  Kohler Governor Cross Shaft Bushings with Rubber O-Ring
to Prevent Oil Leak. Rubber O-ring fits snug in bushing and on cross
shaft, and has no effect with movement of governor leverage whatsoever. WHY
HAVING THIS O-RING INSTALLED IS IMPORTANT: On single cylinder Kohler engines,
vacuum within the crankcase created by the upward stroke of the piston draws
in a small amount of outside air, along with a small amount of dust, dirt
and debris through the governor bushing and shaft, pressurized air within
the crankcase created by the downward stroke of the piston blows out a fine
mist of crankcase oil through the bushing and shaft. Overtime, the dust,
dirt and debris of this repeated pulsating action will, without a doubt,
cause the bushing (and sometimes the shaft, too) to wear, which causes a
thin film of oily mess to exist on the outside of the engine block. IMPORTANT
INFORMATION UPON REMOVAL OF THE BUSHING: When removing the old bushing, use
caution to prevent the governor cross shaft from pulling outward and possibly
falling down inside the crankcase! If this happens, the entire engine
must be completely disassembled just to reinstall the governor cross shaft
in place. Also, before installing this bushing with the O-ring, apply clean
oil inside the bushing and O-ring and/or on the shaft for lubrication. With
no prior lubrication, the dry bushing and rubber will eventually wear dry
from friction, possibly causing a new oil leak. Do the job right the first
time, and it won't have to be done again for a long time. Conceived and
precision machined by A-1 Miller's. Please do not accept an advertised copycat
product of this kind.

engine models K241, K301, K321, M10, M12, M14, K341, M16 and K361.
 Cast Iron Governor Gear
Assembly. Fits Kohler engine models K141, K160/K161, K181,
L160/L161, L181, M8, K241, K301, K321, M10,
M12, M14, K341, M16, KT17 (first design), KT17 Series II, KT19/KT19 Series
II, KT21, MV16, M18, MV18, M20 and MV20. Recommended for high RPM or
wide
open throttle competition pulling engines. Will not become distorted
or possibly explode at high RPM or at open RPM like the nylon governor gears
sometimes do. (Kohler never made a steel governor gear.) IMPORTANT: Apply
oil or grease on stub shaft to prevent wear or damage to governor gear assembly
upon engine startup until crankcase oil reach this area.
Thrust Washers for Governor Gear Assemblies. Fits Kohler engine models K241, K301, K321, M10, M12, M14, K341, M16, K361, KT17, KT17 Series II, KT19, KT19 Series II, KT21, MV16, M18, MV18, M20 and MV20. A thrust washer is required to prevent the governor gear from wearing against the engine block when the governor gear is under full pressure from the engine running at higher RPM. Many people are not aware of the thrust washer because it may appear to be part of the engine block, and it usually falls out and gets lost while cleaning inside the block. IMPORTANT: Apply oil or grease on stub shaft to prevent wear or damage to governor gear assembly upon engine startup until crankcase oil reach this area.
Governor Gear Stub Shafts. NOTE: Install each stub shaft listed below until .345" (11/32") protrudes from the block, and apply oil or grease on it to prevent wear to governor gear assembly to prevent a dry engine startup until crankcase oil reach this area. FYI - All OEM Kohler stub shafts that originally come in the engine are smooth the entire length. Only new OEM replacement stub shafts are knurled on one end. Therefore, perhaps the OEM stub shaft can be reused by reinstalling it in reverse if the worn half fits tight in the block.

