I have 2 powerheads up for sale or trade. Both have scoring on the piston. I got these as part of a trade so I don't know much about them other than what I can see. They both look complete with the exception of the PP missing 1 muffler bolt and a hand guard screw. $50 each plus shipping or trade. Things I need would be a cylinder and piston for one of them and you get the other; a top cover, air filter, filter cover, and rubber bushing for a Poulan 3400; Husqvarna 346 top end; Husqvarna 61 top cover, air filter, and piston; Poulan 245a parts. Just hit me up with an offer if interested. I just have too many projects and not enough funds for them.
