No, I just put a new 120 euro carb on there without doing any sort of investigation whatsoever, ignoring the huge resource that AS could be, and ignored any information on the internet as to what the causes might be or how to correctly use the new carb.
Anyways,
Yes - of course I did the factory reset(which is a bit overrated as a fix if you ask me, as the thing seems to set itself as you use it anyways).
I have also tried modifying the metering lever as well. And other aspects of the carb. The MTronic would always eventually respond in a manner that made the mods work less or worthless, or even cause the metering to go to one extreme, or the other, and basically make the saw unusable. I suspect a sensor wasn't working, or the parameters weren't wide enough to compensate, or otherwise unable to compensate.
The problem likely seems to be the earlier carb version mechanically, or early firmware, or both. The best part was I got this in trade, and was curious to see how reliable it would be, as I was in a debate about how reliable the new MTronic system was with some fans of it beforehand.
The point is, both manufacturers have made saws that weren't perfect, and have not stood behind them because a recall across the board on saws that 'mostly work' doesn't make sense financially.
I have used both manufacturers saws in some grueling professional work, in some of the worst weather, and they both have performed similarly. But, in pro work - there's all manner of things that kill a saw that have nothing to do with the saws design.