High Quality Bearing Inserts for Connecting Rods.
Can be used in Kohler engine models K241, K301, K321, M10, M12, M14,
K341, M16, K361, KT19 Series II, M20 and MV20. Available in STD size,
.010", .020", .030" and borable/resizable .060" (limited supply) undersizes.
NOTE: Rod must be bored-out (and notched) to make
room for bearing inserts. And a rod with a burnt aluminum surface can be
bored-out and bearing inserts can be installed.
Click here to learn
how bearing inserts protect an engine. Rods for the before mentioned
engines can be bored and notched to accept bearing
inserts. Even severely burnt, scored, or rods with a mismatched cap can
be bored for installation of bearing inserts. Only USA-made Clevite 77, Federal
Mogul or Sealed Power bearing inserts will be installed. No low quality
Chinese-made bearing inserts ever installed. All A-1 Miller's Professional
Machined connecting rods include ground-out notches to prevent bearing rotation
in rod and drilled oil hole for proper lubrication. Please indicate diameter
of crank journal for size of bearing inserts. (STD size, .010", .020", .030"
or resizable .060" undersizes.) Also, rods can be center-bored for top of
piston to come flush with deck, or bored .020" offset for a .020"± piston
pop-out at no extra charge. [Return
To Previous Paragraph, Web Site or Section]
NOTE: If a crank journal is worn beyond specs or badly scored/burnt,it will need to be reground to the next undersize to match the appropriate size bearing inserts. And if you wish to have A-1 Miller's to bore a rod for you, please let me know if you want the bearing insert centered in the bore of the rod (5.300" rod length; piston flush with top of block), offset .020" (5.320" rod length; safe to use with a milled OEM Kohler stock head and stock head gasket) or offset .060" (5.360" rod length; use with a non-milled OEM Kohler head and stock head gasket) to pop the piston out of the cylinder (see below Ê) to raise the compression and help improve airflow within the combustion chamber for more power and torque. The bearing inserts A-1 Miller's install in Kohler 10-16hp flatheads and 18hp OHV K361 connecting rods can be used for general lawn and garden use, stock or high RPM competition pulling engines. The rod will need to be bored exactly 1.625" for correct bearing to journal oil clearance. NOTE: Being virtually all Kohler K241 and M10 pistons come within .020"± from the top of the block, which lowers the compression ratio. (The factory made them this way for reasons unknown.) A-1 Miller's prefer to bore the K241 10hp rods .020" offset so the piston will come flush with the top of the block. This will allow the engine to produce a little more power. It won't effect the longevity of the engine or cause any problems whatsoever. But sometimes with the .020" offset, the piston will pop out of the cylinder a few thousandths of an inch, which will still hurt nothing. And the bore can be offset .040" for a .020"± piston pop-out. FYI - Before A-1 Miller's machine a rod for installation of bearing inserts, we use a metal "plug" alignment tool that we fabricated to precisely align the big hole of the connecting rod with the centerline of the spindle in my milling machine. Then while the plug is in the rod, we firmly clamp the rod to the milling machine table and after leaving the big hole centered or moving the table so many thousandths of an inch offset for piston pop-out, we lock the table so it won't move in any direction while boring the rod. But for reasons unknown, sometimes the cutting tool will bore the hole in the rod slightly off-center toward one of the bolts or studs. When this happens, we simply grind a small notch on the outside of each bearing shell so they'll clear the rod bolt. I've talked to other machinists who bore Kohler rods also about this and they tell A-1 Miller's sometimes the same thing happens to their rods. But as long as the outside of the bearing shells are notched for clearance of the bolt or stud, the off-center of the bearing inserts poses no problems whatsoever. And bearing inserts for the 10-16hp Kohler engines can be installed in Kohler engine models K482, K532 and K582 STD size connecting rods, but the crank journals would need to be reground exactly to 1.500" to match the inside diameter of the bearing inserts when installed in the rods. And for your information, STD size crank journals for the K482, K532 and K582 engines measures 1.6245". |

| Valve Guides -
FYI - Valve guides are made of
either cast iron or bronze, and not steel. Cast iron and bronze are very
hard and porous metals. They absorb oil and lubricate the valve stems for
longer wear. NOTE: The alternative to installing
new replacement OEM-type valve guide(s) is to have the old [worn] guide(s)
reamed for installation of thin-wall bronze sleeves/liners (bushings), which
can be installed by an experienced and reputable automotive machine shop.
Thin-wall bronze valve guides are a low-cost and actually works better than
replacing the OEM guide in most engines. Bronze lasts longer than cast iron
guides because it is harder material and it retains more oil for better
lubrication of the valve stem.

