Thank you for the thoughts thus far. This is where I am now.

does it with engine cold or hot
has about 4-5 psi fuel pressure
floats and float levels are good
tested needle and seats and they are good
plastic body not cracked or warped
epoxied jet bowls are good, no leaks

could the gaskets / o-rings for the 2 aluminum tubes from the upper aluminum top that seal next to the jets in the plastic body cause flooding over??
