Distributor Spark VRDV
PURPOSE This valve is used with a thermal switch that connects the chamber halves (ports 2 and 3) after engine warm-up.
OPERATION When the engine is cold, this valve delays the
distributor retard during quick throttle openings.
When the engine is warm, the thermal vacuum switch allows the advance unit to respond directly to ported vacuum changes when the TVS bypasses the delay valve.
