A quick and easy thing to do is hook a vacum gauge to the carb at one of it's ports and then adjust your idle to your normal idle rpm, then begin turning the 4 corner idle screws in/out, 1/4 turn at a time, till you get the highest vacum reading, all the while re-adjusting your idle rpm to your normal idle rpm,you'll have to do this a few times to get it, but,it's a start, then road test.....
Another thing, do this with the engine fully warmed up at operating temp.......
Carbs are not hard to tune, just takes a little time.......
