I had a lot of problems with the early MTronics. Major hot starting problems and burning through solenoids. The newer versions seem more durable and I love how they hold the saw high in the power band.
AutoTune had even worse hot starting problems in the beginning. So bad that I now avoid them. Multiple friends complain their 550mk2 has to be half choked or trigger started. I haven’t run mine enough to know.
In both MT and AT, a computer carb with vapor lock is dead in the water. A standard carb can often be choked and half throttled until the carb cools down enough to run. Not to mention I hate paying for proprietary computer parts. So I guess I’m not a fan.
But I’m in the minority. Most people like them.
