This is the motor I rebuild while telling (approximately 4) anecdotes from my past. In the 40 minute show entitled "Le moteur à 4 Temps"That mean's "The 4 Stroke Motor"
It's a 634cc air cooled horizontally opposed 4 stoke twin from a Deux Deuches.
By the way, who can tell me why the Google search engine can't find this blog .
