fuel filling bottom cylinder

[gww]

I have a 2002 70 hp johnson bombardier 4 cylinder 4 stroke
that when the outside air tem is high it gets fuel in the bottom
cylinder after it sits for about an hour or so I have allready swoped
fuel injectors but the problem stayed on the bottom cylinder

That being a Suzuki engine you might do better posting on a Suzuki discussion board. My best guess would be that either some electronics are holding the injector open or there is some way for a fuel pump diaphragm problem to bleed fuel into the bottom cylinder.
