Inside your Rotax 2 Cycle Engine
The series of  2 cycle  engines from Rotax were ubiquitous back in the 1980s for powering ultralights and light aircraft. These include the  582 and 503 models as well as others. There are quite a few still in operation today. While some models are not sold anymore, parts are readily available from Rotax and they are continually being rebuilt
