I use those pruning sawzall blades for a lot of stuff including 6x6 poles.

 

They are way better than you'd think definitely

I had to get some help cutting up a 30"+ diameter Cottonwood that fell in my yard. The tree guy brought an 120cc Stihl with a 41" bar and chain. It still had to work on the tree but did a good job. Now if I could just get the pieces moved around I'd be happy. That was one hell of a saw though.

So, I finally had an opportunity to use break in my 372XP Pro Clone saw last weekend to while processing ~1 cord of firewood.

It's jetted rich, which I left to help it break in on 40:1 Echo Red Armor.  I had to lower the idle a hair, but that was the only carb adjustment needed. 

It. berkeleying.  Rips.  After a few tanks my buddy and I did a head to head in an 20" log, and was easily 4 or 5 seconds faster thru the log than his Echo CS590 with a 24" bar.

Much smoother in the cut too than the Echo, which was my benchmark for a good saw.  Doesn't have the midrange torque of the Echo, but lots more on top.

As it cycled thru tanks, it seemed to pick up more power too.  Going to run it a few more tanks before I lean it out a hair, as you can tell it's just ever so slightly on the rich side.

I'm very, very happy with it.  Only thing I need to do is replace the fuel line - it's just a hair short and doesn't allow the filter to sit all the way down in the bottom of the tank, and you can't burn all the fuel out of the tank before seeing fuel starvation. 

It does seem to use a lot more fuel than the Echo.  How much of that is jetting is unknown.

The muffler mod on my saw is ridiculously loud but with a set of ear muffs is quite pleasant lol

i'm stoked to hear you love it! Ever since i saw this thread a few weeks back i have totally gone down the rabbit hole of chainsaw stuff. I've heard a lot of guys say that the clones pick up more power as they break in so you should gain some more as you run it. 

I've also heard that some of the non-pro 372 clones can have some casting flash and poor port quality, which to me means that when I get one it's basically required to open it up and give it a port job right away. there's a guy on YouTube who i like (shoutout Dyno Joe Mods) who did some relatively standard porting/squish cutting on a 372 clone and went from 5.35hp/3.58tq to 7.79hp/4.14tq which is nuts. that's getting pretty close to 90cc power from a 72cc saw