 A-1
Miller's Valve Guide Removal and Installation Tool for use with all Kohler
K-series and Magnum engines. IMPORTANT: The engine block could crack if
guides are removed or installed with a hydraulic press! Therefore, it's
best to use a big, heavy hammer (with this tool) to drive out the old guide
into the valve spring compartment and use the same hammer (with this tool)
to install the new guide externally from inside the valve pocket. When installing
the new guide, be sure to hammer straight down in alignment with the guide
bore hole and not at an angle. Hitting the guide at an angle could cause
it to break. Install new guides until flush with the valve pocket. This tool
can be used with either OEM Kohler and aftermarket offset valve guides. Machined
at a 90º angle where the pilot meets the shank. Dimensions: .300" pilot
x 1/2" diameter shank x 5" overall length. A-1 Miller's part. $20.00
each, plus shipping & handling. [Return

 High Quality,
High Speed Steel Chucking Reamers. Precision ground to provide correct
stem to guide clearance. Will not allow valve stem to be too loose or too
tight in guide. When reaming guide, use an electric hand drill with plenty
of oil in guide. Before installing valve, apply motor oil on stem for lubrication
to reduce wear to guide and prevent valve from sticking.
[Return to Previous Section, Paragraph
or Website]

 Valve
Stem Seals. Required to prevent crankcase oil from draining down into
(OHV) or being suctioned into (flatheads) the combustion chamber through
the guide. Silicone rubber w/metal clamp. NOTE: Apply oil or grease on
valve stem before inserting valve through seal to provide lubrication of
the stem, guide and seal. Dimensions: 5/16" I.D. (stem) x .500" I.D.
(guide) x .600" O.D. NOTE: Some early production KT17 models do not use valve
stem seals.

 Automatic
Compression Release (ACR) Spring. This tiny [hair-like] spring is hard
to find part nowadays. Fits Kohler engine models K141, K161, K181, M8, K241,
K301, K321, M10, M12, M14, K341, M16 and K361. Fits later one-piece camshafts
with the automatic compression release (opens exhaust valve slightly upon
the compression stroke) and not the early two-piece camshafts with the automatic
spark advance. FYI - If you have a Kohler 7-16hp ACR camshaft that was
broke in two by a thrown connecting rod, save the spring off of it. It can
be used on another good cam that may not have one. Or if your ACR spring
places little or weak pressure against the flyweights/levers, it can be re-bent
or reshaped to its original condition to place sufficient tension against
the flyweights/levers.

New-Style, One-Piece, OEM
Kohler Camshafts with Automatic Compression Release (ACR).
NOTE: May or may not come with the tiny (hair-like) automatic compression
release (ACR) spring (see above). If required, reuse the spring off your
camshaft. IMPORTANT: Apply ample amount of clean
motor oil inside cam before installing to prevent seizing of cam on pin!
This will provide vital initial lubrication until crankcase oil reaches the
cam/pin when the engine is first ran. And when reusing
lifters, roughen lifter faces with 600 grit sandpaper to produce a new wear
pattern so the lifters will rotate slightly with every lift to prevent wear
to the cam lobes. Also, the lobes on these used cams have not been reground
for performance. [Top of

| Professionally Reground
4,000± RPM Performance Torque Cast Camshaft for
Kohler General-Use or Competition Pulling
Engines |
[Top of Page]
FYI - In order to gain the full benefit of a performance camshaft, just installing this type of cam will not greatly increase the power output of a Kohler engine. Along with the performance cam, the carburetor will need to be bored-out and reworked, the cylinder head will need to be milled .050" to raise the compression ratio, the valves/seats will need to be reworked, and installing an open/unrestricted exhaust header pipe will help, too. All of these things must work together so more air will enter the combustion chamber (and exit the chamber), which will build up more compression to allow the engine to produce more horsepower and torque.
FYI: When the cam lobes are reground, metal is removed from the base circle which reduce the diameter of the base circle in order retain maximum lift at the point on the lobe. The ramps on the lobes are also "rounded" to give the cam more duration. The cam grinding machine's grinding stones are about 1" wide, and after the cam grinding process, we have to manually grind metal away from the sides of the base circles so the edge of the lifters won't "ride up" on the ungrounded areas and hold the valves slightly open when they're supposed to be fully closed. We have to do this to every reground cam we have in stock. Some cam grinders apply a phosphate conversion coating (which resembles flat or matte black paint) to the entire camshaft, especially the lobes. This coating is to prevent galling (wear) during the break-in period and it also covers the secondary grinding areas on each side of the base circles of the lobes so they can't be readily easily seen or noticed. Motor oil with high zinc phosphate content will also protect the cam lobes and other internal moving engine parts from wear during break-in. Otherwise, if everything else is set up correctly with your engine, this cam should work fine. There's no need to be concerned when you receive the cam and see the metal ground away. Also, some of the cams we have, the points lobe is slightly worn. (It's hard to find a good used, 100% unworn cam nowadays.) we include a stainless steel points pushrod with a flared-end to make contact with the unworn areas of the lobe. The pushrod will need to be installed from inside the block before the cam is installed. IMPORTANT: To prevent seizing of camshaft on pin when engine is ran for the first time, apply plenty of motor oil on cam pin and inside cam before installing cam in engine. This will better protect the parts until crankcase oil reaches them.

