Nobody has yet replied to my earlier transmission, so I tried under a new subject...hope it worked.<br /><br />I touched on the subject once last week, but found little help. I have a 1986 115 Yamaha that I believe to be running rich. I know 2-cycles are notorious for smoking, but it seems a bit excessive. I flushed the engine today on the muffs and found after 5 minutes or so the grass under the the prop was a bit blackened (with oil).<br /><br />The engine runs great. However sometimes on idle a bit rough. She has died out just a couple times as I put it into gear (which I associated it with running rich...). Is this a potential problem, or an easy fix? <br /><br />It is an oil injected engine, I would assume there must me some type of adjustment to fine tune to fuel/oil mix?!?!?!<br /><br />any input would be much appretiated
