RE: 3W-75 Engine
Now put a Zenoah, converted or not, in a 33%...
My ZDZ 80 DOES turn a Mejzlik 26x10 at 6700-6800 and powers my 24.2 lbs Extra very necely.
The full 1 Hp more on the ZDZ versus the 3W may be stupid things but what is not stupid is that the ZDZ IS more powerful than the lower displacement 3W 75.
