Beanie, it sounds like you might have a problem with the oil pressure controlled shut-off.. See if unscrewing the knurled nut on the side of fuel shut-off then holding it down helps the fuel flow to the carb.. OR, use some tubing & fittings to by-pass the auto fuel shut-off & see if it then gets a good continuous flow to the carb.. You might have to pull that "auto-fuel-shut-off" back out & do a bench test to find the problem.. Low oil pressure can also cause it to not open correctly.. Other thoughts: If the carb is allowing all the fuel to drain off after pony shut-down it will have to be cranked over for an extended time to allow oil pressure to build before fuel will start flowing.. If you shut the manual shut-off down & allow the carb to run dry you will have the same effect as low oil pressure & have excess cranking time to get initial fuel flow. If the fuel tank is allowed to run low the fuel height in the tank won�t be high enough to force fuel up & past the oil pressure shut-off.. Make sure that tank is always full before starting.. Try cupping your hand over the fuel door tank filler & blowing into the tank to pressurize it slightly before starting [if that helps you will have to figure out where the [slight] restriction is occurring]. With that fuel tank being at about carb height the fuel flow to that carb is marginal even when the system is functioning correctly.. Let us know what you find? [email protected]
