The carb only has idle adjustment screws on the primary side. Secondary throttle plate is closed 100% at idle. Took the primary screws in all the way, backed each one out 1/2 turn and hooked up a vacuum gauge. Increased the idle screws until I achieved maximum vacuum, then backed each one in a hair to drop it 1 hg of vacuum....kinda tough because the vacuum is not steady....the needled bounces and fluctuates around 1-2 hg, but is strong around 21 hg. The car idles fine...just a bit of a lope to it. There does not seem to be any miss at idle....only when cruising with minimum throttle, if I down shift and kick the RMP's up the stumble/miss goes away.
