Why Moki? I recommend the BME.

Gas is much cleaner, and provides the thrust needed....I'd be interested in knowing how many of the folks that are recommending the Moki have actually tried gas themselves, esp. the BME 50.

My experience with the BME shows that it is a fantastic motor, burns much less fuel than the Moki, the fuel is much cheaper than methanol-based mixes, gas burns cleaner so relatively no cleanup is required, and the gas is the same stuff you put in the car.

Ask for reasons, not just recommendations, and also ask for the recommdners experience with the other alternative, and you might get a different story.
