ok, 3 wires coming from engine. there is a small black wire that comes out of the coil. same as old motor. on the old motor this wire went to a square plastic mount on the plate for the throttle linkage, a wire from the dash also hooked to it with a stud in the plastic mount. the other 2 wires come out from under the flywheel, the smaller wire i know for sure went to the headlights on the mtd. the other is a larger red wire. the WH never had the headlights hooked up. yes i was sitting on the seat, i also started it with the brake in locked position. on the old motor there was only 1 wire coming from under the flywheel, it hooked to one side of some kind of electrical block on the cover, then a wire hooked to the other side of this block & goes under the dash. i do know that with the pto switch off , the pto runs when i start the motor.
ive sat out & studied this thing for a long time, here is what i thought of trying. i tought abought putting the old cover on it, hooking the red wire to that electrical block then the origanal wire to it like it was on the old motor??
