I may have a carb issue myself. I believe fuel is slowly getting into my oil. A month ago at the tech event I drained about 5 or 6 oz of oil to bring it back to par, but tonight I drained another 4 or 5 oz's again, to bring it to the top. Now, it either wasn't level last month and needed to drain even more to make it level or my carbs are working overtime. My machine is 21 years old and wonder if there are components inside the carbs that need attention. I am currently running sea foam in my tank as I've read about that stuff and will watch the looking glass to see if the level keeps climbing. Don't want to run too long if fuel is thinning my oil right?
