i have a super a tractor,when i tried engagaging the pto it would not run i was thinking that the settings on the carb might be off cause i had a friend that said he new how to set the carb and after he got done it wouldn't even run so i truned the settings all the way in and backed the screw out about 1 1/2 turns and i set the air flow just where the gov was not pulling the rod back and forth i tried to keep it steady ?but when i put the pto in gear it still tries to die on me could it be my battery is not charged and it is keeping me from running right ? you can answer my question at mrauch1@roadrunner.com thanks mrauch1
