This could be caused by a couple things; carbon build-up on the head, valves not seating properly, intake manifold air leak, blockage in the carburetor, etc. Please take the unit to an authorized Briggs & Stratton service dealer for diagnosis. You can locate one here: http://bit.ly/14yWuSi

Oil leak ing from caborator when engine running what is causing this?

Asked by: pg23
Oil in the carburetor or air filter is likely coming from the breather. You will want to make sure that the breather tube is not bent, kinked, or clogged in any way. If it is not you may need to replace the breather tube. You will also want to check the o-rings and seals on the dipstick assembly to make sure that they are intact.
