I have a Edelbrock performer intake manifold on my Buick 400cui 1967 are there any Divorced Choke Kit so I can have a choke on it?
Back in the day ,, there was a manual choke set up.... you could install one of those.... or possibly one of the ''hot water'' types like the 64 buicks had ,,,, or you could put a holley carb on with one of the electric chokes....:Brow::laugh: but the most reliable one is the manual set up.... aint pretty, but if you wrapped the cable in some electrical wire conduit, you can make it look better....just some ideas.....
This has been covered a bunch, You can use a GM part# 3989058 divorced choke stove and the correct cover that I can't find the number for and make your own linkage out of a suitably sized piece of wire to get an acceptable working choke. I too have the performer on my 455 with a QJ. I can post pics if you'd like?
On this board, You ask and you shall recieve :TU: Ok I found the part # on the cover too. These are old GM #'s and may not be available at the dealer any longer but a quick check on Ebay shows a couple of the thermostats available. I would try to find the cover as it acts as a travel limiter on really cold days. Without it the linkage can actually travel over center and the choke will never come off. Thermostat #3989058, Cover # 14006795 . I actually just went out in the garage and pulled mine off to take some better detailed pictures for you(and anyone else who would care to see). The linkage on mine is made out of welding rod since it's the correct diameter and bends somewhat easily although you can use just about anything 1/8th inch or smaller with good results. The bends were made with pliers and a vice to get a true or almost true 90 degree bend. The clip slot was made by gently using a pair of wire cutters to gradually cut the slot in the rod to the right depth for the clip then cleaned up with a file.
Thank you very much for you nice pics and your help. I have found this Edelbrock 1935 I wonder if I can modify it so it fit my Edelbrock 2146 intake manifold?
I see TA sells the choke coil and can but not the linkage. http://www.taperformance.com/proddetail.asp?prod=TA_1241
absolutely, That's the same coil and cover but you may still have to make your own linkage. The one in the picture does not look long enough but may be. You may get lucky and find it's just the right length but the L bend in the top of mine allows for a little adjustment.
There is nothing like old school ingenuity,you don't see much of this anymore. I can remember back in the day when there was all kinds of stuff like this in the car mags. Thanks for the tip David.:TU: Bob H.
Getting it adjusted right is the key. My heat crossovers are blocked in the head so it takes a while for it to completely come off but your climate may differ from mine here in North Florida. But compared to no choke? yes it works very well. There are a bunch and I mean a bunch of interrelated adjustments to the choke on our QuadraJets and if any of them are off it will affect the effectiveness of your choke. On mine I had to take the secondary lockout lever off my carb completely because even when completely warm and adjusted as close as I could get it to optimum the lockout would sometimes keep the secondaries from opening. The problem is caused by the fact that the original in intake thrnostat/coil has/had a longer operating throw or range then the on intake coil we have to use on these intakes. It takes some tinkering as we call it but it can work well and once it's corectly set you'll never have to mess with it again.
Ok I get the choke today and I have mount it, and it close the choke blade when cold, and open it at warm that is working. But I cant get it to aktivate and go with fast idle. I think I must adjust some things on the carborator?
There is a small cam, on the passenger side of the carburetor, that should rotate with the choke blade. The cam has several steps that raise the idle speed. There is a fast idle screw that contacts the steps. You'll have to look for it, as it is buried in there, and not easy to see. Make sure everything is rotating, and that the linkage isn't gummed up. There is an adjustment that may vary by year, for adjusting the fast idle screw. On my 70, it involves placing the adjustment screw on the lowest step of the cam, and adjusting the screw to produce an in gear idle of 620 RPM. When the cam rotates with the choke blade, and the screw contacts the high step of the cam, it usually produces a fast idle of approximately 1500 RPM.
