Yep 5000 rpm and bang no rodYou can pretty much assume that the weakest part of most small engines is the connecting rod. If you find it interesting to read about high performance small engines, try here: https://4cycle.com/karting/
Mowers with pressure fed big ends can go a bit higher but usually the little end simply snaps off
When doing racing mower engines, the rods have to be changed unless you are just runny one for the kids to play with
