merchandise, you can make the long drive to
A-1 Miller's shop to personally
drop off and/or pick up your carburetor, clutch assembly, engine parts, entire
engine, transaxle, transmission, entire garden tractor, etc. for rebuilding
and/or repairing, or to purchase parts. "The road to a friend's house (or

high quality parts and professional services.)
   Throttle
Stabilizer/Anti-Surge Springs. Lightweight spring connects between throttle
and governor levers to remove free play (looseness) in linkage connections
and reduce erratic engine behavior 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. A must for a generator,
welder or 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 lose traction (temporary jerk), resulting in a possible failed
pull. If a small hole isn't already present in each lever close to linkage
connection, may need to drill a small hole to install spring.

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.
|
 High Quality Inductive Small
Engine Tachometer/Hour Meter. A tachometer is required in setting the
correct RPMs (normally 3,200 or 3,600 maximum for small engines) of an engine
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. mounted to monitor

 High Quality Digital
Tachometer/Proximity Sensor Kits. A tachometer is required in setting
the correct RPMs (normally 3,200 or 3,600 maximum for small engines) of an
engine to prevent from over-revving and possible damage to the engine or
dangerous flywheel explosion. Choice of a
RED or
BLUE numeric display. Will work with
single- or twin-cylinder small engines or multi-cylinder automotive engines,
gas or diesel. The great thing about this type of tachometer is it needs
no setup. It displays accurate RPMs as soon as the engine cranks over to
start. Displays up to 9,999 RPM. Very accurate. Tachometer returns to zero
[0000] when engine is shut down. Operates totally independent of the ignition
system. Can be used for lawn & garden equipment or competition pulling
engines. Designed to be permanently mounted to monitor engine RPM at all
times. Tachometer can be in-dash or panel-mounted. This precision digital
tachometer operates with external power and on the same principle as my
flywheel- or
crank-trigger ignition systems with a proximity sensor to detect the
target, which can be a small ferrous steel screw or pin, or magnet in a rotating
disc on the crankshaft or on/in flywheel. A sturdy steel or aluminum bracket
will need to be fabricated by customer to mount the sensor in close proximity
of the detector/trigger target. Set air gap/clearance at .010"-.188". Tachometer
works with 8-24 volts DC, proximity sensor works with 6-36 volts DC. Dimensions
for mounting hole for tachometer: 3" wide x 1-17/32" wide. Tachometer measures
1" in depth. Dimensions of proximity sensor: 15/32" diameter x 1-3/8" thread
length. Wiring Instructions: #1 wire on tachometer connects to brown wire
on proximity sensor and ignition switch (12 volt power), #2 wire on tachometer
connects to blue wire on proximity sensor and engine/chassis ground (battery
negative (–) post), and #5 wire on tachometer connects to black wire
on (either) proximity sensor. Wires #3 and #4 connects to nothing. Wiring
is the same for the hall effect and inductive proximity sensors. Some proximity
sensors have an LED (Light Emitting Diode) on the rear of unit. If the proximity
sensor is wired incorrectly, the LED will illuminate within the target.
Click or tap here for YouTube videos to see how well this
tachometer works. Cannot be wired in conjunction with the Dynatek Dyna
S or PerTronix Ignitor ignition modules. This tachometer must be wired separately
or wiring can be integrated with my crank-trigger ignition system that use
a proximity sensor.

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 RPMs.
Many people are not aware of this small, thin 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: Due to high RPM and pressure of
the governor gear upon engine start-up, before installing, lubricate the
stub shaft and thrust washer with motor oil, automotive chassis lube or wheel
bearing grease to prevent the governor gear from wearing until the crankcase
oil reaches these areas.

   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 the new/replacement bushing, apply clean
motor oil, gear oil or lubricating grease on the shaft for less wear to the
bushing, seal and shaft. An ingenious and innovative concept by Brian Miller,
because nobody else advertise this type of product or service.

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. |
| NOTE: Complete engine rebuild kits are available, but a kit will cost more than if the parts were purchased separately.

