Thread: misfire issue, out of town and no tools

Yup, chipped piston. Hell I ran the first motor for what...almost 3 weeks before I eventually had some help pulling the head off and finding #3 toasted. I replaced the plug a couple times too.

Yeah, you chipped a piston. It is only a matter of time before it goes and leaves you sitting. Not telling how long, maybe tomorrow, maybe 2 months. But it will cause issues.
