With out looking at your other threads, You're not going to re-create load on the trailer unless it's backed into a test tank. Replacement carb raises and eyebrow. Is it OEM? Is the fuel pump pumping to spec? Accelerator pump in carb comes to mind. Can you accel slowly to plane? Lot of variables.

New fuel pump raised pressure to spec. Replacement carb not rebuilt but symptoms stayed the same.
