Everything you wanted to know about automatic chokes but were afraid to ask pt5
I've noticed many people drive vehicles with inoperative chokes. Even though chokes can be intimidating, repairing and adjusting them actually is very simple.
So, stop pumping that accelerator and follow along as we look at how chokes work and how to repair them.
Rochester Quadrajet, the results!
Two mishaps, the first shown here, the choke coil I got was wound
backwards, it made the choke butterfly wind up TIGHTER as the engine warmed
up. I swapped on the one from the old carburetor fast enough, the second
mishap made me feel like a crud and what did I mess up later that evening.
The car would not start leaving the Etobicoke -Queensway show. It was not
getting gas. We got it running by priming the carburetor, and boy, was I
ticked at myself. In the end it was not my fault it looks like. The new
accelerator pump umbrella and rod was a very poor and frail design, the
umbrella came detached and stayed at the bottom of the of the pump well,
and was a distressed mess. The maker will get a note from me. The upshot?
The old assembly went in, all is perfectly fine, the slight tip-in
hesitation is gone now too. Stupid lack of pride it seems these days
making parts for even simple things like an old carburetor.
AMC Eagle Wagon 4x4 unifinished project
This is my 87 AMC Eagle Wagon 4x4. It runs but needs some adjusting of the
carburetor. I did a nutter bypass and installed a ford motorcraft 2100
carb, then stopped working on the car. The timing and carb needs adjusted.
Then my next step was to redo the Exhaust, and the interior. Then it would have
been good to go (maybe some touch up paint) it's for sale, also have an 85
eagle wagon that goes with it. Contact me if interested.
More Quadrajet tuning, some things! Part one in this saga on Sept 13, 2010
The car has a slight stumble and surge at a light throttle cruise at about
55 to 60 MPH. By swapping out the .050 metering rods to .048 units, the
stumble and driveability concerns are now gone. Going richer would mean
worse fuel mileage one may think? No! Now that the mixture is right, LESS
throttle opening is needed now, which means higher vacuum, and this way the
metering rods will block off the correct amount of fuel, and in the proper
timing and percentages, so the car runs much smoother. As stated many
times, patience and reading up on, and understanding how these intricate
carburetors work will help out very much! Enjoy!
Holley Carburetor Choke Adjustment Tips
How to adjust the electric choke on a Holley carburetor. A full explanation
of the components and operation of the Holley electronic choke and how to
properly adjust the choke's opening and closing times, as well as the

first tutorial ever take it easy on me. i didnt have the luxury of a vacuum
gauge around so i did a general way of tuning a carb by ear. If u want a
more perfect tune i suggest you use a vacuum gauge and or take it to a
