 7/32"-1/4" Governor Cross
Shafts. Fits Kohler engine models K141, K160/K161, K181 and M8. New shaft
includes thrust washer. Steel spacer for this shaft (part # 25 112 17-S)
no longer available from Kohler. The lever on these rarely break off. NOTE:
Before installing, apply oil or grease on shaft for smooth governor action
and less wear to shaft and/or bushing. OEM Kohler part # 230540-S.
|
   Kohler Governor
Cross Shaft Bushings with Rubber Lip Oil Seal or Neoprene Rubber O-Ring
Installed. Seal or O-ring fits snug in bushing and on shaft, and has
no effect with operation of governor function whatsoever. WHY THIS IS
IMPORTANT: On single cylinder Kohler engines, vacuum within the crankcase
created by the upward stroke of the piston draws in outside air, along with
a small amount of dust, dirt/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/debris of this repeated reciprocating action 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: When removing
the old bushing, use caution not to drop the governor cross shaft down inside
the crankcase! (Complete disassembly of the engine will be required if this
happens.) And before installing any new oil seal or rubber O-ring,
always apply oil or grease inside seal or O-ring and on shaft to keep
seal or O-ring lubricated and cool until crankcase oil can reach it. With
no prior lubrication, the dry rubber will wear away from friction, possibly
causing an oil leak. An ingenious and innovative concept by Brian Miller,
because nobody else advertise this type of product or service.

 Nylon Governor Gear Assemblies.
Designed for general lawn and garden work. Also suitable for a 4,000±
RPM competition pulling engine. Fits Kohler engine models K141, K160/K161,
K181, M8, K241, M10, K301, M12, K321, M14, K341, M16, K361, KT17 (first design),
KT17 Series II, KT19 (first design), KT19 Series II, KT21, MV16, M18, MV18,
M20 and MV20. IMPORTANT: Apply oil or grease on thrust washer and stub
shaft to prevent wear or damage to governor gear assembly upon engine startup
until the crankcase oil reaches these areas.
|
Thrust
Washers for Governor Gear Assemblies. 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 thrust washer and
stub shaft to prevent wear or damage to governor gear assembly upon engine
startup.

   Throttle
Stabilizer/Anti-Surge Springs. Install either of these lightweight springs
connect 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 will cause the
rear tires to temporary
lose traction (jerk), resulting in a possible shorter distance pull. An
ingenious and innovative concept by Brian Miller, because nobody else advertise
this type of product for a governed pulling engine.

 High Quality Inductive
Handheld Small Engine Wireless Tachometer. A tachometer is required in
setting the correct RPM (normally 3,200 or 3,600 maximum for small engines)
of an engine to prevent from over-revving and possible damage to the engine
or dangerous flywheel explosion. Very accurate. For gas/spark ignite engines
only. Works with magneto and battery-powered ignition systems. Very accurate.
This handheld analog tachometer works great for checking/setting the RPM
on various small engines in the shop, and/or for checking/setting the RPM
[tech] on stock governed competition pulling engines. Hold sensor (antenna)
close to spark plug wire for reading. Operates off a self-contained replaceable
9 volt battery. Has built-in battery voltage check. Reads up to 5,000 RPM
on the low scale, and 15,000 RPM on the high scale.
|
 Inductive Small Engine
Tachometer/Hour Meter with replaceable battery. A tachometer is required
in setting the maximum speed of a small engine, which is normally 3,200 or
3,600 RPM, for small engines to prevent over-revving and possible damage
to the engine or dangerous flywheel explosion. Very accurate. Can be hand-held
to temporarily set engine RPM or can be surface-mounted and secured with
two screws to monitor engine RPM at all times. Large 3/8 inch LCD display.
Works with all spark ignition engines by selecting engine type by programming
S1 and S2 buttons. Works with magneto and battery-powered ignition systems.
If tachometer does not turn on automatically as soon as engine starts,
press and hold the two buttons at the same time. Instructions included.
Reads up to 99,999 RPM. Hour meter reads up to 9999:59 hours/minutes.
Programmable maintenance hour setting with service icon, a service reminder
when to change oil or other maintenance. Can be manually reset to Zero hours.
Easy installation: Single wire wraps around spark plug wire and secured with
two supplied nylon zip-ties. No wire terminal connections required. Weatherproof
construction. Requires CR2450 battery. Dimensions: 2" wide x 1-3/4" depth

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

because there's more "wear area" around them due to the flat area.
|
| 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.

piston pop-out at no extra charge.
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 we 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.) we 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 we 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". |
 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 12 ball 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.

