Hello Ryan7293. Welcome to our Do-It-Yourself Web Site and our Small Engine forum.

When an engine simply fails to start, the cause is most likely no spark at the spark plug. There could be any number of reasons why there would be no spark.

Most likely the spark plug is defective or fouled. The easiest fix is to replace the plug with a new one and retry starting the engine.

If changing the plug fails to provide any spark and the engine still won't start, check for a grounded on/off switch or lever. Usually these parts are located on the engine and operated by the throttle speed control lever secured on the handle.

If there is spark to the plug, there may not be any fuel getting into the carb or the carb is gummed up. If this happens to be the case, remove the spark plug, add a few drops of fuel into the spark plug hole and reinstall the spark plug. Attempt to start the engine.

If the engine starts briefly and dies, the carb is gummed up or it's not getting fuel. Check the fuel lines, fuel filter and fuel flow rate by removing the fuel hose at the carb.
