The most popular powerplant for Avid Aircraft is 2 stroke Rotax 582 - more hours has been flown in Avids behind Rotax than any other engine. Most of them perform very well and there is very little incentive to change to other engine.
On the other hand, new engine options include Jabiru 2200, Rotax 912, Subaru, BMW and others offer more HP, 4 stroke reliability, better fuel efficiency, longer TBO and others. Whatever your engine choice you will spend more time on keeping it in top operating conditions than any other part of your airplane. Listed below are most popular options if you feel that your choice is not represented e-mail me mtschindler_at_yahoo.com.

Stratus 2000

Stratus Inc. converts the reliable and proven 1.8-liter Subaru EA-81 engine for use in light aircraft such as Avid Flyers and Cessna 150s. The converted engine incorporates a belt reduction drive engineered exclusively for Stratus Inc. A Stratus belt drive is quieter, smoother, and easier to inspect than a gear drive. It uses a 60-mm-wide HTD belt. The reduction drive's ratio of 2.2:1 reduces the propeller speed to 2,500 RPM, offering maximum propeller efficiency and quiet operation. All the components of the reduction drive meet aerospace standards. The drive's sprockets are hard-anodized for long service life. In addition to the reduction drive, Stratus engines are fitted with a lightweight custom intake manifold; dual, Bing altitude-compensating carburetors; and engine mounts that incorporate Lycoming motor mounts. The Stratus engine is zero-timed to factory specs, produces 100 horsepower, and has an estimated TBO of 1,000 hours. Compared to two-cycle engines, the Stratus engine offers more reliable and quieter operation. Compared to certified aircraft engines, the Stratus engine offers lower fuel consumption and the ability to use unleaded auto fuel. Both home builders and certified aircraft owners benefit from less engine vibration, resulting in a more comfortable ride and less fatigue on the airframe. They also benefit from an engine that's easier operate and easier and cheaper to maintain. Replacement parts are inexpensive and are available at most auto parts stores. Before they are delivered, Stratus engines are completely assembled and test-run. Each engine includes a reduction drive, electric starter, air filters, an ignition coil, a fuel pump, and your choice of prop extensions.

The above is from Stratus 2000 web site.