Exhaust Valve. Fits Kohler engine models KT90/KT91. OEM Kohler part # 220009-S. $45.05 each, plus shipping & handling. NOTE: Before lapping in valves, it's best to have the valve seats recut or reground so they'll be in correct alignment with the centerline of the valve guides. Otherwise, the valves may not make a full 360º contact with the seats, resulting in leakage and the engine will lose compression, be hard to start, lose power and possibly make a popping sound through the carburetor or out the exhaust at idle speed. And be sure to set the clearances correctly, too. And if the end of the valve stem is accidentally ground too short, it can be made long again by building up welding with a MIG or TIG welder, then ground to the correct valve clearance.

| 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.
[Return To Previous Paragraph, Section
or Website]
NOTE: The alternative to installing new replacement OEM-type valve guides is to have the old [worn] guides reamed for installation of thin-wall bronze sleeves/liners (bushings), which can be installed by a reputable automotive machine shop. Bronze valve guide sleeves/liners are a low-cost alternative to replacing the entire guide in most engines. Bronze also last longer than cast iron guides because bronze is harder material and it retains more oil for better lubrication of the valve stem.
 High Quality, High Speed Steel
5/16" (.3125") Chucking Reamer. Use to clean carbon deposits from used valve
guides or enlarge new guides for a 5/16" valve stem in flathead 7hp+ B&S,
Kohler, 8hp+ Tecumseh, etc. engines. $15.00 each, plus shipping &

 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 from inside the valve pocket. When installing the
new guide, be sure to hammer straight down in alignment with the guide 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. An ingenious and innovative concept by Brian
Miller. Please accept no advertised copycat products of this kind. (But I
do appreciate them acknowledging my ingenuity and intelligence.)

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.

New-Style, One-Piece, Plain, Ordinary OEM Camshafts with Automatic Compression
Release (ACR). 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. When reusing lifters, roughen lifter faces with
600 grit sandpaper to produce a new wear pattern and so the lifters will
rotate slightly with every lift to prevent wear to the cam lobes. And the
lobes on the used cams have not been reground for performance.
|
Professionally Reground 4,000± RPM Performance Torque Cam for Kohler EnginesFYI - 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.

 OEM Kohler Stamped Steel
Valve Spring Isolator. Prevents engine operating heat from collapsing or
weakening valve springs. For general yard and garden engines. Not required
for competition pulling engines. Fits Kohler K-series and Magnum engine models
K141, K160/K161, K181, M8, K241, M10, K301, M12, K321, M14, K341, M16, K361,

guides. OEM Kohler part # 235011-S.
|
| 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.
|
 OEM Kohler Stamped Steel

the crankcase at higher RPM, then allows the oil to drain back down into
the crankcase when the engine is at idle or turned off. (It's too coarse
to be a filter of any kind.) Not included in
aftermarket engine gasket set. Fills entire
area of breather plate. To be used with crankcase breather cover with PCV
breather vent hose/tube and external oil control baffle shield and reed stop
part # 270146-S (listed below). Dimensions: Approximately (±) 3" width

air cleaner on Kohler AQS (Quiet Line) and Magnum engine models K241, M10,
K301, M12, K321, M14, K341, M16 and K361 when converting from positive crankcase
ventilation (PCV) system to open atmospheric venting. Plug prevents dust
and dirt from entering the engine through the base of the air cleaner, resulting
in excessive engine wear, which will lead to valve wear, smoking out the
exhaust and oil burning. When the plug is installed in the hole, it will
have a loose fit. Therefore, the locking tangs will need to be bent/flared
outward to secure it permanently in place.

