Help me with my Yamaha 115
I have a 2000 Yamaha 115 2-Stroke that has given me years of reliable service. Recently the fuel mileage has dropped significantly, it's running a little rough at lower RPM's, and the spark plugs are wet with fuel/oil. What is likely going on?
Just my guess
If all of your plugs look the same I would suspect fuel contamination. Try smelling them and see if they smell "wet". If only some of your plugs look this way it could be a number of things and I would perform a compression test to rule out mechanical issues first.
