has gotten another JD wb mower 17 hp found the carb to be way out of adjustment fixed that but after mower runs and get hot it starts missing and then cuts off my thought is that could be a bad coil ?? or could it be that little ingniter on the side of the engine ? I thought that we they went bad it would'nt run at all ? has not done the ohm test yet on the coil just thought I would ask yous guys first ! and also when engaging the blades it kills the engine could it be the clutch adjusted up too much or just going bad ??
