First off welcome to the group! Here is something to try. When setting the high speed needle, have the engine running at full throttle. Then slowly back out the needle valve untill you get black smoke and the engine starts to slow down a bit. At this point the engine is running too rich. Now very slowly start to turn the needle valve back in. Turn it just far enoiugh to get rid of the black smoke and to the point that the engine smooths out and runs well. It sounds like your engine is running to lean at wide open throttle. You couild have other problems, the engine surging may be a govenor adjustment issue but try adjusting the high speed needle first. Good luck, Mike
Thank you for the response Mike,
Should I have the PTO engaged while setting the high speed needle? I read that I should and that is how I set it - really have to watch your feet. Anyway, I will adjust the HS needle without the PTO engaged and see if I can unlock the answer. I do lose some oil from the governor shaft, but not nearly as much since adding a brass bushing which covers a less worn portion of the shaft. My concern with the slight leak is, if oil is leaking out, might air be sucked in? However, I can't be the only one with a kohler engine leaking oil.
Thank you again!
