im wondering what year my 40 is. The serial # is 022011. the motor has new coils,icieaned the points and set them at .020 but still no spark. The motor has its wiring harness and ignition,im turning the ignition with a screw driver the motor turns over but im wondering if this is why i have no spark,and if so how can i disable the wiring and just turn it over getting my spark from the magnito.
