I have a 1971 Skylark with a stock 350 2 bbl. and auto trans. The car has an idle control solenoid for the carb. I bought a t/a performance stage 1 aluminum intake and a factory Q-JET carb. My question is should a 4 bbl. have the idle control solenoid set up? There is no place to mount the solenoid on the intake. I also got a new engine wiring harness and there is NO connecter plug for a solenoid. Does anyone have any photos showing how this set up should look.Thanks for any help Steveo No:
A stock 1971 4bbl intake would have the holes for the idle stop solenoid. However, an aftermarket aluminum TA Performance intake does not have those holes.
Pics of the Q-Jet set-up on my '71 350 stock intake. Harness used for the solenoid is an intermediate harness that was issued with the solenoid. It plugs into the engine harness connector that initially went to the TCS on the carb.. The kits were available from GM for early '71 cars build with a dashpot. Mid-year production saw the factory installed solenoids. Your biggest hurdle will be mounting it on the TA intake.
Thank you very much! These photos are exactly what i need. It's great to receive such great help from such nice guys. All responses appreciated! Steve:TU:
Hi Steve C, Do you have any choke photos for a 1971 Q-JET choke set up? What year is your engine in the photos? Thanks, Steve B:bglasses:
Steve, No separate choke pics & the car is away in storage until Spring. Using a factory divorced choke. First photo it is just barely visible. LH side in the picture. You can just make out the linkage & the choke housing under it. This intake is a '71 350 intake. The engine is the original to the car, '71, but was sold new with a 2V carb.. Previous owner swapped in a '72 4V intake, I found & put in a '71 . Thought there were a couple good pics of different chokes here.

I have this same set up on my '71 350 GS, auto trans, no A/C. I see that the TCS plugs into the wiring harness, but where does it go from there? Does it plug anywhere into the automatic transmission? Am I better off removing this set up? Thanks
The Transmission Controlled Spark circuit is completed when the trans is in 3rd gear. This will allow vacuum advance if the Thermal Vacuum Switch (TVS) is in the proper condition. The delay for vacuum advance lowers hydrocarbon emissions. It also causes the car to run a little hotter. You can bypass this with impunity if you have a smog-exempt car.
