My 1980 Puch Maxi Luxe moped runs fine on flat land but now it looses power going up hills. I recently put on a new piston kit, which included a performance head and new piston ( new gaskets also ). It was a kit I bought from MopedJunkYard, which said it was a replacement for my existing High Torgue head etc. My moped starts and idles fine and seems to run smoothly untill I start going up hills ( then it basically boggs down and just quits climbing ). Because it was a new piston and head, should I try a larger jet to see if that helps. There don't seem to be any air leaks but I will start it up again later on today and try spraying carb cleaner near and around the manifold, head, carb etc to see if the engine starts to stall out. Would it be possible to install a new 15mm Bing carb and 15 mm manifold to replace my 12mm cab setup? I started a tread earlier and ask about modifing my E50 engine to go from 1-1/2 Hp to 2 HP, would this be something fairly easy to do. Maybe just put on and new 14mm manifold to try and get more air? I covered the carb when it was idling good with my finger ( on the airfilter side ) and the engine stopped.
Before I made any mods the bike would climb hills fairly well, but now on the same hills it just won't go up with bogging down to a stop.
I would really like more HP anyway to climb the hills better.
