Homelite string trimmer fuel issue - primer bulb? Zephyr 07-15-2008

Hey there,

I am working on reserecting a homelite string trimmer that was
discarded. Compression seems good, there is spark, and I have fresh
fuel, but, none seems to be getting into the carb. Pumping the
primer bulb results in the fuel tank being pressurized and a squeek
noise, but no fuel getting into the bulb itself. You can hear a hiss
as you remove the gas cap after priming and the lines blow bubbles in
the 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 thru
the lines towards the tank, - so I think the fuel filter is clear
still) This makes me think the issue is in the carb itself. Does
that make sense to you guys ( and gals) ? Any quick fixes to try? I
am planning on tearing appart the carb next and cleaning it out as
best I can.


this is my model

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

Sometimes blowing half a can of choke/carb cleaner at it will help too. Soak
it good!

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

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