Piston and Connecting Rod
The piston and connecting rod of the 14 hp Kohler engine work together to convert the reciprocating motion of the piston into rotational motion of the crankshaft. The piston is made of cast aluminum and features piston rings that seal against the cylinder walls. The connecting rod is made of forged steel and connects the piston to the crankshaft.
Crankshaft
The crankshaft of the 14 hp Kohler engine is the main rotating component that converts the reciprocating motion of the piston into rotational motion. It is made of forged steel and features counterweights to balance the rotating assembly. The crankshaft also has journals that support the connecting rod and main bearings that support the crankshaft in the engine block.
Carburetor
The carburetor of the 14 hp Kohler engine is responsible for mixing air and fuel in the correct ratio and delivering it to the combustion chamber. It is a float-type carburetor that uses a needle valve to regulate the fuel flow. The carburetor has several adjustment screws that allow the operator to fine-tune the engine’s performance.
Ignition System
The ignition system of the 14 hp Kohler engine is responsible for generating the spark that ignites the air and fuel mixture in the combustion chamber. It uses a solid-state ignition module that is triggered by a magnet on the flywheel. The ignition system also includes a spark plug and high-tension wire.
