Amal adjustment questions

My '74 850 wants the choke when starting. More so than I think is appropriate. Here's the scoop..

Cold start - tickle and full choke. Back off choke after a minute. Idle is stable.
Luke warm start - full choke. Back off immediately after starting.
Hot start - no choke.
Extreme hot start (this Summer it's been HOT) - no choke, but need 2-3-4 kicks. Very annoying. This is what I'd like to correct.

I'm also averaging 59 miles per US gallon. Seems a bit out of normal. Needles are at 2nd notch, mains are 260.

I adjust idle air mixture screws such that I don't get a backfire or stumble when blipping the throttle. They're at about 1 turn out now.

Idle is stable (probably due to TriSpark ignition) and throttle response is OK, tho not spectacular.

I just bought a pair of Stay-Up floats and I'm considering raising the level a tad above what I have now, figuring that it's lean across the range. Does this sound like a plan?

Thanks

Seems ok. I think some people would kill for a start process like that.

Have you adjusted mixture screws as the manual, one carb. at a time?

If your mixture screws work best at about 1 1/2 turn out, the floats are right. I found the factory float adjustments to lean for mine, it would hardly tickle and starting was really hard. When I increased the float height to my old plastic height, it worked fine.

Its very slightly tuned lean of about optimal, with needs chokes or tickle to start cold and maybe even hot, but with more open throttle. With 1 turn out pilot which is cutting down air, I'd suspect float a bit low as mentioned too. Low 50's mpg is most common Commando mileage. My buddy Wes just raised his Miki mouse need and dropped from 55-56 mph to 47 and didn't feel any change in performance.
Never ever forget that factory Amal slides are a wear item like tires and become leaner running as they season with use.
