Not pumping??

When it dies and won't restart,, get out and look down the carb,, work the throttle a few times,, seeing if it squirts gas,, if you see gas, go crank it,, see if it starts,, if it won't start and you definately saw gas, then, check for spark..

If no gas,, check fuel filter/pump, etc and all rubber hoses on the suctions side of the pump back to the tankfor kinks,,cracks, or loose connections,, somewhere it can suck air... take the gas cap off , listening for suction, ie plugged vent.,,

if no spark,, "search" - "no spark" lol

and yes, headers get sizzle hot in a few seconds, I've got scars to prove it..

hope it helps
