probly CDI connecting to system. Bee glad the overheat sensor buzzer works on the
ol' girl. Its ALWAYS a good idea to go over the wireing harness for a broken wire or
dirty connection, and dielectric grease everything at all points, includeing fuses-holders. WD-40 ignition wires & componets. Marine grease fittings, intakes (both)
water & carb. Is it not sparking or not spinning over to even check that?