|
|||
| FYI: The
OEM valve springs in various models of Kohler cast iron block engines are
not the same. They are not like the OEM springs that's used in a stock small
block Chevy V8's, which are the same. For some reason, Kohler installed a
specific valve spring in a certain model engine to match the cam profile
(lobe lift and duration) so the engine will perform best. And used valve
springs rarely lose adequate pressure. They can be reused as long as they're
not rusted or have been overheated. The rust-pitted areas is a weak spot
and when in operation and under pressure, the spring could
break.

 Valve
Keepers/Locks/Collets for all Kohler K-series and Magnum K141-K361 cast
iron engines, and KT series and Magnum twin cylinder flathead engines, including
K482, K532 and K582. Also fits 6hp-18hp single- and twin-cylinder Briggs
& Stratton exhaust valves. Can be used with 8mm valve stems and
high-performance valve springs listed above. NOTE: Valve keepers usually
don't wear or get damaged because they don't rotate on the valve stem. To
check yours, with a valve out of the engine, install a valve retainer or
rotator on the valve, then the keepers, and then pull back hard on the retainer
or rotator. If the retainer or rotator holds or squeezes the keepers tight
in the groove, then they can be reused. Can be used with 5/16" or 8mm diameter
valve stems. Replaces Briggs & Stratton part # 494553.

 Valve Lifters/Tappets.
Each fits Kohler engine models K241, K301, K321, K341, M10, M12, M14 and
M16. NOTE: Most unworn lifter/tappets can be reused, But if either of
your lifters/tappets have a worn groove where the base makes contact with
the cam lobe, lightly rub the base on 400 grit sandpaper tilted 1º to
give it a slight convex shape in a random motion to create a new crosshatch
wear pattern. And if there's a worn spot in the middle of the adjuster head,
the ridge can be ground away to make the head 100% flat again for a more
accurate clearance setting.

below are actually an oil trap. They trap and suspend oil droplets, and prevents
oil vapors from exiting out the crankcase vent at higher RPM, then they allow
the oil to drain back down into the crankcase when the engine is at idle
or turned off. (These are too coarse to be a filter of any kind, but Kohler
calls them a filter.)

