quadrajet Qjet port identification and whats this ?
im ready to bolt my carb on but i wanted to make sure i IDd the ports correctly.
The front view shows what I think the ports are. PLease correct me if Im wrong
The back view has two ports im not sure what they are? I think #2 is related to the hot air choke (i installed an E choke) and #1 IDK what it is for. if i dont need these 2 on the back can (and should) i just cap them off?
The only thing I can't say much about is the rear-facing side -
One of those is definitely the inside-air-cleaner air feed for the hot-air choke, but I can't think of what the other one is for.

I believe #1 should be the vent line from the TCS solenoid if this is for a 71/72. #2 is for the air cleaner. The Hot Air choke is a metal line that goes to the choke coil spring housing.

One side of the hot air U pipe goes to the choke housing; the other side goes to the port on rear of the air horn so it pulls filtered air from under the air cleaner. There is a short section of rubber hose that connects the metal pipe to the nipple on the carb.
It is for a 72 application kinda its my 72 CS w a 70 455, and IIRC the carb is a 72 as well, but no TCS and no hot air choke, so i will block those two off.
