55.2 3100 235 Rochester B carb. With the air filter off, I can adjust the A/F screw out about 1 1/2 turns runs fine(idle). Put the air filter on it dies. With the air filter on I have to adjust the A/F screw all the way in to make it idle, and as soon as I take the air cleaner off it dies. Air filter is new, I even tried one of those cheapo chrome air cleaner filters, same deal. Truck drives down the road fine, starts fine, last trip I got 15 mpg, which I think is good. Any idea?
TIA.
