Ok so here's my situation. I have a 1979 Moby 50v that due to stripped exhaust and spark plug threads, I decided to refit with a 74cc airsal kit, a dellorto 15.15, and new stock exhaust. Well the other night I finally got it up and running, and with a few minor adjustments she was running better and faster than ever. So I took it out for a maiden voyage, and it ran great for a good while but upon subsequent start ups I first noticed idling problems, then trouble starting up at all. What I'm experiencing now is extreme difficulty in starting(it'll get going barely, and will only finally take off with a ton of pedaling). Once it's up and running it'll run just fine at high speed but at low speed almost no power and real trouble idling unless it's real warmed up. Throttle and decompression are adjusted fine, As is the idle pin. I'm just wondering if that one ride with the new added power would be enough to mess up the variator or ignition timing, which seemed fine before? Sorry for the long post just trying to be thorough.
