What happens if the spark plug gap is too small?

Answer 1

If the spark plug gap is too small, it can lead to incomplete combustion, resulting in rough engine performance, reduced power output, and decreased fuel efficiency. The spark may not ignite the air-fuel mixture effectively, causing misfires and increased emissions. Additionally, the engine may experience difficulty starting or may run unevenly. Overall, maintaining the correct spark plug gap is crucial for optimal engine function.
