  Kohler Governor Cross Shaft Bushings with Oil Seal to Prevent
Leaking Oil. Rubber lip seal or rubber O-ring fits snug in bushing and
on shaft, and have no effect with movement of governor leverage whatsoever.
WHY HAVING AN OIL SEAL 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, then pressure
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 creates a
thin film oily mess 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 drop down
inside the crankcase! If this happens, entire disassembly of the engine
will be required to reinstall governor cross shaft. And before installing
any new oil seal, always apply clean oil or grease inside the seal and/or
on the shaft to keep the rubber lubricated. With no prior lubrication, the
dry rubber will wear away from friction, eventually causing another oil leak.
Do the job right the first time, and it won't have to be done again for a
long time.

for Kohler engine models K241, M10, K301, M12, K321, M14, K341 and M16 used
with an air compressor, generator and/or welding unit. Also ideal for
use in a 4,000± RPM competition pulling engine. Recovers engine RPM
quickly when under a load and maintains engine RPM at a more steady pace.
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.

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 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.

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.
Fits Kohler engine models K241, M10, K301, M12, K321, M14, K341, M16,

   Throttle
Stabilizer/Anti-Surge Springs. Install either of these lightweight springs
between the governor lever and throttle lever to remove free play (looseness)
in the linkage end connections to reduce erratic engine behavior at top governed
speed due to throttle flutter for a smoother running engine and reduce wear
to throttle shaft. Can be used on virtually any Briggs & Stratton, Kohler
K-series, Magnum or Command single- or twin-cylinder cast iron or aluminum
block engine. May need to drill a small hole with
chamfered edges in either lever close to linkage connection
to install spring. A must for a generator, welder or a 4,000 RPM± governed
competition pulling engine. With a governed pulling engine, throttle flutter
causes the engine RPM to momentarily spike, which could cause the
rear tires to momentarily lose traction
(jerk), resulting in a possible shorter distance pull.

| FYI - Piano or music wire, which is very hard solid steel wire, can be used to replace most obsolete OEM throttle and/or choke wire links for various small engines. Usually .080" (5/64" or 2mm) is the most common size. A torch will be needed to make any bends and the "Z" bend at each end. Actually, this type of wire can be used for many different things. Just because it's called "piano or music wire", don't mean it's just for pianos or musical instruments. Piano or music wire is available online and at most Ace Hardware stores. |

 Heavy Duty
Carburetor Throttle Cable Bracket Kit for Open RPM Kohler K241, M10, K301,
M12, K321, M14, K341, M16 and K361 Hot Stock, Stock Altered and Missouri
Super Stock Competition Pulling Engines with the Carter or Kohler #26, #28
or #30 Carburetor. Bracket fastens on fuel inlet side of carburetor.
Ideal for use with a billet cylinder head or could be used with a stock head,
and with or without a carburetor extension/intake stand-off.
This design allows for less wear to the throttle shaft and/or carburetor body, which would eventually cause a vacuum leak that could cause damage to the engine, and then installation of a bronze throttle shaft bushing and/or replacement of the throttle shaft will be required. To install the bracket, the two unthreaded bosses/shallow holes on the fuel inlet side of the Chinese-made aftermarket Kohler-replicated or OEM Carter or Kohler #26, #28 or #30 carburetor body must be drilled into the float area with a 5/32" drill bit, and threaded with a 10-24 UNC hand tap for installation of the two supplied 10-24 UNC x 3/4" length Allen head mounting screws with split lock washers. No fuel should leak out of the threaded holes with the bracket installed. And the hole in the throttle lever will need to be drilled-out/enlarged to 15/64" / 6mm for the throttle cable swivel. The supplied compression spring (as shown in the photo) returns the throttle lever to idle and it lessens wear to throttle shaft, and supplied small thrust washer prevents the end of the spring from sliding onto the cable housing when it's under full pressure at open RPM. And to avoid excessive wear and possibility of breaking of the throttle shaft, do not to set the cable so it pulls the throttle shaft beyond its normal range of rotation when in the wide open position! Kit includes: heavy duty steel bracket, two 10-24 UNC x 3/4" length Allen head screws w/lock washers, cable clamp w/screw and lock washer, compression spring, small thrust washer and throttle cable swivel assembly. Use with stranded throttle cable and foot pedal assembly. (Listed below.) Complete Kit: $75.00 each, plus shipping & handling. [Top of Page] Return To Previous Paragraph or Section |

IMPORTANT - Before installing
any new oil seal, always apply oil or grease inside the seal and on the shaft
to keep the rubber lubricated and cool until internal oil can reach it. With
no prior lubrication, the dry rubber will wear away from friction, eventually
causing another oil leak. Do the job right the first time, and it won't have
to be done again for a long time.

