David should know, he ran that saw for part of an afternoon last summer up at my place.

I ran a pile of your saws for a couple cuts each. My memory ain’t that good! What I have noticed is my 266s tend to lug well.

Small world.

I should add that I have everything but a PnC to build a 272…and I think they should be here in a couple days.

That was the saw you limbed and bucked up the fir with, and I seem to recall someone asking me if I remembered how a 6100 handled......

I’m old. I don’t think that fir was diametrous enough to test the limits of the mighty 272.

…and how could you forget the ported 6100? She bad! Especially in that cedar… :-D

Mebbe. I'll say this, with a 28" bar and a well set up chain it kicked ass and took names. I stopped running it with a 24" after the chain pinched while I was undercutting a snag with the top of the bar. The tank handle hit my hip joint pretty hard, and if it had been a little more to the left..... 'nuff said.

It has a 7 unless I'm playing at cookies. It's more of a RPM ripper (kevin built it for a cookie play saw for himself and then sold it to me). Outcut a 272 in speed yes, but I'm not looking for speed so much in a felling saw.

Why does speed keep a saw from being a felling saw?

I think we're referring to the high rpm power band, like its making power in the 9-12 area , where as its more comfortable to make notches with a saw in the 7-10 thousand area.

272 more torque than 372? I found the opposite to be true. The stroke of the 272 is 2mm shorter than the 372.

I am a firm believer that upper transfer roof angle plays a big role in a saw's manners. I am pretty sure a 372 oe could be made to out-yank a 272 off the line with the bar in the wood...especially given the stroke advantage that the 372 has....and as @Stump Shot already mentioned, the 572 probably is even better since it has an even longer stroke than the 372.

A little bird told me that side fed vs. bottom fed makes for more grunt.


@mettee it will probably be a few days, but I intend to do some testing and explaining vids on felling vs. bucking. Not that I'm an expert...this is my learning process.

*another piece of the felling puzzle is physical size and fitness. I'm 6' 185lb, but I don't get as much exercise as I used to, and have issues with my left arm and shoulder which is the primary support arm for a saw...

OK, having felled with the 288 a bit now, I like it...but she's a mite heavy, at least for the size of stuff I've been cutting. The goal is light weight, grunt off idle, and longest bar for cc. Which after messing with my 266s and researching 372 vs 272 makes me think 272. A video by hotsaws101 and this quote by Holmen tree on AS stuck out to me.

"Yes the old edition 372XP is touchy in the wood. When I switched from the older Stihls (066 064 044) I found the 372 only had good power at WOT. Let off the throttle a bit in the cut while felling with the bar buried and the chain would seize with chips jammed in the bar rails. (I have experienced the chips in the rails plenty myself)
Keep the 372 rpm high and it was a laser in any size wood the 22" b/c could handle.

Interesting thing I noticed when a few years later when I bought a 272XP which is 13 years older then my 2006 372XP. The 272XP cylinder design didn't have the top end only high power capability. But more like the modern 372XP X Tork power with some grunt also on the lower midrange revs.

Ideally the older 272XP power band may be more user friendly with room to modify the porting and compression for more top end power, but in the end buying a new 372XP XT EPA regulations rules."

Now, I have an XS 2166, and I'm getting to splitting hairs here, but I wonder how it compares to a 272 with a least a BGD, MM, etc. I think the 2166 is a bit heavier and I prefer the KISS of the 272 vs. strato. I did some experimenting weighing saws and see what I can hold out sideways in front of me arms extended as if reaching and cleaning out a face or starting a cut, and 266 with a LW 24" is the limit of what I could do very much. I can get the 2166 28" out there but it would wear me out. Heck I did it with the 288 and 32" heavy stihl bar...

Damn your weak

Let's ask @Czed what he thinks. Oh wait, he started this...

old school is cool by me...

A ported 181/281/288 will walk all over
a ported 266/268/272
But at a cost in weight and fuel
It's meaningless now I'm the last one in my area running 2 series
I'm just a firewooder now.
The loggers are running 371/372/572/394/395s
Haven't seen a 592 yet
and other's the stihl equivalents 044/440/046/460/461/066/660/661s
The guy's that make money here with saws run somewhat modern saws.
Of what I own and there's no way I'm buying another platform of saws
I prefer the 266 first then the 268/272s
Ported of course
I can cut all day with these and not have an issue


Zoo city 272
If I ever lost my 25/35 whatever saws
I'd get a new 372xt or 385
Or echo 7310 or dan had those carbed 462s for the simplicity I don't need the baddest saw there is.
I don't care what anyone says about autotronic saws they are just not something else I want to get pissed about when a problem happens
I'm old and don't care if it's 5 year's later and it needs a dealer
I have 40.00 saws that are 30+ year's old that never failed.

A 930 Jonny super will give that 288 and the 064, a good run for their money.

I have a 920 it's neck and neck with my stock 288s

 

[sawfun]

I might like my Boost Port P50 better than my ported 390xp, maybe it's just an old guy thing. I prefer my ported 372 over either of those. The 390 just isn't that much better than my 372's to justify the weight.