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 clean motor oil, gear oil or lubricating grease or on crank journal
before installing rod. This will better protect the parts until crankcase
oil reaches them. IMPORTANT: Click

 STD size, .010", .020"
or .030" (hard to find now) undersize Replaceable Tri-Metal (Lead
Alloy/Copper/Steel) Bearing
Inserts in Connecting Rods for Kohler engine models K241/M10, K301/M12,
K321/M14, K341/M16, K361 M20 and MV20. 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 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.
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 I 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/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.) I 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 I machine a rod for installation of bearing inserts, I use a metal "plug" alignment tool that I 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, I 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, I 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, I 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. Bigger balls rotate freer and run
cooler, which create less rolling resistance and friction than 12 ball bearings
with smaller balls. (It's just like small tires on a 4x4 or 4WD truck/vehicle
versus big tires - the bigger tires will roll with less resistance, especially
over rough terrain.) 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. 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.

 Valves for Kohler
engine models KT90/KT91. Head diameter: 15/16".
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.
Intake Valves for Kohler engine models K141, K160/K161 and K181/M8. Dimensions: head diameter: 1-3/8"; overall length: 4.065"; stem diameter: .309"; 45º face angle.

| Valve Guides FYI
-(FYI - All valve guides are made of either cast iron or bronze,
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 Section, Paragraph
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 &
handling. |
|
 Valve
Guide Removal and Installation Tool for use with virtually all flathead
block Kohler 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 to drive out the old guide into the valve
spring chamber and use the same hammer to install the new guide from inside
the valve pocket. Install new guides until flush with the port. Tool can
be used for OEM Kohler and aftermarket offset valve guides. Dimensions: .300"
pilot x 1/2" diameter x 5" overall length.
|
|
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 clean motor oil,
gear oil or lubricating 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.

OEM, Performance, High-Performance Camshafts, Valve Springs and Retainers, Rotators and Keepers
 New-Style One-Piece Camshafts.
Fits Kohler engine models K141, K160/K161, K181 and Magnum M8. With ground
points lobe and ACR. IMPORTANT: To prevent seizing of the camshaft when
the engine is ran for the first time, apply clean motor oil, gear oil or
lubricating grease on cam pin before installing cam. 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 K141, K160 and K161 cams can't be used in the K181 engine
due to its longer stroke. ACR = automatic compression release. FYI: Being
the automatic compression release (ACR) [hair-like] spring (part number 47
089 01-S) is no longer available from Kohler or in aftermarket, if yours
places little or weak pressure against the flyweights, it can be re-bent
to its original shape to place sufficient tension against the flyweights.
I do this all the time and it works great. It's became regular practice with
me. OEM Kohler part #'s 41 010 05-S.
Camshafts. Fits Kohler Magnum engine model M8, can also be used in the K-series K141, K160/K161, K181 engines with solid state ignition. No points lobe. With 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.

High performance camshafts for a Kohler K181 or M8 engine are available from Vogel Manufacturing Co. at: http://www.vogelmanufacturing.com. |
New-Style, One-Piece Camshafts. Fits Kohler K-series or Magnum engine models
K241/M10, K301/M12, K321/M14 or K341/M16. New-style, one-piece K-series camshafts
with ACR. Can be used in a K-series engine as an upgrade from the older two-piece
camshaft. 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 Engines
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, I 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. I have to do this to every reground cam I 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 I have, the points lobe is slightly worn. (It's hard to find a good used, 100% unworn cam nowadays.) I 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.

High Performance Camshaft for Hot-Stock and Stock-Altered Kohler Competition Pulling Engines
|
| 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.

and K582. Use only with long (1-3/4") OEM Kohler or the medium-, or
high-performance valve springs above È.
May cause lifter chatter, valve float and engine misfire if used with the
short (1-9/16") valve spring. For 5/16" diameter valve stems. Accepts 7º
keepers/locks/collets listed below
Ê. .998" outside diameter. Made of
lightweight heat-treated, hardened stamped steel.

