Idleing Issues!!!!

So, if it idles slow, set your timing first, then set your carb. No problem... That';s why all the adjustments are on it. You have seperate idle speed screws. the hot idle (slow) has the slotted end pointing straight forward. The cold idle (fast) has a screw that faces more down tha forward, and it's on the driver's side linkage. I find it easiest to shut the car off, open the throttle by hand, and adjust it a little, then fire the car up to make sure it's where I want. Also unplug the electric choke while you set the fast idle, or it will be trying to open every time you fire the car. Just make sure to plug it back on and let the thing warm up before resetting the slow idle. Once you have the speed(s) where you want them, use a vaccum gage to set the mixture for the highest smooth vaccum reading at your rpm. Also keep in mind that as youi adjust, the speed may increase or decrease. You have to adjust until it's all dialed in. Just for reference, I've been tinkering with my truck's carb a little here and there and it still needs some tweaking to be right after about 2-3 hrs of 20 minute adjustment periods.
