I was plowing with my my quad last night and the thing just started sputtering and died. It will start and idle but if I put it in gear or try to give it gas while in neutral it stalls.
If I feather the gas it will rev but then winds down stalls and then pops.

I removed the carb and cleaned it, still doing it.
I drained the fuel and put new fuel with sea foam, still doing it.
I pulled the fuel line and started the engine and there is plenty of gas flowing out.
Maybe the electric choke? But I don't smell it flooding.

I guess I will try the plug next, but it doesn't seem like a plug issue, it's acting like a fuel thing. But the carb is super clean and the fuel is new.

Anyone have anything ideas?

 

Yeah! It was the plug. It was fouled. Not sure why, but at let its running now.
