I think I did some damage the last time I ran it last year. When I was almost though the traps, it started making a sputtering sound. Now, I finally got around to look into it. The spark plug in # 7 had a bent electrode like something hit it. I did a compression test, 175 lbs in all except # 7 was 151 lbs. I put new plugs in it, started a few times to move it on and off the trailer and so far no bent plug. I looked in the cylinder through the spark plug hole with a camara and didn't notice anything bad. Any thoughts before I pull the head? Bottom end only has 19xxx original miles. I just hope I didn't damage a brand new TFS cnc 215 head.

Maybe that plug was dropped on the floor when putting them in the last time?

Just pull off the head and verify, it is much better to be safe than sorry. 24lbs in one cylinder on only 19xxx is an identifier to something imho

No, I didn't drop it.

Good ole' no. 7. Past experiences tell me you have a fried piston. Good luck!

there is only one way to be sure and with losing that much comp over one cylinder would indicate some sort of bad news.
