The carburetor on my 83 Ford F150 truck has two screws (one red and one
green color) that adjust the idle.

My truck is dying when I take my foot off the gas.

Will you please explain what is supposed to happen if I adjust each of
the screws in either direction?

Thanks,

Russ

The two screws adjust your air and fuel mixture to the carb.
You can lightly seat them and then come out one and one half turns and see
how it's running.
At least you will have a starting point.
Adjusting them will smooth out a rough idle, but if it's stalling when you
take your foot off the pedal, it could be a number of other things.
