This is for my friends shee so bear with me here. It will randomly overflow out of the left carb because the float is sticking I believe. I think this because when you tap on the bowl it'll stop. It also runs on only 1 cylinder some of the time unless WOT. Does the carb just need cleaned out?
Also, clutch slips only at high rpms in 3,4,5th gears. New clutch in order?
Thanks!
