Does the low speed adjustment (not idle but mixture) screw meter air or gas? When you turn the screw counter-clockwise, does it get richer or leaner?
Thanks,
Fred

It meters air. Unscrewing (counter clockwise) will let in more air. This leans out the idle mixture. Screw it in (clockwise) to cut off air. This will richen the mixture.

Thanks Vince. I'm glad I asked because that's just opposit of how my scooter carb works. Now all I have to do is keep it straight in whats left of my mind about which bike I'm working on.

Might prove useful as Mikcarb is the Indian (built under licence) Mikuni!

Works the same way on the CMW flat-slide carb. I was used to the old type fuel mixture and screwed it up a bit. My mechanic buddy educated me. It was the last step I had to take to really dial in my bike. Runs almost too perfect now

Oh no! Dangerous time!!!!!!
I usually find that just when I get any mechanical piece of equipment about perfect it goes 'bang'. All the while there are tiny outstanding niggles/things to do it's OK.
All perfect? As the song says "There may be trouble ahead........"
Hope I it's just me and not S*ds Law in action eh?

Worries me too. Especially now that winter has set in and I will be wanting to tinker more often than ride. Guess I'll just have to invent some things to do to it, like new tires, or heavy duty clutch springs.

Easy way to tell at a glance is if the screw is nearest the engine it is fuel adjust.If its back by the filter side its an air bleed.
