I purchased a Murray lawnmower from Walmart. It worked for about a month then it would not start. I took it took the Murray dealer and they said it was the engine and wanted to put another one in for a $ 1000. Walmart refuse to give me another mower. ALso the Murray company says that part of the engine is not covered.They said the warranty is out. What I need to know is where can I purchase a 17.5 HP engine at a reasonable price.
