Hot start issue after seafoam

So the other day my car flooded pretty bad so I wanted to do some maintenance on it to prevent future issues, now it hardly starts when its warm. The starter sounds like it's spinning fast it just isn't turning over for a while. Any ideas what it could be? I didn't have this issue before, I'm hoping the seafoam treatment didn't damage a seal. To get it started initially I did crank it for a while and could have possibly damaged the starter I suppose. The battery is only a few months old


So here is what I did,

Gutted the cat
Replaced the 0² sensor and added a spacer
Seafoamed the engine letting the seafoam soak over night
Replaced the plugs and wires
