While riding slow my bike stalls constantly. Just wondering if anyone has any ideas on how to fix or minimize the stalling. When I ride it real slow (like an uncleared rocky trail with a million trees) it will stall more often than not. Usually when I give it throttle, it will kind of cough and die. Would any carb settings change this? I'm new to four-strokes so I have not yet tried to mess with the fuel screw. Any help would be greatly appreciated!
