What is a sign of a healthy ignition system in small motors?

A sign of a healthy ignition system in small motors is that the engine runs continuously without stalling. This indicates that the ignition system is functioning properly to deliver a consistent spark to the engine at the right time, allowing for smooth operation. A well-maintained ignition system ensures that the fuel-air mixture ignites correctly, providing reliable power and preventing interruptions during operation.

In contrast, frequent spark plug failures suggest issues in the ignition system, possibly due to improper fuel mixture, excessive heat, or faulty components, which detracts from the health of the ignition system. Intermittent power loss is typically a sign of irregularities in firing, indicating problems within the ignition that prevent consistent power delivery. Lastly, black residue on spark plugs points to an overly rich fuel mixture or incomplete combustion, which can lead to inefficient engine performance and is a sign of ignition issues that need to be addressed. Therefore, continuous engine operation without stalling is the hallmark of a healthy ignition system.
