Take them off and clean them, it prob has gummed up fuel in it. The side hole are from the bowl over filling from the float either sticking or the needle is bad. when you take the bottom off try and blow through the fuek inlet while moving the float up, if you can't blow through it with the float up your needle is good. make sure your floats are good, i had a float with a pin hole in it and it would fill up with fuel and go out the over flow holes.
