limiter and selecting an advance curve.
COIL(S)
A coil(s) with a total primary resistance of 2 to 4

INSTALLATION
Step 1
Turn the ignition switch to the off position.
Rotate the engine until it is on the compression
stroke for the front cylinder. Continue to rotate
the engine until the TDC mark is visible through
the timing hole. (see repair manual if necessary).
Step 2
Remove the existing distributor if still in the
engine.
Step 3
Remove the two button head screws from the
top of the Mallory distributor. Pull the top cover
off the distributor. Remove the two hex standoffs
and pull the module and upper housing off the
distributor base assembly. Adjust the switches
on the module for the desired advance curve
and rev limit.
Step 4
Install the distributor base assembly in the
engine with the screw holes and shutter wheel
positioned as shown in Figures 1 and 2. It may
be necessary to pull the distributor out, turn the
shaft and reinstall to get the shutter wheel at the
approximate angle shown. The slots should be
at about the11 o’clock and 7 o’clock positions.
The screw holes should be at the 9 o’clock and
3 o’clock positions.

Step 5
Install the distributor clamp and tighten the
clamp bolt lightly so the distributor can still be
rotated.
Step 6
Set the upper housing on the base assembly as
shown in figure 3. (The upper housing will only
install one way because of the locating screw)
Rotate the base assembly slightly if necessary
so that the slot in the shutter wheel lines up with
the slot in the upper housing. Tighten the
distributor clamp.
