Okay, slight improvement. Found TDC for #1 and sunk distributor post with rotor lining up on #1 plug wire in the cap, fired immediately. To get it to idle somewhat smooth had to retard distributor to the point where the hold down lip on the distributor housing is off the hold down area on the head; that can't be right. On the road test the car performed slightly better than before. Am convinced this is an ignition problem rather than carb. Plug wires are 8mm Taylor for electronic ignition. Will clean all the plugs tomorrow and try agin.
