Fair 'nuff.
Every chain saw I have ever used has been louder than $#@&, we live in a major city (Toronto, Ont) and they are already talking about banning trimmers. A chainsaw engine would never fly (no pun intended in this forum), way too loud, the Craftsman engine is just the right loudness.
I agree that the saw's will probably have more torque which would be useful, ie I would rather have a "tugboat" engine than a "motorcycle" engine.
Short stroke and big bore is perfect, but you gotta work with what is available.

Thanks Darren
