Building a two-stroke engine to Dave Parkes design: David Earnshaw and 'George' build I/C engines

摘要

Back in 2009/2010 Dave Parkes published a series of articles in Model Engineer about building small two stroke engines. At about the same time a student of mine in an evening class was looking for a design for a simple two stroke engine to build. What follows is a review of the progress made and some insight into building an engine to the Dave Parkes design. There are no photos of the construction of the engine as it was not until the engine was near completion that it was decided to write these notes. However, some photos of the complete engine are available. Photograph 1 shows a completed engine.
