Hi Evansaw,
I don't want to doubt the source of your information but it astounds me that Stihl does not continue equipping its professional chain saws with fuel injection to underline its position as a technology leader. Certification of new chain saws in line with new EU emission regulations becoming effective this year suggest that fuel injection would facilitate to fulfil new emission standards due to its numerous parameters being sensed and the exact amount of injected fuel calculated in real time thus reducing raw emissions. For this reason it can be assumed that Stihl will continue with fuel injection in the long run. It seems to me that the mentioned 400 c-m is carved for a specific market niche in the interim.
