I've recently discovered a hose leaking coming off the back of the carbuerator of my '96 Yamaha Kodiak 400. The hose looks like it popped loose from somewhere, but I can't find a place to plug it back in. The hose is connected to the back of the carb and is about 9 inches long. It has a white tip extending out of it (like it is suppose to plug in somewhere). I was just riding, then stopped and shut it off for a bit and noticed the gas coming out. The bike then would not crank back up. After looking a while in vain I finally just kept turning over the motor and it cranked up. The gas seemed to stop after that ??? But I'm afraid it will start again and send my butt up in flames!!! Any hints?

Thanks,

i am trying to find out why my kodiak wont start, and i noticed that hose too. where does it go plugged in at. Kmoore does everything sound normal when you start it, but it just wont start. that is what is happening to mine. ant help?

 

Does the hose come to a larger rubber connector,and then turn into the white plastic tip? if so,it is probably your overflow hose,it may have come loose from the carb,the gas you are seeing is more than likely from the over flow,either your needle and seat is shot or dirty,and over flowing the bowl,which would make it flooded and hard to start,or maybe your float adjustment got knocked out of whack. I have the same white tipped connector off the overflow on my Wolverine,but the hose is a lot longer,comes out by the rear end. Hope this is some help to you.

 

The hose that you guys are referring to does not connect to anything. It is the vent hose for the carburetor float bowl. The white "thing" is a filter to keep mud from entering the hose. The filter was part of an update from Yamaha around then and you will notice some machines that do not have this.

Gas should not be coming FROM this hose because it has vacuum, not the other way around. Are you sure it wasn't the other hose at the bottom of the carb. that was leaking fuel?? If so, the vent hose could have blockage causing too much gas to enter the float bowl, a bad float needle and seat, OR a simple one time "flooding" of the carburetor.[It happens]

A flooding can cause the vent hose to leak fuel only if the engine is not running. There is no way the engine would run with gas coming from the vent hose.

Double check to see if the hose on the upper half of the carburetor is in fact the one leaking fuel. It should be the lower hose.

By the way, both of these hoses connect to nothing and simply hang down close to the swingarm and are very close together.

 

is that why mine wont start? i went through some water a while ago could that have got in the hose or something?

 

Nick,

The cycle finally started. It seemed it was flooded and probably the float hung causing the leakage. According to some of the responses (Thanks all!), everything sounds ok. Just a sticking of the float or something.

 

Nick,

Also, what we did to get it to crank was turn off the gas, because it was leaking out the tube. Turned the starter until it finally cranked. Then I turned back on the gas. After it was running, the leak eventually stopped. So far, so good.

Thanks again to the responses!

I have a 00 Kodiak and had the same problem awhile back and it ended up being the needle and seat and we had to replace the choke spring also. It does sound like the hose your talking about is your overfill. After I got mine fixed it was back to it's usual self and still running like a champ!!!!! Good Luck!![img]i/expressions/face-icon-small-wink.gif[/img]

 

thanks you guys for the info. i am just glad that that hose didnt go into something.
