Carb question - '01 Xplorer 400 4x4
I noticed the other day that I was leaking fuel while it was parked and not running. After some investigating I found the source. There's a vent tub that comes out of the bottom of the carb. Is that supposed to connect to something? Or is it just a vent tub? This is the first time I've noticed fuel coming out of it. What can I do to stop the fuel from draining out?
Thanks.
Thanks.

well if its like mine its the vent line that comes out of the bowl and somewhere else(cant remeber right now, brain fart sorry) well im gonna asume its gas comin from the float bowl so it sounds like your floats are out of wack or something along those lines. pull the float bowl off and check it out and let us know what u find

Well, I got the problem resolved last weekend. I had it sitting outside to drain what little gas was left in the float bowl (with the fuel shut off) when a friend of mine who is a very good mechanic stopped by and I was explaining the problem to him and he suggested cleaning the air filter and the pre-filter because the pre-filter was pretty dirty (my fault for not cleaning it sooner) and possibly not allowing enough air into the carb. So I made sure the air filter was still in good shape, which it was, and I thoroughly cleaned the pre-filter and put everything back together. Once I fired it up, it ran like a champ. I drove it for awhile and then let it sit in my driveway to see if any gas was coming out of the carb, and there was nothing and there hasn't been since.
Another lesson learned.
Thanks everyone for the suggestions.

fuel is leaking past your needle and seat (the one attached to the float and allows fuel to enter your carb bowl) causing your bowl to overflow thru the drain tube
could be a bit dirty or sticky
it is good to clean the air filter,,sure,,,but not really going to help a fuel leak

Just because A follows B...doesnt mean A causes B.
Jiggling things around, and draining the float bowl, probably flushed out the piece of crud, that was holding the float valve open.
You should get into the habit of shutting the fuel valve to off, when the motor isnt running. Lots of motors have been wrecked, when the gas keeps flowing, but instead of going out the over flow tube, it goes down the intake, past the valves and washes the lube off the cylinder walls and piston rings. Its amazing how fast a motor can get trashed when the cylinder to rings, lubrication is gone.

your oil may smell like gas if this is happening

Hmmmm.......I never thought of that. Good point. Come to think of it, when taking the air filter and air filter box apart, I did take the top off the carb which also could have (possibly) removed some crap in there. I'll keep an eye on it, shut my fuel off, and if it happens again I'll change out the needle valve and seat.
