I was wondering if anyone else had this specific problem I am having. I started cutting grass today and after about 2-3minutes, the lawn mower stopped and let out some minor smokes. After cooling it, the lawn mower failed to start. One of its symptoms that I think is causing this failure is the lock mechanism for pulling on the rope is gone. So regardless of if I hold down the bar or not, I was still be able to pull on the rope. However, the rotation was noticeably less smoother when not holding down the bar as expected. Other symptoms that I discovered today are dirty filter and a small crack on the metal part near the engine oil reservoir (there was a small leak of oil after I put some in today). I don't know how or when the crack got there. One more thing to mention, as I was cutting the grass, the sound my lawn mower made became progressively higher in pitch before stopping.
Any suggestions would be appreciated. Thanks.
