Hi Guys, 1980 that quit wanting to start. The clear fuel filter showed barely any fuel dribbling in. Replaced the fuel pump with the current Bayliss mechanical and now nothing. When you suck on the outtake line to the carb you can hear air entering the check valve. No change in starting when I tried to block off the check valve hole. Any other ideas on why no fuel? Bad sending unit in the tank or similar? Fuel does appear when sucking on intake line from the tank. Please advise. thanks!
