I have a Craftsman 917.288031 riding mower with Briggs and Stratton engine (model 31G777, type 0806-B1). It stalled while mowing the lawn and would not restart. I have drained all gas from tank and Bowl Float under carb. I added new gas and still no luck. I installed new gas filter, new spark plug and air filter, no luck. I checked compression by putting my finger over spark plug hole and it blew on my finger so compression was good. I confirmed the Fuel solenoid (699915) is working and it does pull down when IGN is on and push up when IGN is off so it is OK. It has restarted once or twice since it first stalled but sounds very poor runnig and stalls after about 30 seconds. Any ideas on what I should try next?
Now that spring is here its time to take out those Mowers but once it starts having problems it can be really annoying. While you are waiting on an expert to answer your question, I was searching the Manage My Life website and found some great links. I have attached the links below. Hope this helps!
There are a couple of different reasons and engine may run poorly, valves out of adjustment, dirt in the carburetor or a sheared flywheel key. It sounds like youíve covered most of the bases. Did the engine backfire when it stalled? If it did, the flywheel key was probably sheared. If it didnít it may be the valves. To adjust the valves you will need a blade type feeler gauge that has 0.04 to 0.06 blades on it. You will also need a wooden dowel or pencil.To adjust the valves follow the step below:
