How do these cylinder walls look to you?

Signs of dirt ingestion from the bottom. Looks like a ring groove at the top. No signs of crosshatching so worn .005+
 
hone and new rings. Too expensive to go oversize and bore. Look everything over and measure it before proceeding as other things can be worn out too.
 
If you have no measuring tool for the bore and the cyl looks like a hone will suffice , check the ring end gap . Feeler gauges are cheeeep . There are videos for that procedure and what's tolerable .
 
It's a mower cylinder. Looks brand new to me. Run it till she pukes.

You guys need to get drastic on sealing your air filters. I've used the below on all mine so far. Will leave alone till she needs a few extra pulls or cranks. Then pull apart and install a new filter.

Never pulled a carb off and looked down the intake tract and found a clean pathway. Always had a grit coated interior on the pipe/manifold. These filters do not seal 100%. Mine do now.

In order to check the ring end gap with a feeler gauge, you have to dismantle the entire engine. A bit impractical wouldn’t you say, unless you are rebuilding it?!
