Engine continuously stalls until hot.

Cliff Ruggles:
1977 California carburetor.  Pretty lean carburetors for what you are doing.  Sounds like it wants more fuel just about everywhere.  Any idea how it is set-up?.....Cliff

When it fires the flap goes way beyond where I set the pull off.  This engine vacuum pulling flaps open?

What's the fast idle speed?

I would expect the choke coil would have released the choke LONG before the thermostat opens.

3/16 seems "rich"; but it could be correct for your carb.

Any chance the engine is dying from too much fuel instead of too little?
