Okay guys, I've got another question. Does Armor-All work in gasoline as a defoaming agent, like it does in glow fuel? I was running one of my 21cc conversion engines today, and I noticed that after the fuel got down below half a tank or so, it would get bubbles in the fuel line, and cause the engine to surge. I put foam around the tank and it helped somewhat, but a little anti-foaming "potion" would probably help too.
