Chainsaw Repair

Based entirely on the pix and P&C part# of your sears model and that it is NON AV like mine I would say a 2150"LE" 42cc. I have several 2150 and they are usually 36cc except the LE @42cc. I put the same 42cc jug and piston on my rebuild since they are the cheaper than the smaller one. All the rest of the parts are mostly the same. The 1975 is very similar and I have not researched enough to tell the difference from the 2150.
