Post subject:  Update on supersix conversion w/electric choke
Well, finally got a remanufactured carter bbd for my 225.
Hopefully this ones not "junk" like some people think they are. This one at least seems to have a nice tight throttle shaft, no play at all.
Its on the car and running great ! Also because of the year of exhaust manifold I had, the choke stove was open to the inside of the manifold. So I couldn't just bolt on a later type choke coil. So I decided to adapt an electric choke setup to my bbd !
I was poking around on ebay, and found that the Jeep bbd's from around 84 and up, had an electric choke.
I bought one of these carbs off ebay for $10 bucks took the choke assembly off, and adapted it to my slant6 bbd with a carefully made adapter plate. So, its up and running and the electric choke works great, and I've made a block of plate for the old choke stove hole in the manifold.
Heres a couple of pics !
first is the block off plate for the choke stove

Next is a pic of the adapted choke assembly on the bbd

Last is a pic of it completed and running !

Next i'm thinking of some kind of custom built air cleaner assembly. The old 1bbl air cleaner wont fit,, the supersix air cleaner is HUGE and ugly. So custom must be the way to go ! I'll post some pics of that project as well as soon decide on a design.
Any ideas or suggestions ??

Good work! Now you just need to start a production run of those "carefully made" adapter plates for the Jeep electric choke for those of us who are "fabrication-challenged"! You've got at least one sale already — just tell me where to send the check... !

That's nice work, and I'm interested to see that it's working great. I can't get a BBS to run right on my Valiant (warm up) due to the choke opening rate being too quick, that may be a viable alternative. Why the teflon tape on the inverted flare fuel line fitting, tough? Only pipe threads should require sealant or tape.

Say, that's a nice, clean setup! How well is it working for you, have you hooked it up yet?

I had something similar to this, but on a Chrysler Export BBD that originally had the heat tube type choke built right into the air horn (Carter called this "Carter Climatic Choke Control"). I removed the CCCC housing and installed an electric housing very similar to the round black part of your setup. It worked fine once I got it dialled in, but you really want to put a modulator in to control the power to this kind of choke. Just hooking ignition-on 12v to it won't work; it'll make the choke start to heat up and come off as soon as you turn the key to "run". Generally the car will start up just fine (unless you leave the key in "run" before you start it!), but the choke will tend to come off way too fast and leave you gasping and stalling before the engine's fully warm.

I sold the car before I had the chance to do a lot of playing with different modulators. You could use a Chrysler modulator, NAPA Echlin 2-1695
or you could use one of the universal modulators that's frequently sold with electric choke conversion kits. It's the square box that comes with NAPA Echlin 2-1679.

These devices monitor the ambient temperature and control the voltage to the choke heater to match.

Thanks, Dan, this is good stuff.

Y'know, DW, you just reminded me that I was on the phone to one of the carb supply places a few months ago and happened to ask about an electric choke conversion for 1bbl slant-6s, and he said "Yes". Now I just have to find my notes from the conversation, give me a few days. I did buy such a kit from JC Witless about 15 years ago -- in fact, that's what I robbed the electrically-heated coil and housing from for my abovementioned BBD rework. JCW no longer lists those kits, but I still have a few trick sources to try, so stay tuned.

...was it Willy Carter or Buddy Holley you were on the phone with? :wink: :lol:

OK, well just so you guys know.
I've only had this setup working for a couple of days now. I tested the choke twice from a cold start, but in the garage where its not all that cold. I did notice that the choke did seem to pull off rather quickly, so i'm not sure how it will do on a cold day.
Its possible that I do need one of those voltage modulators on it so it pulls off more slowly.
I'll try picking one of those up and putting it on this weekend and see what kind of difference it makes.

The teflon tape around the fuel inlet fitting was just a brain fart.
It was on there when the one barrel was on the car, so I just redid it on the two barrel. But your right, it shouldn't need it.

p.s. Thanks for those p/n's dan !

Teflon tape on the inlet fitting is a tremendously good idea. Prevents this junction from freezing/seizing and rounding off the next time you loosen it!

Glad to help with the P/Ns.

DW, I just took the computer in for service this AM that has the bookmark to the page I *think* those kits were on; I can't find 'em right now with a google search. Bear with me. The setup was pretty nifty; it had the round black choke coil housing mounted to a bracket that bolted to the exhaust manifold in the stock choke location. A pushrod exited the side of the bracket and went up to the carb from there. But since we're on the topic: Do you still have the choke thermostat you remove with the Holley? SLap it back on and see what happens!

Did anyone ever come up with a source for a choke conversion kit for a Carter BBD?

That looks great. I love the look of your valve cover... is that black chrome?

Don't start getting all drooly over the valve cover just yet, it's one of the ones discussed Here and Here.

The reason I ask is that I have a stock cover and I'm trying to decide what to do with it. The easy thing would be to just paint it or I could have it powder coated. I was kind of leaning toward having it chromed plated but when I saw the one above I got to thinking about black chrome as a alternative. It costs more but on the other hand it would be something relatively unique and, I think, very classy looking.

I already knew about the Chinese covers and whatever temptation I had to give them a try was quickly gone when I discovered that they are unbaffled.

Whatever you do to it will look good if a quality job is done of it. Stock engine color, black-crackle paint, red-crackle paint, chrome...I had one powdercoated some years ago; wouldn't do it again. More hassle and expense than it was worth, adn the end result didn't come out as nicely as one that I painted after VERY careful prep.

The stock covers look really nice chromed.
