    Shouldn't the idle stop solenoid have 12VDC at the electrical connection when the ignition is on and the engine cold ? I am not measuring any voltage when cold, and I am having "fast-idle" problems. I have oiled the throttle linkage, and just put in a new idle stop solenoid, but the plunger is not plunging ! Any suggestions ???
    Also, the green wire going to this solenoid disappears into a wiring harness, but where does it originate ? I'd like to check for continuity...

    thanks !

    try running the A\C, that is what it is for , to bump up the idle to compensate for the load of the A\C compressor

    Yep, Eagle86K5 pinned it ! Thanks ! Turning on the AC energizes the solenoid. Also, I used Berryman "B-12 Chemtool" to spray clean the carb and throttle linkage, wow !, what a difference ! My idle is awesome right now, I guess the linkage was pretty gummed up. Anyways, thanks for the help !!!