| A-1 Miller's Professional Valve Repair Service
for Kohler Engine Model K361 Cylinder Head. [Top of
Page] 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). 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.
FYI - I have found that the Kohler K361 18hp OHV cylinder head use the longer 1-3/4" valve spring (uncompressed length; discontinued Kohler part # 235010-S) with rotators for both valves, the same spring that certain early K241, K301 and K321 engines use with the stamped retainer. And of course, certain later K241, K301, K321, and all K341 engines have the shorter 1-9/16" spring (uncompressed length; discontinued Kohler part # 235168-S) with the rotator. Anyway, the official Kohler parts manual says that the K361 use the shorter 1-9/16" springs (with rotators) for both valves, but apparently, it's wrong! It obviously requires the longer 1-3/4" springs (with rotators). And of all the K361 engines that I've rebuilt through the years, with the 1-3/4" springs and rotators installed, there is no coil bind. Coil bind is when the coils of the spring make contact with each other at maximum valve lift. I've had a customer send his K361 head to me for repairs, and when I spoke to him on the phone about his engine, he mentioned that the engine had always made a chattering/rattling sound at full governed speed and lacked sufficient power. So I checked the valve springs, and sure enough, it had the shorter 1-9/16" springs (with rotators). My customer was lucky it didn't drop a valve. That would've been a nightmare! So I installed a set of the longer 1-3/4" springs (with rotators). The valves felt stiffer when I pushed down on them with my hand, too. - Brian Miller |
 A-1 Miller's Professional
Repair Service - Resurface air-cooled small engine flathead or OHV cylinder
head on wide, flat
belt- or disc-sander/grinder to remove any warpage and
restore flatness for better sealing of head gasket and prevent possibility
of burning-out of [high dollar] head due to severe warpage. (Sanders are
not just for woodworking.) Includes deburring of sharp edge around combustion
chamber to prevent detonation or pre-ignition.
Click or tap here for cylinder
head bolt torque specs. $10.00 labor, plus return shipping &
handling.
NOTE - If it's repairable, please do not discard your cylinder head or other OEM Kohler parts. Most discontinued Kohler parts in good, usable condition are hard to find nowadays, and nothing works better than the original part(s) the engine was designed for. |
 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
combustion chamber to prevent detonation or pre-ignition.
Click or tap here for cylinder
head bolt torque specs. $25.00 labor each, plus return shipping
& handling.
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, please do not discard your cylinder head or other OEM Kohler parts. Most discontinued Kohler parts in good, usable condition are hard to find nowadays, and nothing works better than the original part(s) the engine was designed for.
A-1 Miller's Professional Repair Service - Drill out rusted-in/broken off [1/4"] bolt in cylinder head and retap threads for fastening of baffle shields (sheet metal) and/or brackets. No need to purchase another hard-to-find cylinder head that's in good condition. Also includes resurface head on a wide, flat belt- or disc-sander/grinder to remove any warpage and restore flatness. NOTE: Always apply anti-seize compound on threads of bolt before installing. $10.00 each labor, plus return shipping & handling.

5/16" diameter x 1-1/2" thread length grade 8 bolts and hardened washers.
NOTES: Clean the threads in the block with a 5/16-18 UNC plug hand tap
so the bolts will torque correctly. Then apply motor oil on the threads and
torque each bolt to 240 in. lbs. or 20 ft. lbs.
Liquid threadlocker is not necessary.

