Well, Taco, one of the biggest names in vintage mini bikes used a lot of West Bend 2-strokes. Ranging from their 95cc 580 all the way to 134cc 820 from the factory. The Sachs 340 was found on Rokon's, not really a mini bike or mini anything, they're ginormous 2-wheel drive trail monsters. Bonanza had the Hodaka which I believe was 100cc and there was the Desert Fox which had a Tecumseh 817MB which is 133cc. Even Lil Indian had the option for a Power products AH61which was 100cc.
