Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** will be assisting you.
How old is this machine? Can you provide the model and type number from the engine so that I can better assist you?
Thank you for the information.
Does the engine start easily?
What have you already done on the machine? Did you have the carburetor apart?
Have you looked at the flywheel key? It could be that it is sheared slightly causing the ignition to be out or time slightly which could cause poor running situation. Briggs had a problem with some of these engines there is a service bulletin issued in regards ***** ***** issue. Briggs basically changed the flywheel key to a different material and increased the torque spec on the flywheel bolt/nut.
Did the machine just start doing this all at once?
Take a look at the flywheel key and see if it is possibly sheared. It is probably not totally sheared because it will start and run but it could be partially sheared which would cause some running issues. Let me know what you find. I can send you over a copy of the service bulletin if you would like.
Here it is.
