358351480 Craftsman Chainsaw - Instructions

He didn't want to spend alot of money on it. So I got the jug (Head) off and sanded it and the piston down while I waited on the new piston ring to get here. I found that it was easier putting the new ring in and the piston back into the jug (Head) was to go ahead and take the piston out so you could turn the jug (Head) upside down and it slid right in. It didn't take no time at all. And it now runs as good as new

Straight forward, trick for the piston ring was to cut a soda can to make a sleeve that could be wrapped around the piston ring. A bit of duct tape with a tab held it shut until the piston was in position then it was easily removed as the piston was slid in.

Took chainsaw apart and replaced the ring.

Seven screw, three case cover, two air cleaner, two carb mounting, pulled carb, drained tank, pulled old fuel line, treaded new one in, wire to thread, thread to angle cut fuel line. Reassemble, test, sharpen chain, retest…not exactly a doityourselfer, graduate degree in mechanical/industrial engineering and former medium/heavy mechanical. Get fuel line on carb prior to reassembly, line may need some stretching with a tapered punch.
