Evaporating Fuel in Carter 4-Barrel Carb?

the eddy/carter accelerator pump is located above the bottom of the fuel bowl...the bowl could still have gas in it but the pump is dry....hence car will not start ....

holley accelerator pump is fed at the bottom of the fuel bowl..it will provide a squirt of gas until the bowl is dry.....so the holley will last longer....

but as said...the gas today is lousy for a carb...

we use e85 for racing....on another web site people state that the gas will evaporate faster then the ethanol and raise the ethanol percentage...I have tested E85 that has sat for 6 month with an open vent in the plastic jug....the percentage was still at 85%.....
