yes but there must be some assictors to the ethanol fuel or methanol so the fuel ignites on the right time so it does not damage the engine. Yes ethanol is a much better fuel, it has more then the double of the heat power of the gasoline, then let me tell you my friends there'san experience availiable on the net that shoes you a normal gasoline engine, monocilindrical motor, thats first runned on gasoline for about 1:58 s and had the hourse power of 1.3 HP( Hourse Power) and then it runned on ethanol and it had the power of 3.1 HP thats because ethanol is an oxygenate and it has a much more complete burn then gasoline and it has a oxygen atom on its molecule so it has a faster burn when compressed!

Yes, a lot of cars in Brazil run on 100% ethanol. All Brazilian fuel contains at least 24% ethanol, and much of it is 100% ethanol http://www.google.com.au/search?q=cache:NgPnLGAu9MYJ:journeytoforever.org/ethanol.html+100%25+ethanol&hl=en It's clean, produces a lot of energy and is friendlier to the environment than oil or gas. I don't know why all cars don't run on it (oil companies and their influence is the most likely answer)

There are many Flexible Fuel Vehicles out on the road right now and the drivers don't even know it. Any Gasoline car can run on E10 (10% ethanol 90% Gasoline) The flexible fuel rigs can run on E85.

its all about the carb and fuel system. you want to use a hotter plug, good compression like 10:1 or more. other than that use the green diaphrams "non rubber", twice the jet size, and the brass floats,on a holley with at least an 110gph 8-15psi pump. basicly you have to flow twice as much alcohol as gas onthe same set up. hope i helped at least a little, if not try calling barry grant.........

The engine "being built for methanol" is just that- an engine BUILT for methanol. Most engines built for gasoline will not run safely on pure alcohol, and may not run at all. The flow rate required for the alcohol is significantly higher than for gasoline, so some components may be too small, and the chemistry is such that some materials for a gasoline engine may deteriorate quickly in pure alcohol.

Methanol hates starting, especially in cold weather and usually requires a higher compression ratio.
