After finally getting my carb adjusted and the saw working decently again. I think I may have found my original cause of stalling and plug fouling. When I started cutting again, after the saw got good and warmed up it started to bog down. I pulled it out of the piece to rev it, but it seemed like the chain brake was engaged. The lever was in the disengaged position but the chain wouldn't turn. After the saw stalled out, the chain was free again. Is anybody familiar with how the chainbrake works? Is it a job that can be repaired by someone who is reasonably mechanically inclined? There was a link in one of the threads to a web page that showed parts lists and blow-up diagrams for poulan saws but I can't find it. If anyone has this link, could you post it again? I know it's not a top of the line saw, but it has performed pretty much flawlessly up until now. I'd like to take one more stab at fixing it.
