The magneto creates energy & does not go away. Needs to be discharged before it finds the easiest path thru ground….thru the windings & mag plate. It WILL blow tiny holes thru the coil to ground opening secondary windings causing an open or carbon connection.
Also when checking compression I would say around 20% difference between cylinders is out of spec & needs attention.
