Has anyone ran into the situation of having oil in a cylinder after it has been sitting for awhile? Didn't get much of a chance to fly this winter but did go out and at least run the plane every month. Today when to go start the plane and when I went to burp the engine, it locked up as I pulled the prop through. I pulled the spark plugs and turned the prop and oil came squirting out of the #4 cylinder. I would guess about 8 ounces or more? Any thoughts
