Hey guys,
About 3 moths ago my bros little friend crashed out 450 into a tree, the front wheel came off and the frame got bent really bad, so we bought a new frame and parts that needed replacment and put them all on a new frame. We worked 2 days straight on it and finally got it switched over. We started it and it doesn't stay started long, I think there is a choke/idle adjustment problem. but thats not the big problem, when we rode it down our street it stauled(sp?) and i couldn't get it to start. so we pushed it back home and as we were pushing it gas was comming out of the bottom of the carb pretty steadly. It is commig out of the little nipple thing pointing straight down out of the bottom of the carb. I don't think we are missing a hose or anything? If you have any idea what this could be, please post!
Thanks guys

 

It sounds like the fuel mixture screw is loose but no positive can you get a picture of it.
Have you jetted this carb? If you have the screw could have come loose and gase would leak out of there.
