im having problems with my quad flooding out. i have cleaned the carb,petcok, fuel lines then once its running i can take the vacume line off from the petcok to the carb and it runs 100 times better but as soon as i connect the hose it sucks gas and chokes out the bike can anyone help please.

Do you have your vacuum lines connected properly?

the small line going to fuel pump is connected to the plastic nipple on the carb, the line off the petcoc is going to the metal nipple on top of the carb

Are you saying that fuel is entering the vacuum hose when you hook it up? Sounds like you have a bad petcock. Since you say it runs fine without the vacuum line attatched, it seems like the easiest thing to do would be to install a manual fuel valve in place of the vacuum operated petcock, and block of the vacuum line. Or you could just get a new petcock, but they are expensive. I believe there are models of that machine in the same year that use a regular manual style petcock.

dirtdemon is right:biggrin:. i had this happen to me. the diaphragm breaks inside. just block off the vacuum line, you don't need it. the primary pump is good enough. or when your starting after adding new gas to an empty tank just blow into the tank a little.
