My murray lown mower wit an 11 horse briggs and stratton engine ran great for a couple of houres and then it wouldn't start and I put a new spark plug in and still no spark. Is it my magneto? How do I check the magneto? And where can I get a new one?

Its not a new tractor at all though

I meant with not wit

Hi,
You are new so I broke your post free of that five year old one. Please advise as to the engine model number. There three possible models that could easily have an 11 HP decal, and it does matter; give my the type as well and I will give you a link to the parts manual.
Peace,
Clarke
