Sounds like a good idea.

RE testing the spark, how do I do that? Start the motor with one of the plugs removed, put it on the motor block and look at the spark?

Or: remove one of the spark plugs, turn on ignition, turn the motor over? I have a push-button in the motor room to switch on the starter.

And I suppose the 'snappy blue spark' will be kind of obvious, and easily distinguished from a weak non-blue spark?

Sorry, I am pretty new to this diagnostics things. As I said the A-4 ran smoothly for years and years....
