064 worked well, I learned things today.

I swapped the piston last week for a new Meteor piston.
It runs stronger now, I was playing with a square ground chain on it, and that was cutting really nicely.
Ran two tanks, but when I went to use a 3 corner file to "touch it up". I learned another lesson. I had over heated a few cutters, File had a hard time trying to sharpen them.
So, even if it looks ok, it is really easy to overheat them...

The carb spitting back is reduced with the new piston some. Maybe the cylinder is worn some too...?
It sure did run well for me today tho.
This was one tank of cutting:

You think you overheated Cutters with a hand file? Roll eyes

Simmington swing arm grinder, but then... I wanted to touch it up with a file.
I know it is difficult to achieve the correct angle by hand, but the only way to learn is to try!
and I re ground that chain, and could see just how far off my hand filing was. oh my...
