Tell us, in detail about your fuel system.
Pick up line ID
Any anti-siphon valve ?
Fuel line size throughout - all parts
fuel fitting type and size ID
Fuel pump man/part#/type
If you have a regulator the man/part#/type
Water seperator - housing fitting size and where placed, before or after fuel pump.
Any other filter in system ? Where ? What man/part"/type
If you have an electric pump how far below the top of the tank is it ?
So............every little thing that has to do with the fuel.
You seem to definately have a problem with fuel supply and/or carb so let's attack this. If the system is all in check then you can get good avice from Mr Carburetor ie: Rumrunner.

So the frothing was something restricting the volume, yet psi was good? Interesting. I'm still having a hard time with this. If the volume is too low, the needle and seat will stay open because the fuel bowl is not full. Therefore the pressure should drop. What am I missing in this picture? Keep the discussion coming.

Rum -
6 psi from a 1/2 inch line will produce more volume, than 6 psi from a smaller line, such as 3/8 inch line. Or, the larger fuel line will pizz out a greater volume of fuel than the smaller line, if the psi is the same at both lines.
That what you're saying, Rum ?
