Quoted from megoman:My plate is pulling too far back when the coil fires and this is dislodging the pawl.
Does the coil in the unit match the coil specified on the schematic? It may have been replaced at some point with a slightly shorter coil.
Could the pawl be worn so that it's a little shorter than it should be?
Should there be, or could you add a spacer or washer between the coil base and the frame to push it a little closer to the armature?
