Re: Clogged gas tank vent?
The vent? I take it off the tank and blow air up it if I can't do it from the outside, but most I did had the little chrome thing outside the boat. Or you can blow into the hose if you have to, make sure you take the gas cap off so you don't pressurize the tank.
They can starve the motor of fuel. You run it for a while and if you take the cap loose it might suck air in. If you leave the cap loose it runs fine, be careful of spilling fuel. You might run it and see the filler hose flatten, depending on how hard it is.
