Whats the largest cfm/jet combo you tried on gas?
I have had my 850 Q/F up to 78-86.. It runs run fine there but it is way to moody to the air change.Around here you may see 1800 da to 4500 da in a days time. Not good to keep up with bracket racing. and they tell me my Q/F= quick fuel carb flow 930 cfm

my guess is that fuel starts to come through the boosters at 1300 rpms thats why the mix screws do VERY little change.
Really not a prblem but if its a street car it can be difficult to get the mix perfect throuout the circuits.
No street car and it seems to idle fine..Might be one of them things I am looking at to fix and it's not really broke LOL

Jones just wonder if I should be albe to ajust the Idle mixer screws at 1200 rpms ? I thought I should ? and if the jetting and air bleeds was close ?
The throttle plate is open to far so it's past the idle circuit. Are there any holes in the throttle plates? If not try opening the secondary plates and closing the primary some. If that doesn't work you may need to drill holes in the primary plates or if it has holes they may need to be larger. This is so you can get the air flow needed but still keep the plates closed enough to use the idle circuit.

This what I thought. But I am not not a great carb guy so I thought maybe I needed to change the IAB or something like that. drilling the holes is a old school trick I have done to older carbs that did't not have adjustable air bleeds.

You can make the circuit richer or leaner with the bleed but if the throttle is open past the transfer slots it won't make a difference.

This is how my 850 is setup...
86/95 4.5" PV - 50cc pumps, Brown Cam's and 54 squirters.
.026" HSB
.043" IFR
.081" PVCR
.067" LSB
Definitely lockout your distributor aswell...
wow you are really dumping the fuel with the pump/squirters. makes me fell better about bumping that all up. carb cam with orange cams and 37 squirters. Car would not leave the line went to pink cams and 42 squirters that help. So I got 45 in there now..I might need to go more !

has IAB .067 and HSB .028. So does this sounds close ??
Yes, that sounds close. But every combo can be slightly different.
The metering blocks and boosters will effect the main jets and air bleeds needed. Smaller on both air bleeds might help. From what I have seen, richer WOT might be worth trying, those 84/94 jets are not big for E85.
