rebuild kit
 

Has anyone here ever bought one of these kits ? Seems awful cheep just wondering about the quality.

I have a kit in my 128 engine and I have a kit for the 8hp motor that was in the 73 that belongs to my nephew. Now, I can't say as to how good it is, because I can't ever seem to get money or time to finish my 128 to get it started up, LOL. But, I had no issue with the parts other than the head gasket is crap. I just went up to the dealer and got a Kohler head gasket that has the fire ring around the cylinder area.

I put a kit from that seller in my 10 hp Kohler. It was the kit with piston, rings and gasket set. It seems to be working fine so far and all ring gaps and piston diameter were exactly where they should be.

Ok thanks. My engine id tag is long gone and I'm wondering if anyone can say for sure just what it is. So far I think it's a K321 14hp I just don't know if it's a D series or just what the D means ? My motor has a 3 1/2" bore and has breaker points.

i used this kit for 13 rebuilds ,over the last 10 years ,and never had a come back .no matter what you use if the engine is set up right by the manual you will be fine ,be sure you have a good machinist [mic] all parts .don,t bore any bigger than you need too .setting the right clearance is the key .hope this helps .David

my 16hp rod/piston/gasket set from ebay was fine. I thought the gaskets might be horrible, but the head gasket had the fire ring. The materials on the other parts were good. Seal had the same identification as the seal I got at the kohler dealer.

Cleaniness and good machine work and it should last for decades with regular oil changes.

How can I I d this motor ? It has a 3 1/2" bore. I didn't check the stroke before I tore it down, at that time I had no idea there was no id tag on it.

You have a K321 14hp motor.

Can anybody tell me what the valve to guide clearances should be ? I noticed the exh valves stem is .002 bigger than the intakes in this motor. clearance is now .002 on the exhaust and .004 on the intake.
