To do it right you need an exhaust gas analyzer.
Install the carburetor and try to get it to a point that it functions somewhat normally. This is where experience comes in and you can figure out what is about right for the engine, carb and altitude.
Run the engine at operating temperature and either on a dyno or out on the road. Watch the exhaust gas analyzer, if the engine is running too rich you'll need to install smaller jets/metering rods. If it's running too lean, go larger.
Once the jets are set up properly then you can adjust the idle mixture. The carburetor instructions should tell you the basics but in effect, turn the idle mix IN until the engine idle starts to load up, then turn it out to the point that it clears up. The book will tell you how far BEYOND that point to turn the idle mix screw. I usually go 1 to 1-1/2 turns beyond if I don't have a book in front of me.
On the carb on the back there is a needle and you will set that one to 15/16 and the one on the front of the carb you are going to set that one to 1 15/16 and then move it little at a time till it runs.
Use a dwell meter to set the gap at 30 degrees.
there is a screw on the carb right where the throttle cable hooks to it that you use to adjust the idle.
Sounds like you may have a clogged idle jet. Pull the carb off and clean your idle jet, blow through it to make sure it does not have any obstruction in it, then replace it in carb and try.
Check your timing and if it is a carb, check to make sure the air fuel mixture is set properly.
carb probably needs a rebuild, or mtering rods are set too rich.
Take the air cleaner off and you will see the carburetor bolted to the top center of the engine. That is what the air cleaner set's on. The top of the carb.
