HELP
I have a 1987 Carb. B2600 Truck. I recentlly had the head replaced at the dealer.

Prior to this the head gasket blew between two cylinders, but it still ran fair and idled good.

Now the truck does not Idle.
Fast Idle works great, the truck runs great but once the engine warms up it stalls at Idle.

If I hold my foot on the gas at 800 to 1200 rpm's it has a slight miss. When I take my foot off the gas it stalls instantlly

Adjust the curb idle screw on the right side of carb- still stalling to the right of the curb screw is the A/F mix screw, close the screw and back it out 2 turns, now readjust the curb to idle specs.
