97 Carb Fuel Bowl

[Bulligen]

I am going to do just as you guys have suggested and set up a gravity fuel source tonight and see what happens. The old original carb did the same thing as the new one that is why I though I would just buy new instead of rebuild? Could the electric fuel pump be drawing air and fuel from the tank at the same time therefore always having fuel with voids of air in the lines. The inline fuel filter which is standing upright in the line going to the carb is never full of fuel at best it is 1/3 full. Also as the engine stumbles and dies, right at that moment I can view a surge of fuel through the filter going to the carb but too late to keep it running ??
