This is an authentic replacement part manufactured for use with Craftsman walk-behind lawnmowers. The blade is angled to allow the clippings to rotate through the cutting deck to produce fine clippings for side discharge and mulching. Lawnmower blades wear out over time and can cause the grass blades to tear making frayed endings that can diminish the look of the lawn.

Its propose is to deliver an electric current from an ignition system to the combustion chamber of a gas fueled engine.
It will ignite the air fuel mixture by the spark.

Over time a Spark Plug will become fouled because the air/fuel ratio may be set wrong,worn piston rings, carbon build up and other factors.
It is better to replace a fouled spark plug, rather then trying to clean it.

A carburetor basically consists of an open pipe through which the air passes into the inlet manifold of the engine.
The pipe is in the form of a Venturi: it narrows in section and then widens again, causing the airflow to increase in speed in the narrowest part.
Below the Venturi is a butterfly valve called the throttle valve — a rotating disc that can be turned end-on to the airflow, so as to hardly restrict the flow at all, or can be rotated so that it (almost) completely blocks the flow of air.
This valve controls the flow of air through the carburetor throat and thus the quantity of air/fuel mixture the system will deliver, thereby regulating engine power and speed. The throttle is connected, usually through a cable or a mechanical linkage of rods and joints.

Fuel is introduced into the air stream through small holes at the narrowest part of the Venturi and at other places where pressure will be lowered when not running on full throttle.