Oil Level Check and Drain Plugs with Tapered Threads and Square Head
listed below. A-1 Miller's oil drain plugs have a super strong rare
earth/neodymium magnet. Five times stronger than competitor's ceramic (ferrite)
magnet and resists demagnetization. Plugs listed below can be used on various
other makes and models of transmissions, transaxles, gearboxes and small
engine crankcases. Tapered threads requires no sealing gasket or sealant,
and threads will not strip out when tightened. To avoid cracking oil pan,
do not over-tighten! When in doubt, use
plumber's thread sealing tape to insure proper sealing
of threads to prevent a possible oil leak. Universal application. Magnet
attracts and removes
ferrous
metallic wear fragments from the motor oil or transmission/gearbox to reduce
engine or gear/bearing wear. Sometimes some of the ferrous wear fragments
settle to the bottom of the oil pan and do not drain out with the oil when
performing an oil change, even when the oil is hot. Magnetic drain plugs
are suitable for engines with splash oil lubrication (no oil pump/filter).
The engine, transmission, transaxle or gearbox will last much longer with
uncontaminated and cleaner oil. Remember - metal flake looks good in paint,
not in oil. 
FYI - If you don't know or can't find any information on the maximum oil quantity for any specific gear drive transmission, transaxle, right angle gearbox, or garden tiller sealed chaincase or gearbox, well, the unit in question is full when oil runs out of the oil level check/fill plug hole that's located halfway [of the drive axles or lower output shaft(s)] on the side(s), front or rear of the unit. All of these fill this way. When the unit is in motion, the lower gears in a transmission or transaxle picks up the oil and slings it on the upper gears, shafts and bearings to lubricate them. And in automotive rear ends, the ring gear picks up the oil and slings it on the pinion gear, spider gears, shafts and bearings to lubricate them. Due to high friction between the gear teeth in transmissions, transaxles, right angle gearboxes and garden tiller gearboxes, or an "open" (non-locking, free-spinning) rear end or in an automotive rear end with a Detroit Locker, SAE 90 weight gear oil must be used. But in an automotive Posi-Trac limited-slip differential, SAE 90W140 weight gear oil must be used to prevent chattering of the locking clutches going around turns. And due to much less friction of roller chain(s) on sprocket teeth in a sealed chaincase, 10W30, 10W40 or SAE 30 weight heavy duty motor oil can be safely used. In front-wheel-drive vehicles, the differential is typically built into the transmission or transaxle, and shares the same transmission fluid, rather it be SAE 90 weight gear oil for a manual shift transmission or ATF for an automatic transmission.  1/8" NPT Oil Level and Drain
Plugs. (0.405" O.D. tapered threads.) All MTD-built Cub Cadet garden tractor
aluminum housing creeper drive units are packed with grease from the factory.
Therefore, for better lubrication and less wear inside the creeper drive
unit, install ordinary plug on opposite side of unit of shifter to serve
as an oil level check, and install magnetic plug on bottom of unit to attractive
metallic wear fragments and drain/change the oil. Entire creeper unit must
be completely disassembled and cleaned, a hole drilled midway on the side,
another hole drilled on the bottom, and both holes will need to be threaded
with an 1/8" NPT hand tap for the plugs. Then fill unit through the breather
opening with SAE 90 weight gear oil. $8.00 for both plugs, plus shipping
& handling.
 1/4" NPT Magnetic Oil Drain Plug.
(0.540" O.D. tapered threads.) Fits various Briggs & Stratton, Kohler,
Tecumseh, and various other makes and models of small engines. A-1 Miller's
part. Replaces discontinued Kohler part # X-75-2. $5.00 each, plus
shipping & handling.
 3/8" NPT Magnetic Oil Drain
Plugs. (0.675" O.D. tapered threads.) Fits various Briggs & Stratton,
Kohler, Tecumseh, and various other makes and models of small engines.
1/2" NPT Magnetic Oil Drain Plug. (0.840" O.D. tapered threads.) Fits side of oil pan on Kohler engine models K141, K160/K161, KV161, L160/L161, L181, K181 and M8 engines, and oil drain on Cub Cadet garden tractor transaxles, various automotive manual shift transmissions, and various other makes and models of small engines. A-1 Miller's part. Not available from Kohler. $5.00 each, plus shipping & handling. 3/4" NPT Magnetic Oil Drain Plug. (1.050" O.D. tapered threads.) Fits various Briggs & Stratton, Kohler, Tecumseh, and various other makes and models of small engines. A-1 Miller's part. Not available from Kohler. $5.00 each, plus shipping & handling.  5/8" I.D. Fiber Sealing Gasket.
Fits OEM Kohler 3/8" NPT Oil Drain Plug with Hex Head. Replaces discontinued
Kohler part # 241063. $1.00 each, plus shipping & handling.
 3/4-10 UNC (Straight Threads)
Magnetic Oil Drain Plug. Use to replace OEM Kohler 3/8" NPT oil drain plug
with stripped threads in [aluminum] oil pan. Includes fiber sealing gasket.
NOTE: Threads in oil pan must be enlarged with a 3/4-10 UNC hand tap.
A-1 Miller's part. $5.00 each, plus shipping & handling. |
 Super
Strong Rare Earth/Neodymium Magnets for Engines, Transmissions, Transaxles
and Gearboxes. Attracts and removes ferrous metallic wear fragments from
the lubricating oil inside an engine that does not have an oil pump with
an oil filter, or inside a transmission, transaxle or gearbox to lessen wear
and noise to gears and bearings. Sometimes some of the wear fragments settle
to the bottom of the oil pan, engine block or gearbox and do not drain out
with the oil when performing an oil change, even when the oil is hot. Install
magnet in bottom of oil pan away from the oil dipper and any moving parts,
or in bottom of a transmission, transaxle or gearbox away from rotating gears
and any moving parts. Use
Krazy Glue,
Super Glue,
Gorilla Glue, or any industrial strength adhesive to secure
magnet in place. The engine, transmission, transaxle or gearbox will last
much longer with uncontaminated and cleaner oil. These rare earth/neodymium
magnets are EXTREMELY strong! Use caution when handling! Can be difficult
to remove from a steel or cast iron surface, are very brittle and can break
easily if mishandled. Remember - metal flake looks good in paint, not
in oil.