Because with "complete" engine rebuild kits that others offer, they always sell you extra parts your engine don't need, and/or leave out parts your engine do need. Completely disassemble your engine to determine which parts your engine needs and if the cylinder in your block and crank journal needs machine work performed, then email me a list of parts. Include the engine's model and specification numbers, too. [Top of Page]
| NOTE: All parts listed below are NEW, unless otherwise stated. A-1 Miller's do not sell cheap junk! As a matter of fact, most OEM Kohler parts are made in China now. Kohler owns some of the factories in China that make the parts. And most aftermarket parts are also made by Kohler in China. Kohler just place the part(s) in a generic box and sell them for less money. So when purchasing a genuine OEM Kohler part that comes in a box with the Kohler name on it, you're really just paying more money for the name. And as far as some parts being no longer available - either the parts didn't sell well or the EPA is trying to phase out parts for the old cast iron block flathead engines because they produce more air pollution than the newer OHV engines. |

| NOTE: High-quality ring sets, pistons and piston/rings assemblies are also available for other makes and models of small gas engines. And the piston assemblies that's offered here will work with a stock connecting rod and crankshaft without the need for rebalancing. And always match a billet connecting rod of a certain length to an aftermarket piston (Arias, JE, etc.) that has the correct compression height. These two parts must be matched for the piston to come flush with the top of the engine block, or have a few thousands of an inch pop-out. If using a Kohler connecting rod, the compression height may not be correct with an aftermarket piston (Arias, JE, etc.) that has the wrong wrist pin offset. The same is true with a Kohler piston and a billet connecting rod of a the wrong length. You can find piston ring compressors on eBay. |

Upon installation of a connecting rod in a Kohler
engine, the oil hole in the cap face toward the camshaft! There's "match
marks" on both the rod and rod cap. They MUST be aligned or "matched up"
so the big end of the rod forms a perfect circle around the crank journal
when installed. Otherwise, if the cap is installed backwards, the "perfect
circle" will be oblong or "egg-shaped," which will bind on the crank journal.
And DO NOT over-tighten the rod bolts or nuts! If the threads strip out in
a rod, then perhaps a longer grade 8 fine thread bolt can be installed in
reverse to serve as a stud (the rod will need to be machined for head bolt
clearance) and use a grade 8 nut. If this cannot be done, then the rod is
scrap metal. |
 Connecting rods. Fits
Kohler engine models K90/K91. NOTE: Crank journal must be reground
.010" undersize to match this rod. The alternative to using an undersize
rod is if a STD size or .010" undersize rod is in good condition, if the
matching-size crank journal isn't deeply scored and/or badly burnt, it can
be reground until it's perfectly round again and then if the original rod
also isn't deeply scored and/or badly burnt, it can be resized to fit to
odd-size undersize journal with the factory recommended .0025" oil clearance.
NOTE - The maximum a connecting rod can be resized to is .005" undersize.
If it's resized more than .005", being the big hole in the rod will be made
excessively oblong or egg-shaped, which will allow it to make less bearing
surface contact around the crank journal after being resized, due to the
centrifugal force at 3,600 RPM, the big end of the rod could become elongated
(metal stretch) and might eventually knock and possibly break. IMPORTANT:
To prevent scoring of the rod when the engine is started for the first time,
apply oil or grease or on crank journal before installing rod. This will
better protect the parts until crankcase oil reaches them.

