Ok here it is someone help, I crank the kfx700 up with the fuel pump wires pluged in, it runs but pores gas out the bottom of the carbs then I unplug it and it still runs but no poring gas the 5 mins later it starts to cut out because it seems like it not geting enough gas then you plug it in till it starts poring gas then unplug it and it runs same thing plug in pores unplug runs spits and sputters then plug in again????????? whats the problem I've cleaned carbs and floats are not stuck

 

i dont have a kfx 700 but i did have a AC 650v that would do the same thing, it was in the shop 5 or 6 times . you may have a kinked off return line which makes the pressure billed up blowing bast the needle & seat. seams to me there is a service bulletin on it some were .
