OK. There's a story. Bought this new at Crater Chainsaw in Medford. Used it about once a month in the summers. Always ran great, BUT...
It started stalling unless the choke was on. Did a bit of research and cleaned the carb. No improvement. Bought a NEW Sthil carb. No improvement.
Still starts and runs, but only with the choke on. You likely know more than I do, so maybe with a tweak, you can make this work better than I can. Comes with the new carb mounted as well as the old carb.
Head is good and has no other issues. It's worth more in parts than the asking price if you decide to part it out.
