After sending Lars photos of the replacement carb currently on my car, he suggested replacing it ASAP. It is a badly configured rebuild that is in sad shape!
I was contacted by an NCRS member, having the correct carb, albeit a service replacement manufactured in 1975 (my car is a 72).
Lars took a peek and determined that it is an unmolested Rochester worthy of his attention. I purchased the carburetor, knowing that once Lars works his magic, it will be much better than the bootleg Q-jet I'm running now.
I'll continue to search for the date correct carb, but in the meantime, I'm packing this up and sending it off to Lars.
I know I won't be disappointed.
I am reading through Lars' shipping instructions. He indicates that the idle solenoid should be removed before shipping.
Forgive my ignorance, but my existing set-up does not have one, nor do I see a location for one on my newly acquired replacement carb.
My car is a base SB, 4-speed, non-AC model. Do all cars have an idle solenoid or just AC cars? Am I missing something?
Learning as I go.
Just contact him via e-mail { V8FastCars@msn.com } and tell him the carb configuration you now have and also how you wish the rebuilt carb to be configured. If you don't need or want the idle solenoid, he should be able to leave it off. If, however, he recommends that you should have one installed, he might have the parts needed to do so.
But, you should discuss all that with Lars....initial contact being via e-mail.

Check your AIM and Service Manual for your car's configuration. The carb itself is configured for a solenoid and bracket - all 1972 Q-Jets are. The solenoids are not for AC - they're for anti-dieseling control after engine shutdown, and most cars were equipped with them.
Okay. Checked the AIM and the service manual. Neither have a real clear illustration of the part/wiring etc. The service manual does explain how to adjust it though.
If anyone could share a photo of it in place with the wiring connection it would be of great help. I looked at the car last night, and found a single, brownish wire folded and tucked up under one of the chrome ignition wire shields. I have a suspicion this may be my idle solenoid wire.

The idle solenoid, installed on the carb, looks like this:
Solenoid with bracket:
Solenoid. This is what is known as the "long" solenoid, which is correct for your year. There are also "short" solenoids, sold as replacements, even though the "long" ones are still available:
The brackets are available as new reproductions from Corvette Central and other suppliers - their part number is 353126 for $16:
Installed on the engine with the tan wire hooked up (I don't believe this wire is routed "correctly," but it gives you the idea):
All the major Vette parts places carry the solenoids as well, or you can get one from your friendly parts store under one of the following numbers and brands:
Tomco 8132 (Long) Carter 213-157 (Long)
Standard Motor Products ES110 (Short) ACdelco 2142138 (Short)
ACdelco 19190917 (Short)
The CF comes through again!
I tested that brown wire, bingo! Power with ignition on. Didn't even know it was there tucked away like that.
Thank you again Lars! Your photos and info will help me put things back the way they should be. This carb is coming your way soon.
Settled on this Quadrajet
