Important fitment note

• This timer-base family was fitted to several V4 ignition configurations.
• Confirm the original part number, connector, wire count and mounting arrangement.
• Do not interchange it with the later 0583508 / 0763782 loop-charged Quick Start timer base.
• The flywheel, stator, power pack and timing linkage are included only when shown or stated.

🔌 Function

The trigger coils inside the timer base generate timed electrical pulses that identify crankshaft position.

The power pack uses those pulses to discharge the ignition coils. Rotation of the timer-base assembly advances or retards spark timing as the throttle linkage moves.

⚠️ Common Signs of Failure

• Loss of spark on one or more cylinders
• Intermittent misfire
• Spark fails when the engine becomes warm
• Backfiring or difficult starting
• Incorrect ignition timing
• Engine will not reach full advance
• Trigger resistance or output is outside specification
• Damaged wires or corroded connector terminals
• Timer-base bearing binds or has excessive movement

🛠️ Service Notes

Recommended checks before installation

• Match the wiring connector and wire colours
• Measure trigger resistance and peak output
• Inspect the timer-base bearing and retaining ring
• Confirm free spark-advance movement
• Check the power pack, stator and ignition coils
• Inspect the flywheel key and timer-base magnets
• Set maximum timing and throttle synchronisation to the correct engine specification
