Does the manual chock carb on a 1979 4x4 20r have any wires going to it at all?
Shouldnt if its manual....
it did have some wires going to it but someone added a manual choke. Im looking at replacing it.
the wires look like they go to a condenser or something?
Post a pic
this isnt my carb but this is what im referring to.
got home and looked it up and its a solenoid but im not sure what it is for, is it the choke? the choke is up higher though thats what has me wondering
That wire cuts off the carb. when you turn off the motor. The choke is automatic controlled by the two water pipes in the rear, adjustment is by loosening the three JIL screws (look like Phillips head) and moving the device back and forth note the marks of reference on the top. Watch the choke plate to see which way to go.Do not touch the bolt in the middle or it will leak.The fast idle and choke are controlled together here.
The part circled is the idle fuel cut solenoid... or anti-diesel solenoid.
Turn the key on and it clicks open allowing fuel to flow through the idle circuit.
Turn the key off and it clicks back into place, blocking the idle circuit.
It's there so your truck doesn't keep running when you shut it down (anti-diesel).
Separate names with a comma.
