I just had a problem like that with my MSD. Tried 3 timing lights,even hooked up power to the light from a seperate battery from the car--still bounced up and down 3 or 4 degrees.Come to find out the nut on the pin that goes thru the hole used to lock out the timing, had loosened.A washer, a drop of loctite and reinstalled the nut -timing was again rock solid.The hole did oblong slightly, but so far it has stayed very steady.
