Idle circuit tuning.
Heated intake helps. Most of us don't have heated intakes though.
Initial ignition advance setting is just as important as the carb tuning itself.

Yes, Really helps when you are running a long duration camshaft. Thats one of the nice thing about some of the new programmable ignitions from Daytona sensors, msd, etc. You can have lots of timing at idle, bring it back once off idle, then bring it back in gradually, or quickly, or based on a map sensor value, etc. Locked timing is cool for idling, but on certain setups, can really cause issues.

All depends on booster design (annulars will start sooner), throttle bore + venturi size, air bleed size, and throttle opening. vs the airflow which is determined obviously by engine cid, camshaft, cyl head, intake manifold, throttle opening , exhaust and etc.
On the same engine, A smaller throttle bore/venturi carb with annular boosters and smaller air bleed will start flowing fuel a ton quicker than a huge bore/venturi with larger bleeds and say a dog leg booster.

Anyway, I enjoyed the read guys.
