You need more accelerator pump volume
you need way more timing at idle
you need to hook up a functional PCV and vent the other valve cover.
you need way more rear gear
you need a minimum of a 10" 3500stall converter.
Remove both carbs and flip them over and look at the throttles.
Reset all the throttles so that the idle transfer slots are just barely exposed under the throttle blades on all 8 barrels. (.015-.030")
Reinstall the carbs don't upset the throttle preset.
Hood up a PCV hose to the base of one or both of the carbs hook op the PCV to one of the valve covers vent the other valve cover.
Lock out the ignition timing mechanical advance curve so that you have 36deg of timing at idle and all the time.
Set the timing at 36deg BTDC at idle.
Should idle at 800rpm when fully warmed up.
You should not have to touch the throttle idle speed setting from the baseline preset (all throttles the same with just a slight bit of the idle transfer slot exposed under the throttle blades) . Re adjust the idle mixture screws slowly and evenly as nessessary for best idle.
You can now use ported or full manifold vacuum for vacuum advance. Limit the vacuum advance to 12deg.
you will need larger accelerator pump shooters (.035" or bigger) and maybe even larger 50cc pumps. jetting my need to be adjusted.
get a 4.10 or 4.56 ratio rear gear and a minimum 10" "3500stall" converter.
your idle speed and quality and throttle response will be much better after doing all these changes.
