Does anyone know where I can find the correct valve settings for my B&S 17.0 HP I/C OHC mower motor? I can't find a serial number to it anywhere. My mower is a Murray 425007x92 and its approx. 7 years old.

-What I found was .003"-.005" for the intake, and .005"-.007" for the exhaust. I used the smaller values for both when adjusting the valves on my Brother-in-law's John Deere...

Yeah, if we had a model/type/code number, we could agree on a correct setting.
