My 73 did not have an ac high idle solenoid. The solenoid was used for anti-dieseling. The wire is hot when you turn the key on to sets the idle speed. Once you turn the key off it allows the throttle plate to close all the way to eliminate dieseling.
I have since changed to a Holley carburetor along with other mods and set it up as an ac high idle solenoid.

The 202 was for the L-48 engine and the 212 for the L-82
That's correct- there's no interwiring for an additional A/C function.

Here's a link to an old posting with a photo. Gives another part # as well.

BTW: Does the throttle return spring appear to be connected to the wrong side of the throttle lever? Should it be attached to the lower side, pull the throttle back to idle?
This one may still be available...

nice. love it when you can find oem. that spring looks fine. as long as its not binding on any linkage....most will use a double spring for safety/reliability though. i dont like the springs that i see some guys use that go forward from the throttle linkage to help pull it back....JMO. the spring is there to insure the throttle returns to closed and wont be stuck at WOT

Mine is connected to the lower portion of the throttle lever, pulls it to idle.
Just an observation...

Yes I was.
It appears the spring is connected to the throttle cable, pulling it back toward the firewall. This is a pull linkage, pulling back on the cable opens the throttle.
I most often see the spring connected to the hole in the throttle lever, below the throttle shaft. This would pull the throttle towards idle.

You're right, it's just the way the photograph was taken making it appear to be connected to the cable. It's actually connected to the lower arm of the throttle as it should be.
