Stihl Chainsaw Specifications

Any link on the web where I can find chainsaw specifications such as fuel mixture ratios? I have some older saws Stihl 015L, 031av, 041 farmboss) that I suspect may call for various mixture ratios. I have no manuals on them. What happens if you add a 50:1 mixture in an engine that calls for a 30:1 mixture. Could it cause problems when trying to adjust a rebuilt carb on my 031av? Adjusting this 031av rebuild carb continues to be a real challenge! :bang:

You can order owner's manuals from Stihl for free. For service manuals, check out Tom Thompson's site-

As for oil ratios, do a search. It's been hashed to death. Some say that older oils didn't lubricate as well as newer ones, and thus the need for a lower ratio. It goes on and on.

Use a major brand oil, like Stihl or Echo or..., and just run them on 50:1. If you're worried, 40:1, but it makes no difference. Yes, this has been hashed over a zillion times but the bottom line is that the modern oils are better.

Also if you haven't yet seen Mike Acres site, go to this link, go to the chainsaw section, and browse forward to the Stihl section.
