i know this topic should be in the engines section of the forum, however, i since i own a '78 CJ7 i am interested in other CJ owners opinions ...
i am rebuilding my AMC 304 V-8. currently it has motorcraft 2150 2 bbl carb with a mechanical choke. the choke is a hard tube that goes into a "choke stove" in the intake manifold. the hard tube is rusted through (no surprise there). i am set on getting a rebuilt 2150/2100 but am debating on going electric choke or manual.
i like the thought of a simple choke cable routed to the dash. on-off... old school; and i know it will always work.
My experience in the matter is on a Holley carb, not the Motorcraft you're looking at, so it might not be quite the same. That having been said, I definitely prefer my manual choke setup- I had an electric choke which I removed and installed the manual choke. It's simpler, and I've just had better luck with it. My cable is set up like you're talking about, with the cable routed through the dash, and so far I like it.
I have a properly adjusted and functioning electric choke on my 304 and I have never had an issue with it in cold or hot weather. The key is to ensure it is properly adjusted for spring tension and throttle plate clearance, and that the electrics are properly hooked up. After that, it is a "install and forget" item....
me too i got my choke adjusted i live in michigan and even on the coldest days before school it alwase starts(even though some mornings i wish it wouldnt) but once i got it adjusted it has never gave me a problem

I will always run an electric one over a manual choke because it is one of those things you never have to think about. Once you rebuild your carb and set the choke while installing and adjusting the carb, you never will touch the electric choke again.
I don't feel like working on anything, at this time.
What he is referring to is using the cable that is usually mounted in or under the dash. The other end is attached to the carb linkage. On board air in this case would run off a engine pulley, think AC compressor. The more RPM's, the faster the air pumps up.
The problem with a choke cable to increase RPM, is that there isn't enough resistance with the cable to overcome the spring on the carb.
Most people use a shifter cable and thumb control from a bicycle , the shift cable can be tightened at the thumb control, to overcome the spring.
