If rapping on the carb bowl doesn't unstick it, then B4 you ruin a top gasket, you could try getting a can of Gumout carb cleaner, remove the fuel line, and using the red tube, try and insert it all the way to the other side of the airhorn. Maybe an extra squirt/blast of pressure against the needle valve will help loosen it or clean it. Good luck. Sorry to hear about your QJ dilemma. And EFIs are "illegal"
Wow. And lastly, say hello to ABBA for me.
