I just replaced my plugs in my Merc 125.<br />After running it for a few hours, the plugs are really oily. <br /><br />What does that indicate?<br /><br />Compression is 140 on all cylinders.
It is. I'm got an oil injector and I add a little to the tank for for good measure.<br /><br />Are oily plugs indicative of any problem other than fuel/oil ratio?
