IGNITION SYSTEM
At slower speeds, the flywheel magnet induces a
smaller charge in the trigger coil. This action triggers
the silicon controlled rectifier (SCR) enabling easier
starting in a “retarded firing position” about 5 degrees
before top dead center (BTDC). (See Figure 50.)
CD Pack Air Gap Adjustment
1.
Rotate the flywheel until the magnets are directly
adjacent to the CD Pack as shown. (See Figure
52.)

2.
Adjust gap by loosening screws, inserting Lawn-
Boy gauge (P/N 604659) or a piece of .010" (.25
mm) shim stock and tightening screws. Remove
the shim stock or gauge.

At faster speeds (about 800 RPM), the flywheel
magnets induce a large enough charge in the trigger
coil to trigger the SCR in the “advanced firing position”
(about 28 degrees BTDC). (See Figure 51.)
CD Pack Removal/Installation
1.
2.
Disconnect leads and remove mounting screws.
Replace CD Pack, and set gap as outlined in step
1
above. Tighten screws. See specifications for
torque values. (See Figure 53.)
