I second that!! In fact, glow fuel works just fine in spark ignition engines. if the carburettor is designed to meter glow fuel, it needs to be richer than gasoline.
Glow fuel however does have a higher flash point than gasoline does and so gasoline is a lot more hazardous than glow fuel. Gasoline will provide flamable vapors in temperatures as low a minus 40 degrees F. Methanol has a flash point of around 50 degrees F. At temperatures lower than that, it does not provide enough vapors to form a combustible mixture. That's why you see people prime full scale methanol burning race cars with gasoline before trying to start them. It's also why they sell E-85 instead of E-100 at the gas station. That 15 percent gasoline is there so engines will still start in cool weather.

Another advantage of gas models that no one has mentioned yet is that gas powered planes don't get as messy from exhaust residue. Most gas engines have needle bearings in the con rod and can run with fuel that's around 2% oil. Most glow fuel is around 18% oil and it mostly ends up on the plane's fusilage after it goes through the engine.
