" I just replaced all gaskets

" I just replaced all gaskets floats and seals on my 150 hp johnson 1989, I adjusted the floats after Joes advice but when I started the motor the carbs began leaking when I primed and cranked,It started with a couple of backfires and ran rough but stopped leaking when it was running.When I stopped the motor gas seaps out the troats and out the top middle vent holes. Whats causing this?
Please help, im pulling my hair out!

Thanks "

"Ralphy... did you ever figure this out ? My 90 EVRINRUDE does the same damn thing. the vro was bypassed by someone else and they put a elect fuel pump at the tank to deliver gas.. I think its pushing too much gas.. it smokes and runs like hell at idle. @ wide open, no prob.. please forward anything helpful to [email protected]

Thanks !"
 
The 90 VRO can be used as a f

The 90 VRO can be used as a fuel pump only or it is an easy conversion to the older pump( pre 84 ) the spot to mount the older pump will be on the manifold.
