I dont remember the last number on the carb, but I think it was 966. I cleaned it and put a Carb King kit in it. It seems to work fine, I just have never taken time to do a fine adjustment on it. I"m hoping that some of you can walk me through it, or point me to past posts that explain it. I searched this site but didn't find anything.

Set the idle speed close to your desired idle, then turn the mixture screw clockwise until you see the vacuum start to drop. Back the mixture screw out (CCW) until you get maximum vacuum, then go approximately 1/8 turn richer (CCW). Do a final adjust on idle speed without messing with the mixture any more.

People who get obsessive-compulsive about carburetor adjustment probably also lie awake at night wondering why the faucet in the kitchen sink isn't dripping!

I would first screw the idle adjustment screw in all the way (gently until it stops) and then back it out about 1/2 turn. Then I would start the engine, set the idle speed to 500 and then I would attach a vacuum gauge and turn the idle speed screw counter-clockwise (loosen it) until your vacuum is at the highest level but don't unscrew the idle screw more than 1/2 turn. You might think the engine runs better if your idle screw is more like 1.5 turns out, but you'll be running richer than you want at that point. Good luck!
