Okay first off, I'm not new to these 2 stroke engines. Why everyone assumes that someone who words things so everyone can understand them are called newbies, I have no idea. I know that the so called 80cc engines actually have a discplacement of 66cc, I just figured that that's what people would recognize it as. The two engines are 66cc skyhawk silver slant head engines, nowhere did I say they were grubee or flying horse, or a happytime. The two sprockets are both 44 toothed...
And Augidog, calm down, you sound like I was attacking you or something! To my knowledge, these engines are the same model, I've checked the carbs and jets, the exhausts are diffrent but we interchanged them before and had no significant diffrence. No, I have not torn these engines down as far as the crankcase, and that might be were the answers lie, but I am not new to all of this...
Anyway, thanks for all the responses, I just couldn't figure out what gave my friend the edge, but soon or later I'll have an answer. I thought the power diffrences could have been from better port polishing (if there is any) or just upgraded parts.
