The #1 most common problem with small engine is "dirt" blocking some passage inside of the carburetor. The quick way to verify this, remove the air filter and spray a little carburetor cleaner (or use a squirt bottle and gasoline) straight into the carburetor throat. Do NOT choke the engine, turn the switch ON and pull the starter cord. It it starts and die, you have a blockage somewhere in the carburetor. If you plan on cleaning the carburetor yourself use a flashlight and check into the fuel tank to see if there is any debris in there that will cause the carburetor to get clogged again.
If removing the air filter and shooting cleaner/gas into the carburetor is difficult, you can remove the spark plug ad add a VERY SMALL amount there.
The #2 most common problem is an issue with the oil level and/or its sensor. If you are certain the oil level is correct, disconnect the oil level sensor and see if it will start.
#3, but really not that common, is a bad spark plug. You should always have a spare spark plug on hand. Use a known brand name (NGK, Denso, etc). Finding the right spark plug could be difficult, so shop SparkPlugs.com
I’m reading several forums and the low oil sensor seems to be an issue. I’m just not sure what to disconnect to see if it will start.