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

AQS (Quiet Line) engine models K241, K301, K321, K341, K361 and various Magnum
engine models M10, M12, M14 and M16. Replace deteriorated and crumbly filter
to prevent oil loss. NOTE: This "filter" is actually an oil trap. It traps
and suspends oil droplets and prevents oil vapors from exiting 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

K301/M12, K321/M14, K341/M16 and K361 when converting crankcase breather
to open atmospheric vent. Plug prevents dust and dirt from entering the engine
through the air cleaner, resulting in excessive engine wear, which will lead
to 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.

Mill cylinder head approximately .050". Remove prominent/raised gasket mating
surface from head to increase compression ratio for the 10-16hp flathead,
K-series or Magnum single cylinder engines only. $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.
Professionally weld up burned-out area in small engine cylinder head, resurface on a wide sanding belt to remove warpage and restore flatness, and redrill bolt hole, if needed. NOTE - As long as there's no cracks in the head, it can be successfully welded up, resurfaced, and the bolt hole redrilled. IMPORTANT - Causes of a burn-out are: 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 RPMs; the adjustable high speed air/fuel mixture screw is set too lean; or 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 is put back into service. $75.00 for welding and labor, plus return shipping & handling.

Kohler Engine Model K361 Cylinder Head Repairs. 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 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.
FYI - I found that the Kohler K361 18hp OHV cylinder head use the longer 1-3/4" (uncompressed length) valve springs with rotators, the same spring that certain K241, K301 and K321 use with a stamped retainer. And of course, certain K241, K301, K321, and all K341 use the shorter 1-9/16" spring with a rotator. The official Kohler parts manual says the K361 use the shorter 1-9/16" springs (with rotators), but apparently, it's wrong. It uses the longer 1-3/4" springs (with rotators). On all of the K361 engines that I've rebuilt, with the 1-3/4" springs and rotators installed, there is no coil bind. This is when the coils of the spring make contact with each other at full 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 higher RPM and lacked sufficient power. He said he purchased the tractor used (with the same engine). So I checked the valve springs, and sure enough, it had the shorter ones (with rotators). Apparently, somebody (maybe the previous owner) worked on the cylinder head before, and for some reason, he installed the shorter valve springs. My customer was lucky it didn't drop a valve. That would've been a nightmare! But anyway, I installed a set of the longer 1-3/4" valve springs (with rotators). The valves felt stiffer when I pushed down on them with my hand, too. - Brian Miller |

for fastening of sheet metal all in good condition.
Click or tap here for cylinder
head bolt torque specs.
 2nd Generation Cylinder Head
for Kohler K-series and Magnum engine models K241/M10 and K301/M12. Can also
be used on the early K321 engines with the small (1-1/8") exhaust valve.
Spark plug located in middle of combustion chamber. Due to the location of
the spark plug, this head is not designed for use on a K-series AQS (Quiet
Line) engine. Cleaned and resurfaced on a
wide sanding belt or large diameter disc sander to remove
warpage and restore flatness. Cooling fins, spark plug threads and bolt holes
for fastening of sheet metal all in good condition.

 3rd Generation Cylinder Head.
Fits Kohler K-series and Magnum engine models K241/M10, K301/M12 and K321/M14.
Spark plug located in middle of combustion chamber. Due to the location of
the spark plug, this head is not designed for use on a K-series AQS (Quiet
Line) engine. Cleaned and resurfaced on a
wide sanding belt or large diameter disc sander to remove
warpage and restore flatness. Cooling fins, spark plug threads and bolt holes
for fastening of sheet metal all in good condition. Requires 1-1/2"
length head bolts. Click
or tap here for cylinder head bolt torque specs.
 4th Generation Cylinder Head.
Fits Kohler K-series and Magnum engine models K241/M10, K301/M12 and K321/M14.
Spark plug located over exhaust valve. Mostly used on the K-series AQS (Quiet
Line) engines. Cleaned and resurfaced on a
wide sanding belt or large diameter disc sander to remove
warpage and restore flatness. Cooling fins, spark plug threads and bolt holes
for fastening of sheet metal all in good condition. Each requires
1-1/2" length head bolts. Click
or tap here for cylinder head bolt torque specs. FYI - Dyno tests
have proven that this is the best cylinder head to use for a Stock or Hot
Stock competition pulling engine because it has the spark plug located over
the exhaust valve, which retains the majority of the heat in one area for
better combustion of the fuel so the engine will produce more power. This
is why Kohler made this type of head because dyno tests have proven that
it works better than their previous-designed heads.
 16hp Cylinder Head. Fits Kohler
K-series and Magnum engine models K341/M16. Cleaned and resurfaced on a
wide sanding belt or large diameter disc sander to remove
warpage and restore flatness. Cooling fins, spark plug threads and bolt holes

