Okay, good suggestions. I'd use a vacuum gauge on full time manifold port and tune the idle mixture screws for best (highest) vacuum reading.
Adjust curb idle for 900-1000 rpm, readjust mixture screws.
Loosen dist holddown and adjust for max vacuum reading. Use timing light and check timing. At this point, retard timing by 2*. This will prevent a slow starter when engine is hot.
Readjust curb idle to 900-1000 rpm. try a WOT blip to see if engine does not cough, stumble, but, picks up in rpm.
You shaould end up with 28+-32* of dwell, 4* BTDC of base timing at 900 rpm. Sometime this doesn't always work. Alittle more base timing is needed.
Check the venturi boosters in the air horn of carb. If they are dripping fuel, fuel level in bowl is too high, or fuel pressure is too much, highly unlikely. This will make for a rough idle. If level too high, loosen the locknut, hold the large screw, and turn nut CCW to lower the fuel level. There will be fuel spraying everywhere if engine is running.
Drive it up to the Beach, I'll work on it........
