can anyone help me to establish why my carborator pours fuel out of the overflow hose while I am wheelie-ing. I understand that it should leak a little but nowhere near what it does.
Thank you [smiley=Confused.gif] [smiley=Confused.gif]
Mine did that too,,,,,but I stood it on the back end to clean under it one time.
dunno.

dreth, I seen you ride. you are lucky thats all its doing. but if it had not done it before. I guest, I will check the float level of correct height and the needle valve for damage.
this is matt;shawn's computer is still broke we are riding tomorrow how can you tell where it should be
look at a service manual for your carb, it should say what it should be set to in there.
When you are check your float level. check the needle for wear or dirt on the pointed side.
thanks i took it apart cleaned it out and changed the main jet it was way to big it runs good now but still leaks on a wheelie but not as bad i did not see a way to adjust the float
you bend the bracket. measure the space from the top base to the top of the float that your float height. the bigger the space the less amount of fuel in the bowl. Good luck
did you change your jet setting before it started leaking fuel ? if so did you change the gasket on the bowl? If no, that maybe your leak. aslo went you check height on the float you hold the float up till the needle hits. Let me know what happens
Every 400ex and 300ex i have ever seen from off the show room to a beater has done this,your ot the only one with this problem if you wanna call it a problem
thanks everyone. this is my buddies quad we are trying to fix . it still leaks so he has wanted a new carb for a while now so this is a good excuse ;D . all the data did slow down the fuel leaking issue some so maybe its natural
ya, i leak fuel out when i do a wheelie or stand it up on end, but if u are standing it up on end to clean it or somthin like that then u should turn the gas off so only the gas in the float bowl can leak out ;)

if your running "pump" gas .... it won't matter ...
But Like BIG-DADDY Say's ... "float-level" ...
bend the tab up a bit .... but ... it will still leak some
