The Haynes manual shows a very similar tool for the adjustment you mention- so could be.

Yes you're correct , it's for adjusting the mixture . But be carefull , you only need to make very small movement to alter it a lot .

Indeed it is, you will need a CO meter to adjust CO to 1.5%
If running ok I would leave well alone, very rare they need adjusting once set.

Its probably 15 years since I last adjusted one, but very small movements needed and a CO Meter of course. All MOT stations will have one.

I set up a carburettor years ago using a Gunsen kit. It seemed a bit vague but I guessed the result was probably a lot better than before just by checking the spark plugs after running for a bit. At the MOT it turned out to be spot on.
