I've got a 2003 Skandic wide track. Has spark, mostly full tank of gas. No fire when turning over, with or without choke. Pulled plugs smell of gas but aren't dripping wet. Problem started with low fuel in tank. It fired but wouldn't run very long before dying, then wouldn't start at all. I filled the tank with fuel and a shot of IsoHeat, but it doesn't seem as though fuel is getting to the carbs and engine. Also pulled the muffler to check for built up fuel like my '86 Skandic gets when it is flooded. Nothing there either. Would appreciate any feedback with this challenge.
