Section 7. [. . . ] Installing Pawls and Pawl Springs. 7. 4 Section 7 Retractable Starter 4. Place the brake washer in the recess in starter pulley; over the center shaft. Lubricate the brake spring sparingly with grease. Make sure the threads in the center shaft remain clean, dry, and free of grease and oil. Apply a small amount of Loctite® No. Install the center screw with the washer and retainer to the center shaft. Torque the screw to 7. 4-8. 5 N·m (65-75 in. Tension the spring and install the rope and handle as instructed in steps 6 through 12 under "Rope Replacement" on page 7. 2. Install the starter to the engine blower housing as instructed in "To Install Starter" on page 7. 1. 7 7. 5 Section 7 Retractable Starter 7. 6 Section 8 Electrical System and Components Section 8 Electrical System and Components This section covers the operation, service, and repair of the electrical system components. Systems and components covered in this section are: · · · · Spark Plugs Battery and Charging System Electronic Ignition Systems (CD and DSAI) Electric Starter NOTE: Do not clean spark plug in a machine using abrasive grit. Some grit could remain in the spark plug and enter the engine causing extensive wear and damage. As soon as the original pulse drops back to zero, the capacitor in the delay circuit begins to charge. When the charge on the delay capacitor exceeds the charge on the charge pump capacitor the comparator changes state, activating the pulse generator. This pulse turns "ON" the CD ignition module semiconductor. Energy is then transferred to the secondary of the output transformer (T1, Figure 8-5). The high voltage pulse generated here is delivered to the spark plug, causing arcing of the spark gap and igniting the fuel-air mixture in the combustion chamber. As the trigger pulse is generated, all associated circuits are reset, their capacitors discharged. The longer it takes the delay circuit to surpass the charge pump capacitor voltage, the later the trigger pulse will occur, retarding the timing accordingly. Troubleshooting CD Ignition Systems The CD ignition systems are designed to be trouble free for the life of the engine. Other than periodically checking/replacing the spark plugs, no maintenance or timing adjustments are necessary or possible. Mechanical systems do occasionally fail or break down however, so the following troubleshooting information is provided to help you get to the root of a reported problem. The CD ignition systems produce a high-energy electric spark, but the spark must be discharged, or damage to the system can result.
