Thanks guys.  Unfortunately it’s not the max RPM setting, I checked that.  Sometimes it will read 13,xxx, just not consisently, and if I look at the min RPM for each lap, it’s typically 0.

I don’t think it’s the Mychron as I had it on the previous engine with no problems, and just swapped the engines out.  However I will switch with a friend’s mychron and lead and see if that helps.

The mychron lead is not wrapped around the spark plug wire– it is just attached using the plastic clip – I believe that is how the instructions said to attach it for a rotax, and that’s how it worked on my old one.  I’ll try wrapping it around a few times to see if that helps, unless there’s a reason not to do that.
