Short version: How do I turn that screw on the right? Difficulty: I have to be able to turn it with the saw fully assembled so I can tune the carb. Right now I can only see the damn thing because the starter assembly is off. You are looking at a flat round piece of steel, not a plastic limiter cap.
Long version:
My daily driver saw is a Dolmar 6400 with a stock Zama carb. Use it the most, like it the best. (Someday when bad things happen to the piston or cylinder it will become a Dolmar 7900.)
I lost several bolts out of the saw and the muffler was fixing to fall off, so I pulled the muffler and dealt with that. While the muffler was off, I thought it would be a shame if nobody drilled a couple strategic holes in it, so I did that.
Now I want to tune the carb as the airflow situation has changed. I got my trusty limiter-cap-pullin' drywall screw out and *clink* hit something metal. Hmm.
Can't see a thing, so I took the side of the saw off to get the rubber carb adjuster cover thing out.
Hmm, it looks like I am missing a part?
Or maybe the bastards did that to me on purpose.... argh
The part shown above is bad enough, mine is even worse and has a completely round smooth head.
I thought of reassembling it without the adjustment cover and tuning it, but that stupid screw feels completely smooth and round. I can grab it with hemostats but I can't turn it a whisker.
Even if I pull the carb it doesn't look like I can get a dremel wheel in there to notch it.
So... drill it out and tap it for a tiny screw? I worry about this because I think the drilling or the tapping will turn it hard enough to damage the carb, and I have no way to hold it while I drill.
Rip the top of the saw apart, pull the carb, and try to cut a tiny notch in it... maybe with a burr point dremel?
I know two or three of y'all have a better idea than that!
