Small Engines (Lawn Mowers, etc.)/push mower shutting off


I have a push lawnmower that worked fine until yesterday. I started to sound like it was running out of gas then shut off. I had to primer it to get it to start then about 5-10 minutes later it did it again. Also the primer button takes forever to pop back out to repush it.What could be the problem,thank you!

Most likely a dirty carburetor.

I'm not sure what engine you have but there are lots of videos on You Tube showing how to clean small engine carburetors.

You might have a Briggs and Straton or a Tecumseh engine.  These are very popular engines for late model mowers.

If you want to send me the engine brand along with the model number I may be able to provide a more precise answer.

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.
