Leaking float bowl gasket

Fuel leaks from my float bowl when I tilt my 1994 &0HP Force up. The float and inlet needle seem to be set right as I can pump the primer bulb until lit gets very hard and not force any fuel to leak from around the bowl nor come out of the overflow weep hole. Not a lot appears to be leaking but enough that if I tilt the motor up and haul the boat to the lake I would imagine it would eventually leak into the cowling some. The bowl gasket is a new OEM one (looks like it is cork). Are these cork ones always going to let some fuel seem through them or do you think I have a another issue causing this other than a leaking gasket?

When fully tilted, it is normal for the carbs to leak fuel either from the bowl vent hole or even from the carb's throat. There's just no way to avoid this unless you decide to run the carb's bowl dry just before shutting her down.

Like Jiggz said they will leak some when tilted. Normal.
The gas will evaporate but the oil will find a way down and out.
The cork or fiber gaskets? Both about the same.
It's probably not leaking at the bowl but the throat of the carb.

Try not to run the carbs dry.
That can cause damage to the cylinders.
The top carb runs dry first. It will cause scoring in the cylinder.
Not the first time but over time.
If it's a problem get an absorbent pad and put it in the front of the lower cowl.

Thanks guys. I guess some is leaking out of the throat like mentioned although I can tell some is definitely leaking our of the bowl. It's more of a pet peeve than a real issue though. I was just hoping the bowl gasket could be replaced with a better gasket material to make it leak free and just have to worry about carb throat leakage.

Make sure you have a fiber gasket on the inside and outside of the fuel bowl where the bolt passes through. That is the bolt that holds the fuel bowl attached.

Make sure the cork gasket is seated evenly in the groove around the perimeter. If it looks distorted or uneven, it might not seal properly. The cork material usually works pretty good.

I know I have both of those gaskets on each side of the bowl. I will revisit the cork gasket to see if it is seated right. I could see how it could not be quite all in in one area and cause a high point of contact on the bowl.
