I have a Snapper self propelled walk behind lawnmower, Mod# RP21500T2. The mower is in good shape. But the motor 2 cycle, Mod# FTYXL8408456F is shot. Is there a replacement motor that will fit on this mower?
I don't now if you have a parts book, but these are listed as alternate engines. View attachment Snapper cross ref.pdf If you want something more modern I suggest you measure your bolt pattern, shaft length and size, location of controls etc.
You can contact online companies like tewarehouse.com and they can cross reference your engine to something more modern as well.
