The Kart is constantly moving through the rev range so acceleration is key. The chainsaw needs to hit the power-band and keep there so the acceleration up to the power-band is less important and is probably only important for snedding or similar. The inlet port should not be overly polished as some turbulence in this area is good to mix the fuel and air. In fact many manufacturers put dimples on their inlet manifolds.

The chainsaw really needs the ability to hold the revs in the cut and under load rather than have better acceleration up to that point although a modified saw will often achieve this!

And there speaks the sense of it !  Was hoping you would come along Steve

Once saw a 372 without two fins - the bearing behind it was buggered because of the imbalance in the flywheel!!! There is always a better way.
