I have put an electric fuel pump in line back near the tank with a spring return switch. You hold the switch on for a few seconds & it is all primed.
It also helps if you pump the gas pedal as you crank the engine. The accel. pump pulls off or near the bottom of the float bowl. When a little fuel gets in the bowl the pump will prime the carb. Other wise you have to fill the bowl all the way for the air pull the fuel from the outlet.
