Hello, I just purchased on of those cheap "racing style" carbs that came with several jets ranging from 65-80. I installed the carb, and it seemed to run slower than the stock carb. I took the jet out, and it did not have any markings as to what size it is. I have a 66cc engine with a 6cc, CNC head. Anyone running a similar setup, and what jet size do you use.
