Like others said, check the compression, check for a good blue spark at each plug, not just at the distributor. Each plug wire should deliver a 1/4" blue spark to ground. Be sure the centrifugal advance in the distributor is free and will spring back when released. Check for vacuum leaks.
Save the carb adjust for last.
The engine needs to be properly tuned and healthy to get a good adjustment.
Make sure the air cleaner is clear and clean. There is a wire mesh inside the canister that is often neglected. If packed with dirt it may have to come apart, but try soaking in solvent and blowing first. Be sure there are no mud dobber or mouse nests in the pipe. Get it up to operating temperature, set the idle speed down to 400-500 RPM.
The idle mixture screw is the small screw with a spring up by the mount flange. Unlike modern carbs, the screw regulates air, not fuel. Turning it out leans the mix, in richens it. Back it out until the engine stumbles, then back in to best idle. If it makes no difference, the idle speed is too fast or the idle circuit is clogged.
The high speed is the large screw on top of the bowl cover. It's a little tricky to adjust. Turn it in about a turn, then open the throttle as fast as possible. Listen to the response. If it hesitates, back the screw out about 1/4 turn. Keep repeating the test, adjusting the screw until the engine will take sudden throttle without hesitating. A single puff of black smoke is desirable.
