Another vote for q-jet, but make sure of what you get, as there are different variations. In addition, I always replace the synthetic type floats in favor of a brass float. Many fight and toss perfectly fine carbs simply due to a heavy or sunk float, and I nearly did that same thing many years ago until someone familiar with them actually weighed the float, and we replaced with brass, and it was in the carb until I got rid of the truck years later. I just rebuilt one and due to the truck running propane, the primary throttle bores were worn out. Drill and bushing fixed and it runs fine.
