I agree , with these little motors it seems temp,humidity ect. affect it alot more . Does the motor "clean out ? Or does it rev up and then begin to bog down at high revs ? Have you checked the plug ? Are you always running at the stock setting on the carb ? (3 turns out) if so I have found that to be way too rich , try leaning it out 1/8 to 1/4 turn and see if that helps .
