Does alcohol make more power than gas?
The point is that the use of alcohol will not only mandate fuel system changes, but it will also mandate a different setup than gasoline. So, just why does alcohol make more power than gasoline if it has less energy per pound than gasoline? With methanol and ethanol it’s about 40 percent more than gasoline.
How do you convert an engine to run on alcohol?

Can a 2 stroke run on alcohol?

Is ethanol bad for carbureted engines?
Many of the critical components of a carburetor, such as the main body and float bowls, are die-cast from aluminum or zinc. When these materials are exposed to ethanol or the water often contained within ethanol, it creates a corrosive combination that can lead to carburetor malfunction and potential failure.
Is premium gas better for carburetors?

How does a carburetor affect the fuel curve?
The innovative carburetor design offers incredibly clean operation and cold start ability. This is NOT a simple vacuum port that hooks up to the intake manifold vacuum.
