I was on Epay and some guy wants $300 for a divorced choke for my 69 400
quadrajet. That's insane. So anyway I was hoping someone had one on here to sell me for about $10 bucks

Failing that, is there somewhere I can find highly detailed instructions on which electric choke conversion to buy and how exactly it is installed and adjusted. I will be using a 69 Rochester 4BBL on a 1973 smog 455?

 

Hopefully, someone has one for you.
Riggi'n a 73 would suck, won't look right either.
I think the 68-69 4 bbls all Olds BB are the same.

 

I have seen chokes that look very close to Olds chokes in OPGI.com.

 

$300? What condition?

I have a spare used one

NAPA sells an electric choke conversion for your Q-Jet. Easy install.

 

Are there differant one for differant engines? I have two that i come across in my boxes of stuff. I am not sure what they are from but if there is a number on them maybe someone could look them up?

 

According to the newly posted Master Parts catalog, generously provided by OLDSmobility (awesome dude!) the part number is 7036435 which describes it as Choke shaft and Lever kit. Not sure if that includes everything that is needed from the manifold up to the carb or not. According to the manual, this covers all 1969 4 BBL for every motor and transmission combination. According to Tru Blu 442 this would apply to a 68 as well.

Thanks dc2x4drvr, I'll check out the Napa conversion as well, in the meantime still looking for the divorced if very reasonalby priced. Thanks all!

 

I just saw this thread.

The first question we should be asking is, Are you using the original 1973 intake manifold, or the 1969 intake manifold?

You cannot use a divorced choke on a 1973 manifold - there is no place in the casting for the spring.

Similarly, you cannot use a hot air choke on a 1969 divorced-choke carburetor.

If you're planning on mixing and matching, your only choice is a manual choke (unless you mix and match the other way, using a '73 carb. on a '69 manifold, in which case you can go manual or electric).

Eric, Now I'm really confused

I thought you Had to use a 69 manifold

 

As seen in my thread on the subject:





Note the difference in the castings for the hot air choke tubes (gold small block manifold) and divorced choke spring (red big block manifold).

- Eric

 

Sorry Eric, I miss read the OQ

 

I think you mean "you cannot use a divorced choke on a 1973 manifold..."

 

Um. Yeah. Duh.

- Eric

 

I feel so much better now

 

Yes the 69 manifold, although the 73 manifold is currently on the car I will be switching it out unless there is some benefit to keeping the 73 on. I now gather from what you are saying, I cannot keep the 69 carb on the 73 manifold even with an electric choke conversion. Do I understand that correctly? If I keep the 73 manifold on I should looking for a different carburator. Thanks for your expertise.

 

Yeah, you've got it, unless you install a manual choke.

If you're installing the '69 manifold, then no problem, and it looks like some of the guys may have the parts you need, too.

- Eric

 

Buy or make a choke bloke off plate for the manifold and get an electric choke conversion kit. Joe Padavano posted a nice way to wire it up or go simple like I did and tie into to wiper feed (someday I'll fix it up right).

 

Those don't work with the '69 carb. he is using.

- Eric

 

Right, as configured originally

Now, one *can* convert the 68-9 carb to Hot Air choke and then convert that to Electric or Manual choke...

I have done this, and converted hot air '69 carbs back to divorced choke. It's a bit painful, because the choke linkage all the way to the choke shaft differs, and on one type the link does not come off the shaft, so you have to swap entire shaft/link or the entire air horn assembly. Painful, but possible.

Where were we?
The OP needs either a divorced choke coil and the intake to match, or a later carb that can be hot air or manual or electric - right?

I have the numbers that you can actually read on the part in my database

busy right now, please stand by...

It appears The Parts Place has just started to sell these chokes that are supposedly for a 68/69 4 BBL at what appears to be a more reasonable price.

Before I make the purchase can anyone verify this is the correct one? I can't verify from the schematics or part numbers I have.

Thanks,
Randy

 

Wouldn't it just really be easier and cheaper in the long run to get a 1973 carb?

 

Randy, Pretty sure that is the one.
The red one in the pic is from a 69 400.
The other is from a 66-67 to be used with
the shallow pocket manifold.

 

I agree. The red one in the picture, and the one in the previous picture, both look like the correct '69-'70 unit.

- Eric

 

Agreed

Taller unit with angled top part is 66-7

From the PN database [actual stamped-in number in bold type]

Group 3.750

The taller angled-top unit:

The above info is only as accurate as I can get from collecting off parts cars and looking up applications in the 1972 PN Manual. I had identical PN's for the first two, so that much at least needs to be corrected. The '094 PN comes from a recent epay ad 12/2013.

 

Just to clarify the post above,
The red unit is RP pn 35038.
And the 66-67 has RP pn 33762

 

You guys really are amazing with this stuff! I really appreciate the help on this. I can now go forward with this purchase confidently. Starfire I appreciate the idea as I may still do that if I can score one for cheap as it will be a while before I replace the intake manifold.

I now understand what is required in both the 69 and 73 carb/choke system.

Thanks all,
Randy

 

Check Ebay, they have 73 carbs from $9.95 to $250.00.

I've been dealing with this forever now as I have a '68 carb on my '67 330. I've been running a manual choke. I've got the '68 intake ready to go, just need time to install it. Tried to put a '67 carb on it, but the one I bought online from a supposedly reputable speed shop in Lansing won't run (idle mixture screws are frozen). So I need to either fix the carb or change out the intake. I think it will be easier to fix the carb.
