HELP! identify this Stihl chainsaw

[pyle-opef]

I’m kinda new to this forum saying hi to everyone.

Just get this dirty chainsaw few weeks ago (looked like all original ) with no model identifier anywhere on it. The sticker on the cover is missing so after hours of cleaning, I’ve took some pictures & trying to ask experts on this forum helping to identify what model of the chainsaw is it ?

• Cylinder Stihl1121 22 w letter B in the middle
• Carburator stamped number 22C & Stihl marking on its bottom cover.
• brown air filter with black lever
• Serial number 220618806
• leaks lot of oil below the chain bar

some more advices ?
Many thanks in advance

It's also possible to write a Email to Stihl. Include the seriel number and you get the right answer.

That appears to be an 034 . 026. Make sure you replace that air filter. The flocking is gone, and fines will get in.

That’s an 026

Yeah, you're totally right. It looked bigger to me for some reason. Plus, 1121 is 024/026.

It's now know as a Stihl026 - Many thanks for all helps.

Oil leaking a lot at idle - Have been told that an adjustment oil pump conversion could bring a certain benefit.
Is it worth doing or better off just leaving it alone ?

The oil pump is not clutch driven, so it will constantly pump oil even when the chain is not moving. The 026 Pro came witb a clutch driven pump with adjustable output. Some 026's with the accommodating notch in the case can be converted to the Pro style pump, but you also need the matching clutch drum and oiler drive. Most people agree that it isn't worth the effort.
