My weedeater was working fine, then just quit. Turns out my fuel lines had broken in the tank, so I replaced them. Now it will start briefly on full choke, but when I switch to part choke it just WANTS to start. Am I missing something? I don't have a manual so I don't know how to make any adjustments.

Did you old fuel line have what's called a clunker fuel filter, did you replace it?
