id leave it alone and just pust a new stocker pump on ... the electric pump will also need a regulator and it will make you go faster because youll have less money in your wallet slowing wieghing you down ,,,,
Oh yes defiantly would need a regulator with a carburetor.Remember the carb only has a needle and seat to stop the fuel flow from the pump.And it only has the pressure from the float and it's leverage to do it.So if you have a pump putting out 5 lbs. of fuel pressure and your float assembly can only hold back 1-2 lbs you will have flooding problems.
