I think Tim touched on it briefly, but didn't elaborate. I bet the fuel line is too close to the engine and the possibility of an exhaust manifold leak is real. It wouldn't have to be a big one either, just blowing right at part of the fuel line.

When I got my 8N the previous owner had replaced a six inch section of the steel line with rubber from the tank to where it turns and goes down to the carb. I was running it in 100 degree weather and saw the gas bubbling in the tank, not a lot but enough to make me shudder. Then I felt around under it and saw just how hot it gets between the tank and the engine, even in normal conditions.

If you didn't to start with, get the 30 inch brake line and bend it where it is as far away from the engine as possible. I thought about designing some kind of heat shield, but haven't figured out how to make it work right.
