  • Rochester Varajet 2 carburetor carb problem?

    My 1983 Chevy G10 van with a 4.1l 250 6 cylinder, my van will start and run but at around 25 mph the van starts bucking and then sometimes die. If you pump the gas and put it in neutral real quick, it will recatch and again you will be good until about 25 mph. There is also a lot of carbon in the exhaust as it is running rich.

    Could it be that it is not just the carb?
