Carburetor trouble

What do you mean by fuel pressure goes crazy? If it's loading up under WOT I'd double check your timing and check rear jet size.
Fuel pressure consistently runs at five pounds in town and on short runs once I start accelerating hard on long runs the fuel pressure starts bouncing between 0 and 3 until something like the carburetor loading up and choking out and I smell gas then the fuel pressure goes back to 5 this continues to happen until I stop for a couple of hours then it’s back to normal with no problems
