Hi guys, I was disassembling my engine when I noticed this. I can just barely catch my fingernail on it, and its tiny. I've had very mixed answers or suggestions on what to do. Some say that I should just leave it if "I just want it to run" and others seem to think it'll be okay. Also, there is one of equal size or smaller on the apposing side of the cylinder. Should I bother boring it? Whats the worst that will happen if I clean it up and leave it? its pretty far up on the cylinder, almost at the top. (I can't catch my fingernail on anything else but those two scratches and all other cylinders are fine)
