1. Install the set screw into the intake manifold or
engine block.
2. Install the magneto into the engine. On Chevrolet
engines, position it so the hold down clamp
will align with the housing’s anti-rotation collar.
3. Install the billet clamp over the set screw and on to the
collar of the magneto. Put the flat washer, lock washer
and the nut onto the tud and tighten the assembly.
Timing Indicator
Note: On Chevrolet applications,it is recommended
to locate the wiring harness of the generator
towards the left side injector stack (Figure
1). This also puts the timing indicator of the
magneto in a position that should be easy
to view. Also position the band clamp’s
retaining screw so it points to the left and
is in the back of the magneto, close to the
firewall. On Ford and Chryslerengines, rotate
the base until the pointer is easy to view.

4. Locate which cap terminal is going to be the
number one cylinder. Mark on the housing
this location then remove the cap (Figure 2).
5. Loosen the band clamp and position thegenerator so
the rotor tip is just leading into the number one cylinder
mark (from step4) indicating the number one cylinder
(Figure 3). This will put the timing approximately
2°-3° within TDC or where you have the timing
set. Note: Always verify timingwith a timing light.
