Hi Jan, are there springs or O-rings on the needles? I need to check what type carb that uses.
If there are only the threads holding/sealing some type light thread locker would work, like loctite “elastic”.

looks like springs from the rebuilt kit. I would probably put a carb rebuild kit in it. or a just a new carb, which appears to be like 20 bucks.

I see no O-rings or springs around it other than the threads, but it’s a saw I got from my neighbor, so I don’t know what it looked like originally.
I’ve also looked at a new carburetor, but became a little hesitant this spring, when my neighbor asked if he could borrow the saw back now that it was working

Well, can’t say how this is set-up, but some saws the needles “rely” on the rubber plug that seals the air-box from the outside where the needles could be adjusted.
If using pump gasoline this rubber shrinks and becomes hard, not holding the needles in place. This also happens to the rubber with time, more plastic mixture in rubber nowadays, bad, bad quality.

I don’t know Jan, but it seems your neighbor is bordering on what we used to call an “Indian giver” before the days of politically correct language.

I have loaned out several chainsaws over the years that came back non-functional so no more mister nice guy. Pretty much the same with any tools. Especially to my family members. Been a long time since I cared if anyone liked me or not. The dog and my wife do, I think. That’s good enough.

They don’t show an o-ring or spring on this parts diagram for the adjustment needles, however, it almost looks like there is one according to the picture or the shaft is rubberized. It possibly means they don’t sell the o-ring separately.
