Quadzilla 400cc quad need help.

[Quadzilla400]

So i brought a quad the other day a 400cc quadzilla, the quad seemed fine but i have a problem when i come to a stop it turns off or if im just in idle it will turn off after a few seconds.. i have read online that you can "idle ajust" the quad so it does not turn off when in idle i think this is the problem, it also smells like petrol. Its usually a screw or something that you ajust on most quads. Does anyone know how to ajust the idle on a quadzilla? Any help would be appreciated. Thanks i will post some pictures if needed

It might just be that the idle screw needs adjusting or it could be the idle jet in the carburettor is blocked. Have a look on YouTube to see how to remove, strip and clean the carb (not a difficult job) then search on there for adjustment.

From your pictures, it looks as though removing the seat and plastic side panels will make access much easier.

With it being Chinese, go and buy a length of vacuum hose and replace every vacuum pipe you can see on the quad,just as a matter of course.
From memory with old motocross bikes, it's the idle mixture screw you need to adjust, not the idle 'speed'. Turn idle mixture screw all the way in clockwise(turn gently, especially when it's about fully in) then back it back out one and a half turns, that's a basic position for most bikes, quad carbs.
Then see how it idles, if it seems fine bash on, if not just very slightly turn screw a quarter of a turn at a time either in or out, see which way makes it better, each time wait for the engine to respond to you're quarter turn.
