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 Armature Magneto Spark Plug Wire

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

9 Cam Shaft- includes cam gear and cam lobes; driven by the crank gear 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 1. Cam Gear- portion of the camshaft that interlocks with the crankgear. Timing Mark

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

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

12 Crankshaft Counterweights-balances the forces of the reciprocating piston and reduces the load on crankshaft bearing journals. 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. 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. 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. 2. Wiper Ring- used to further seal the combustion chamber and to wipe the cylinder wall clean of excess oil.
