That's a good chart, big blue.  However,  I'm interested in the color of the spark, when the plug is grounded outside of the head.

Sorry, I think the spark color for a good current should be white or blue/white. If it is yellowish the ignition may be weak.

My spark is white, which I've never seen before and which is why I asked.  Scooter was running but never well.  Now it won't fire.   Looks like I need to test some components.  Thanks for your input.  More input welcomed.

Put your finger on the plug electrodes, crank it: if your face turns white or blue you are good to go.
