2. Remove condenser lead and primary lead
from nylon insulated connection.
3. Loosen two screws that hold base of contact
set assembly in place, and remove contact points.
4. Inspect condition of advance weights. If nec-
essary, add a small amount of cam and bearing
lubricant to the advance weights.
c. Installation
1. Position replacement points under the two
screws and tighten screws.
2. Install condenser lead, primary lead and
secure with retaining screw, Fig. 12-18.
NOTE: Leads must be properly positioned to
eliminate interference between cap, weight base,
and breaker advance plate.
3. Install rotor cap and secure with two attach-
ing screws. Square and round lugs on the bottom
of the rotor must be aligned with corresponding
holes found on cam weight base.
4. Position distributor shaft so that contact arm
rubbing block rests on one lobe of distributor cam.
5. Insert 1/8 inch Allen wrench into head of the
adjusting screw and turn clockwise until points
close. Then turn screw counterclockwise 1/2 turn.
6. Replace distributor cap.
7. Adjust contact points as outlined in step d.

Engine Running
Preferred Method:
1. Connect a dwell meter to distributor primary
lead.
2. Lift adjustment window and insert Allen
wrench into head of adjusting screw.
3. Turn adjusting screw until 30° dwell angle
is obtained as measured by dwell meter.
4. Last adjustment should be made by turning
clockwise, in order to maintain a more uniform
gap.
NOTE: It is unnecessary to check point gap,
because of close manufacturing tolerances. The
gap will be correct if the dwell angle is 30°.
Alternate Method:
1. Lift adjustment window and insert Allen
wrench into head of adjusting screw, Fig. 12-19.
2. Turn adjusting screw in (clockwise) until
engine begins to misfire.
3. Turn wrench 3/4 turn (270°) in opposite di-
rection (counterclockwise), and then turn clock-
wise 1/4 turn (90°) to obtain proper gap and dwell.
The correct cam or dwell angle setting of the
distributor is 28° to 32°.
