If anyone has a spare, we have a TWOA member who isn't on the list who is

searching for one. If you have one you'd part with, email me and I'll put you

in touch with him.



Thanks,

Edelbrock makes one (#8059).  It's not bone stock, but I bet a little

engineering could make it work.

I had increased the idle speed to somewhere around 1k/1100 RPM's on my a/c 75.

Worked like a champ.  I think I took the throttle speed jack off as it was

inoperative.  Come cooler weather the revs were decreased to 700 RPM's +/-.

Hokey Smokes, Bullwinkle, Maybe I should look for one in my pile of jun...miscellaneous parts.  Also, I suspect most of these are designed to keep a throttle open but not quite up to the task of actually opening a throttle.  The look to be quite a bit smaller than the OE part and, hence, develop less force.  Using such a unit one would see that when the AC is turned on at idle the engine speed will not increase but drop due to the increased engine load.  Only after the throttle has been operated by the driver will the engine idle back down to the desired, increased speed. Certainly something with which one could live but a little bit inconvenient.



My '79 Mustang had a vacuum motor device that did this and it worked great until the diaphragm failed.



Here's one for a Cadillac:

You will also need a solenoid valve but those are easily had.
