Fuel vaporization fix

Bewy said

You need a phenolic spacer under the carb. That will reduce heat getting to the carb which will in turn reduce the amount of evaporation. You do not need any other vent lines. The carb has atmospheric events for each float bowl which allows the fumes to go the atmosphere via the air filter.

I've seen those recommended. Which is worth looking into. With the mechanical pump, I figured it was cavitating due to vapor. But with the electric, it should push the vapor into the carb and vent it out until it gets enough fuel to shut off the bowls, right? I would think that would happen fast enough that I wouldn't experience any drivability problems. So maybe it is just boiling in the carb itself?
