are you speaking of the idle on the carb? because you stated you did not want to mess with,,,, if it is running like you want it to I would not mess with it, I did increase my idle about 250 rpm to about 800, seems to like it better their,,go google for this site ,Recarbco, I have trouble with the copy and paste,,,it is a good site with a lot of good carb tips. I got mine re-done by them about 2yrs ago,,see ya........Fred
