Re: 1956 is 7.5 Johnson Mag

Randy,

if the ring is in fact in the correct orientation(flat up), ensure the brass ring on the ID of the mag plate is not cracked or broken. If the mag plate is fine, and the ring is correct, the slop can be tightened up by making 4 indentations with a flat screwdriver and hammer at the 3, 6, 9 and 12 o clock positions on the mag plate support ring (brass) Don’t hit it too hard, or will be too tight.

Are the four indentations made by hitting the bottom side of the brass mounting ring creating four small ‘speed bumps’ where the armature plate contacts the brass mounting ring? I recall seeing these on at least one of my motors.

I have been told that wear and tear can sometimes cause a loose armature plate, even with the mounting screws tightened down. The loose plate resulting in variable ignition timing and a motor that runs poorly.
