    Here's some things to check:
    1. If you want to check spark, remove the spark plug and make sure the body of the spark plug is in contact with a grounding source (unpainted metal) on the motor. Pull the motor thru while watching the spark plug gap. Clean tip and arm with fine sand paper if dirty, spray with carb cleaning spray.
    2. Check the oil level... many of the small motors have a switch that will keep the motor from running without proper oil.
    3. smell th fuel and make sure it's not "old" smellling...

Briggs & Stratton Modle# 100000 will not stay started.


your engine is only running on the fuel you are pumping in, the carb. is not lifting the fuel on its own, maybe because of water in the bowl or dirty jets. You must take the bowl of and clean it out and depending on the type of carb. it might need a new diaphragm. Stephen.
