More diagnosis.
Flywheel is pulled and it did not spin. The integral key is intact and in the crankshaft keyway.
Piston is scored, but......
I contacted the original owner. Here is some history on the saw. He purchased it new. Supposedly he accidentally poured drain oil in the fuel tank one time, without knowing it. (He had drain oil in a fuel can, not sure why) He started the saw back up and it ran a little bit and locked up. He took it to the dealer and they repaired it. (no clue as to what they actually did) He got the saw back and ran about 1 tank through it and it locked up again. He went and bought a new saw.
He gave me the saw as a project. I have a few other saws and 60 acres of woods. He said it locked up as the recoil was pulled out and wrapped around the handle. I found the spring loaded tabs on the flywheel to be locked up and I free'd them and the recoil started working properly. It would still not start and I started to dive into it.
Aside from the scored piston, I was able to check compression with a gauge. Good or bad news, I only have 80psi after five complete pulls of the starter rope. I believe I should have 110-120 minimum. So that goes along with the scored piston.
I have been told that the 390 piston and cylinder is a bolt on replacement for the 385XP if I wish. As long as I may have to replace the jug and can, should I just go that route?
Do we have any reputable Husky dealers on this site that I can either buy from or get a price check from? I have a good relationship with my Stihl dealer but am really wondering if my Husky dealer is raking me over the coals. I haven't checked prices for this yet but I have another part I could use as a "for instance".
So yes, fuel and spark won't do squat without good compression. I had compression, just not enough.
Let me know what you all think.
