Really? Cuz my source sez it has a 'heavy duty' centrifual clutch.
Anyway, here's a cool project for someone. Small Engine Warehouse has
new old stock Sachs 3.7 hp 2 strokes, $130. I'd love to see this
rare Batavus 3 whl. moped upgraded with the Sachs. The moped
is on craigslist , skagit/island, in Washington state. One version
actually used a Sachs.
