How old was it? It would have had to have lost a ton of octane to make a mower engine "diesel."

I hate wasting BTUs. Old gas goes in the tank a bit at a time. I also dispose of used solvents from the lab that way, after filtering through a paper towel. But I will not put acetone in the tank.

Over the years I've gotten rid of alcohol, pentane, kerosene, stove fuel, nitromethane, and mineral spirits.

What kind of percent of nitro did the tank end up being? Any spike in power for that tank?

Throw a match in it.

IIRC, it was about two years old.
