1.14.2.4.1. Cold Start Systems. The cold start systems (Figure 1-6) aids starting of the engine. All models, except
Model 350 PAFN use the manual system, while Model 350 PAFN uses the electrical system. In the mechanical system,
the operator uses the charge bottle to fill the reservoir. Then, prior to pushing the start button he uses the handpump to
inject starter fluid through the nozzle into the intake manifold. In the electrical system, a can of starting fluid is mounted on
the solenoid valve, which is controlled by the temperature switch mounted on the side of the engine. When the switch is
closed (it is closed at 40 degrees F and below) and the engine is started, the solenoid in the solenoid valve opens and
starting fluid is injected into the intake manifold through the tubing as long as the starter is energized.
