Oh, I should mention also my fuel pressure gauge, when working correctly, sits nicely at 6psi. When not working correctly (the time that I notice idling issues), it sweeps violently between 6psi and 15psi. I think this may be a problem related to air in the fuel line?



Okay, let's review:

1. When the fuel pressure gauge "is working" (6psi), the car runs well.

2. When the fuel pressure gauge "isn't working" (spiking to 15psi) the car doesn't run well.

3. This is the second carburetor you have tried on this car, the first one having been pulled because fuel was getting by the needle valve & seat for some mysterious reason.

Have I misstated anything?

Down to just a blue car now.
