did you fill up recently, water in the gas?
Just re-read your post you did fill up, how much gas was in it before hand?
I and many boaters ran into this 2 years back after filling up for the first time in the season, basically had to burn the whole tank and fill up fresh, something with the mix of the 2 gases. The gas that was in it when I filled it was non-ethanol, and the gas I put in had the ethanol. I think thats what I determined to cause it.
But it would spit and pop, no power and I changed everything, plugs, filters ect and none of it fixed it. After burning it all I refilled and was fine.
Also not sure if when your state started using or even uses ethanol in their gas but the ethanol in the gas mixes with water easier, so for instance If you had a tank of gas before they used ethanol in it the water would not mix at all the gas (if you had water in your tank) and it would sit at the bottom and you would never know it. Put a tank of gas with ethanol in it and the water mixes more so with this bringing that water into the flow of gas...Just a thought
