Looking for Parts Information for a Stihl 042AV

[Chainsaw Pete]

I've got an 042AV that was given to me about 25 years ago. I used it to clear our overgrown back yard when we bought this house and took down 13 or 14 trees. I had some trouble with the saw and took it to a couple of shops. One place did something and got it running strongly again, and when it started running rough again, I bit the bullet and took it to my local Stihl stealer. They took it apart, told me it was obsolete and parts were not available, and said it would cost an additional $$$$ (I don't remember the amount now) to put it back together. I took it home in a box, did some research and an old time saw guy online told me to swap out the carb with a new WS25. He said blowing out the Stihl carb with compressed air can damage a check valve and that the dealer or some service guy may have done that. After a multi year search on ebay a NOS carb came up. I put the carb on the saw, got it all together, and it has been sitting on a shelf in my basement for years. I've decided to get this running again.

Can anyone direct me to an exploded diagram of the saw with Stihl part numbers? I have the 042 Service Manual. Any suggestions on sources for old parts?

I've found that sawzillaparts.com has some proline parts - ignition coil, the plastic switch parts,etc. I'm still looking for sources, even though I don't need much more than the coil and switch parts.

Any suggestions for good chainsaw mechanics who can get this running should I fail to do so myself? I'm in Northeast Ohio, but I'd seriously consider shipping it to someone.

Sawzilla has your exploded 042 parts list, but 042 specific parts may be tough to find.

There are quite a few new Proline parts available for these saws now. It used to be incredibly hard to find parts such as pistons, control lever, crank seals, clutch cover, etc. You can buy them all now from Proline. I'm running a Proline piston on my 048 and it seems to be doing great.

I've found Proline parts from Sawzilla. Are they the exclusive distributors or does Proline Small Engine Products have a website?

Look at the bottom of the crankcase to make sure the gasket is not blown out. #1 reason 42/48 have running issues.
Used to have 1 a month back in the 80s.

With the admonishment of the repair guy that the carbs are bad, (and he's not steered me wrong in the past), along with the advice of a few here, I bought 2 new carbs from Amazon. Not sure when they'll go in, but I'll try to keep you posted.

If you find a good piston and cylinder please let me know I was given an 042 by my dad that I saw sit on a shelf in his garage my entire childhood and I got it cleaned the carb and fixed the kill switch wire and it was my favorite saw ran sooo good heavy but powerful and I was milling some cedar and wasn’t paying attention and the tailings plugged up the start cover and well that’s where it sucks in cool air for the motor and well it seized up I got it free had to unstick the rings and then it ran again for a while but not like it used to and now she won’t start low compression I wanna fix it but I have had hell finding parts I’ve been looking for about four years
