UPDATE -- worked Thursday eve on getting the floats set , vacuum observed and idle, mixture screws adjusted, 34/12 timing, about 1000 rpm final idle. But, when taken out for test drive, it stumbled, stalled. If i'd floor it, it would haul A..! Couldn't drive it reliably, so I got home and removed the 6pack setup and am installing my LD340/carter 625 AFB again. What a dissappointment I have... I will work again on the sixpack as I want it back on and running perfectly... I'll have more time after this wknd is over from Road America.
To get a reasonably high vacuum (13), I ended up with the metering screws set about 2 full turns out. Isn't that too much? I have 62 jets in the center, and also light springs in outbourd vacuum pods. And, I used the clear see-thru plugs on the bowls (a little tricky to get used to... maybe I should've pulled them out to positively confirm).
Any suggestions?
