You've already verified the solenoid is fine. It clicks which means it's opening, and you said it sprays fuel out, so it's flowing, it's doing everything it's supposed to. You will only get a spurt after pumping up the bulb and then pushing it in. As soon as the pressure drops down, it stops spraying fuel. I ALWAYS crack the throttle open starting these old loopers, just makes starting easier. If you hold the key in to prime it while cranking the engine, the fuel pump will make pressure and let it spray more fuel in.
