heres what game faqs says

Close all three valves here. Pull the lever to your left forward. This will
raise you up one level. Close three of the valves so the needle gets in the
red zone. Now pull the lever forward again, taking you to the top level. close
one of the valves, then pull the lever backward, taking you back to the second
level. Open one of the valves you previously closed. Pull the lever backward to
take you to the first level. Open the far left three valves (you cant turn the
right one, and don't need to), which should bring the needle right onto the red
line. Go to where the ladder on the left is, and turn the valve wheel there to
fill the airship.


THe needle doesn't move also says move lever forward and backward in there i move lever forward it doesn't stay so how am i suppose to move it back
