I'm looking for someone who may have knowledge on the working and testing of a Polaris RMK 600 Fuel pump. The machine starts fine but when you rev the engine it starts to falter, sometimes catches and then revs up. I have gone through the carbs and they are clean an seem to be set up properly. So I am turning my attention to the fuel pump. How does it work? what should I look for to see if it is working properly? Is it inspect-able? Thanks for any insights!
 
Fuel pumps on 2 stroke move fuel from the compression vacuum on the motor by pulsing the diaphragm in the fuel pump.
 
if the fuel bowls are full its not the pump , try again
