Recently found out that if you have a MSD ignition system you should not use a degree'd timing light. As per MSD you get false readings. The impulses sent by the box vs they circuitry in the light give you false readings. MSD says you should use a plain Jane timing light with a degree'd balancer or a timing tape. Just FYI.
