|ENA Motor 1cc Version II|
This example is equipped with a spring starter, the users manual and the box which it came from as purchased new.
All models of the Jena line of model engines are sold in boxes resembling the one pictured below.
It is very difficult to acquire a perfect example of this rare engine; even the one from my collection has some nasty looking scuff marks on the rear crank case cover.
Below are shown the other Jena engines in my collection.
This story is about the rebuild of my friend Jose's engine that on inspection has a lot of problems: a broken crank shaft at the output shaft; excessive play; piston not moving freely and poor compression.
Below is shown on top my running engine and below Jose's rebuild basket case.