  New Connecting
Rods. Fits Kohler K-series and Magnum models K301, M12, K321 and M14 cast
iron block flathead engines. Comes with long dipper. 5.3" length.
NOTE - These rods can be bored for installation of bearing inserts,
and crank journal must be reground to match diameter of undersize bearing
inserts. Crank journal must be reground .010" undersize to match this rod.
The alternative to using an undersize rod is if a STD size or .010" undersize
rod is in good condition, if the matching-size crank journal isn't deeply
scored and/or badly burnt, it can be reground until it's perfectly round
again and then if the original rod also isn't deeply scored and/or badly
burnt, it can be resized to fit to odd-size undersize journal with the factory
recommended .0025" oil clearance. Bearing inserts cannot be used. NOTE -
The maximum a connecting rod can be resized to is .005" undersize. If it's
resized more than .005", being the big hole in the rod will be made excessively
oblong or egg-shaped, which will allow it to make less bearing surface contact
around the crank journal after being resized, due to the centrifugal force
at 3,600 RPM, the big end of the rod could become elongated (metal stretch)
and might eventually knock and possibly break. IMPORTANT: To prevent scoring

High Quality Bearing Inserts for Connecting Rods.
Can be used in Kohler engine models K241, M10, K301, M12, K321, 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". |

 Crankshaft
Main Bearings (Flanged Sleeve Bushings). Fits Kohler opposed twin cylinder
engine models MV16, KT17 (first design), KT17 Series II, KT19 (first design),
KT19 Series II, KT21, M18 MV18, M20 and MV20. NOTE: With these engines,
if one main journal is worn beyond specs (mostly likely the PTO end due to
metal/dirt/debris contamination in the oil because of infrequent oil changes
and/or lack of an oil filter), it can
be reground undersize, and if the other main journal (most likely the flywheel
end) measures within specs (1.742"), it can remain STD size. Remember - metal
flake looks good in paint, not in oil.

 High
Quality 8 Ball Main Crankshaft Radial Bearings. Fits Kohler K-series
and Magnum cast iron block engine models K241, M10, K301, M12, K321, M14,
K341, M16 and K361. Heat treated chrome steel (AISI 52100) for higher resistance
and durability. Supports up to 17,000 RPM. Works excellent for general lawn
and garden engines or for high performance competition pulling engines that
run at high RPM or at
wide
open throttle. FYI - The 8 ball roller bearings have larger diameter
balls than the aftermarket 12 ball roller bearings, that have smaller balls.
Therefore, the balls in the 8 ball bearings rotate slower, causing less friction.
They run freer and more cooler. In
theory, it seems that the 12 ball bearings would work better
in an open throttle pulling engine, but in
reality, it's a different story. Dimensions: 1.57" (40mm)
I.D. x 3.54" O.D. (90mm) x .90" (23mm) width. See note below
Ê. NOTE: If your bearing(s) have more
than .005" of play due to wear, or it feels rough or "rubbles" when rotated
by hand with motor oil applied, then it should be replaced. FYI -
All US and import manufacturers of ball bearings have always been made them
to the metric dimensions. Where applicable, the manufacturers try to make
them close as possible to the inch dimensions.

| 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.

 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,
M10, K301, M12, K321, 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.

 A-1 Miller's Professional
Repair Service - Mill approximately .050" from Kohler K241, M10, K301,
M12, K321, M14, K341 or M16 cylinder head to raise compression ratio
approximately .75:1 to increase horsepower and torque. Includes remove
prominent/raised gasket mating surface from head and deburr sharp edge around

