Sounds like your throttle idle switch is working normally.  On my 85, the
leads from the switch terminate on a connector socket attached to the
bracket holding the transverse metal coolant pipe that runs over the top of
the engine.

The switch is at the bottom of the throttle assembly.  If you look directly
down on top of the block right just to the rear of the throttle, you'll see
two small hex screws.  One adjusts the position of the switch; the other
secures the switch assembly once it is adjusted.

Whether you have a combined switch (idle/full open) is beyond my limited
knowledge.

> Yesterday, I got a multimeter and put it across the obvious connector
(throttle side of connection) that leads to the underside of the throttle
body.  My guess is that it leads to the elusive combined switch.  The
resistance was about 5-ohms when the throttle was in the idle position, and
had infinite resistance when the throttle was open.
