Small Engines (Lawn Mowers, etc.)/Oil out of exhaust

Question
Hi Eric-

Had to replace the front tire on my Swisher Ride King mower. Instead of tipping it to one side like when changing the blades I made a cradle and tipped it up on the back tires and top of the seat so I could work on the front tire assembly easier. Took the tire off last night and didn't notice anything odd but this afternoon after getting a new tire/tube there was oil all over the floor and it came from the muffler. Other than the obvious of checking the oil what do I need to do before trying to start it again?

Thanks,
Jim

Answer
Most likely gasoline entered the engine oil through the carburetor.

If the oil is thins, runny and smells like gas you need to change and re-fill with oil before using the mower.

I would recommend removing the spark plug and turning the engine to remove any oil from the cylinder.

If you fill your full tank and let the mower sit overnight, does the fuel level in the fuel tank decrease?

Experience

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
