Thumbs up

My 2000 AC 500cc 4x4 automatic's Keihin carburetor is leaking gas out of the bottom of the carb and it will not stop. Engine runs fine. What can cause this? What are the possible solutions?

I shut the fuel supply off using the factory shut off valve but it continued to leak. Valve apparently does not shut off completely so I disconected supply line from carb and raised above the fuel tank.

Where can I purchase needed parts or new carb if needed.

I read a post that indicated this problem can be caused by trailering w/o shutting off the fuel supply. I must admit I did that today. How can this cause the problem? It has not been an issue before and I have owned it since new and trailered it many times with fuel shut off valve on.

I would remove the carb and clean it look at the float and float needle in particular. You may get away with removing the bowl and checking but I find it best to bite the bullet and remove it all. Not sure what the temperature is where you ride/trailer but a similar thing happened to me it was a little water in the gas that froze in the carb. I ran gas line de icer through it and gave it a few taps with a screwdriver while it was running without removing the carb and the issue went away. As others on here will say run a little sea foam through it.

There is no reason an 700 pound machine shouldn't catwalk and drive through 6 feet of water.

You need to replace the float valve assembly. The float needle has a rubber tip that gets worn and won't seal against the seat.

Thanks for the advice. I plan to try tapping on it this week end which is as soon as I can spare some time to get it inside and warmed up. Already added the Sea Foam-Wonderfull stuff. Hope the tapping works or l will bite the bullet and take it apart. I got my answer about the trailering. Apparently the bumping up and down on the trailer takes the floats to the max up and down and sometimes it just gets stuck down and will not release up to shut off the gas from the line so it just keeps flowing out the overflow tube. Shutting the supply line off seems to prevent this. Glad I found this site. Lots of nice folks on here.

your carb should have a bowl drain and a place to add hose to route outside motor - use it
you say leaking out the bottom -where
If your tank shutoff is not working replace it as I have seen leaking gas get into oil -look at your oil sight window -if looks milky ya got gas in oil -for transport or long term storage it must by shut off.
do not remove bowl in machine as in some units parts may fall out on some types of carbs and ya can not get back in with out total carb remove