pulling engines with stock-size or oversize valves running at 4,000±
RPM or at open RPM. High grade durable and galvanized-coated mild steel pipe
resists rust and will not rust or discolor, even from exhaust heat. Has a
90º, 4" radius bend; each pipe extends 8" from exhaust port to midway
of bend for plenty of hood clearance and measures 18" upward from midway
of bend. Kit includes 1-5/16" O.D. x 1.260" I.D. x 24" overall length header
pipe, 2-1/2" O.D. x 1-5/16" I.D. x 5/16"± thickness round mounting flange
and two 5/16-18 UNC Allen head bolts. Flange fastens directly to engine block
without a round mounting adapter and clamp, just like automotive engines
with headers. No gasket required; use
clear RTV silicone adhesive sealant instead of a gasket.
(Clear RTV silicone adhesive sealant is heat-resistant, it will NOT burn,
even with extreme exhaust heat.)
 FYI: When I have my 1-5/16" pipes
bent at a local automotive muffler shop, being there is no 1-5/16" I.D. die
to fit around the pipe, I use a 1-1/4" I. D. x 1-1/2" O.D. x 12" length steel
tube, split in two, with one half cut in two, then I place them inside the
1-1/2" die. And sometimes while the pipe bends, this creates slight crinkles
on the sides of the elbow, which will not interfere with the exhaust flow
whatsoever. Click photos to the right for a larger view.

