Kohler command 20 hp fouling plug low hours

I have a 2003 walker mower with 267 actual hours. It is already burning a lot of oil on the front cylinder. I pulled the plug today and it was covered with carbon. The back plug looks great. I just rebuilt one of my other Kohler engines with same problem, but it had almost 900 hours. The 900 hour engine had a small oil leak that covered the fins of front head and clogged them up with dirt. The heat made the oil ring fail. I looked and the front fins on the 267 hr motor were clean. Any other idea why the engine might have started burning oil so soon. I am assuming that the oil rings have failed. just like the other engine.

Sounds like the classic blown head gasket at the oil return port, A cylinder leak-down test will verify this.

Makes sense to me. It seems like a lot of the newer v-twins burn a decent amount of oil. My friend had a Briggs Intek that would go through tons of oil.
