FIGURE 22. MANUAL CHOKE SYSTEM.
(4) Automatic Choke System (figure 23). The automatic choke control
system is centered around a thermostatic coil spring. The spring exerts
pressure to hold the choke valve closed. Heat is applied to the coil after
the engine is started. The heat causes the coil to expand, allowing the
choke to open.
