I have a troy-bilt 2-cycle gasoline trimmer (model TB75SS) and when depressing the primer bulb, no fuel will feed. Plus also do not see fuel moving in the fuel line when priming? Any ideas?

Hi check that the primer bulb has not perished thru age sometimes they split and suck in air instead of fuel you can remove these by taking out two little screws and check it out if it has perished or split renew it. If not check for blockage in pipe line in the one going to the fuel tank there should be a filter on the end of it in the tank make sure it is not blocked hope this helps Regards Jim
