. NOTE: A fresh-built engine may
not produce full power until it's broke-in. This is when the valves wear-in
with the seats to completely seal in the compression. The rings will likely
hold the compression, but the valves may leak slightly until they wear into
the seats. This is normal for all engines and may take several hours or pulls
to happen, then the valves will be able to hold full compression. Lots of
pullers tell A-1 Miller's after I've built their engines that it seems to
pull stronger every time they pull it.
Engine Dyno Rental Fee: $50.00 per hour run time from the moment the engine is started. No setup fee for Cub Cadet engines with a 3- or 6-pin/stud clutch driver. An adapter may need to be needed or fabricated for other makes and models of engines. Only engines with the narrow base oil pan can be tested. Engines with the wide base (tall) oil pan cannot be tested at this time. [Return to Previous Section, Paragraph or Website]
