I have a I have a troy bilt super bronco riding lawn mower that was manufactured sometime between 2004 and 2005I owned it since that time it has worked great but couple of weeks ago when I was out mowing my back acreage I stopped It shut it off and when I went back to start It, it would not start. We found out that a push rod was bent and then some internal problems with the engine. Since the tractor was in such good shape I called small engine warehouse give them all the specifications They gave me a choice of 2 motors The 1 that was ordered was closest what I had in the tractor And it arrived A week later. My handyman has put it into the motor space it fit without a problem we should be finishing installing it and starting it within the next couple of days. When I recommend small engine warehouses Yes I would I got good service and the price was what I could not afford a new riding lawn mower did not like what the choices were out there because I need to keep both hands on the wheel and not 1 on some lever that controls the speed
