Do you have a fuel pressure regulator in line after the fuel pump. These
carbs only need a few pounds of fuel pressure and the floats may not be 
able
to shut off anything over 4 or 5 lbs pressure.
A proper fuel pump ( not electric ) might be your first cure. Check your
choke flaps to see if they're working right.


I don't have a regulator after the pump-if I can get one, what PSI do I want 
one for, or one set to?

Thanks!
