Hi Dan,

I would have your whole fuel system inspected, and possibly redesigned if necessary.

What fuel pump?
How much fuel pressure, do you have a gauge, has the pressure ever been measured?
Does it have a pressure regulator?
Filters pre and post fuel pump?

And as Chris has mentioned above, more than likely a delaminating fuel hose near the carb, that line debris is jamming a needle off it's seat.

Seen this too many times to count.