 High Quality Cylinder Head
Bolts and Flat Washers. Fits Kohler engine models K141, K160/K161, K181 and
M8. OEM Kohler head bolts can be reused multiple times. They will not stretch
overtime and are not
"torque to yield." But replace bolts with eroded, rusted
heads to prevent socket from slipping so bolt will torque down correctly.
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.
Click or tap here for cylinder
head bolt torque specs.
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. I 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 intelligence.)

Magnetic Oil Drain Plugs, Oil Filter Adapter, Oil Filters and OEM Kohler Cast Aluminum and Cast Iron Oil Pans - Please contact me if you're interested in any of these parts or services. | [Top of Page]
Magnetic Oil Drain Plugs with Tapered Threads and Square Head. 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 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
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. Oil filter not included with kit;
order separately 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 newer) 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.
|
    Each oil filter listed below provides superior filtration
for less internal engine wear, and fits virtually all OHV single cylinder
and V-twin Briggs & Stratton, Kawasaki, Kohler, and opposing twin cylinder
Kohler engines. Including Kohler engine models CH11, CH12.5, CH13, CH14,

| Crankshaft Repairs - This includes Briggs & Stratton, Kohler,
Tecumseh, etc.
Regrind journal (crank pin) to next undersize. NOTE: Kohler crankshafts can be reground to .030" undersize and still be safe to use with matching undersized replaceable bearing inserts installed in the connecting rod. And all crankshafts, rather if they're automotive or small engine, are checked for straightness before regrinding. If they're bent or twisted, sometimes they can be straightened. I also do offset crankshaft regrinding to increase the length of the stroke at no extra charge. NOTE: Once installed and in operation, there is no warranty or guarantee of any kind on crankshaft regrinds.
"Round Up" Rod Journal(s) and Resize Connecting Rods. The service is for most makes and models of 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, I 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 .
Repair broken off 5/8" stud on flywheel end of crankshaft. Center drill and cut threads for a 3/8" diameter grade 8 bolt in the end of crankshaft.
Drill hole and cut 7/16-20 UNF (fine thread) threads in the PTO end of the crankshaft for bolt and flat washer.

Solid Motor Mounts for Cub Cadet "Quiet Line"
Tractors - Replace Deteriorated "ISO" Rubber Motor Mounts with a Set of Machined
Solid Steel Motor Mounts! An original, ingenious, innovative
concept invention by Brian Miller, because I was the one who originally thought
of, promoted and advertised the use of this product. Please accept
no copycat products of this kind. (But I do appreciate them acknowledging
my intelligence.)
Details include:
Solid motor mounts are an
alternative to replacing deteriorated OEM "ISO" rubber engine mounts, which
is usually associated with a damaged "flexible" 3-pin clutch drive plate
and damaged clutch components. These fit IH Cub Cadet "Quiet Line" garden
tractor models 482, 800, 1000, 1100, 1200, 1204, 1210, 1211, 1250, 1282,
1340, 1450 and 1650. If the engine in your tractor is mounted on angled cradles
with rubber mounts between the cradles and tractor frame, then these are
what your tractor need.
Direct replacement for OEM
ISO-rubber mounts with no modifications to the tractor whatsoever. The solid
motor mounts install between the engine mounting cradles and tractor frame.
A thick flat washer fastens on top of the cradles. Torque the bolts at 35
ft. lb. Can be easily removed if rubber mounts are desired instead.
(Added
3/17/20) OEM Cub Cadet Engine Rubber ISO-Mount Kit. Replace deteriorated
rubber ISO-mounts to lessen chances of clutch drive plate breakage and so
less wear will occur to the clutch assembly. Designed for IH-built Cub Cadet
"Quiet Line" models 800, 1000 and 1200, including models 1250, 1450 and 1650
with a hydrostatic disconnect attachment. All of these models have the engine
mounted on rails with ISO rubber mounts. These rubber mounts can also be
adapted for use on many other makes and models of small engine equipment
to reduce engine vibration throughout the frame.

