This was a “cutters edge” rescue saw in its first life. If your not familiar with them they are very expensive. It’s a Jonsered 2171, they put an 8 pin rim on, different bar and carbide “bullet chain”, heat shield, depth gauge, K&N filter, full wrap, D Handle starter and a scrench holder. This one was straight gassed early. I put a 372xp top end in, 20” total bar and RSC chain. Not much of a test but I have some small stuff to cut on my property and the locust was first. Very smooth, I’ll have it in some real wood soon
