Hi guys was wondering if any of you would be able to help give me some advice, I have a bst40 carb on my 640, when I turn on the fuel it pisses out the headers ??

Bikes been an utter nightmare recently I'm one step away from lighting it on fire but at this rate it may do it for me ?

She won't start because of it an I imagine it's leaking passed the piston rings an into oil so I'll need to dump it an change it too but if any ideas that be great on why it would do this.

Cheers

Doug

Stuck float needle
Try tapping the side of the carb float bowl with a screwdriver handle

I dont know these bikes/carbs, but should fuel not be coming out of a breather pipe/s before it starts coming out anywhere else? So is a breather pipe/s blocked as well as the float valve?
