H Carb Adjustment

Thanks to everyone on this website my H is running pretty darn good. I have tweeked the carb fuel adjustment screw on the bottom of the carb but I'm not sure I have found the "sweet spot" just yet because I haven't adjusted it under a load. What will happen if I screw it out too far? This spring I'll be pulling a 2-14 plow so that's the time to do it. How much play to I have from "in and out" with the screw? 1/4 turn, half turn? What is the margin of error to get the right sweet spot?

Factory initial setting is three turns off the seat. Your H will pull that 2-14s just fine at that setting.
