I purchased my XX used so I don't know if there is supose to be a handle to control the fuel valve. I can see the valve under the tank but it seems way back in there and not easy to get to. Am I missing some linkage? All I can see is a small square drive on the valve. Is there 3 positions? Is there a reserve? Also, I removed the seat looking for the tool pouch/owners manual and didn't see it. Does anyone know where to look for it? The owners manual would definitely help. Thanks.
