With the air cleaner lid off, cross #1 and #6 plug wires at the cap (across from each other) make it pop 2 or 3 times with a quick rev, then put them back. I'd add a fuel filter right before the fuel pump and see if maybe the sock in the tank is clogged (vacuum gauge in a tee where you are adding the extra filter) Crud from the tank jams the inlet valve on the fuel pump open. Could also be water in the gas. Any Amsoil guys near you? I find the PI to be an awesome system cleaner.
