Quadra Jet with electric choke. IIRC it came out of a non AC truck so it does not have the selenoid to kick the idle up with the AC. Is this a simple retrofit plus some wiring to control it or a major modification. Making my winter project list, tired of idling at 10-1200 so the engine doesn't stall when the ac is turned on.

That depends on how the bracket for the solenoid attaches to your carb.





Got a photo of your carb?

There are two different mounting brackets, one for early carbs beginning with 70 a one for carbs beginning with 170. Both are easy to install and most are wired to the compressor.

I think someone told me this was a carb out of an 82 truck. Wiring to the AC won't be problem. Here are pics of the carb. I know the engine is dirty....another winter project.

You should send that picture and the carb number to Lars, I'll bet he can suggest the correct bracket.

The carb number is 17084289 1994 HKF

Fab up your own bracket or get one out of a junk yard, you can see from the pic posted by peterbuilt how it should look.

Ken, use a solenoid for a late 70s Q-Jet. They're designed to use the two bosses just above and forward of the primary throttle bracket.

This is an older picture(before I rebuilt my very first Q-Jet!), but shows what you should see:

That's an '84 truck carb. Your carb requires the idle solenoid that bolts to the driver’s side of the carb. There is an earlier version that snaps and locks onto a casting nub on the forward side of the carb, but you cannot use that version. Here are photos of 2 different solenoids that both would work on your carb:

This one is a later-model style, identified by the Torx screws and the short solenoid:





This one is the more common earlier version that would have been used on a Corvette. Note the slotted head screws and the longer solenoid:

If you decide to go new here are some part numbers. Some are long body solenoids some are short. I have used both on my car and both work. Make sure you get the correct mounting screws.

Tomco 8132 (Long)
Carter 213-157 (Long)
Standard Motor Products ES110 (Short)
ACdelco 2142138 (Short)
ACdelco 19190917 (Short)
If you do a e-bay search using 1997461 other manufacture part numbers are also correct.
