Default Stihl 041 AV Super

So, I started in on giving my old saw some TLC. I bought it through a NPS surplus auction years ago. I suspect it may have been a Hotshot crew saw. But, that is just a guess. It's been used hard but well maintained. It came without a bar and chain. I bought a bar and a couple chains and it's been running ever since. It set for awhile as I have been using the newer smaller saw. So, the carb got torn down and thrown in the new Ultrasonic Cleaner (Greatest Thing Since Sliced Bread ) The diaphrams in the carb are too stiff and FUBAR so I have to hunt down a kit for it.. But, I discovered a mystery to me once I had the carb pulled off. Never knew it existed. I'm assuming it's some kind of reduction gearbox?? Before I crack the lid am I right and what does Stihl run in it?

Sign up on arboristsite.com and go to the beg for manuals forum. Ask for the parts list and the service manual.

Find a Stihl dealer in your area. Usually a lawnmower/power equipment sales/repair place. They can probably help you and you support the little guy.

I got real curious cause I've never seen that on a saw before...and I looked all over and couldn't find an answer for you

There is a fairly good "rebuild" video on youtube but he really just works on the fuel system for the most part and never mentions the cap even though he's working all around it.

On the parts diagram I found for it, the cap is there with several parts underneath it but none of them were labeled. It appears to have to do with the oiler. I found an ad for an oiler control knob for your saw, and it looks like that may be the part.

Stihl does sell a gear lube and there are 2 different products, one being listed for hedge clippers/shears and the other saying it is for chainsaws, but I don't know anything about either one. Just saw a link to a sales ad for them on ebay with some discussion. I've never heard of a chainsaw needing the crank case lubed, so I'm leaning more towards that having to do with the oiler system.

Thanks Matt, you know when you process problems in your sleep. I thought about the chain oiler and I wondered if it was an adjuster for flow rate. But, the arrows on the cap only go one way ?? I have a guy here in town Steve that has grown up in the tool rental business. He is my small engine Guru. I am going to pick his brain on this. I have never seen anything like this on a saw before and I have tinkered on my fair share.

Btw, the picture you have, shows two double ended arrows. Clockwise is increasing, ccw is decreasing.

Ah, you have solved the puzzle it is an adjuster for the chain oiler. I thought the arrows only pointed one way.

Finally got my rebuild kit for the Tillotson carb on the 041. Paid $8 extra for faster delivery. Took 3 extra days past initial normal status. First & Last time I choose expedited shipping. After a couple fits and starts on Hi/Lo jet dialing in she runs better than ever. I'm glad to have her running again it's a beast of an old school pre-nanny state saw. No chain brake and whatnot. If it was just me running it I'd put skiptooth chain on it. But, Josh runs it too so we will stick with low kickback chain. It's not like we are harvesting timber anyways
