Carter AFB carb - The 1947 - Present Chevrolet & GMC Truck Message Board Network

neonlarry · 09-04-2002, 11:07 PM

I am thinking about buying a 600cfm carter afb carburetor (I know it's the same as the edelbrock, but I like how the carter looks). I was wondering if it would be better to get the electric choke one (that has the egr hook up and stuff) or get the manual chocke one and convert it to electric. I will be putting it on my 350, that (when I out the carb on) will have a weiand intake, stock HEI rebuilt with pertronix parts, and a set of hooker headers as soon as I have some more money. (I may be putting a rebuilt 350 engine in soon too, but it would use all of the same parts except I will get a comp cams high energy 268h cam too).

Just buy it with the Electric Choke and find a wire that is powered when the Key is on and hook up the electric choke on that wire and be done! My 68 has a Carter AFB w/ Electric Choke and it works fine!

i believe the carter and edelbrock share this..the electric choke models a set up more for gas milage and the manual choke is set up more for performance....nothing a little rejetting either way will fix.. just an observation

I have both. Carter on 68 and Edelbrock on 67. I like the Carter much better.

I have a 600 Carter AFB with electric choke on my 72 truck. I love it. TJ

It really does't matter. It will run ok out of the box, but if you want it dead nuts right you will have to calibrate it for your engine combo. I would buy the one with electric choke. Carter and Edelbrock are the exact same carbs, they are both made by weber.

I recently bought a Holley model 4150 4 barrel barb for my
69 C10 P/U. This version had the electric choke. I searched around on the fuse panel for ignition-on 12v. Ran the wire
to the carb and hooked it up. Fine. So now when I start the
engine the choke forces the RPM up to 1500-2000 for x number
of minutes until the thermocouple in the choke allows the
carb to drop down to its normal idle of 700 RPM. It does this
irregardless of the outside air temp. Whether it 25 degrees
or 95 degrees you have to sit there and wait for the choke to
"catch up". Am I doing something wrong? Is this the way all
electric chokes work? I thought that the choke only came into
play in cold weather?

I don't have any experince with Holley carbs, but that is not the case with the Carter AFB electric choke. The electric choke is fully adjustable by rotating the black plastic housing on the side of the carburator. The instructions are pretty good at explaining how to adjust it.
I wouldn't be suprized if the Holley wasn't the same way. It doesn't seem right for it to go into the high idle mode when the engine is already warm. Maybe somebody on the board knows the answer. TJ
