The Mini 2 Evo engine is well-established on the market. It is the winner of many international championships. Now upgraded with a new lighter muffler, and an air box, to make it even quieter and more attractive. 
 
The Mini 2 EVO is similar to the Simonini 250. They share some common parts, and have the same displacement, horsepower, and weight. The main difference is in the belt reduction pulleys, and their configuration for engine orientation. The Mini 2 EVO pulleys are configured to be inline with the crankshaft and cylinder, for an upright or inverted installation. The 250 pulleys are oriented to have the engine mounted horizontally, with the cylinder head to the left, so its offset weight will counteract torque-turning on powered parachutes.
