Why don't you try this just for grins. While you are cranking the engine, open the throttle plate and squirt some WD40(not starting fluid) down the carb. It should run as long as you spray the stuff. If it behaves the same then I would look elsewhere. If it runs good then I would look at the carb or fuel pump.

Sounds to me as if the needle valve at fuel inlet is not moving freely - sometimes. I'd pull it and look for dirt/rust/bits of old fuel pump diaphragm, whatever. It could well be a new problem.

Some of the new replacement fuel pumps are known to put out too much pressure. I'm surprised they haven't warned you of this on the Ford Barn.

2 things. First, I recently purchased a NOS 1949 fuel pump still in the original box. On the box it stated that the unit is shipped with all the Head bolts lose. Referring to the 8 machine screw the go around the diaphragm. I doubt that it has anything to do with your situation but I thought I would point it out.

Did you inspect your float? It almost sound like you have a hole in it and it slowly fills up. Then it sinks and opens the needle valve and you get gas all over.

CraigerF100 is starting off with a positive reputation.
you mentioned you adjusted the float height, maybe knock her back down a notch and take another joy ride to the car wash
