My King Quad was running fine and then decided it wouldnt crank again. I can spray fuel into the carb and it will crank and cut off. I removed the fuel line and could blow thru the line into the tank but couldnt pull any from the tank, also I removed the top of the carb and pulled what looks to be the diaphragm out and sprayed cleaner into the carb, placed it back and again it fired for a couple of seconds and cut off, it would only idle, couldnt throttle it none. everytime i messed with this it would idle for couple of seconds and shut off. other than that it will not crank at all.