NOTE: To lessen the chance of a blown or leaking head gasket, clean out the head bolt hole threads with a tap, and seal the head gasket with Copper RTV Silicone Sealant (VersaChem - Mega Copper Silicone, Permatex® Ultra Copper® Maximum Temperature RTV Silicone Gasket Maker or Copper SPRAY-A-GASKET Hi Temp Adhesive Sealant) on each side of the head gasket or cylinder head and engine block to prevent a blown or leaking head gasket. Because engine heat has very little effect on silicone rubber. It's made of fine-ground up heat-transferring compressible copper mixed with silicone. Walmart and most auto parts stores sell copper RTV silicone sealant. It doesn't matter which brand to use, they work the same. |
A-1 Miller's Professional Repair Service - Professionally weld up burned-out gasket surface in small engine cylinder head, resurface on a wide, flat belt- or disc-sander/grinder to remove any warpage and restore flatness, and redrill bolt hole, if needed. The welding process involves grinding away the impurities in the aluminum, and the aluminum welding becomes integrated with or part of the aluminum in the head, resulting in superior bonding with no separation whatsoever. NOTE - As long as there's no cracks in the head, it can be successfully welded up, resurfaced, and the bolt hole redrilled. IMPORTANT - The two causes of a burn-out are: 1) Throttle shaft in the carburetor is severely worn, allowing extra air in the combustion chamber, which will lean out the air/fuel mixture at high RPM; 2) The adjustable high speed main air/fuel mixture screw is set too lean; 3) The engine is ran above 3,200 RPM with a [Walbro] carburetor having a fixed/non-adjustable high speed main jet. To prevent the burn-out from happening again, either of these things should be fixed correctly before the cylinder head (engine) is put back into service. $75.00 for welding and machining, plus return shipping & handling. If it's repairable and reusable, do not discard your cylinder head or other Kohler parts. Most discontinued OEM Kohler parts in good, reusable/rebuildable condition are hard to find nowadays, and nothing works better than the original part(s) the engine is designed for.

A-1 Miller's Professional Valve Repair Service for Kohler Engine Model K361 Cylinder Head. This service is for an engine that does not blow blue smoke out the exhaust and burn/consume oil. Performing a professional valve job restores full compression, which allows the engine to start quicker, idle smoothly without stalling, and (if the ignition timing and carburetor adjustments are set correctly, too), it will produce full power at top governed speed. Click or tap here for cylinder head bolt torque specs. And if you've ever wondered how the K361 rocker arms receive plenty of oil to keep them lubricated, when the engine is running at full governed speed, internal air pressure from the downward stroke of the piston forces crankcase oil through the pushrod tubes onto the rocker arms. Prices may change without notice. [Top of Page] Prices are subject to change without notice.

The ones that's listed here are the most common lengths. When installed correctly and torqued to specs, head studs provide even torque pressure for better head gasket sealing. Plus, with a thinner cylinder wall with a huge, oversized piston, they help maintain cylinder wall stability and straightness for better ring seal to lessen the loss of compression. Thoroughly tested for several years of continuous use under pulling conditions, for Kohler engine models, hardened and heat-treated coarse thread studs, along with grade 8 nuts and washers, works just fine, with no problems. The nuts maintain their torque as long as they're tightened to the correct torque specs. And make sure at least 3/4" of threads are in the block so the cylinder wall will not distort and threads in block will not strip out when the nuts are torqued to specs. Click or tap here for cylinder head bolt torque specs. Also, stud length is determined by type of cylinder head. The OEM head with short bolt holes require 2" length studs, the head with tall bolt holes require 2-3/4" length studs. Please indicate length of studs when placing order. IMPORTANT: As with any threaded stud, apply medium strength liquid threadlocker (Blue Loctite, Permatex or equivalent) on threads that goes in the block and tighten with pliers to prevent stud from loosening. Use a hardened steel flat washer under nut to distribute load evenly on head and apply motor oil on exposed threads so nut will torque correctly. Torque each nut to 360 in. lbs. or 30 ft. lbs. in correct sequence. FYI - When storing an opened container of liquid threadlocker or Super Glue, store it upright and not laying flat. The [capped] tip will not dry out and clog when stored upright. [Return To Previous Paragraph, Section or Website]

Superior Quality, High Velocity 12 Volt Auxiliary Engine Cooling Fan. Use an electric fan to cool a competition garden tractor pulling engine with a steel flywheel and no cooling fins. Unlike fan blades that's fastened to the flywheel, an electric fan will not produce drag and rob power from the engine. Install fan with motor forward of blades (for maximum velocity) aimed toward exhaust area of engine. Fasten fan housing on a sturdy angle steel support brace with 1/4" bolts, flat washers, lock washers and nuts, in front of engine or behind grille in a garden tractor. See photos to the right and below. No need to mount fan housing on rubber grommets; these will serve no purpose whatsoever. Fan motor is 100% secured and reinforced to plastic housing to withstand severe engine vibration to prevent fan motor from loosening and become inoperable when pulling. Distinctive feature by A-1 Miller's. Draws 2.6 amps, produces 145 CFM. Measures 3" diameter and 5" length. IMPORTANT: It's recommended that the fan not be run while pulling because due to normal engine vibration, the brush holders inside motor could break. Turn fan on ONLY between pull-offs or when tuning engine. $40.00 each, plus shipping & handling.