| Information Concerning A-1 Miller's Professional Engine Rebuilding,
Build-Ups and Building Services -
FYI - The business world of older small engine parts have changed the last few years, and certain OEM Kohler and aftermarket engine parts are no longer available, but might still be available from a source in new old stock. We do our best to find high quality parts to rebuild your engine and so it'll run well and last a long time. We don't have any rebuilt Kohler short blocks or engines in stock. And if we did, chances are, they probably wouldn't be designed for your garden tractor, small motorized vehicle or equipment. Because Kohler engines are made specifically to fit a certain model of garden tractor, small motorized vehicle or equipment. They are not a "universal fit" or "one fits all". Therefore, it'll be best to have your engines rebuilt instead. Then all the brackets, accessories and electrical wiring will reconnect to your garden tractor, small motorized vehicle or equipment with no modifications. Also, we set the air/fuel adjusters on all carburetors just so the engine will start and run, but because of the altitude level, barometric pressure and air temperature where the engine will be used, the customer will need to make the final adjustments so the engine will run smooth. No carburetor with an adjustable high speed main fuel adjuster comes preset, not even new ones. Furthermore, just to let you know, although we use the best parts, use caution on choosing the right motor oil to use in your engine. Because the government (Sierra club/tree huggers) is requiring oil companies to lessen the amount of zinc in their motor oils to reduce pollution. Zinc provides a thin protective coating on internal engine parts and prevents metal to metal contact for proper break-in and it helps the parts last longer throughout the life of the engine. Many auto manufacturers and professional engine rebuilders are upset because of this too, because they have to guarantee their engines for a certain period of time, and many of them take pride in building their engines. Regarding an Engine Rebuild, Build-Up or Build from Scratch Estimate -
We're very meticulous in how we rebuild, build-up and build from scratch
our customer's engines. We pay close attention to the small details for wear
and tear on every part of an engine and replace or repair where necessary
so the engine will produce more power than before and last a long time. If
you would like to have A-1 Miller's rebuild, build-up your engine or build
an engine from scratch for you, we will need a detailed list of exactly what
you want done to your engine or a copy of your association/club sanctioning
engine rules and requirements regarding the engine requirements before we
can give you an estimate on the cost. And if you (the customer), change
your mind of how you want the engine rebuilt, built up or custom built in
the middle of a build, we will need to know ahead of time and we will need
the changes in writing so we can make the necessary changes to the engine.
Otherwise, this will effect how well the engine performs on the track, and
it would make us, as professional engine builders, look bad. Having confidence
in an engine makes you feel good, but having confidence in your engine builder
makes you feel better. A-1 Miller's competition pulling engines will be coated with high quality gloss black paint (most common factory color), International Cub Cadet yellow paint, Wheel Horse red paint or the color of your choice. When you receive your engine, install the baffle shields (sheet metal), brackets and everything else on the engine, install the engine in the tractor, add motor oil to the proper level, install the fuel hose, add fuel, connect the ignition and starter wires, connect the throttle/choke cable controls, and the engine will be ready to start. Carburetor adjustments will be initially preset just so the engine will start and run, but due to the altitude level, barometric pressure and air temperature where the engine will be used, the final idle speed, idle air/fuel mixture and high speed air/fuel mixture adjustments will need to be made by the customer after the engine is started and warmed up to operating temperature. Whenever we rebuild or build-up an engine, and if you would like to do so, we do whatever it takes so it'll produce the factory-rated horsepower or the maximum horsepower and torque, and last a long time. we go beyond what the repair manual says to do. we can get all the parts needed, too. we can build your engine so it'll be legal for the class you plan to pull in. And with my engine rebuilds and build-ups, you may not always win, but you'll look good trying! By the way - the surface of the exhaust area of a fresh-built engine may burn off the oil residue for a short time once it gets hot, but it'll stop after a while. It's nothing to worry about. This happens with most rebuilt engines, especially an engine with fresh paint. We build all competition pulling engines in accordance with your association's/club's sanctioning engine rules and requirements, or to your personal preference. Being different pulling associations/clubs have different engine rules and requirements, there is no "one pulling engine that conforms to each and every club's rules and requirements." We'll build your engine or an engine for you so it'll produce the maximum horsepower and torque, and not less than what your association's/club's rules and requirements allow. We also rebuild ordinary/stock lawn and garden equipment engines too, such as cast iron and cast aluminum block single- and twin-cylinder flathead, OHV and V-twin Briggs & Stratton, Kohler, Tecumseh and 2-cycle LawnBoy. I've never encountered an engine that we couldn't repair, rebuild or build-up/modify with more horsepower and torque! FYI - Used OEM parts in good condition for older Kohler engines are hard to find now, especially the small parts. If the parts don't wear, they tend to get thrown away and then "engine scrappers" sell the parts that do wear on places like eBay. They don't think about people like me, who make a living by "piecing together" or building engines from scratch for a customer. We can purchase new parts from Kohler if they're still available, but that would be cost-prohibitive. We try to keep my engine builds at reasonable prices. All of A-1 Miller's customer's competition pulling engine builds are strictly confidential! This means the people you pull against will not know what goes into your engine.
If you decide to bring your engine to A-1 Miller's in person and if you're the kind of person who don't trust delivery/shipping companies (mis)handling your high-dollar and fragile merchandise, you can make the long drive to A-1 Miller's shop to personally purchase parts, and/or drop off and/or pick up your carburetor, clutch assembly, engine parts, entire engine, transmission, transaxle, garden tractor, small motorized vehicle, etc. for repairing and/or rebuilding. "The road to a friend's house (or shop) is never long." Don't sacrifice quality workmanship for distance. If bringing an engine in the trunk of a car, bed of a pickup truck or cargo area of a vehicle, place it in a medium-size automotive tire for protection and to keep it from moving around and possibly getting damaged. Before shipping or bringing your engine to A-1 Miller's in person, we don't need everything on it. We need just the parts that can wear and require rebuilding or reconditioning, such as the carburetor, fuel pump, gear starter, cylinder head and crankcase breather assembly. I'll need the oil pan on it too, to prevent any dust and dirt from entering the crankcase after the rebuild. I'll need the flywheel on the engine so we can set the ignition timing. Please remove all baffle shields (sheet metal) and the PTO clutch assembly, too. By the way - As business is booming, we can rebuild the Cub Cadet garden tractor mechanical PTO clutch, too. We have a heavy duty 2-jaw gear puller that we use with a large C-clamp to remove/pull off the mechanical PTO clutch/pulley assembly from engines out of an IH Cub Cadet garden tractor. But sometimes these clutch/pulleys will not remove without breaking. We do all we can to try to prevent this from happening, but when they do break, we have no choice but to install a rebuilt PTO clutch/pulley assembly. We also made a special puller tool to remove the stamped steel PTO pulley/basket from the crankshaft without damage. Regular shop hours are 9:00 am - 5:00 pm, Monday-Friday. And we're open on weekends by appointment only. Please call, text or email me before coming so I'll be at my shop waiting for your arrival. If you are traveling a great distance, it's best to call in advance at 573-881-7229 (cell/text) to make sure that we will be here when you plan to stop by. Please ship or bring your engine when you're ready to the address below. [Return To Previous Paragraph, Section or Website]
Do not use a cardboard box alone and/or spray foam inside a cardboard box or wooden crate to secure the engine! Spray foam bonds the box or crate together and the box or crate might get destroyed when uncrating the engine. Crate the engine well using Phillips head screws only and brace the engine with wood so the engine and any parts included won't get damaged or lost in shipping.
When the work is completed, I'll contact you with the total including return shipping & handling. See further below for payment options. [Return To Previous Paragraph, Section or Website] |

