Hi all,
I've had an Efco my8200 (80cc) for a little under a year, have done a lot of work with it, and am very happy with it overall.
However, I just picked up and fixed a Jonsered 920 (87cc). I put the two to a test, five times, of using an 18" bar (both had new bars) with Oregon ripping chain (both had new chains), and various diameter logs. I would have the two saws milling slabs off of the same canted log (at the same time! just kidding), so they were doing the exact same task.
And, I'm sure you're surprised based on the title of the thread, that the 920 destroyed the Efco. Not much of a competition. I do recognize that the 920's 7cc's bigger, but still, it was much more than a 9% milling speed increase.
What's going on here? Superior torque on the part of the 920 due to a heavier crank?
Thanks,
Bryan
