fuel filter puzzle

[Brian Young]

Earl, Ive had the same problem. Usually a hesitation
coming out of a long idle, especially on inverted
stuff, you think it has died and then it pops and
goes. Sometimes blows a cool smoke ring.

What Matt said is correct, needle setting. You really
want the filter before the pump cause stuff in the
pump is bad. Maybe by moving the filter ahead of the
pump you dropped your pressure slightly more than
having the filter between pump and carb, thus leaning
the engine a bit more.
