Yup they said they can see it in the journals or whatever. Stihl ultra is the worst mix to use, I expected better from such a world renowned company.
Moved from Stihl to Echo 7310, so far, so good

Here is an Echo 7310 that is holding its revs pretty good. Im glad to see that Echo is building something that can be worked on. 9hp on Joe's Dyno is something special.

How is the HP gain determined from the dyno, (rated HP*measured torque)/(stock torque)? I don't know a ton about porting, but isn't 70% gain in HP quite a lot for a port?
Look up dyno joe on YouTube
No truer words were ever spoken!!
I've had decent luck with echo dealers and repairs.
My Echo CS-670 still runs very well and I am glad I still own it. Always starts and always runs:
I include the second Pic to let you know that it is easy to adapt a Stihl bar to operate it. I made that adaptor in my shop with a hickory strip and have made others using plexiglass.

I saw in the first post the comment about the echo chain……
While at home depot the other day I checked out the echo boxed chain for sale, and it has Oregon stamped on the chain ,
Just thought that was interesting.

I've always had good luck with Oregon and I'm a bit of a fan boy
. I took off my echo bars which are Oregon I believe and installed Oregon branded bars 
Just got a 7310 and it's everything I expected, only on tank #4 but it's coming to life and just rips with 24" X-cut chain. This is the keeper 70cc saw for the long term.

I bought an adapter for my CS 590 to run a 20 in stihl bar and it’s been great. Proper 72dl bar instead of the 70dl it came with.
For the 7310 to fit a 84dl Stihl bar with an adapter it needs to have the adjuster hole drilled out to fit it. The stihl bar test fit a ok on my Husky 372 with the adapter but the 7310 needs more space, they have different bar adjusters apparently. Maybe taking a drive link or two out would help but I figured y’all might want to know.

A couple years in and mines going strong. It’s got really good torque for a 70cc saw, reminds me of my old stihl 660 power wise but it’s a couple lbs lighter.
