interrupted ignition

Hi all, I installed an electronic primary control on the Beckett AFG burner on my W-M hot water boiler. This gives me ignition for 10 seconds and then the spark stops. My question is: why is the flame so much quieter without the spark? The difference is dramatic, and I'm curious why-
Thanks, Steve

The ignition spark is blown away from the electrodes by the forced air. This creates a raspy sound as the spark gets longer and irregular. Sort of like a Jacobs ladder. As the spark reaches the wider top the spark gets louder.

Same with the ignition spark in an oil burner.
