Chainsaw Repair

Going back to Figure5, which is also for no tuned intake or exhaust, take a look at the smallest case volume (which is still pretty large at 2.44).  Not only is the rpm of max delivery ratio moved up, but it does not fall off as fast as for larger case volumes.  The peak is wider and flatter.

It is really hard to tell extrapolate this data to the the little engines used in saws at 10,000rpm with no pipes.
