I know it’s not a chainsaw but it’s close. I’m having issues with the primer bulb being sucked in from suction build up. All fuel lines are open. I switched in a new carb with same results. The bulb even works fine. When it’s together enough to run u can’t see around the carb for pinched fuel lines but don’t think it’s that. Anyone have some insight on this?

No double wall, technically it sucks gas through the carb first, then into the bulb, then the bulb ejects the gas back into the tank correct? The tube from bulb to tank is just a dump, it doesn’t (and doesn’t reach gas) going into the tank, just the pickup going into the carb does correct?

Safe to assume the carb is restricting flow, and the new one for that matter?
