I checked the spark plug, which is new, and it's definitely oily. I'm assuming one of two things is wrong, stuck rings from sitting outside for two years, or worn rings. Any suggestions on what I can try to get the rings un-stuck? Assuming that's the problem of course. Yamaha sells a product called Ring Free that might help with your problem, it is sold online at the usual places as well as marinas and snowmobile shops. I would pour a small amount down the spark plug hole and let it set for a day or two, then add some to your fuel. Also check to see if your crankcase breather is functioning correctly.

I'll look into Ring Free, thanks. It didn't even dawn on me that the crankcase breather could be an issue. This thing was covered with mud dabbers and other creatures both large and small. I'll check it tomorrow. Thanks! Edited 4 hours ago by BradKahler Share this post Link to post Share on other sites

Had a 310-8 that smoked like that but ran like a top and mowed with it for a few years like that. I did have to keep an eye on the oil though. Rings may be stuck or just worn, mine had a broke ring . Hope yours will straighten out with the ring free. 1 Share this post Link to post Share on other sites
