At the very end of this season, my Atomic 4 starting producing white smoke out of the exhaust. The spark plugs were very sooty so I replaced them. Smoke continued even after a long warm up. The local marina came out and said that "they suspect that there is a valve that is sticking or not closing all the way. There is a definite miss when idling and there is a bit of a pop sound. Also smelled unburned fuel in the smoke. Head will need to be taken off and work done on the valves."
Does this make sense? What is the next step in diagnosing/fixing the problem?
