Thanks Starfire.
I believe those are the latest numbers for the individual ignition coils. This engine also has the spark advance module that was used for a while. If memory serves me correct, there is a required wiring harness change, too, that gets rid of it.? I forget how I tracked down all these numbers last time. Is there any other way to find parts if a person doesn't have a contact with Kohler? Wish I'd made some notes last time I saw one of these. I only remember enough to be dangerous!
Also, is it possible it's 2 or 3 terminal instead of 1 or 2? I seem to recall something about that.
