Crank but no Start problem

[Steplift 72']

Since it cranks right up when you squirt in fuel, maybe you've eliminated the ignition system. What could be keeping the carb's from delivering fuel when cranking? It could be anything from compression (not as likely) to fuel pump, carb's or filter. Having said that, I've seen 2 motors that would not start cold without a squirt of fuel or starter spray after they were getting well worn. Remember that a hot motor doesn't require as much fuel to fire up.

I had similar problem and the culprit was a dirty fuel filter in the pump itself.
