When inspecting ignition components, what is evaluated?

When inspecting ignition components, the primary evaluation focuses on the presence of spark. This assessment is critical because the ignition system's primary function is to produce a spark that ignites the air-fuel mixture in the engine's combustion chamber. If there is no spark, or if the spark is weak or inconsistent, the engine will not start or run efficiently.

Evaluating the spark involves checking the spark plug's condition, the ignition coil's functionality, and the overall ignition timing. A strong, consistent spark is necessary for proper combustion, which directly impacts engine performance, efficiency, and reliability.

While other components like fuel quality, electrical wiring integrity, and oil levels are essential for the overall operation of a small engine, they do not specifically pertain to the ignition system itself. Ignition system issues primarily revolve around whether or not a spark is being generated, making this evaluation crucial for diagnosing ignition-related problems.
