Richer is out for the load screw, richer is in for idle. Assuming you have a fuel problem you are too lean. It is possible to have both screws out of sync. Adjust the idle speed and mixture until smooth, with the throttle closed. With the engine at operating temperature and WOT, turn the load screw in until the engine runs rough then out until smooth, plus an additional 1/4-1/2 turn. You may have to adjust both more than once. If it is a fuel problem, and this does not correct it, your carb needs cleaning, or perhaps you have a fuel flow problem. The H/M engines warm up very slowly. I wouldn't use the term "pop", what mine does when cold is "stumble".
