Help. 2007, never any trouble. Stored at dealer since the fall, pulled out, won't start. Ran perfect in the fall. Got a few pops out of it, no start. Drained carb, new gas, checked muffler and air filter for clogs/or issues. New plug. Plug does spark. Checked valves, .004,.005,.010,.011. Dissconnected kill switch. Put gas in plug hole, put gas down carb, no go. I am getting stumped! Maybe CDI spark not good enough? What am I missing! Any ideas would be GREAT!
