Looking at an engine that is attached to a lawn mower. He is claiming this engine has 22 hp but unless I'm mistaken I thought the TJD model only was like 18ish? He claims He had new pistons and rings put in it.... didn't know you could put bigger pistons in these. Anyhow here is the info on it
Model #TJD SPEC #367231 SER#5853972
Its got about 800 hours on it since a rebuild. Any advise or recommendations would be greatly appreciated.
