Ignition Timing: Adjustments

Timing Hook-up:





1. Clamp timing light inductive pick-up on orange lead (beside fuel filter).

2. Start engine and check timing at flywheel access.

NOTE: Timing is not adjustable. If timing is not within specifications (behaves erratically), control unit or wiring may be at fault.