High Quality Aftermarket Single Cylinder Head Stud Kits. These studs can
be reused multiple times. They will not stretch overtime and are not
"torque to yield." Fits Kohler engine models K241, M10,
K301, M12, K321, M14, K341, M16 and K361 with an OEM or Billet Head. Each
kit includes 3/8" diameter x 2" or 2-3/4" length high quality heat-treated
studs, grade 8 nuts and hardened flat washers. We can also make the head
studs any length you want. 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. (Cast iron is weaker than hardened steel.) Also,
the flat washers goes under the nuts to distribute even pressure across head.
IMPORTANT: As with any threaded stud, apply
medium strength liquid threadlocker (Blue Loctite, Permatex
or equivalent) on threads that goes in the block to prevent stud from loosening.
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. Thread stud 3/4" into the block. Use a hardened
flat washer under nut to distribute load across 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. 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. An ingenious and innovative
concept by Brian Miller. Please accept no advertised copycat products of
this kind. (But I do appreciate them acknowledging my ingenuity and
intelligence.)

Oil Level Check and Drain Plugs with Tapered Threads and Square Head
listed below. A-1 Miller 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 engines.
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. The engine will last
much longer due to cleaner oil. Magnetic drain plugs are suitable for engines
with splash oil lubrication (no oil pump/filter). Remember - Metal flake

 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. Engine
or gears/bearings will last longer due to cleaner oil. 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. 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, M18,0 MV18, M20 and MV20. (Will not fit KT17 (first design)
or KT19 (first design) 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
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) with kit on model M18 engines
w/specification # 24532, after serial # 1835400002 (1988 and later) to block-off
the hole in the adapter body if the engine is not equipped with a low oil
shut-off sensor, oil pressure switch or oil pressure gauge.

  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
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.

Bronze valve guide sleeves/liners are an alternative to replacing the entire guide in Kohler engines. Bronze also last longer than Kohler's cast iron guides because bronze retains more oil for better lubrication of the valve stem. Install OEM-type [centered] cast iron valve guide or offset valve guide in single cylinder OEM Kohler block and ream for clearance of valve stem: $15.00 each labor only, plus return shipping with Fastenal or FedEx Ground. Price does not include guide.

Price does not include guide. Oversize valve MUST be used with an offset guide. |
 "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-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. NOTE: Once installed
and in operation, there is no warranty or guarantee of any kind on crankshaft
regrinds. An innovative concept by Brian Miller,
because nobody else advertise this service.
Crankshaft Regrinding - This service includes Briggs & Stratton, Kohler, Tecumseh, etc.
Repair damaged or broken off threaded stud on flywheel end of crankshaft with installation of 3/8" or 7/16" grade 8 UNF bolt. $50.00 each, plus return shipping & handling.

| Information Concerning A-1 Miller's Professional Engine Rebuilding,
Build-Ups and Building Services -
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 or equipment. Because Kohler engines are made specifically to fit a certain model of garden tractor 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 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 bore.) OEM 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 built from scratch
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 clubs' 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 - Being I'm the only person to read and respond to all my customer's emails (about 20 or so per day), take my customer's phone call orders (about 20-30 on a nice day with good weather), with customers stopping by my shop, repair and rebuild my customer's parts and engines in my shop, locate hard-to-find engine parts, order parts from my suppliers, process orders, package parts then mail customer's parts at my local Post Office, etc., it may take A-1 Miller's several months to rebuild an engine. It also takes time to perform precision machine work and manual workmanship on an engine rebuild, especially for a competition pulling engine, and we wouldn't want to do a rush job. we also have to depend on other local machine shops to perform various machine work and balance rotating engine parts. All this takes time. we tried hiring different people to help me in my shop, but it seems a lot of people don't fully understand about most of the parts and services that we offer. We never fired anyone. They all quit on me. So please keep this in mind if you decide to have A-1 Miller's rebuild/build up your engine. Also, we don't like to rush on my customer's repair jobs. I'm very particular about my work, especially my engine builds. We like to take my time to make sure that everything is right, the engine will run right, produce full power and last a long time. We appreciate for you understanding my situation. - Brian Miller 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. - Brian Miller 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. |
Below Ê are details and prices to rebuild your engine -
  Professional Repair or Rebuild Service for Briggs & Stratton
16, 18 and 20hp opposed twin cylinder aluminum block engine (horizontal or
vertical shaft) to OEM factory specifications @ 3,600 governed RPM for general
lawn and garden use, snow removal or mild competition pulling. Only high
quality machine work is performed and replacement parts are installed! All
baffle shields (sheet metal) will need to be removed before bringing or shipping
engine to A-1 Miller's. When shipping
an engine, it must be securely fastened inside a sturdy wooden crate.
IMPORTANT: Click or tap here for proper break-in
(wear-in) oils and procedure for rebuilt engines. NOTE: If your
engine doesn't smoke out the exhaust and burn oil, then chances are, all
it needs is a professional valve job performed. Then the engine should 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). We can do this instead
of rebuilding your engine. The price is $300.00 for all parts and
labor to perform the valve job, plus return shipping.

