GSP7:
Is this a false statement about the mid '80 Carbs with the solenoid ?

Posted on a Chevy forum: below




--- Quote ---In the early ’80s, GM incorporated electronic connections to the Quadrajet. The Quadrajet’s primary circuit had a small solenoid installed to control the depth of the primary metering rods. These Quadrajets are difficult to modify for conventional use.

Ive never had one of those carbs with the solenoid, so I dont know what is inside. I thought I read here that you could just remove the solenoid stuff and its a good carb like the late 70s 80 carb..??

How does that solinoid control the metering rod? and APT? Any pictures of the inside?

Kenth:
Other than original use for the Computer Controlled Carbs i would not spend any time on these.

JMHO

quadrajam:
The carb in the image above is OK. 85 and 86 truck carb. The solenoid connector is
grey as shown.

The ones to avoid as Kenth says are the computer controlled..CCC carbs.
They have a blue or black colored solenoid connector and also another electrical
connector on the driver side down low. Started in 80 or 81 on passenger cars
and continued till fuel injection.

So sounds like you are saying the one in the above picture is a good carb to use


. ???

Kenth:
Just remove the "Dual Capacity Pump" solenoid and it will function like any other Quadrajet.
