Vintage Cars: carb, screw slot, stock carb

Question
Hi Don
Thanks for your help on the 64 Pontiac 230 Laurentian.
I was playing with the carb today.
It must be diffent than the one you were thinking of-this is a simple single barrel,no plastic parts or arrows,just a cub idle screw on the driver side and what I think is the choke screw on the other.
Nothing at all happens when I turn this screw-how do I know its working.
Thanks-I will be asking you more questions later if you dont mind!?

Answer
If there is a choke, it will be one of two types.  The manual type where there is a cable to the inside of the car, I assume this isn't it.

Or the bi-metal type with a round housing on the side of the carb, and some way to get heat to the metal spring, a metal tube, or a direct mount to the exhaust manifold.  There should be a black plastic cover, sometimes they were metal, over the housing with a flat screw slot in the middle.  There will be three little screws around the outside of the cover that hold it in place.  Loosen these screws a little and try turning the cover one way or the other.  One way makes the choke release sooner, the other way makes it release later.

If you don't have this, then I am not sure what you have.

Here is a site with lots of carb manuals:

Also, buy the service manual for your car, in this case, if you can't find the specific Canadian version, then buy a manual for any early 60's Chevy that covers the straight 6, since that is what you have.  E-bay should have them.

Of course this assumes you still have the stock carb, and I bet you do.
