So.... I'm back again, and my saw finally died.

I have no idea, no time, no ability, and no desire to rebuild it.   Because I don't know how to trouble shoot it anyhow, so I'll just as likely fry the new parts.   

I looked at it for about 5 minutes, thought "Huh, I have no clue how to get this thing apart, let alone back together if I did."

If they built chainsaws out of dovetailed hardwood, I bet I could fix it. 

If you have the tools you can do it, i think they have the hole break down on youtube.
Take pictures as you go, once you get started you wouldn't believe how simple it is to put a head an piston on that saw.
One of the main things is to take the bar an chain off, then the rewind, then blow it out real good before disassembly.

The ability of being able to work on anything is an acquired skill .Nobody was born with the ablity ,you just have to learn it .

Chainsaws aren't that difficult in spite of what some might say but you'll never learn unless you do it .However if you don't have the desire you'll never learn .

I used my 290 today. Worked beautiful. Stihl going strong all day long. Ok, I didn't use it all day long, but it worked great, I stihl love it. Almost 7 years later, it's my forever saw.
