my engine is OLD, like as in 12 years old 40 FP engine. The Piston didn't show signs of scoring, and isn't hitting the glow plug. But I cleaned it up, got some castrol gum out of it, cranked it with the glow plug out, and as soon as I finish my new engine mount (I make em out of plywood, but the keep breaking) I'm putting it back in and trying again, although I'm still not exactly sure what's going down