Crankshaft Regrinding - This service includes Briggs & Stratton, Kohler, Tecumseh, etc.
"Round Up" Crankshaft Rod Journal(s) and Resize Connecting Rod(s) - This service is for most makes and models of small engines when an undersize connecting rod or bearing inserts isn't available, if the crankshaft is worn beyond .010" and needs to be reground again, the journal can be reground to wherever it "cleans up" or is true again, then the connecting rod can be resized so it'll fit the smaller undersize journal with the factory recommended .0025" oil clearance. To resize the rod so it'll fit to a few thousands of an inch smaller diameter crank journal, first, metal is removed from the mating end of the rod cap, then the cap is fasten to the rod. The big hole in the rod is now oblong or "egg shaped." Then the big hole in the rod is honed until it's .002" larger than the diameter of the crank journal. Honing reshapes the hole into a perfect circle again, only smaller in diameter. This works very well and it lasts as long as an ordinary STD size rod and crank journal. This can only be performed on a rod with a good bearing surface. It cannot be done on a burnt or heavily scored connecting rod because too much metal would need to be removed. If you're interested, we will need your crankshaft and connecting rod(s). NOTE - The maximum a connecting rod can be resized to is .005" undersize. If it's resized more than .005", being the big hole in the rod will be made excessively oblong or egg-shape, which will allow it to make less bearing surface contact around the crank journal after being resized, due to the centrifugal force at 3,600 RPM, the big end of the rod could become elongated (metal stretch) and might eventually knock and possibly break. NOTE: Once installed and in operation, there is no warranty or guarantee of any kind on crankshaft regrinds.
Precision Dynamic Spin-Balance Service - If your engine vibrates excessively or more than normal, and if the parasitic accessories or attachments are not out-of-balance, then chances are, the rotating assembly (crankshaft, connecting rod and piston assembly, and/or flywheel) needs to be precision balanced.

Oil Level Check and Drain Plugs, Oil Filter Adapter, Oil Filters and OEM Kohler Cast Aluminum and Cast Iron Oil Pans - Please contact A-1 Miller's if you're interested in purchasing any of the products or services listed in this website.

| 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

 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.

  Oil Filter Adapter Kit.
Fits Kohler engine models KT17 Series II, KT19 Series II, MV16, M18,
MV18, M20 and MV20. (Will not fit KT17 (first design), KT19 (first design)
or KT21 engines because there is no provision on the block for an oil filter
adapter.) Oil filter not included with kit; order separately (listed below).
Having an oil filter helps the engine last much longer between oil changes
by filtering out or removing small metallic wear fragments and solid contaminants
from the oil that can cause excessive wear to the pistons, piston rings,
cylinder walls, and especially the PTO end main journal on the crankshaft,
resulting in low oil pressure, and possibly a burnt #1 connecting rod.
Remember - metal flake looks good in paint, not in oil.
NOTE: Use the 1/8" NPT Allen
pipe plug (Kohler part # 25 139 60-S) to plug the hole in the adapter body
on model M18 engines w/specification # 24532, after serial # 1835400002 (1988
and later) if the engine is not equipped with a low oil shut-off sensor,
oil pressure switch or oil pressure gauge. However, the adapter body can
be drilled and threaded with an 1/8" NPT tap to use a low oil shut-off sensor,
oil pressure switch or oil pressure gauge on models KT17 Series II, KT19
Series II, MV16, M18, MV18, M20 and MV20.

 Bolt-On Header Pipe Kits. Fits
Kohler Engine Models K241, M10, K301, M12, K321 and M14. For competition
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. By the
way - Silicone is heat-resistant, it will NOT burn out, 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.

