Step 10: Adjust Ignition Electrodes
1. Using a 10mm socket, slightly loosen the retaining clamp bolt.
2. Place the electrode adjustment gauge on the nozzle manifold hex and insert the metal tips of the ignition electrodes into
the appropriate notches of the electrode adjustment gauge.
3. Using a 10mm socket, tighten the retaining clamp bolt.
4. Remove the electrode adjustment gauge.
NOTE:
Be sure not to over-tighten the retaining clamp bolt when readjusting the ignition electrodes. Over-
tightening the retaining clamp bolt will bend the retaining clamp and prevent the photo disc from floating
freely. Not allowing the photo disc to float freely will cause poor combustion, and result in a smoky exhaust.
A bent retaining clamp can be re-straightened with a punch and a hammer. Lay the clamp’s beveled side
down on a solid flat surface and align the thick end of the punch at dead center. Tap the punch lightly until
the retaining clamp returns to proper form.
