I have a 1990 Honda Elite SB50P . I am seeming to be having a problem getting Fuel into the Motor. If i poor some down the Plug Hole, and start it it will runn until it runs out of gas in the cylinder. But that is the only way to get it to start. I have bought and installed a new fuel filter. So i know fuel is going to the carb. Anyone know what might be causing this? I am new to scooters. BTW this bike sat for a while so i have not taken the carb apart.
