Murray Lawn Tractor periodically shuts down

mulling · 06-26-2008, 08:22 AM

I have Briggs and Stratton 18.5 hp OHC engine, Model 31N707, Type: 0233E1, Code 0311177E; which periodically shuts down. I have not been able to isolated any particular reason/event which causes this. The engine will not restart an aggravatingly long period of time(5 minutes), unless I remove the fuel solenoid connector and replace, then it will start. I cannot find any information on what controls the ground lead, very poor/no schematics for the ignition switch, etc. Event seems to occur with both constant and increased effort. Am at a loss, any ideas would be appreciated. Thanx

When it shuts down, turn the key ON, then OFF, while listening near the fuel solenoid connector. If you hear a click, the fuel solenoid is functioning properly. If you do not, clean the connection, if that does not fix the problem, replace the fuel solenoid. Also, when it shuts off, remove the spark plug, connect the boot, rest it against any metal part of the engine, and turn the engine over (check for spark). If spark is present, it's not ignition related. If no spark, possibly the coil.
