Small Engine Troubleshooting Problems? Ask a Mechanic Now.
What engine do you have? Single cylinder? When engine quits, how long before it will restart?
Engine has to loose spark or fuel. If it has no spark when it quits, tested with a spare spark plug attached to the spark plug wire and grounded while cranking, your ignition coil/magneto is bad and needs to be replaced. If it has spark, we have to assume it is loosing fuel. Does it have an electric solenoid in the carburetor? Does it have 12 volts to it when the key is on?
Is battery voltage good, and you do not have to jump start the engine?
I see question is still open. Did you see my response?
