So I picked up my ms390 2 seasons ago. Was cutting a tree for a friend. Got all done with one tree when their son came over and had one he wanted cut up so he could move it. I get there, and the saw won't start. I sent it into the shop and was told I was 125 psi short on compression. He said I could put a set of rings in it and use it for a while, but the right way to fix it would be to put a new top end. He said the cylinder wasn't scored. He said I was running very very lean, which I didn't like, since he was the only what that's worked on it.
Anyways, I kept my saw, and have since upgraded to a ms660. I'd like to put a big bore kit on my 390, but from what I have read, no one makes one. I'd like to try to rebuild it myself, to save some dough in having someone else do it, and it gives me something to do. I also wouldn't mind having a backup saw. For the amount I was quoted to have the shop fix it, I could spend a little more and have a brand new saw.
What would you do with something like this? Worth the time and money to get it going again or just scrap it out? Your thoughts.
