FORM 1479 (REV. A) 9/99

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.

INSTALLATION

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.

DISTRIBUTOR REQUIRES 7-16 VOLTS, A 12 VOLT ELECTRICAL SYSTEM IS ALSO

REQUIRED.
