Are the slides rising and falling smoothly? Are the diaphragms good, without any buckling or rips?

Are you certain the idle mixture passages are clear, and the screws have good o-rings and springs/washers positioned correctly?

Collars/Needle Jets in-place?

You may still be too rich with 110 Mains.
with 110 it was white smoke and 120 it wouldn't rev and was spitting. 115 was the spot where it was a nice consistent rev with no plug fouling. if I let it idle for long enough it will make the spark plugs black.

The slides do rise smoothly. they "bounce" a little at idle like move up and down really quickly ever so slightly. not sure if thats normal. the diaphragms are in good condition

and yes the collar needs are the right way around. I learned that problem working on my other bike. having those the wrong way around makes the bike run crazy
