Default demon 750 adjusment

Just rebuilt this carb and it runs good, but it won't idle when in gear unless
neutral idle speed is better than 1300RPM
I've started over from square one several times, rich or lean, idle is way low in gear. Any words would be appreciated.

70 Challenger
440

check for base gasket for not sealing. spray a little carb clean around it and see if idle picks up. does it have vacuum secondarys the rear could be open to much have seen that on many holleys carbs.
