I was wondering if anyone could help me out. I have moded my 1979 Puch maxi and was hoping to get some more power out of it. Actually, so far most things have gone pretty good but I think that I am still lacking all the power that I should have. So far I have upgraded the piston/cylinder(is now 70cc) and I put a more powerful bit turbo exhaust. I still only hit a top speed of about 35mph. Which was better then what I was doing but still lower then I expect. I am assuming that the bottle neck right now is my old bing carb. I think it is like a 14 or 15mm intake, and I am not sure if it is even fully operational. I was wondering if any one could help me out as to what kind of carb I can buy to go along with the rest of my upgrades. I have been looking on ebay and stuff and I just have no real clue what brand I can get, how big I can go, and just what will fit? Any and all help or suggestions with either the carb or any other ideas about improving performance will be graciously accepted.
Thanks for reading.
