1994 Dyna, Mikuni 42 carb. When running the bike at idle or very low throttle position, the fuel is coming through the main jet in massive amounts. The bike will not idle without cracking the throttle, and with the bike running looking through the carb, fuel is gushing through the needle jet. Carb is clean, new float valve & seat, float adjusted properly. It does not overflow with the motor off. Some reason it is pulling fuel through the main jet when it shouldn't be.
