John Deere L110 gas flow problem. The won't start this year. It cranks fine. I checked the inline fuel filter and it is completely dry. I disconected the in line gas line. The tube is also dry. There is gas in the tank. It is gas left from last fall. I didn't get in help from the manual. It doesn't appear very easy to get to where the gas in connects to the fuel tank (It's all enclosed by the mower housing) Can anyone point me in the right direction to resolve this issue? Thanks, LryRob
