Pete, I don't know the answer to your question but what you probably need to do is figure out why it is missing starts in the first place. I have been running kero start on the Jetcat's for a couple of seasons now and it is my experience that failed starts are rare. You may have to bump up the amount of fuel that is being introduced into the turbine on start up, which can be increased in the ECU. I suppose there can be other issues but this is the most common reason for a missed start. Kero start is typically very reliable.
