There are computer simulators for flying real airplanes, model airplanes, race cars, boats, football, baseball, etc
Now there is one for Dolmar Chainsaws. In the future, perhaps, they will be even more sophisticated? We can go in and use different chains, sprockets, porting, compression ratio, muffler mod, and see what the improvements in the cut will be?
