Model 130202 Type 0135-01 ...It has no spark. I was all set to simply order an (coil/armature). When I stated to take it off I notice a wire running from the coil back into the motor housing? What is that? Of course there is the wire running up to the spark plug. And there is a ground wire with loop end that fits under one of the two bolts that mt. the armature. I would have to pull the flywheel to get to where this other wires goes to.
