o.k. new here so intro first, im jason, experianced rider with passion for 2 stroke. now down to the problem at hand... After many attempts and differing problems my tzr 125 88 made her first cough last week, build from bits with alot of help from ebay and haynes. BUT... she wont start, problem being no (very little) fuel is getting to the engine (spark plug's dry), so 1st thought CARB, checked float hight n condition, jets, pipes, tap, intake, everything, no visable or apparent problems, its a standard 28mm mikuni, custom air filter (k n N), ov bore 1.0 + piston oversize, single ring (top) she intermitently backfires and pisses fuel out from all 3 over flow pipes but ive got no further than that, all earths checked n is a new cdi. Any advice or just a comiserating warm welcome, i'd be happy with both. regards jason
