1969 Oldsmobile 442 Quadrajet Choke

I have an original numbers QuadraJet Carburetor for the equipment I have No. 7029251 on the original intake with the original choked. I know the choke spring has lost it's oomph and not allowing the choke to open fully. Is there an electronic replacement available for replacing this? Thanks, Al

There is an electric choke available if this is your question? Remove manual choke, install electric choke. We have a preferred protocol for wiring the electric choke if you decide this is what you want.

Why not replace it?

There's a few on ebay NOS, but they're pretty spendy. The Parts Place has a repro that may work for $79. No experience with it, but IMO, it beats trying to modify what you have.

The choke in that link only works for the 1970-newer carbs with integral choke. 1969 uses a divorced choke.

Isn't the "oomph" more to close the choke than open it? Is the crossover in the intake manifold getting hot?

Joe, I either forgot or I didn't realize 1970+ carbs. Thanks.

- Yes Joe is correct it is a divorced chock so the electric type suggested won't work. I guess my question would be is there an electric replacement for the divorced type used on a 69?
- Yes, I would love to replace it and I'm aware an aftermarket is available for $79 but my experience it would most likely be junk!
- Tru Blue if you have a good working original I'm interested.
- Sugar Bear thats an interesting question about the cross over, never actually checked it. When the manifold heats the coil will expand but it is 52 years old and I'm sure its lost its oomph! I'm going to remove the coil and bench test it.

Thanks for the responses

I found an original, but 1st you may check to see which hole in the choke flange you are using. Some work better than the others.
If you decide you need this one, PM me.

Contact Ken at Everyday Performance, www.everyday-performance.com. They sell electric choke conversion kits for divorced choke quadrajets. On the website there is none listed for the Oldsmobile QJ but the Pontiac kit looks like it should work. The Pontiac and Olds divorced choke QJ are almost identical on the choke side.
