I need some help. I'm trying to break in my GO .25 6 Port. I can't get the gas to the carb without taking the pressure tube off the header and blowing the fuel into the carb. When I'm trying to start it and squeeze the throttle the gas actually pushes out of the carb. I've sealed the backplate and the bottom of the carb with sealant. I got the black two needle carb. When I do get it started and can rev it, as soon as I remove the glow plug igniter it cuts off. I heat the head with a blow dryer and wrap the head with foil to get the temps up.

HALP!!
