🔌 Function

The timer base generates crankshaft-position signals and sends them to the power pack.

It also provides the timing information required by the Quick Start system and rotates with the spark-advance linkage as the throttle is opened.

Common signs of failure:

• No spark on one or more cylinders

• Intermittent spark loss

• Quick Start timing does not operate correctly

• Engine remains excessively advanced after warm-up

• S.L.O.W.-related ignition symptoms

• Misfire during acceleration

• Engine will not reach rated rpm

• Trigger resistance or output is outside specification

• Damaged wires or connector terminals

Recommended checks before installation:

• Confirm the 0583508 / 0763782 interchange

• Compare connector pin counts and wire colours

• Test trigger resistance and output

• Check the power pack and temperature-sensor circuits

• Inspect the timer-base bearing and linkage

• Set idle timing and maximum timing after installation
