I agree that it likes compression, but it is not absolutely needed. Totally runs cooler. Makes more torque, especially in smaller motors. Is definitely more forgiving in your tune up. Not necessarily more consistent, just doesn't move around as much with the weather.
The maintenance I totally disagree with. Although it can attack uncoated aluminum if you keep everything full there is no need to drain and lube everything like dak does. That's is not to say that what he is doing is wrong or bad just more work than I have needed to do.
Cheaper to run IMO.
Injected, he is right, a primer system is worth it's weight in gold. Carb cleaner does a fantastic job in place of a primer though on initial start up. My carburated motor starts without anything but alcohol down to about 40°.
dak, no offense intended on our disagreements. These are just my opinions of running alcohol for 25 years.
