The thing only starts when you pour gas only the airfilter. After it gets warm it will start right up. Mods which might have an effect are as follows, coolhead 22cc domes, fmf fattys, FMF reeds. Main jet is a 310, carbs were just rebuit. I thought maybe there was not enough compression to suck the fuel in? But why would dumping gas on the airfilter helps it? Bad reeds? Any advice would be appreciated.
PS: Im also looking to buy some 28mm carbs if anyone has some laying around
