This question is related to my other post about carb adjust as I'm trying to track down misfire and sputtering issues. Plugs are definetly carboned fouled and I'm going to adjust the carbs from scratch but was wondering about plug gap?...Manual says.032 for TR3A(1991cc?) and .025 for TR4A(2138cc)......is the difference because of engine size? In any event, is anyone running a 3 with a mild street cam and header and what do they set their gap at?
