"Hi, i just bought a 95 yamaha 25hp oil inject. a few mts. ago ran great. Now it's starting to foul plugs up, on trolling speed, not both at the same time. Is it the type of oil that causes it. I've tried different types.Tried some yamalube ran it for 7hrs at low idle plugs looked good.Just wondering if it could be the oil or something more serious."
