What kind if fuel pump is being used....vacuum or electric.

Is ether being used for starting fluid?  If so you my be running several
revolutions on the ether and then starving for fuel because it is not
being supplied from  the pump.

Batteries can fail (ground out internally) from our engines vibrations
over time causing the electric fuel pump to quit....the vibrations stop
and the battery works again.

Vacuum pumps can fail because of a failed pump diaphragm...there can be
a 'catastrophic' diaphragm failure where nothing gets pumped, or there
can be a maddening chaffed diaphragm where the vacuum from the crankcase
that operates the pump draws fuel through the diaphragm and floods the
crankcase.

I takes 3 things to make the engine run....Fuel, air and a properly
timed spark.

Subject: [F500] Re-firing rebuilt 494--Update

Hello all!!

Thanks again for all of the ideas on re-firing the motor. 

Out of semi-desperation, I installed 2 brand new carbs on the motor. It
seems to have helped, but it's still not starting and running. It's more
consistent about firing through 2 or 3 revolutions before it stops.
Different throttle settings and different idle air mixture settings
don't seem to help or hurt much.

Has anyone seen a similar situation?