keep our shipping cost to customers within reason. Therefore, we don't ship
our products in a fancy-looking package with our company name and/or logo
on it because most customers will just toss it in the trash after they remove
the contents. And being there is no USPS tracking number outside the US,
all I can do is make sure I write your address correctly on the customs form
and on your package.
My websites are not set up to process orders and accept payments. Therefore, I will need your name, complete and correct postal mailing address and phone number. And for payment options, I accept cash (in person), USPS Postal Money Orders, cashier's checks and business checks. I do not accept credit/debit cards. Or to make a payment to me through PayPal, please click this link: https://www.paypal.com (username: pullingtractor@aol.com).

fatigue, sometimes the lever on this shaft will break off. When this happens,
the engine will run dangerously at wide open throttle. Therefore, it'll be
a good idea to weld the lever to the shaft. But the entire engine must be
completely disassembled to replace this part. Also, before installing, apply
oil or grease on shaft for smooth governor action and less wear to shaft
and/or bushing. Replaces discontinued Kohler part # 237455 (cross shaft

High Quality 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

For Kohler engine models K241,
K301, K321, M10, M12, M14, K341, M16 and K361. This particular cam profile
design is suitable for heavy lawn and garden work, snow removal, etc., or
stock competition pulling to provide more torque (lugging power) and improved
engine performance from 3,800 to 4,200 RPM. The lobes on this cam are not
welded up. They are professionally and precision reground on a cam grinding
machine to have the factory stock lift, but with slightly increased duration,
which makes it perform best around 4,000± RPM. This cam will pass tech
for a stock cam. It will add about 3 more horsepower and 2 ft. lbs. of torque
to the average stock engine with more lugging power than the OEM Kohler K361
cam.
This cast cam performs best with our performance
BLUE valve springs (listed below; to
prevent fuel spray out the carburetor and lifter chatter), race-quality retainers
(or the OEM Kohler stamped steel retainers can be used), quality valve job,
ports made larger, and a reworked carburetor with a bored-out venturi for
maximum performance for competition pulling. If there's any restriction of
airflow in and out of the combustion chamber, the cam will not perform at
100% efficiency. This cam builds up the compression about 6% more than the
K361 cam, and approximately 11% more than the flathead engine cams at around
4,000± RPM. This cam sounds just like an OEM Kohler stock cam. You can't
hear the difference out the exhaust. The duration and centerline of the lobes
on this cam helps the engine produce the most power and torque between
3,600-4,500 RPM. At higher RPM, due to the limited duration, no substantial
gain in power or torque will result. If the engine is built to the max, tractor
is geared correctly and traction is adequate, engine shouldn't bog down much
with this cam. It'll keep pumping out the ponies right out the gate! Use
with the OEM Kohler 1" base lifters. When reusing lifters, roughen lifter
faces with 600 grit sandpaper in an erratic pattern to produce a new wear
pattern and so the lifters will rotate slightly with every lift to prevent
wear to the cam lobes. Use the
