Does it feel like it has compression when you crank it? Sometimes rings have burrs on the edges but, I’d suspect a fuel flow problem. Trace the pulse passage. Did you get the cylinder base gasket on right? Maybe a crank seal popped out, it happens. Do you hear a good base pop when you crank it with the spark plug out?
