Other than what has already been suggested, about the only other thing I can think of to check and that might restrict fuel flow for the dry carb is if you have the optional ceramic element fuel filter next to the carb, the ceramic elements have been known to get varnished up from fuel evaporating in the glass bowl and then clogging the pores. They will let a bit of air pass if you blow thru but fuel is kept to a trickle. There is also a fine mesh screen in the fuel inlet at the carb. It is either in the inlet fitting or under a large hex plug just behind the fuel inlet.

If the gas tank has tiny rust particles floating around there is a screen in the bottom of the fuel pump which can get clogged. If you disassemble to look at either the fuel bowl at the pump or the glass bowl on the ceramic filter, you will probably need new gaskets as the old ones usually take a set and will leak once removed and then put back together.

The 6v at the coil when cranking seems a bit high. With the amp draw of the starter motors, typically it falls a small amount and may drop to about 5.5v with a 6v battery. Are you still on 6v or has the car been converted to 12v and is there a ballast resistor in the coil supply circuit?
