Howdy All,
I traded 2 rusty 55 gallon drums for an old trailer door to my neighbor the other day. While taking one of the drums past an old junk shed I saw the nastiest, dirtiest looking chainsaw sitting on the junk heap.
I asked him what was up with the chainsaw and he said "it wont run, no spark". So I told him I would look at it, if he did not mind. Up the hollow I went.
He later told me it had been sitting in there for two years. No top cover and no spark plug. Open cylinder. This saw looked like someone set down in a mudhole running. I put an old plug in her and took off the side covers, bar and chain. They where pretty rusty but did clean up.
Well I put the water hose to her with simple green, WD-40, PB blaster, and compressed air. Took a couple hours but it was looking better,
Cleared the bench and drop checked her, slow jerky decent. Ther may be some hope. Compression tester said 145. Looking good so far. The kill switch wire was disconnected and the spark plug wire had a splice. Took out the coil, wd-40 wire brush and steel wool. Clean off fly wheel and steel wooled that to. Coil read 6.5K ohms and switch ohmed out good at first, then was intermittent. Drilled out rivets too switch apart and it was full of grease. I saw tiny brass looking flakes in the grease. Can grease become conductive with these flakes? I cleaned it out and rechecked, dead short on stop posistion and infinity on run posistion. Crazy glued switch cover back on and seales her up with some permatex sealant that can withstand gasoline.
Redid splice in spark plug wire and put back together enough to pull the starter rope and got nice blue spark.
Pulled muffler cylinder, rings and piston looked pretty good. I did flush some mix through her. Cleaned carb found, cracked feul line, lines in tank were beyond repair. Replaced fuel lines blew out feul filter and fixed crimped tank vent.
Put some mix in her, chocked her and she started on about the sixth pull.
It does need a carb adjustment and top cover but she sounds real good. He said it will be his back up saw. If it was mine I think it might be my main saw.
I really enjoyed tinkering on it and I like some of the designs in it's engineering, like the dual feul pick ups, no impulse line, air cleaner, simple stater assembly, two points attaching the chain brake handle and inboard clutch with rim sprokcket but there are some down sides to it. Cheaply made oil and gas caps, no much room to thread a nut on the kill switch, plastic chain gaurd on inside of side cover, rubber mounts could be better, vibrates some and not so sturdly made trigger saftey components.
Folks not sure I could of fixed it without knowledg gain from this site. I salute you. I'm happy I did a good deed for a good neighbor and hes happy he has a back up saw.
Now I'm looking for another one to work on.
Thanks
