You could heat the fuel by wrapping tubing around the cylinder, creating a
cooling effect for the engine and preheating your fuel.

Hmm, so are non-Berkeley students allowed to help with the design and fabrication?

I'd say the B&S is rather crude when you are considering low fuel consumption.
We're talking about 250cc motors making 5HP with a F-Head design.  I'd expect
a weedeater or chainsaw engine would be a better approach.