| Information About My Engine Rebuilding Service -
Small engine technology has changed a lot since the Kohler K-series and Magnum engines were made. I can rebuild your lawn and garden engine (or competition pulling engine) with new technological parts so it'll produce more power and last longer than the factory anticipated. I also build engines from scratch and rebuild customer's complete engines from factory stock, to 4,000± RPM governed, to wide open throttle Hot-Stock and Stock-Altered competition pulling engines. I can build a quality, competition engine for you, or rebuild your engine however you want. Just tell A-1 Miller's know how you're going to use your tractor or equipment and I'll build your engine to suit your needs. And if it's required in your club's rules or not, ALWAYS install a safety shield made of adequate thickness and material for each side of the engine fastened to the tractor frame securely in case of connecting rod failure (Murphy's Law), so an innocent bystander or spectator won't be injured or killed from high-speed projected metal shrapnel. I don't have any rebuilt Kohler short blocks or engines in stock. And if I 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, I 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 I use the best parts, use caution on choosing the right motor oil to use in your engine. Because the government (tree huggers/Sierra club) is requiring oil companies to lessen the amount of zinc in their motor oils to reduce pollution. Zinc provides a protective coating on internal engine parts and prevents metal to metal contact for proper break-in and it helps the parts last longer. 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 Build Estimate -
I am very meticulous in how I rebuild and build engines. If you would like
to have A-1 Miller's build, rebuild or build-up your engine, I will need
a detailed list of exactly what you want done to your engine or a copy of
your club's pulling rules regarding the engine requirements before I can
give you an estimate on the cost. And if you (the customer), change
your mind of how you want the engine built or rebuilt in the middle of a
build, I will need to know ahead of time and I will need the changes in writing
so I can make the necessary changes to the engine. Otherwise, this will effect
how well the engine performs on the track, and it would make me, as a
professional engine builder, look bad. It's not a good thing to be afraid
that something bad may happen to an engine. Having confidence in an engine
makes ya feel good, but having confidence in your engine builder makes ya
feel better. I do not build illegal competition pulling engines that do not conform to your club's rules! But there are certain other engine builders that offer new pulling engines for sale. BUT, 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." Therefore, you may receive an engine that do not conform to your club's rules, and it may be built "above the rules". Meaning it's not legal within your club's rules and is illegal to run in the class you plan to pull it in (cheater engine). Or, the engine in question may be built "below the rules" so it's less competitive as an engine that is built legally to the max according to the rules. But I'll build your engine or an engine for you so it'll produce the maximum horsepower and torque in accordance with your club's rules, not less than what the rules allow. I 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 I couldn't repair, rebuild or build-up for more power! Whenever I rebuild or build-up an engine, and if you would like to do so, I do whatever it takes so it'll produce the factory-rated horsepower or the maximum horsepower and torque, and last a long time. I go beyond what the repair manual says to do. I can get all the parts needed, too. I 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. 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 I wouldn't want to do a rush job. I also have to depend on other local machine shops to perform various machine work and balance rotating engine parts. All this takes time. I 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 I offer. I 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, I don't like to rush on my customer's repair jobs. I'm very particular about my work, especially my engine builds. I 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. I 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. I can purchase new parts from Kohler if they're still available, but that would be cost-prohibitive. I try to keep my engine builds at reasonable prices. - Brian Miller Things that we perform to a 10-16hp Kohler engine to greatly improve engine performance:
All of my customer's competition pulling engine builds are strictly confidential! This means the people you pull against will not know what goes into your engine. |

