How old is your Kohler? You might want to try some Marvel Mystery Oil in the oil and/or gas. Suppose to clean up the valves/lifters when used in the oil..... lots of people seem to swear by it on some other lawn/garden tractor groups.

Small gas engines usually use straight 30wt or that multi weight you are using. But try a little Marvel in the crank case.
