    My choke heat pipe broke. I could make a new one, or throw on one of the manual choke kits. Thoughts? Pros and cons?

    Now that I have my manual choke all hooked up and working well I'm sure I would prefer an Automatic choke. It's cool and all to have the knob and cable and look period correct but just more things to break and adjust.

    Funny, I feel the same way about automatic stuff.

    I like a manual choke but I grew up with the habit. And I enjoy the feeling that I'm more in a personal partnership with my vehicle. Enhancing the driving experience rather than diminishing it.

    On the other hand we could just make everything automatic, sleep while we drive, and call it a Tesla.

    One more thing you need to remember, if you aren't used to it.

    I like my manual chock on the 225 R2g....I was thinking of switching the quadrajet over to a manual choke as well - I am always wondering if the heat coil is working properly that opens the choke as it heats up (I am starting to get used to it).

    Is there a company that makes manual choke kits for different carbs ? or do I just cobble something together myself?
    I have a CJ5 with a 86 Cherokee V6 in it. Not sure what carb yet. Auto choke doesn't work because CJ doesn't have the electrical stuff for it.

    I wonder if a manual choke is another form of theft deterrence. If the thief can't start it, he can't drive it away.

    I'm not sure yet what I'll do for a choke when I get my CJ5 running, probably use what ever I have around that works.

    I much prefer a manual choke. I’ll go a step further and say I prefer a manual choke in conjunction with a manual throttle, as opposed to the choke ramping up the idle by itself.

    Every time I’ve tried an electric choke, it lasted about a week. It was never on when I wanted it, and it stayed on longer than it needed to.

    Manual choke on the '71 ren II because........... '69 converted to electric and love it.2-3 pumps and starts,fast idle,etc. only draw back with electric conversion is you have to have a 2GC to start with. Had a electric on the Renegade for a while and loved it but figured if i'm going to keep it stock that was cheating.

    If you want a manual choke, Dorman also sells kits to convert to a manual choke. IMO these are a bit clunky operating with the automatic choke fast idle cam, but they work ok. I have one on my J10 with a 2100 2V. The bracketing that comes with the kit is very flimsy, and I made a new bracket to hold the end of the cable using some hardware store bar stock.

    Wow lots of good info, thanks everyone.

    I do think the manual choke would go hand in hand with a manual throttle, sounds like a great setup. My only gripe with the automatic choke is not knowing if its open or closed-manual would fix that! I love manual stuff. Good point about the fast idle cam timgr, maybe I will stick with the auto because i dont wanna mess with too much to get it working smoothly. Thanks for mentioning that repair kit, I couldnt find anything like that and it should make for an easier time.

    I see there is actually vacuum going through the heat tube. Wouldnt that suck up dust and cause issues eventually?

    Yes, dust. The only filter in the original setup is the pipe sitting in the pocket of the exhaust manifold. The vacuum on the choke cover is very weak, and there is not much volume of air moved. Apparently AMC thought it was not a problem and carried it over directly from their automobile engines. The AMC Jeep engines essentially are identical to those used in their cars, AFAIK. The Dorman kit used to include a small wad of glass wool to go under the "stove" they supply. This was a filter of sorts. I don't see it in the current illustration of the kits, but you could add it.

    Re the fast idle, the automatic choke puts the fast idle cam under tension as the choke spring unwinds. This means that the fast idle stop, when under tension, comes off of the cam step when you open the throttle. The automatic choke also has very few fixed steps for fast idle that hold the idle up until you drive away. When converted to a manual choke with this kit, it seems to idle really fast, or you push the choke in and it's too lean. The choke part works fine, and there's no problem starting the engine, but you need to warm it up more than you might if you could finely adjust the choke and fast idle. The only factory manual choke I've looked at is on Holleys, and it does not have steps, but a ramp. So the fast idle is proportional to how much you close the choke plate. Nothing like this in a universal kit is available on the aftermarket, again AFAIK.

    I’m running a holley 470 TA carb that came with an automatic choke, the choke worked fine for the most part, but occasionally it would get stuck on the last part of the fast idle cam and no matter how much I adjusted it my idle was stuck at 1000 rpm.

    Also I felt the automatic choke would turn off too fast on really cold morning and my engine would be sputtering and leaning out. So I swapped to a manual choke and it’s much better imo. I get to adjust it exactly as needed and the engine starts on the first attempt every time, where if you left the key turned too long with an auto the choke would start opening.

    I also use the choke to bump my idle up when running my York OBA or winching.

    I was just in the process of converting my 2GC to electric when the thread started, good info. My electric choke conversion seems to move backwards. When it heats up it moves the choke shut. Did I get the wrong one? Part #8181A.

    Flip the coil over.

    I know I'm missing something but coil seems to be pressed in.

    It is a friction fit, usually. I know that you can flip the coil over in most cases.

    The cover for the Carter BBD turns the opposite way from the Holley/Motorcraft coil. The 2GC is a Rochester, no?

    I searched for 8181A choke cover, and did not find much. You could supply a link to what you bought.

    New cars are all automatic but I like my manual choke even if I cut it too early and the engine stops when I put on gas at a crossroad :shock::poo:.
    I use also the hand throttle when engine cold, particularly when I cross the local railway track.:bananatool:
    No barrier no signal only listening to the wind to estimate danger.:sick:
    The trick to put ones ear on the rail never worked for me. I am not John Wayne, and there is no train smoke.:Dcontrary to the sign showing an old train.

    This. Sometimes they're staked in a little bit and you'll need to do a bit of file work. Then get a couple of small screwdrivers and pry up on the center tang and it should pop out.
