I have an 05 Yamaha Wolverine and earlier in the winter I found that the float needle was sticking open and gas would run out the overflow tube. I removed the carb, pulled the float bowl apart and cleaned the whole assembly. I reinstalled everything and the it worked great for about 2 months. I recently took it out ice fishing with not a problem, but after I returned home and parked it for 2 weeks I went to start it and gas started running again. I repeated the same procedure and its good again. Could there be condensation in the fuel tank from the cold and be causing the fuel to get messed up? Would adding an inline filter do anything as far as helping? I am getting good at taking this thing apart but would rather not do it again.
