I also had the same symptom of low gas level in bowl. Turned out to be varnish in the ceramic filter element. Car ran, element looked clean & could blow thru and seemed clear but apparently not clear enough for much gas flow. As soon as I changed it, all was well.

Not unexpected. Lacquer thinner or ethyl acetate if you find it at your local paint store is an excellent solvent for gasoline varnish and do a nice job of cleaning carb internals as well as the ceramic element of the filter. But while the filter is out, I'd suggest flow-testing the pump.

Changed the coil & condenser Saturday. There was was a lot of soot in the coil wire socket. The old condenser was made in Mexico, the new in the US. Took her out Sunday morning and ran at 55-60 for about 20-minutes. No problems at all. Ran her hard that afternoon also. The engine is still not real smooth, I'm pretty sure I have a compression problem in one cylinder. That plug is always sooty.
The other thing I did was take the ceramic filter out of the sediment bulb like someone had suggested. I soaked it in brake cleaner and then blew it out with 150 psi air. The sediment bulb is now nice and full right to the top. Excellent suggestion guys!!
