Our simplest and smallest piston engine, this kit builds a piston-ported 2-stroke. It is most similar to a Stihl Chainsaw engine. Designed to be used as a visual aid to explain 2-stroke scavenging, this engine is also a good way to see if you like building a Morris Models kit without the heavy investment that some of the more complex models require. This model is 8.5 by 4 inches wide when complete, and has about 30 parts. It has a 1.75 inch bore and a 1.5 inch stroke. This is rated for technically minded builders ages 12 and up with competent adult supervision. Expected build time is about 1/2 to 3 hours.
