In 2006 I bought a Troy-Bil Pony Mower, after years of small issues, the valves had to be reset. That worked for a while, now I need to change the cam, the compression release is bad. The issue I have, the 17.5 B&S motor valve cover was not stamped, so I don't know the true model number on the motor. Need the model number to get the correct cam. Any ideas?

Export threadI don't remember when they started stamping the valve cover as opposed to a riveted tag or stamping the blower housing. There isn't a chance that the valve cover is upside down and the model number is on the bottom.
Take pictures all the way around the engine. Post them up here. Can also take an oily red shop rag and wipe all around. The dirt and oil help highlight the stampings if yours has them.

I have taken the cover off to reset the valves, cleaned off cover & looked.I don't remember when they started stamping the valve cover as opposed to a riveted tag or stamping the blower housing. There isn't a chance that the valve cover is upside down and the model number is on the bottom.
what are the chances the cam will have a part number on itI have taken the cover off to reset the valves, cleaned off cover & looked.
It is likely a 31R series (my JD D105 has a 17.5 hp b&s). Mine is a 31R977 and for giggles and grins I went to the B&S site, and looked at several of the 31Rxxx IPL's and they all use the same cam (793880).
