Qjet Choke problem

I am having QJ problems with my 85 Chevy truck with a 305. I've been through several posts and cannot find this exact problem. I have three Qjet carburetors. One is a computer controlled carburetor. The other two are regular Qjets without electric choke. I would like to use one of these carburetors on my truck now. I've recently changed over to a performer intake and non-computer HEI. I know I can't use one of them because it's the computer controlled one. One of the other two is missing some choke parts. The third one is missing the little spring thing that goes on the intake manifold. I do have the spring off of a two barrel manifold and the choke rod. Will these work? If not, can I make the carburetors manual choke just using a choke cable to open up the choke from inside the truck? If I remove the choke mechanisms from the sides of the carburetors, will they work? If this is not feasible, I have a 750 Holley DP that I know is too big, but can I jet it down with 600 Holley DP jets? I absolutely cannot make the 600 double pumper work right. That's what is on the truck now. Sorry for the long post. Thanks in advance for your help.

If one's just missing the linkage rod that goes between the coil on the manifold & the choke linkage, you could probably make one from a piece of welding rod. Mine just needed a couple of 90* bends toward the carb. You may have to experiment with length, but welding rod's cheap. If you need the coil itself, just hit up the local junkyard.

Choke conversion

You can use the thermal spring and rod if your manifold and carb line up for it, but is the interior of the intake manifold setup for the choke setup to warm up the thermal spring on startup? I would Use one of the non computerized carbs. Two different way of doing this, #1 there is an electric conversion available for almost every non electric carb choke assembly out there, remove the choke cover and install the new cover, set up cover and route electrical wiring, 2nd is the hand choke conversion. Simple package to hookup, remove old cover, setup choke lever with cover, install, route cable, done. elect unit = avg. $60
handchoke = avg $10
If you want the electric unit, call the parts store with your number off the carb and tell them you want the electric choke conversion, Napa and Borg Warner have them.
hope this helps, broken wire
