I like the 372's
, one of my favorite firewooding saws, that and a 346.
55's are great little saws, I've had the closed and open port versions, good cutting.
The big difference in the 55/346 is the top cover clips, better intake mounting to the cylinder(there's a nice fix for this), and the front tensioner, and about half a hp(although the 55 has a wide power band). A cheap upgrade would be to get into a 351(like the 346 oe) or a 353(like the 346ne although there was one without the primer bulb and one with
), then you could grab a cylinder from Spike for under $100, you can change a piston and cylinder right
.
I actually enjoy running the 353's, nice power and the wide power band means they are easier to keep the rpms up with a longer bar, which makes them cut quite close to a 346.
