My bros friends crashed our 450 last summer. Earlier this summer we put all the woring parts on a new frame and bought new parts for the ones that were broken. Once we tried starting it started for a little then shut off. We tried adjusting stuff, nothing helped. After trying to start and start it, alot of fuel came out of the bottom of the carb, don't know why. Any Ideas on fixing this carb problem?
Thanks

 

typical yamaha junk carb. the floats are probably stuck. how old is this 450? i would send the carb off to be rebuilt if it is any older than 3 or 4 years.

 

its a 06. with only 800 miles on it. We cleaned it as good as we could when we put it back together...guess im going to have to reclean it with gasoline.
