Put a pressure gauge on it and go drive it. Monitor the pressure when it
misses.

At steady acceleration to 4000 PRM in 1st, 2nd, and then 3rd the car 
runs smoothly. It runs smoothly in 4th too, although I can not quite 
get it up to 4000 RPM. It misses and lacks power under harder 
acceleration. The fuel filter is clean (but a small glass one), carbs 
are rebuilt, and the fuel pump is rebuilt although I have not tested 
the pressure. The gas tank is new and clean.

Original coil, but the distributor is rebuilt, good cap, new good 
rotor, new good points, new gapped plugs.

Seems like fuel starvation and not timing.

Any thoughts?
