Yeah, thats pretty much it. I've put a couple 60 and 70cc kits on other puchs, then I got rid of all of them and bought a 64cc Polini kit for my baby...the first one I ever got. Anyways...I have a larger carb from another 70cc kit that I had, but I can't mount it with the reed valve/intake that they provided, what should I do? I haven't tinkered with the moped in three or four years, but it runs real rough until 15-20 mph's with the stock carb.
To those of you who bought the 64cc Polini kit - WHAT SHOULD I DO FOR NASTY PERFORMANCE?
