I have an 05'Eiger 400. It has never given me a minutes trouble until this weekend. Rode it last weekend with no issues. Parked it in the garage and would crank later. It turns out that the filter box is full of fuel. The crankcase also is full of gas. I took the carb apart and cleaned everything (several times now). Got it to crank but it dies everytime you give it gas. I can keep it reved but then gas is starts pouring into air box. Took the petcock off and cleaned it. That helped a little but not much. At wits end...Help!!!!!
