Cold Start Injector: Description and Operation
Cold Start/Running Controls
COLD START/RUNNING CONTROLS
A cold start valve sprays additional fuel directly into the intake manifold when a cold engine is being started.
The thermo-time switch controls the cold start valve so that the engine will not flood if it does not start immediately.
The control pressure regulator acts like a "choke", to enrich the fuel mixture while the engine is warming up.
The auxiliary air regulator acts like a "fast idle cam" to slightly increase idle speed while the engine is warming up.
