TO INSTALL THIS DISTRIBUTOR. BECAUSE THE UNILITE
DISTRIBUTOR REQUIRES 7-16 VOLTS, A 12 VOLT ELECTRICAL SYSTEM IS ALSO REQUIRED.

GENERAL INFORMATION

Any coil or combination of coils with a total primary
resistance of at least 2.0 ohms can be used with this
distributor. We recommend a 2-3 ohm coil for racing
and a 3-4 ohm coil for street use. A coil with 4-5 ohms
resistance may be used. However, performance
may be reduced, even in street applications.
NOTE: Check the charging system and make sure
that it is producing no more than 16 volts.
We recommend a spark plug gap of .040" when using
a 2-3 ohm coil. A gap of .030" is recommended when
using a 3-4 ohm coil.
An optional spring kit (PN 29014) is available for this
distributor. The kit gives you a choice of 14 different
advance curve settings.

Step 1

Turn the ignition switch to the off position. With the
point distributor still in place and correctly timed,
rotate the engine until the points begin to open on
the front cylinder lobe. The front cylinder lobe is the
narrower of the two.
If the point distributor is not installed, rotate the engine
to the beginning of the compression stroke. Locate the
timing hole. Continue rotating the engine until the
advance mark is visible through the timing hole.

Step 2

Remove the ground cable from the battery. Remove
the point wire at the coil. Remove the point distributor.