  A-1 Miller's Professional Repair Service - Perform Valve
Job Only on opposed twin cylinder Kohler KT-series and Magnum engine models
KT17 (first design), KT17 Series II, KT19 (first design), KT19 Series II,
KT21, MV16, M18, MV18, M20 and MV20. This service is for an engine that
does not blow blue smoke out the exhaust and burn oil. Performing a professional
valve job restores full compression, which allows the engine to start quicker,
idle smoothly, rev up with no hesitation, produce lots of power, and run
for a long time without stalling or dying (when the ignition timing and
carburetor adjustments are set correctly, too). Labor includes: regrind four
valve faces and seats, lap in valves with valve lapping compound, reset valve
clearances to factory specifications (on short block only), resurface both
cylinder heads on a wide, flat
belt- or disc-sander/grinder to remove any warpage and
restore flatness, reinstall intake manifold and governor linkage. And
being some valve guides wear beyond specifications, there will be an extra
charge for installing and reaming new guides, if needed. The baffle shields
(sheet metal), muffler, intake manifold and governor linkage will need to
be removed before bringing or shipping engine/short block to A-1 Miller's
(new) shop. To save on shipping cost, only the cylinders (removed from the
crankcase) and valves can be shipped in two 12-1/4" x 12-1/4" x 6" USPS Large
Flat Rate Boxes. Place one box inside the other to double the strength, and
use rigid packing material under, over and around/between the parts to prevent
any of the fins from breaking off during shipment.
But the
short block must be shipped in a sturdy wooden crate. Prices listed
below with your cylinder heads/jugs or engine on my work table. Please
contact A-1 Miller's if you're interested in having
a professional valve job performed on your KT17, KT17 Series II, KT19, KT19
Series II, KT21, MV16, M18, MV18, M20 and MV20 cylinder heads/jugs or engine.
Perform Factory Valve Job with Stock Size Valves in Single Cylinder OEM [Kohler] Engine Block - Regrind both valve faces and seats to factory specs, lap in valves, reset valve clearances, and reinstall valves on a single cylinder Kohler engine. $50.00 labor, plus return shipping & handling. Perform High Performance Valve Job with Stock Size Valves in Single Cylinder OEM [Kohler] Engine Block - Grind intake valve face and seat to 30º/31º and regrind exhaust valve face and seat to 45º/46º, undercut both valve heads for maximum airflow, lap in valves, reset valve clearances, and reinstall valves on a single cylinder Kohler engine. $75.00 labor, plus return shipping & handling.

| 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. |

Break-In (Wear-In) Oils and Procedure for Newly
Rebuilt Lawn and Garden Engines -
Break-In (Wear-In) Oils and Procedure for Newly Built/Rebuilt Pulling Engines -
If the tractor is geared correctly, the pulling engines I build should not run out of power at the end of the pull. It should spin the tires. But there's some things that needs to be checked after a few pulls as the engine breaks-in and parts wear into each other. For gas fuels, the ignition timing needs to be set at 22° BTDC. And make sure the high speed fuel mixture screw is set so the engine runs smooth at high RPM. NOTE: If a high-output/performance ignition coil is used, it require two ordinary (Kohler) condensers or one high-capacity/performance condenser. This is so the coil will produce full voltage. And with a high-output/performance coil, the spark plug gap can be set at .060". With an ordinary coil, it should be set at .035". The valve to lifter clearances may need to be reset at .010" for the intake and .014" for the exhaust. Furthermore, when a new or rebuilt engine needs to "break-in," what the term "break-in" actually means is the moving internal parts that make contact with each other needs to "wear-in" with each other so they'll produce a wear pattern and last longer. Any new or rebuilt engine, rather if it's for general lawn and garden use, snow removal or for competition pulling, needs to fully break-in (wear-in) for it to produce full power. Rings don't "seat," they break-in, or wear-in with the cylinder wall, and they wear-in quickly. But the valves are the parts that needs to "seat." Being the valve faces and seats have different angles (30°/31° or 45°/46°, respectively), the valve faces needs to wear into the seats to seal in the compression 100%. Wear-in will produce a 30½° or 45½° angle on both the matching valve face and seat. The harder material the valves are made of, the longer it takes for them to wear-into the seats. Go here for more information: Valvoline.com > FAQs > Motor Oil Car FAQs > Racing Oil. Return To Previous Paragraph, Web Site or Section È Valvoline.com FAQs Motor Oil Car Racing Oil. [Return to Previous Section, Paragraph or Website] What makes crankcase oil to have a black appearance after a while is caused by blow-by of the combustion process due to either: excessively wide gaps in worn piston rings; carburetor flooding; idle air/fuel mixture set too rich, resulting in engine running rich on fuel; or prolonged slow idling with a [high-performance] long duration camshaft. The excessive unburned/partially burned gas will seep past the piston ring end gaps and into the crankcase oil, contaminating and diluting it, eventually break down the protective additives in the oil, causing sludge, resulting in premature wear to internal moving parts. This is why it's so important to have a "fine tuned engine" and change the oil regularly. Remember - fresh, clean oil in an engine is cheaper than a new engine or engine rebuild! Oil Refill Quantities for Older Kohler Engines - IMPORTANT: Make sure the correct oil dipstick is used and it's calibrated correctly! *NOTE: Add 1/8 quart for a competition pulling tractor that have a single cylinder longitudinal engine with a lowered front-end.

