I wonder, did the Germans come up with any brand of 2 stroke mower engine? Like the Japanese, our cousins in sausage shop land had a high regard for 2 strokes I believe. You'd think they of all nations would develop their own. I believe Deutschland was one of Victa's export markets. Maybe they saw the mower engines from Australia and thought "even we can't better this" and decided to concentrate their energies on other projects lol.
They did have the quirky Trabant car, albeit from communist East Germany. They turned out to be quite reliable, albeit rudimentary.
