But assuming it's summer, then that doesn't sound right. But I'm anything but a fuel system expert. I understand the basic operation of a carburetor. But no details.

Could it be that you're running so rich that you're dampening the combustion?

And could a weak spark be so weak that it'll only support mild combustion?

I don't think this'll help much. But maybe it'll percolate some ideas.
It is probably more like 1 minute not 2 minutes. But the possibility of running rich could be right because I am running 16:1 because I wanted to use up 5L of 16:1 and not throw it out. I am on my last tank and after it runs out I will use some sort of synthetic oil like I mentioned before and go to 50:1.
