May have better luck posting a “Want to Buy” cylinder request in the Tradin’ Post section, also a likely place for the Poulan haters to dump a 306 parts saw.
Good 306 jugs are getting hard to find, as the chrome plating under exhaust port chips off when overheated.
The model 245 top end off a parts saw is a direct swap too, but you’ll need the piston & con rod. Same parts used on the orange Dayton 2Z462 & 463 saws, if you find one.
The Poulan 361 cylinder won’t work.
