5.4 Section 5 Fuel System and Governor Slow Circuit: (Figure 5-2) At low speeds the engine operates only on the slow circuit. As a metered amount of air is drawn through the slow air bleed jet, fuel is drawn through the main jet and further metered through the slow jet.
5.5 Section 5 Fuel System and Governor 5 Main Circuit: (Figure 5-3) At high speeds the engine operates mostly on the main circuit. As a metered amount of air is drawn through the main air bleed jet, fuel is drawn through the main jet.
5.6 Section 5 Fuel System and Governor T roubleshooting Checklist When the engine starts hard, runs roughly or st alls at low idle speed, check the following areas before adjusting or disassembling the carburetor . • Make sure the fuel tank is filled with clean, fresh gasoline.
5.7 Section 5 Fuel System and Governor 5 Fuel Shut-off Solenoid Carburetors are equipped with a fuel shut-off solenoid, which also contains the main jet. The solenoid has a spring loaded pin which retracts when the key switch is ‘‘on’ ’, allowing the engine to function normally .
5.8 Section 5 Fuel System and Governor Float Replacement If symptoms described in the carburetor troubleshooting guide indicate float level problems, remove the carburetor from the engine to check and/or replace the float. Use a Carburetor Overhaul Kit (see page 5.

6.1 Section 6 Lubrication System 6 Section 6 Lubrication System General This engine uses a full pressure lubrication system. This system delivers oil under pressure to the crankshaft, camshaft and connecting rod bearing surfaces. In addition to lubricating the bearing surfaces, the lubrication system supplies oil to the hydraulic valve lifters.
6.2 Section 6 Lubrication System Figure 6-3. Oil Level Marks on Dip stick. NOTE: T o prevent extensive engine wear or damage, always maintain the proper oil level in the crankcase. Never operate the engine with the oil level below the ‘‘ ADD’’ mark or above the ‘ ‘FULL ’’ mark on the dipstick.

7.2 Section 7 Cooling System Coolant Recommendations Use equal parts of ethylene glycol (anti-freeze) and water only . Distilled or deionized water is recommended, especially in areas where the water contains a high mineral content. Propylene glycol based anti-freeze is not recommended.
7.3 Section 7 Cooling System 7 Figure 7-4. Coolant Levels on Reservoir . NOTE: Do not operate the engine without coolant in the system. Do not remove the radiator cap when hot.

8.3 Section 8 Electrical System and Component s 8 Overheated: Chalky , white deposits indicate very high combustion temperatures. This condition is usually accompanied by excessive gap erosion. Lean carburetor settings, an intake air leak, or incorrect spark timing are normal causes for high combustion temperatures.
8.4 Section 8 Electrical System and Component s Electronic CD Ignition Systems Operation of CD Ignition Systems Capacitive Discharge with Fixed T iming This system consists of the following components. See Figure 8-3. • A magnet assembly which is permanently affixed to the flywheel.

10.2 Section 10 Inspection and Reconditioning Inspect the crankpin for score marks or metallic pick up. Slight score marks can be cleaned with crocus cloth soaked in oil. If wear limits, as stated in “S pecifications and T olerances,” are exceeded, it will be necessary to either replace the crankshaft or regrind the crankpin to 0.
10.3 Section 10 Inspection and Reconditioning 10 Crankcase These engines contain a cast-iron cylinder liner that may be reconditioned as follows: Inspection and Service Check all gasket surfaces to make sure they are free of gasket fragments. Gasket surfaces must also be free of deep scratches or nicks.
10.4 Section 10 Inspection and Reconditioning 2. Use an inside micrometer , telescoping gauge, or bore gauge and measure the cylinder bore. T ake the measurement approximately 63.5 mm (2.5 in.) below the top of the bore and perpendicular to the piston pin.

10.6 Section 10 Inspection and Reconditioning Leakage: A poor grind on face or seat of valve will allow leakage resulting in a burned valve on one side only . Coking: Coking is normal on intake valves and is not harmful. If the seat is good, the valve could be reused after cleaning.
10.7 Section 10 Inspection and Reconditioning 10 V alve Guides If a valve guide is worn beyond specifications, it will not guide the valve in a straight line. This may result in burnt valve faces or seats, loss of compression, and excessive oil consumption.
10.8 Section 10 Inspection and Reconditioning Pistons and Rings Inspection Scuffing and scoring of pistons and cylinder walls occurs when internal temperatures approach the welding point of the piston. T emperatures high enough to do this are created by friction, which is usually attributed to improper lubrication, and/or overheating of the engine.
