Valves: Intake and Exhaust
- Controlled by camshaft (driven by timing chain).
- Intake valves let air-fuel mixture in; exhaust valves release combustion gases.
Carburetor System
- Usually dual single-barrel carbs in early models.
- Mixes air and fuel before delivery to the cylinders.
- Located atop the engine, connected via linkages.
Cooling System
- Finned engine block and cylinder heads increase surface area.
- Air flows over fins to dissipate heat.
- Air intake via the oil bath air cleaner.
Ignition System
- Includes distributor, points, condenser, and spark plugs.
- Proper timing crucial for engine performance.
Electrical System
- Alternator or generator supplies electrical power.
- Battery, wiring, and switches support various functions.
