Ignition Electrode Adjustment and Cleaning:

The Ignition Module produces a high-voltage spark across the
Ignition Electrodes; therefore, the Ignition Electrodes must be
properly adjusted and maintained to ensure that the fuel mix-
ture is ignited when appropriate.
Adjusting the Ignition Electrodes:
Using the Beckett T-Gauge, verify that the Ignition Electrodes
are properly adjusted as in Figure 64. If the Ignition Electrodes
are not properly adjusted, perform the following procedure:
1. Slightly loosen the Electrode Clamp retaining screw with a
3/8 inch socket wrench.
2. Referencing Figures 63 and 64, properly align the Ignition
Electrodes.

the metal tips of the Ignition Electrodes, with a Scotch Brite

Ignition Electrodes are properly adjusted with the
