A couple of months ago I started my 2005 kodiak 450 to help me with cleaning snow out of my driveway. It was cold so I had to start it with the choke on. I was shoveling snow while it was warming up when I heard it start sputtering. I couldn’t make it back in time and it eventually fouled the plug and I couldn’t get it restarted. I tried for a while until it eventually backfired and I left it alone. I didn’t attempt to start it again for a couple of months. I replaced the spark plug, drained and replaced the fuel, but I still cant get it to start. It has spark and when I open the drain on the bottom of the carburetor fuel runs so I assume it is getting fuel. I even tried starter fluid and nothing!
