Welcome from Montana. I, too, am a Q-Jet man. I've rebuilt several & have had great luck with them. Make sure you check the play on the throttle shaft, because if it's wore out, it'll suck in air and to my knowledge, you'll have to ****-can it. The carb numbers on the side tell the story, including the build date. You'll also need them to purchase the correct kit. CLEAN IT WELL!!! I've used laquer thinner and an old toothbrush in the past, but you can degrunge the bulk of it with a spray can of carb cleaner
