This carb still chucking fuel out overflow. New float valve installed and no change. Fiddled with tang to adjust floats..got overfilling stopped, but then bike was getting no fuel and would not start. Moved tang back a touch then bike starts but fuel coming out overflow again. Took carb to a friend of mine who suggested the float valve from Yambits is faulty. The pin on the needle sems to have too much tension on it so floats won`t be able to close it. Can this be?..when if i bend the tang way down the fuel is stopped completely. I even tried putting the old float valve back in but still overfills. Any suggestions? Should I fiddle the tang more with new float valve installed? If its set to spec though (21mm), it persists in overfilling.
