This would affect cylinder wall lubrication and could.
I can barely feel it but it s enough to worry me.

Thanks everyone for the information and if anyone else has any advice on doing the cylinder honing i am all ears.
I thought i would show you a little experiment i did on an 036.
The saw was my father in law s and he gave it to me saying it was hard to start etc.
Well he was right but it did start after a while.
If i can hone it out can the rings be adjusted to fill in the couple thousandths that are honed out.
Ok so according to the bgb for the gen 3 the cylinder bore limit for the stock pistons is 86 23mm and i am at 86 013mm at the moment on that cylinder with the scratches so i will be fine.
It also seemed to idle okay and had.
The scoring on the cylinder wall is not that bad i would say but a finger nail could catch.
My plan is to split the crankcase open to remove all debris change bearing and oil seal and put a new piston kit in it.
Zero dollar fix for scored piston cylinder hi guys.
Or should i just do a light ball hone and install the piston anyway.
