What does an orange spark mean on a spark plug?
A yellow/orange spark signifies weak ignition.
Which is more effective blue or orange sparks?
Orange sparks are like slow sparks that miss fire and creates other problems, so blue is more effective and that’s how ignitions are designed to properly be efficient. Orange sparks could mean ignition problem in the coil, a bad ground or too much resistance.
Why do ignition spark colors change over time?
I replaced it, and got a blue spark back, along with a much improved engine performance. On an automobile ignition system the spark should be bright blue. That’s because the compression ratio is higher than that on an air cooled small engine. An automobile engine operates under a transient condition where the RMP’s change so fuel demand changes.
Do you know the color of a spark?
Anytime the spark and the air/fuel are inside the envelope, there is ignition, regardless of the color of the spark. The spark needs to be bright blue. Also, you need to use a spark tester, NOT an old plug.
Where does the Orange and yellow spark come from?
Orange and yellow come from particles of sodium in the air ionizing in the high energy of the spark gap. However, they are talking about small air cooled engines, and are using a specific Briggs and Stratton spark tester with a fixed gap for small air cooled engines, the 19368 model.
What’s the difference between Blue Spark and orange spark?
Blue spark is cold in comparison to ultra-violet. Orange and yellow come from particles of sodium in the air ionizing in the high energy of the spark gap. However, they are talking about small air cooled engines, and are using a specific Briggs and Stratton spark tester with a fixed gap for small air cooled engines, the 19368 model.