NOTES:
Ship the Engine Securely Fastened Inside a Sturdy Wooden Crate - [Return To Previous Paragraph, Section or Website]
Before shipping or bringing your engine to A-1 Miller's in person, we don't need everything on it. Just the parts that can wear and need 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 (573-544-9008 (new number; land line) | 1-573-881-7229 (cell; call or 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. Ê
If you bring your engine to
A-1 Miller's in person, place it in a medium size automotive tire for protection
and to keep it from moving around in the bed of a pickup truck. But if you
decide to ship your engine to A-1 Miller's, first off, do not use the
USPS, UPS or FedEx Express! We and our customers have had too many problems
with these shippers in the past. Their clumsy, incompetent and uncaring
"gorilla" workers have a tendency to damage heavy items,
and the shipping company's insurance rarely pay off. The shipping company
claim that the damaged item, which was in their possession, is "not their
fault." They are very careless with heavy packages when they handle them.
The packages are placed on conveyor-belt systems and they seem to always
drop the heavy ones off of the elevated conveyors, which usually destroys
whatever is inside them. Or 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 (new) shop to personally purchase parts, 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.
By the way - As business is booming, we're going to relocate our business soon at 12091 N. Rt. B, Hallsville, MO 65255 with a bigger, better, fully insulated, heated and air-conditioned building/shop (shouse) so we can provide many more high quality parts and professional services, and hire more help to have our customer's parts orders fulfilled sooner, parts repairs and engine rebuilds performed promptly without delay. We will also provide pick up and delivery service and perform professional repairs for various small engines and lawn & garden equipment! Photos of our new building/shop are posted here!
If shipping an engine, and if the crated engine weighs no more than 150 lbs., use only FedEx Ground for dependability. The average crated cast iron block Kohler engine weighs just under 150 lbs. Use this website to calculate the shipping cost for your engine: FedEx Rates and Transit Times. Contact your local FedEx Ground shipping center for more details and to schedule a pickup or drop off the crated engine at your local FedEx Ground shipping center. FedEx Ground is the only reasonably-priced shipping service that we know of for items up to 150 lbs. US Mail only ship up to 70 lbs. And FedEx Freight would cost almost as much as an engine is worth. If your engine is too heavy to go with FedEx Ground, partially disassemble it and send the lightweight parts in a USPS Large or Medium Flat Rate Box, and then send the main short block with FedEx Ground, the crated engine can be shipped through Fastenal. This also works better to save money on shipping costs. Or to save on crating and shipping charges, you can visit A-1 Miller's (new) shop at 12091 N. Route B, Hallsville, MO 65255 to drop off and pick up your engine(s) .
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.
A sturdy and well-constructed wooden crate can be ordered from: Crates, Wooden Crate in Stock - ULINE. But to construct your own sturdy wooden shipping crate, use 2x2's or 2x4's lumber for the frame work, with 1/4" plywood or 1/2" chipboard as outer covering (do not use cardboard for covering because another person's package could penetrate it and cause damage the engine inside), and a couple of 2x4's or a cut-down shipping pallet on the bottom so a forklift can move it without damage. Make the crate compact as possible so it'll take up less space, save on shipping charges and so it'll be easier to move around in our shop. Fasten the engine oil pan mounting bolt holes to two sturdy 2x4's on the base of the crate securely with 3/8" diameter bolts with wide flat washers. It's also very important to install 2x4 wood bracing all around the engine cylinder (front, rear and each side) stabilize it in the crate. And for easy engine removal, PLEASE use Phillips head drywall/sheetrock screws or better yet, use hex head 1/4" lag bolts w/flat washers to fasten everything on and in the crate. Be sure to include a note in a sealed plastic bag with your name, complete and correct postal address, phone number, email address (in case we have any questions) and a detailed description of how you want the engine built and what it will be used for, and mention in the note any other parts you may need.
When the work is completed, I'll contact you with the total including return shipping & handling. For payment options for parts ordered or services performed, or to make a donation to my websites, we accept cash (in person), USPS Postal Money Orders, cashier's checks, business checks, MasterCard, VISA, Discover, American Express (please add 2.5% to the total for the credit/debit card processor's surcharge), Western Union Money Transfer or MoneyGram Money Transfers. (If the engine is for a specific purpose and parts must be special ordered, full payment will be required right after your order is placed or your debit/credit card will be charged for the full amount or as a deposit.) Or you can pay A-1 Miller's through PayPal. My PayPal account name is my email address, and be sure to mention in PayPal a description of what the payment is for. If sending a money order or cashier's check, please include a note in the envelope with your name, complete mailing address, phone number and a description of what the payment is for. My mailing address and phone number are below Ê. And we will ship your rebuilt engine/parts to you as soon as we receive your payment.
To ship a transaxle, this is easier. They don't require an enclosed crate. Just place the transaxle on the center of a shipping pallet (of the appropriate size) and stretch wrap (use low-cost ratchet nylon tie-downs) to securely fasten it to the pallet. Use at least 6 layers of stretch wrap or several tie-downs. This should work really well. The shipping weight of a Cub Cadet garden tractor cast iron case transaxle when strapped to a wooden pallet is approximately 215 lbs. [Return To Previous Paragraph, Section or Website]

