Hey everyone, new member here so apologies if this is posted in the wrong place.

Does anyone know what engine is in the 2010 Troy Bilt pony 13AN77KS riding mower? I bought a used mower that needs a new ignition coil, but I can’t find the right part number. The parts manual for this model (Form #769-05404 on https://www.troybilt.com/en_US/manualsearchresults) seems truncated and does not have any engine model parts. Manuals from later years do have part numbers for all the engine parts, but the ignition coil does not look like the one on my engine.

I can’t for the life of me find the model number on the engine. It doesn’t appear to be stamped anywhere. There is a sticker on the housing that may have had it, but unfortunately it’s almost completely faded now. I’ve attached pictures of the only potentially useful information on the engine.

Look on the valve cover.. stamped on the top of it or on the side, or if someone took it off before, it may be on the bottom

Thanks, I did check the valve cover but didn't see a stamp on any side. Hard to see the bottom though so I'll try removing it tomorrow to look more thoroughly.

If you are looking at the cover and the OHV stamped into the cover is upside down then the number should be on the bottom. If right side up then most likely not there.

I just got the cover off, it was on upside down but there is no number anywhere on it...
