I think you have to be careful with the wording too.

AMT used to call their start system "full auto start". And it was an air starting system. I don't know if they still call it that.

I personally divide the two different types as "air start", and "on board auto start".

And referring to AMT engines with a starter motor as such, "AMT with electric start".

Most the time you can refer to AMT engines as "back breaking support equipment", and those with no sense of humor won't laugh, but will know what you are talking about. I think Eddie Weeks "Auto start" weighs about 350 lb's and is carried (read as dragged) on a dolly to wherever he needs to start.

I've found that with electric start engines, (jetcat, merlin, artes, etc) that you can "manually start" them by regularing propane off board with no solenoid, and get smoother starts. I started doing this a couple of years ago, and have been preaching it to others. You're basically starting by the sound of the engine, same way the AMT air starts were doing, without having to bring a scooba bottle. Any problems and you shut the propane off right away, no more fire, so to speak.
