I've found a bar and piston for $50. The saw was free, but I'm aiming on keeping the saw and selling my 55 rancher. And my Poulan 3400 so any proceeds will go to the saw and any profits will be to boot. The saw is really good condition only one small chip on the clutch cover. As for the time, I'm 17, no girl friend, no car, no real responsibilities, so time is free for me. Working on saws is fun for me, so if I can't make money well I'll keep it.
Hang on there, slugger. I like an 029 as much as anyone, and better than most here. With that said, I don't think I'd sell a Husky 55 (even an open port one) to fund any 029 rebuilds. Even though I despise the oiler on the 55, it is a solid machine and quite equal to or better than the 029 in almost every regard other than said oiler (which works fine, but just aggravates me since it is always pumping.) Yes, I have several of both, and a ton of trigger time on each.
Also, selling of 3400's is just plain bad manners (plus you'll only get $50-$75 for it.) One day soon you'll stick your 029 in a cut, and wish you had your 3400 back too free it.
You are right to rescue the 029. You should have seen the one I put together that WorkSawCollector trash-picked several years ago. There was a thread on it back a ways - something about a pile of wildthingies in the title. Anyway, just get the parts one at a time. Do some reading before you plunk down any coin for a new piston from the aftermarket. Some of that stuff is very good, and some is not. Post up on your progress, and help will find you.
