Tune it like a regular vintage saw, it should 4 stroke out of the cut and clean up at WOT. They need to be tuned while working or you will be way lean.
The myth that gear-drives rev slow is a hang over from the early 1950s.
Get your mitts on a late 60s or early '70s McCulloch or Homelite, they rev pretty good and have a feel of power you will not get with any other saw. The 87cc Mac 660 can buck 8 foot logs all day long and you won't get drowsy doing it. The 6-7 cube models pull heavy chain on a 72" bar with little effort.
Keep in mind that a gear-drive will continue cutting in a bind long after a direct-drive would have stalled, often resulting with the saw walking out of the kerf, with surprising speed and force. Never have any part of your body in line with a chainsaw, any chainsaw, however a hit from a 40+ pound alloy torpedo can cause considerable damage. We aren't talking about mere cuts here, shattered bones and internal injuries can result.
Yep. Tune it so it four strokes at WOT out of the cut and just cleans up when loaded down in the cut. With a powerful gear drive, you may not be able to load it down enough to clean up unless you're cutting some bigger wood.