A-1 Miller's Kohler Competition Pulling Engine Building | [Top of Page]
The below Ê are high output engines, built and designed for competition pulling only, not general lawn and garden use. No charging system included. 10hp (K241), 12hp (K301), 14hp (K321) or 16hp (K341) Kohler engines built by Brian Miller.
The "Built to the Max" Stock class engines runs at 4,000± governed RPM;
has a 9-1/2" cast flywheel with majority of fins removed then dynamically
and precision spin-balanced; high torque upper mount gear starter (mounting
bolts are below the starter motor); performance valve job with stock size
valves; A-1 Miller's reground/torque cam; medium performance valve springs;
#26 or #30 Kohler carburetor (depending on engine size) bored-out, reworked
and set up for gas; enlarged ports and polished (intake port made larger
only if it is smaller in diameter than the carburetor throttle bore); 2nd
or 3rd generation cylinder head milled .050"; connecting rod bored .020"
offset for piston pop out with bearing inserts. Also
included are: flywheel shroud (not chrome plated), cast iron or aluminum
oil pan, bolt-on header pipe and conventional Kohler point ignition system
installed with ignition timing preset. And being there is no oil filter on
Kohler cast iron block engines, an oil drain plug with a very strong
rare earth/neodymium magnet, or a very strong
rare earth/neodymium magnet will be glued to the inside bottom of the oil
pan or engine base to attract and remove
ferrous
metallic wear fragments from the motor oil to clean the oil so the engine
will last much longer. Because some of the ferrous metal wear fragments settle
to the bottom of the oil pan or engine block and do not drain out with the
oil when performing an oil change, even when the oil is hot. Remember
- Metal flake looks good in paint, not in oil.
A-1 Miller's rebuilt engines will be painted with high quality gloss black, unless the customer specifies a different color or no paint at all. When you receive the engine, install it 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 controls, and the engine will be ready to start. Carburetor adjustments will be initially preset, but due to the altitude level, barometric pressure and air temperature, final idle speed, idle air/fuel mixture and high speed air/fuel mixture adjustments may need to be made after the engine is started and warmed up. It'll have no charging system. Use a remote battery charger to recharge the battery before each pulling event. 4,000 RPM "Built to the Max" Stock-Appearing Competition Pulling Engines below - built for competition pulling only and to your pulling association/club's sanctioning rules. In addition to all the essentials, prices below include a heavy (ring gear) steel flywheel and new high torque gear starter motor (Kohler style). Custom crank trigger ignition or $100 to build a sturdy wooden shipping crate and shipping & handling is extra charge. Or you can visit A-1 Miller's shop to drop off and pick up your engine(s) to save on crating and shipping charges. Horsepower/torque and price depends on how the engine is built.

Competition Pulling Engine Freshening Service Ê This service is for pulling engines only that have been previously built, and needs the basic parts and labor to revive the power. It is not a complete engine rebuild. A typical pulling engine will last an average of 25 pulls or 3 years of use. After that, the piston rings become worn, and the engine may lose power when under load and puff gray/blue smoke out the exhaust and/or crankcase breather vent. When this happens, it's time for a freshening job. If interested, we will need an updated copy of your association/club's engine rules so when the engine is freshened, it will be legal in its class, but still competitive. Click or tap here for proper break-in (wear-in) oils and procedure for rebuilt engines. Add $110.00 - $152.00 for installation of A-1 Miller's custom crank trigger or flywheel triggered electronic ignition system. (For competition pulling only.) A 50% deposit may be required on certain engine refresh jobs. Deposit is non-refundable if labor and machine work is invested in the engine, and parts are purchased for the engine. Remaining balance of total amount is due upon completion of engine refresh. [Top of Page] Freshen Stock "Built to the Max" 10-16hp 4,000± RPM governed Kohler competition pulling engine.