Break-In (Wear-In) Oils and Procedure for Ordinary
Rebuilt (Lawn and Garden) Engines -
First of all, full synthetic/organic motor oil will allow an engine to run cooler and last longer. But the rule of thumb for different types of motor oils are: Full synthetic motor oil is mainly for high performance/racing engines that operate at high RPM for a long time. Synthetic blend motor oil, which is a blend of about 50% organic and 50% petroleum, is for engines that occasionally operate at high RPM, but also operate at normal speeds. And conventional/petroleum motor oil is safe to use just for engines that operate at normal speeds at all times.
If the tractor is geared correctly, the pulling engines we 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 22º BTDC. And make sure the high speed air/fuel mixture screw is set so the engine runs smooth at high RPM. Also, if a high-output/performance ignition coil is used, it requires two standard capacity (Kohler) condensers/capacitors or one heavy duty, high capacity/performance condenser/capacitor. This is so the coil will produce more 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 (wear-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 (30º/31º or 45º/46º, respectively), the valve faces needs to wear into the seats to seal in the compression 100%. Wear-in will produce a 30½º or 45½º angle on both the matching valve face and seat. The harder material the valves are made of, the longer it takes for them to "seat" or wear-into the seats. Some pullers tell A-1 Miller's that the engines we built for them run better every time they pull them. We remember a few years ago when we performed a valve job on my truck engine. It ran good and produced plenty of power, but we noticed after about 1,000 or so miles, it produced a little more power. We realized that this is because the valve faces wore into the seats, forming a perfect seal. So again, a fresh-built pulling engine will not produce full power the first few times it's ran.

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 (573-256-0313 (shop) | 1-573-881-7229 (cell; text or when leaving a voice message, please speak slowly and clearly) 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 to keep
it from moving around during transportation. 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 shop to personally
purchase parts, or drop off and/or pick up your carburetor, clutch assembly,
engine parts, entire engine, transmission, transaxle, entire garden tractor,
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 later this year 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 during construction 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 Fastenal or 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 Fastenal or FedEx Ground shipping center for more details and to schedule a pickup or drop off the crated engine at your local Fastenal or FedEx Ground shipping center. Fastenal and FedEx Ground are 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. You can visit A-1 Miller's shop to drop off and pick up your engine(s) to save on crating and shipping charges.
Do not use a cardboard box alone
the ship a heavy engine! Crate it well and any other parts with it securely
so they 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]

For Kohler engine models K241,
M10, K301, M12, K321, M14, K341, M16 and K361. Suitable for a stock competition
pulling tractor or for heavy lawn and garden work. This particular cam profile
design provides 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 an 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
Ê; to prevent fuel spray out the carburetor
and lifter chatter), race-quality retainers (or the OEM Kohler stamped steel
retainers), 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

Repair loose valve seat with
a new BRONZE valve seat. FYI - A
replacement pressed-in steel valve seat will loosen, without a doubt,
after a short time in an aluminum cylinder head, even if it's professionally
installed. But a replacement pressed-in bronze seat will NOT loosen when
professionally installed because the "roughness" of bronze grips or adheres
to aluminum much better than the "slickness" of a steel seat. Plus, being
bronze is actually harder than cast iron, it will wear very little and hold
up to extreme heat, even for the exhaust side. $75.00 each for
parts and labor, plus return shipping & handing.
