Reference

A-1677

Application

Distributor centrifugal governor

Features

  • Set of 2 springs for centrifugal governor
  • Suitable for 6V and 12V distributors
  • Controls ignition advance curve via centrifugal weights
  • Original specification for Auto-Lite distributors
  • Replacement when worn or spring tension lost

★ Correct specification for restoring the centrifugal governor in distributors with internal advance.

Application

For distributors with centrifugal governor on vehicles as listed in the product categories. Suitable for both 6V and 12V ignition systems.

Installation notes

The springs are fitted between the adjustable tabs on the carrier plate and the centrifugal weights. Spring tension and timing curve are determined by the position of these tabs – only adjust these with suitable test equipment. Check that the springs sit tightly between tabs and weights, not loose.

Compatibility

Fits various Auto-Lite distributor models (IGC-4705, IAD-4008, etc.) for L-134 and F-134 engines. Note: different distributor models have different timing curves due to varying spring configurations and tab positions, even though the same springs fit physically.

Historical context

The centrifugal governor was the standard ignition advance method in Auto-Lite distributors for WWII and post-war jeeps, where internal weights automatically adjust timing based on engine speed.
