Small Engines (Lawn Mowers, etc.)/briggs and stratton lawn mower


Turned my mower at an angle to clean the underside.  The following day went to start it and am having difficulty getting it to run.   Made sure there was enough gas, checked the oil, checked the spark plug, pushed the primer button 3X and the mower will turn over but shuts down right away. Have tried priming it numerous times and it will kick over but quits right away.
I now realize I shouldn't have tipped it to degrass it but not sure what to do now?
Thanks in advance for some help.

ANSWER: What is the engine model, type and code number?  I need the information so I can look up which carburetor you have.

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.
