Carb squirting gas

[Scub@dud3]

I have a 1988 50 hp Force engine. It ran great but it would occasionally stall out when the boat would rock in heavy waves. I replaced the needle valve and made a minor adjustment to the float. Now the boat will not run and the carb is squirting gas from the side vent. did I drop something I am not aware. Any help is appreciated.

Needle valve and seat, and float level, control squirting from the side vent. Backtrack! Probably float level. Low fuel level may have caused the stall.

I concur with foodfisher. I have a 1996 force 50 I've been rebuilding and I had fuel squirting out of my air vent too. I replaced the needle, squirted carb cleaner through all the various holes/jets and adjusted my float. Problem solved for me. I have a feeling it's your float..

More than likely your float setting which should close off your fuel intake into the carbie, you mention replacing the needle but not the seat?
Personally I would take off the carbies, fully clean them, blow them with compressed air and adjust your float level to it's specific height.

Thank you for your input. The seat is pressed in so I left it. The carb has been cleaned very well, I have adjusted the float height stop 5-6 times. The fall stop on my float adj seems to be missing. I have set the float height (Lift) stop to factory specs, it works on the bench but not on the boat. I think its gotta be a float thing but what else can I do?
Thanx again for the input.

The best way to simulate fuel flow into the carb is to get a short piece of fuel hose attached to the inlet tube of the carb and slowly blow into the hose simulating fuel flow while with the other hand slowly raising the float. When the float reaches horizontal, you should experience resistance in blowing into the carb indicating the needle is closing the inlet port eventually stopping you from blowing into. And when the float goes down below horizontal it should start letting you to blow into the carb again.

The float "drop" isn't as important as the level.
On some carbs it's not adjustable
Yup make sure you take "all" the carbs off and clean them..
