Starter (Enricher) System
Pulling the starter (enricher) plunger causes fuel to be drawn into the starter circuit from the float chamber (1).
The starter jet (2) meters this fuel. The fuel then flows into the fuel pipe (3) and mixes with the air coming from the float
chamber (1). The mixture, rich in fuel, reaches the starter plunger (4) and mixes again with the air coming through a
passage extending from behind the diaphragm.
The two successive mixtures of the fuel with the air provide the proper air/fuel mixture for starting.
This occurs when the mixture is sprayed through the starter outlet port (5) into the main bore.
NOTE
A starter (enricher) system is operated almost the same way as a choke.
