We run a 38 pilot and 130 main here (about sea level to maybe 300' ASL).

I am not sure what carburetor that one runs, but it's 25 year old cousins liked a pilot up to 50 to start good in the really cold months and in the summer drop down to the same 35 david uses. with a freer flowing exhaust we would start a little higher at the top (140) but we are right at sea level and usually cooler than where he is too. good old motor.
