What do gap gauges measure?

Gap gauges are specialized tools designed specifically to measure the size of gaps in various components, particularly in the context of small engines, such as spark plugs and armatures. In the case of spark plugs, it is crucial to have the correct gap between the center electrode and the ground electrode to ensure proper ignition and engine performance. If the gap is too large or too small, it can lead to misfires or inefficient combustion.

Using gap gauges allows technicians to achieve the precise spacing needed for optimal engine function. Similarly, in armatures, proper gap measurement ensures efficient electromagnetic interactions, which are vital for the effective operation of electric motors and starters in small engines. This focus on accuracy highlights the importance of gap gauges in maintaining engine efficiency and performance.
