Those numbers will result in a lumpy idle and probably hard starts/misfires when really cold. It should be alright down in Florida though, by cold starts I mean below 0 F.
I imagine it will run just fine with everything else spec'd properly. Rebuild the pump will ensure it is as smooth as can be.
Power will be fine, if the engine starts on its own it will have decent power provided the pump is set up. It might be a touch smokey though.
