Oh- never say never from experience. Especially if stuck closed.That won’t affect full throttle operation and it idles and starts well, I don’t think that’s his issue.

Here are pictures of every face of the carburetor with every marking I can find. There's also a cast "M22" on the face where the needle valve sits, but I didn't take a picture of that since it's internal to the carb. I suspect that the important ones are the stampings "WT 16B B7" on the face with the fuel line barb, but I'll let you be the judge.What is the ID numbers on your Stihl carb?
I would definitely be interested in carb manuals if you have them! I'm sure that would be helpful.great feedback there appreciate it.
the clutch looks very blue like it got super hot at one stage. could hit the outer flat ares with sandpaper and see if that color comes back.
i have super detailed carby manuals in PDF if you want them.
also that chain is super blunt from looking at those photos. but thats only half yr problem. the circled blue bit looks like a chamfer on the cutting edge.
that needs to go.!
Where is this valve located? Is it in / under the brass piece at the top of the carburetor near where the W is stamped in this picture? I know I get lots of flow out of there when I spray brake cleaner in the hole for the High speed adjusting screw, but I have no idea if it's the right amount.Oh- never say never from experience.

This valve is located in the main venturi nozzle. Some were rubber discs others were made out of woven fiberglass. If stuck open the saw won't idle with the correct carb settings. If stuck closed it will bog not rev up.Where is this valve located? Is it in / under the brass piece at the top of the carburetor near where the W is stamped in this picture?

All good mate, you mentioned stuck open which would flow fuel but won’t start and idle but it was, that’s all 👍Oh- never say never from experience. Especially if stuck closed.
The only Tygon hose on the saw is the vent tube. I used it to do the pressure / vacuum checks because I could thread it into the hose barb on the case, but it is not used for either the fuel supply or impulse line.1119 358 7700
some dumbaszz used tygon and its collapsed killing your fuel delivery, replace the fuel hose using the part # given. It can clearly be seen neing used in your video, if the impulse hose is tygon aka yellow/clear replace it with stihl hose too!!
Take it easy on him mate, he’s learning. We’ve all been there.Good lord that chain is fuked up! in a way that will result in it biting in and likely bogging down a underpowered saw. Ever try filing a chain? there are modern filing jigs sold by stihl and pferd that make it pretty idiot proof.
