My problem is not the CDI in principal, it is the = way MSD has=20 set the trigger signal conditioning, what I can not accommodate. =
The "Lethal" amounts of energy will start the engine = under=20 almost any condition.
We have grown up with " never turn a prop or trigger = a gun,=20 they may be loaded".
