Install lower half of vibrator first. Carefully bend mounting bridge by tapping with a hammer and nail set or punch at "B" or "C" to obtain 1/ 16" gap at "A". Hold punch at "B" to reduce gap, and at "C" to increase it.
Apply upper bridge, and adjust nuts "G" to obtain 1/32" gap at "D". When in this position, there must be some clearance between upper vibrator leaf and rivet head at "E". If there is no clearance at rivet head, tap upper bridge lightly with the punch at "F" until clearance is obtained. Then rest gap at "D" to 1/32". Be sure points match and seat together evenly.
Tighten all electrical connections, then connect Fairmont F7838 low reading ammeter in primary circuit and, if necessary, make further adjustment for .85 to .95 amperes current draw. This should be done by again tapping lower bridge at "B" or "C". Do not change the 1/32" gap on "D". Tighten lock nuts at "G".
Check and clean spark plug regularly, and maintain 1/32"
gap at points.
