Fuel spilling out of lower carb bowl vent - 2002 Suzuki VZ 800 Marauder

What is carbon vent? Never heard of it.

If you mean the carburetor vent at the carb's fuel bowl, the fuel level is probably too high in the carb. The top of carb will need taken off to set fuel level, unless there is an external screw for setting float level.

The fuel line connects to the fuel inlets towards the float bowl in the carb.Test the fuel lines to confirm the float valve seats are sealing.There are two Ts between the each set of two carbs, the lower is where fuel goes in, the upper is a vent.-------- Click this link below for more details with diagram:--- http://technoanswers.blogspot.com/2011/07/fuel-lines-routing-on-yamaha-xs1100.html ---------- This will help.Thanks.Helpmech.

There is only one fuel line that goes to the carb. Just get some fuel line and connect it from the gas tank to the carb. The other hose connections on the carb are vent lines, that go up over the top of the carb and the back down the other side and hang down lower than the carb. they vent the carb bowl

You might have water or dirt in your carb. Sometimes its the fuel can that is the problem. Your mower is new...but your gas can is old!

The first thing I would suggest doing is find the carb and remove the bowl located underneath it. Unplug spark plug for safety too!

Let a little fuel leak out of the carb with the bowl off to clean the fuel line coming into the carb. It may just a have a little dirt or rust blocking it. You can raise and lower the float on the carb to see if it moves freely and fuel stops and starts like it should, raising the float should stop flow an letting it hang down should start the flow.

If fuel flows freely then put the bowl back on, wipe up any spilled or pooled gas, and reconnect the spark plug. See if this clears things up.

If draining the carb bowl works you should go back and inspect the gas can and your mowers fuel tank for contamination. Chances are you have a layer of water down in the fuel tank and gas can. Empty the mowers gas back into the gas can and dispose of this fuel at a gas station that recycles waste fuel and oil. I would also suggest buying a nice new gas can if you old one is rusty, cracked or missing the proper vent caps that keep gas from getting all loaded up with moisture and dirt.

Good luck and be careful!

There is verfy possibly a fuel restiction in the carb. Many times the particles in the carb float bowl are restricting the fuel flow past the needle valve. I would advise adding some carb cleaner to your gasoline. The other possibility could be a loose carb or carb gasket which would cause a loss of suction through the carb and this would decrease the fuel draw. Soooo if the carb float bowl is the suspect. FIRST you will need to turn off the fuel supply. If no valve is avail, find a bolt or some object that will work to plug the fuel hose when it is removed from the carb you will need to grab a small bowl to catch the fuel when you remove the bolt holding the float bowl. Carefully and I mean gently remove the bowl (sometimes the bowl is slightly sticking and needs a slight bump)and see that the operation of the float moves up and down with no restriction of movement. See if there is any dirt in the bowl. wipe the bowl inside to remove dirt. Carefully reassemble. MAKE SURE no fuel is leaking or spills are in the area. Fire on the outside of the engine is not the prefered method!!!.
