I guess this had to happen... once..
Saw has worked for maybe 5-ish hours after rebuilding it a year ago.
Brand new Meteor piston and Caber rings.
I am not entirely sure, but i believe i did check ring gap, and deburred the port.
After grinding, port width ended up being 32mm or 61.5% of total bore diameter.
Ive read a few articles where exactly this happened with caber rings.
Cylinder and piston are "reusable" but whats the point of putting a new ring if this will happen again.
Opinions ?

On the second pic it does look like it caught a ring on bottom side of the port.
