That is awesome and we have surprises almost every day.
I figured it was a bigger saw by the size of those dogs.

So then it is a direct injection right into the crankcase.    How cool is that.   It must be worlds smallest injector.

Yep SDI  (semi direct injection) right into the crankcase only requires low pressure and the injector is not exposed to the combustion  process.

Good video showing how it all worked on the TS500i cut off saw. Just trying to learn what is on the updated MS500i.

Video is 5-6 years old

IIRC someone posted on AS a year ago or so about all the issues with the TS injector and did a complete tear down of one to show all the components and where they fail. Better hope they worked the bugs out of it compared to those saws because a new injector  for them is $200

This video is posted in the CR G.  Cant figure out how to download to repost here. But see if you can see it.

Stihl fuel injected chainsaw. Sorry not impressed with these cuts. Like something is wrong with it or something.

I wasn't impressed with the operator rocking and rolling it in the cut.
Looks like he ran it from cold.
Stihl UK site from Dec. 2017 says production starts in 2018 and available in Great Britain early 2019.
Best power to weight I've ever seen for a factory 80cc saw. 13.669 lbs.
MTronics specs sounds super hyper too.

I know what the specs say. But dang that is a turd in those cuts on video JMO.  462 looked way better.
