I have a Homelite weed trimmer model ST-155. Started having problems with it staying running and discovered the primer bulb was cracked. I replaced it and the new one won't pump any fuel up from the tank. I replaced the fuel lines and filter last year and they seem to be fine. I can blow into the fuel line and it will come running back out fine. I keep pumping it but no fuel comes up into the bulb. I took the carb apart and cleaned all ports out with cleaner and made sure every part went back together the correct way, but still no fuel. Any advise would be welcomed.
