I switched to a Carter YF too, awhile ago. And I am very happy with its performance. All except that it still overflows and boils over at shut down. I know it's the quality of the gas we can get now, but I read here somewhere about modifying with an overflow capture system? We, the truck and I, live at high altitude, 7000 ft msl,
so that might have something to do with it, too. I have been searching posts about possibly changing again to Holley or Weber, but have not decided what to do next. But I agree that the Carter is an improvement over the rochester!
