You must have a loose wire, exposed wire or when assembled a wire has been crimped some how (metal to metal). As to the spark plug you might have some grass causing the the short as green grass wet grass will carry electricity.

Hope that this is of some help but without looking over the machine it is hard to give you a correct answer. cheers2
