What is the proper breaker point gap in a small engine?

The proper breaker point gap in a small engine is typically set at 0.02 inches. This measurement is crucial because the gap influences the timing and efficiency of the ignition system. When the breaker points are set correctly, it ensures optimal spark generation, which is key for engine starting and performance.

A gap that is too wide can lead to a weak spark, making it difficult for the engine to start and run smoothly. Conversely, a gap that is too narrow can cause the points to burn out prematurely due to excessive current flow. Setting the breaker point gap at 0.02 inches strikes a balance between these two extremes, promoting reliable ignition and overall engine functionality.

The accurate setting of the breaker point gap is a foundational aspect of small engine maintenance, affecting many components, including fuel delivery and engine timing.