I'll consider it. And remember - Perfection takes time. If it's worth having,
it's worth waiting for. It'll be money well spent. Contact
information below.
Quality-Built and Nice-Appearing Garden Tractor & Mini Rod Self-Propelled Tractor Pulling Sleds (Weight Transfer Machines) For Sale - (Updated 8/17/24) [Top of Page]
Sleds will be built as orders are placed. A minimum 50% deposit
is required for all sled purchases. Buyer/purchaser can test sled with their
pulling tractors or vehicles on our 200 ft. dirt track, and then can tow
it on the road (like a trailer) or haul it on a large, sturdy trailer. Sleds
are designed with style and made beautiful to admire, and painted metallic
or color of your choice. Also, sleds are designed to start easy, pull smoothly
and sure to stop with grouser bar. They will also have a safety release lever
up front so when the weight box tops out and trips it, it will automatically
disengage the clutch to prevent major damage to the drive mechanism for the
weight box. And it will have another safety release lever at the rear in
case the clutch (for the weight box) is engaged when backing up the sled.
The self-propelled sleds will have a variable speed mechanical drive system
with hydraulics to lower the two front steering wheels/tires, and the bigger
sled will use hydraulics to bring the weight box back to its starting position.
By the way - the self-propelled garden tractor pulling sled that I built
in 1995 (and sold in 2021) is such an excellent design, I realized later
that I made something very special when other people copied it. It's still
in use today; click or tap photo of it to the right for a larger view.
Small size, pull-back
(non-motorized) sled with open cabin and cooling fan, comfortable swivel
seat and controls within easy reach for operator. For use with 1,050 lb.
garden pulling tractors and up to 1,500 lb. small wheel (26-12.00x12 tires)
mini rod pulling tractors. Length of sled: 12 ft. Total weight of sled fully
loaded with weights: approximately 4,000 lb. $6,000.00 each.

For Kohler engine models K241,
M10, K301, M12, K321, 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
