Best Mechanical Fuel Pump

Hard to belive it's the same problem with 2 different carbs and not the pump and only does it after WOT. Both carbs are Demons and floats are set correctly as per FBO instruction on carb one and the engine shop on the other.

This isn't a regular occurance but dieing in mid traffic while leaving a trail of smoke and trying to get a flooded out car started still sucks.

When the pump was sold to me I was told it was ported/polished inside as they never flowed from factory the numbers they claimed due to casting flash etc.
