SUPER-MAG ® IV SPRINTMAG ® III
INSTALLATION PROCEDURE FOR SINGLE AND DUAL IGNITION SYSTEMS
Step 1
Rotate the engine to top dead center (TDC), #1 cylinder on
compression stroke. Remove the magneto cap. Position the
magneto in the engine with the rotor pointed toward the
desired #1 plug wire position. CAUTION: BE SURE THE
MAGNETO IS FULLY SEATED. Set the distributor hold
down clamp in place but do not tighten at this time.
SPRINTMAG ® , SPRINTMAG ® II and SPRINTMAG ® III:
Be sure the magneto pointer aligns with (zero) on the timing
plate on the generator. Also, be sure the band clamp is tight.
SUPER-MAG ® II, III, AND IV, LEFT-HAND ROTATION:
Be sure the magneto pointer aligns with the left side edge
of the timing plate on the generator. Also, be sure the band
clamp is tight.
SUPER-MAG ® II, III, AND IV, RIGHT-HAND ROTATION:
Be sure the magneto pointer aligns with the right-side edge
of the timing plate on the generator. Also, be sure the band
clamp is tight.
Step 2
Static Timing (TDC Method)
Connect the static timer (buzz box) to the generator (see
Figures 1 and 2). Turn static timer ON. If the buzzer begins
sounding, turn the magneto in either direction until the
buzzer is silent.
LEFT-HAND ROTATION: While the buzzer is silent, hold the
rotor clockwise and slowly turn the magneto counterclockwise.
Stop turning the magneto when the buzzer begins sounding.
Tighten the distributor hold-down clamp.
RIGHT-HAND ROTATION: While the buzzer is silent, hold
the rotor counterclockwise and slowly turn the magneto
clockwise. Stop turning the magneto when the buzzer
begins sounding. Tighten the distributor hold-down clamp.

Step 3
Make a mark on the generator below the rotor. Install the
magneto cap. The post on the magneto cap over the mark
made on the generator is # 1 cylinder. Install the spark plug
wires in the sequence of the firing order.
Step 4
SET TIMING. Loosen the band clamp.
SPRINTMAG ® AND SPRINTMAG ® II: Turn the generator
to align the pointer and timing plate to the desired initial
timing. Tighten the band clamp.
SPRINTMAG ® III: Rotate crank hub to align with timing
mark and pointer. Use static timing method to set timing.
Recheck timing with timing light above 3500 RPM. By
leaving the pointer on "0", the timing may be reset without
the use of a timing light. To reset timing, loosen the band
clamp and rotate the generator housing.
SUPER-MAG ® II, III, IV: Turn the generator to align the
pointer and timing plate to the desired initial timing. Each
mark on the timing plate is 2 degrees. Tighten the band clamp.
NOTE: Timing may be checked with most timing lights
after installation is completed.
Step 5
WIRING PROCEDURE
Connect long harness to the generator. Refer to WIRING
DIAGRAMS on pages 2 and 3 for all additional wiring.
