Just got these saws today for free. They obviously need a lot of work and some parts. The ladies relative said the engines were shot but from my brief assessment I don’t believe anyone went deep enough into these saws to confirm the motor is gone. Looking at the 440, I can turn the flywheel by hand and the decompression valve is stuck down by the cover and letting the air pass by (I wonder if that’s the main issue). The Ms 460 is pretty far gone. Can’t turn the flywheel by hand. Could just be the clutch damage on the other side. Figured I would post this here in lieu of y’all advice on where I should start with these. What are good aftermarket parts, advice on some of these repairs/tests. If I had to get a new cylinder head for the 460. What is a good brand to go with as well as carburetors. If you have any of these parts you don’t need/willing to part with please let me know. I have many years of automotive diagnostic experience but I’m very green in the two stroke/chainsaw world. Took apart a couple to fix them but never to this degree. Thanks for the help as always!
