I recently bought an XP550 because I thought some catastrophy had befallen the trusty 437XP. and I had no time to sort out the loose cylinder fasteners.
But the xp550 grates on my sensibilities when turning high revs. It's that "lean" burble that gets me. I can do OK with the rich burble...
The selling dealer said just today, "auto tune runs on the edge for EPA."
I'm wondering, Just what is the feed back sensor for these auto tune power saws?
I wish they would have a high speed screw. Low speed/idle, Auto tune is fine by me!
