Quick Fuel 750 mechanical secondary carb. Came off my V8 Pinto because the new motor had one one it that was already dialed for that combination. I have restored it to what is basically the factory stock condition....the only differences being that the secondaries are a 78 jet instead of an 80, and the squirter nozzle on the primary side have been increased by one size from the original #31. Great carb and I have been very happy with it. The only reason I'm selling is because it is now redundant.
