I replaced all fuel lines, old one swere cracked. Now trimmer will only run when choke is fully engaged. It dies when placed in anyother position. I can't find any manuals or anything for this trimmer. It is a 28cc powerhead, McCulloch MT3336

0 All I can seem to find are parts diagrams... However, I have encountered the same tormenting issue for quite some time... The only solution I can seem to correct the problem is the bottom adjustment screw (maybe an old worn out spring, perhaps?)... However, there are starting instructions on the handle-shaft on a sticker... When I get a chance I will upload the sticker! Usually I've never had to follow them, for I could never ever keep it running on position 3... :-( ... I do know that the top of the gas tank where the fuel lines come out is cracked like no tomorrow (which may get permatexted sooner than later), but the real issue from my experience is still related to that lower adjustment screw/spring (the plastic white one, for reference). Good luck! If you figure out anymore let me know as well, for it is indeed a good weed whip trimmer!
