Ok please no one shoot me but I was wondering if we could get a discussion started reguarding carb sizes on engine conversions. I like to hear from people who have tried different size carbs on different size engines and does increasing the throat size make that much difference. I have a few carbs with even amounts of small and larger throats and not sure which I will use. The engines Im wondering about range from 30cc to 45-50cc but not any one brand specificly. Just curious as to what others have come up with ??????
