Homelite string trimmer fuel issue - primer bulb?

Question

Hey there,I am working on reserecting a homelite string trimmer that wasdiscarded.  Compression seems good, there is spark, and I have freshfuel,  but,  none seems to be getting into the carb.    Pumping  theprimer bulb results in the fuel tank being pressurized and a squeeknoise, but no fuel getting into the bulb itself.  You can hear a hissas you remove the gas cap after priming and the lines blow bubbles inthe gas as you prime.  I disconnected the fuel lines from the carb,and they are clean leading into the tank.  ( IE I can blow air thruthe lines towards the tank, - so I think the fuel filter is clearstill)  This makes me think the issue is in the carb itself.   Doesthat make sense to you guys ( and gals) ?   Any quick fixes to try?  Iam planning on tearing appart the carb next and cleaning it out asbest I can.this is my modelthanksDave

Sounds like a clogged jet in your carb.  Try opening your choke plateand cleaning it out with a small wire.BRW

Perhaps the fuel lines are crossed ... Swap them and retry?

more likely, it is a lugged needle valve in the carb.

There is tiny plastic tubing connecting gas in the tank and the bulb? Look for breakage etc in the tubing, particularly where it connects under the bulb.

Could be a tiny air leak at the base of the bulb, too. Squirt some wd-40 or even soap water around base of the bulb, look for bubbles.

I'm guessing its sucking air instead of gas.
