Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I here you can make more power by adjusting the RPM higher. These engines are both 318 cc. Is the RPM set higher on a HMSK100? I here a lot about Hmsk100 throwing rods much more so than a Hmsk80. I want more power and have a chance to get a new Hmsk100. There is nothing wrong with my hmsk80 except it is 17 years old. Should I risk it? Is there and real benefit with a 10 hp unit vrs 8 ? Or should I just sell my old unit and buy a new one with more HP.
