I have most what you don't for the 028's.
Also have a poulan pro 260 I got out of a scrap pile, not the greatest overall condition but some usable parts.
Have a craftsman - red poulan top handle in lesser condition then the 260.
Also have an older blue xl12 homelite, with a broken handle mount on top and the bar is lightly bent I believe, it fires on prime,think it needs a fuel line, may be the carb gone through would get it going, or who knows. Compression feels good. I think its pretty much complete except the broken - bent prts and looks good for its age.
Have some bars,mostly new, most 20"and less, Husky mounts, Stihl, 16" fit old echo + Mac, some new and used small bars I'm not sure what all they fit but probably could figure it out if needed.
If no one else is ahead of me, i'd be interested in the 041 provided the ignition system is good.
Interested in new chainsaw chains 3/8 and .325 most any length if someone wants to trade theirs they don't need.
While I'm at it, I'm fixin for a friend, if I can find the parts way less then what new cost from stihl,a ts 400 stihl. Needs a flywheel,and coil, and I think the air filter cover and and the filter elements unless he has them at home.
