  1. Starter Housing

  2. Choke plate

  3. Breather Assembly Breather Cover

  4. Intake Manifold/Venturi

  5. Carburetor Carburetor- provides the proper mixture of air and fuel to the intake valve

  6. Air Filter

  7. Magneto Spark Plug Wire Armature Magneto

  8. Valve Tappets Valve Tappets-Rides on the camshaft and pushes the bottom of the valve stem to open the valve

  9. Cam Shaft- includes cam gear and cam lobes; driven by the crank gear 1. Cam Gear-portion of the camshaft that interlocks with the crankgear. 2. Cam Lobes- egg-shaped protrusion on the camshaft that moves a tappet to open a valve; controls the lift and duration of the opening and closing of the valves Timing Mark

  10. Connecting Rod-transfers motion from the piston to the crankshaft and functions as a lever arm Piston Pin Crankpin Journal Bearing Surface Piston Piston pin Bearing Surface Rod Cap

  11. Crankshaft Crankpin Journal-attaches the connecting rod to the crankshaft PTO Journal Magneto Journal Bearing Journal

  12. Crankshaft Throw-measurement from the center of the crankshaft to the center of the crankpin journal. Determines the stroke of an engine. Throw = ½ stroke. Crankshaft-converts the linear motion of the piston into rotary motion. Counterweights-balances the forces of the reciprocating piston and reduces the load on crankshaft bearing journals. Crankgear-interlocks with the cam gear to turn the crankshaft

  13. Breaker points

  14. Piston Rings 1. Compression Ring-seals the combustion chamber from any leakage during the combustion process. 2. Wiper Ring- used to further seal the combustion chamber and to wipe the cylinder wall clean of excess oil. 3. Oil Ring-Wipes excess oil from the cylinder wall during piston movement. Openings in the ring returns the excess oil to the engine block.
