With the engine warm & running at wide open throttle (WOT), turn high speed mixture screw in until the engine begins to starve for fuel. Then turn the screw out until the engine begins to blubber. Now find the "sweet spot" in between the two settings. If you are working the engine (plowing, etc.), then the high speed screw needs to be turned out 1 turn or more beyond the "sweet spot" to be sure the engine isn"t starving for fuel and can develop its rated power.

The same procedure can be followed for idle mixture with the addition of the ldle stop screw to set the low speed RPM.
On the "M" carb, the idle mixture screw is an air adjusting screw so turning in will richen the mixture and out will lean the mixture.
Aren"t carbs fun!!
