So went out Sunday, took all my diagnostic stuff with me just incase. Well.... got towed back in. I was able to determine gas was not getting to float bowl. Tore the whole fueling system apart to find nothing. Checked vent, no screen in pickup tube in tank, anti siphon (operates at 1 psi), New Sierra fuel pump ( 4 psi output on bench) new Sierra water separator/fuel filter. Screen in carb clean. Tank is clean from refurb. Didn't find anything so I yanked timing cover to check fuel pump eccentric (was good) did find a sloppy timing chain that will get changed. I have another fuel pump coming. So here is the question...... my canister fuel filter was before the pump. Could that be the issue? I am moving it to after the pump to find out and will replace filter even though it has only about 10 gal thru it.
