1950 super 6 carb
-
My son has a 50 super 6 sedan. we have a question on the choke cap number that fits this car.My parts book is unavaliabe. Is this cap all by its self or are there other caps that will make the choke work properly. The cap we have on it now closes the choke when the car is hot and makes it flood out when starting. We have adjusted and adjusted with no solution.We know the cap is not the right one.Thanks for any help you can give us.

HI, if your carb number is 776s I might be able to help.
You can e mail me at tunentime@hotmail.com if you like.

Just a guess, but could you have the spring inside the cap turned the wrong way?

Roy I cant seem to e-mail you. My computor wont except your e-mail. Anyway ,thanks for the help you two. The problem is the car is 500 miles from me so it will take awhile for me to get the info. We have always had trouble with the choke closing to fast when the motor is hot or warm and flooding. I have many choke caps but this one is smaller in diameter. It is the original cap and the windings in it are ok. I will work it out but thought I would ask if anyone had had this problem. Thanks again.

I'm no expert on automatic chokes, but wouldn't the problem lie in the thermostatic spring (or elsewhere) rather than the cap?
One turns the cap to lessen or increase the thermostatic spring tension, so that the spring "relaxes" at just the right temperature, thus opening the choke. Right? All the plastic cap does is to grab one end of the spring (the outer one?) and twirl it one way or the other. Possibly what you are saying, is that the ''grabber'' on the inside of the cap, is not properly engaging the outer end of the thermostatic spring. In that case, you can turn and turn until the cows come home, and the spring won't do anything.
Maybe the spring itself is at fault. Ever try substituting another (used or new) one from a different Hudson (or even another make)?
Another potential problem would be the little tube that runs to the manifold choke stove, and through which hot air is drawn by vacuum into the thermostatic control (where it affects the spring). Is the tube clear and open? Is it correctly attached to both the thermostatic control, and the manifold choke stove? No big leaks?
These little automatic choke gizmoes are pretty darned bulletproof. The one on my '37 works like a charm. I'm sorry your son has this problem but I think it's gonna be something with a fairly easy solution.
