Re: 15hp johnson

I check gas two ways. By smell and by feel. If it smells like bad gas, it's bad gas. But bad gas can still smell fine. That's when I feel it. It should be cool on the fingers. If it's warm, it's bad. Evaporation cools. If it stays warm, it isn't evaporating. If it doesn't evaporate, it doesn't burn.
