RE: Evolution 1.00 vs OS 91 FX
I vote for the Supre Tigre 90 against both of these as it is a stump puller and I have found the ST carb to be quite user freindly!!! The OS I had was a bear to adjust, needed a pump to run well and never quite lived up to the power they promised. Now maybe the 91FX and the old os 108 carb....hmmmm...that might be an idea......