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 RPMs 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 RPMs, 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 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 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 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 I built for them run better every time they pull them. I remember a few years ago when I performed a valve job on my truck engine. It ran good and produced plenty of power, but I noticed after about 1,000 or so miles, it produced a little more power. I 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 in a Sturdy Wooden Crate - [Return To Previous Paragraph, Section or Website]
If you bring an engine to
A-1 Miller's in person, place it in an old automotive tire to keep it from
moving around during transportation. And please let A-1 Miller's know first
so I can expect your arrival. But if you decide to ship your engine to me,
I don't need everything on it. Just the parts that can wear and need rebuilding
or reconditioning, such as the gear starter, cylinder head(s), crankcase
breather assembly, fuel pump and carburetor. I need the oil pan on it too,
to prevent any dust and dirt from entering the crankcase after the rebuild.
Please remove all sheet metal and PTO clutch/pulley, too. I'll need the flywheel
on the engine so I can set the ignition timing. Please send or bring your
engine when you're ready to the address below
Ê. By the way - I have a heavy duty 2-jaw
gear puller that we use with a large c-clamp to remove the mechanical PTO
clutch/pulley from Cub Cadet engines. But sometimes these clutch/pulleys
will not remove without breaking. I do all I can to try to prevent this from
happening, but when they do break, I have no choice but to install a rebuilt
PTO clutch/pulley assembly. I also made a special puller tool to remove the
large stamped steel PTO pulley from the crankshaft without damage.
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 never 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. If you're the kind of person who don't trust delivery/shipping companies (mis)handling your [irreplaceable] high-dollar and fragile merchandise, you can make the long drive to A-1 Miller's shop to personally drop off and/or pick up your engine(s), transaxle, tractor, etc., for modifying, rebuilding or repairs.
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 I 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 I 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, I 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 I will ship your rebuilt engine/parts to you as soon as I 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 cast iron case transaxle when strapped to a wooden pallet is approximately 215 lbs. [Return To Previous Paragraph, Section or Website]
A-1 Miller's Computerized Stuska Water Brake Engine Dynamometer (Dyno) Service with DPM Data Logger Software to Test Horsepower and Torque! | [Top of Page]
For performance testing of 10-16hp
single cylinder Kohler stock or competition pulling engines at speeds up
to 12,000 RPM. 100% accurate, customers can rent dyno time, fine tune and
make adjustments or changes to their engines to gain maximum horsepower and
torque, and print-out the results so their tractor(s) will be truly competitive
on the track. With an engine dyno, the puller can adjust their engine to
get maximum horsepower and torque, and gear their tractor appropriately to
have an advantage over the competition. NOTE: A fresh-built engine may
not produce full power until it's broke-in. This is when the valves wear-in
with the seats to completely seal in the compression. The rings will likely
hold the compression, but the valves may leak slightly until they wear into
the seats. This is normal for all engines and may take several hours or pulls
to happen, then the valves will be able to hold full compression. Lots of
pullers tell A-1 Miller's after I've built their engines that it seems to
pull stronger every time they pull it.
Engine Dyno Rental Fee: $50.00 per hour run time from the moment the engine is started. No setup fee for Cub Cadet engines with a 3- or 6-pin/stud clutch driver. An adapter may need to be needed or fabricated for other makes and models of engines. Only engines with the narrow base oil pan can be tested. Engines with the wide base (tall) oil pan cannot be tested at this time. [Return to Previous Section, Paragraph or Website]

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 (.324"), 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), reworked and undercut stock size valves for more airflow, 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

Perform Professional Valve Job Only on opposed (flathead)
twin cylinder Kohler KT-series and Magnum engine models KT17, KT17 Series
II, KT19, KT19 Series II, 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 smooth without stalling, and it will have
full power at top governed speed. 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 sanding belt to remove 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 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 crankcase) and valves can be shipped in a USPS Large Flat Rate
Box. Use two boxes - place one box inside the another to double the strength,
and use rigid packing material to prevent the cooling fins from breaking
off by making contact with each cylinder.
Regrind your [45º] intake
valve at 30º angle and undercut head for more airflow. $17.00
labor each, plus return shipping & handling.
