I use the NAPA shop in Richmond, VA. Talk to Karl, 804-321-7467.

Bob, the governor gear is driven by but not timed to the camshaft.

Are you using the Kohler Service Manual?

Do yourself a favor and find a good machine shop and have them do the work. Most definitely get the crank measured if you can’t do it yourself. The last one I took apart was .008 out of round on the rod journal. Yes these little engines are expensive to rebuild but in the end it will be worth it. Any automotive/performance shop should do the work or be able to direct you to a shop that will. If you’re really desperate I can give you an address to the shop I use. Last one got crank turned,bored,guides,and seats ground to match the new valves for around $250

No they aren't. They are really cheap!! Go price parts for a Mag or a KT engine! These Kohlers can be rebuilt for around $350 in parts and machine work unless you need odd parts, or ones not often replaced.

Not all automotive rebuild shops will touch a small engine. $250 is pretty high for what you had done. Between $50 and $100 high.... I'd shop around some more.

I think I pay about $175 for cylinder bore, crank polish, and valve seats re-cut. Add $100 for the rebuild kit, a few more dollars for replacement bolts, sealant, etc. Like Jon said, under $350.

Thanks sawdustdad for the Napa number. Will give him a call.
Twoton, I am using the Kohler service manual but some times I over look things or just simply don't understand them. I wasn't sure about the governor so I left it in the block. If I can get the block, piston, and cranked checked I will remove the governor. I really appreciate every one's help. Have a great day.

Governor is easy to take out. Just remove it. Need to check it out anyway.

Oh good. I was just wondering. I bought the one from Maple Hunter as I like to have a hard copy. Gives me something to look at during my coffee break.

I was wondering if you recall any oil leaks at the governor cross shaft/bushing and if you have removed those? Just curious,..I think some would replace those as a normal course of action...

Strange things happen. A few weeks ago I called Givens machine shop in Charleston, Wv. Talked to a lady that answered the phone. Asked her if they could bore an old Kohler engine. She hollered to some one to see if they could. She said no. Thought I would try again today. Called and a man answered. Asked him the same question and he said they sure could. Bore it 10, 20 or 30 over. Said they would check the cyl, piston and crank to see what needed to be done. Going to try and take it to them tomorrow. I sure hope they can do the work.

Twoton, the service manual I have was downloaded from the tech. section and printed out. I am going to remove the governor today. Did not see any leakage from the shaft. Thanks and have another great day.

Took the engine block, crank shaft, piston and valves to machine shop yesterday. Hopefully they will get back to me Mon. or Tue. as to what needs to be done and the cost. Thanks for every one's help. I am sure I will need help as I put this engine back together. If any one knows of any thing that I should be aware of, please let me know. Have a great day.
