my model# is 1059HG and ser.# is 15801. I try to start it and all it does is backfire so i thought the magnapower was out of it. I took the plugs out one by one and had spark to all of them. While i was checking wires for continuity, I got continuity between the pos. on the silinoid and the ground on the motor. I took the pos. clamp off the battery and tried it again and still get continuity for about 2 seconds then quits. I hope someone can help me.
