Somebody's talking crap here & it ain't the tree!
The way you did that tree Wes is indeed in the textbooks. I'd say you just left too much wood for your backcut which is why it pulled a bit.
I have been told here however to not come in at a downward angle to "trip" the backstrap. I know if you'd have come in lower than the borecut you'd have been digging dirt in that video but I always come in below the borecut horizontally - less chance of grabbing your bar as the tree goes over and taking your saw with it.
Remember though that different tree species behave differently so what you did there may very well be a tried and true way of felling such a tree in that area. I wouldn't do it like that on any heavy hardwood leaners here that's for sure.
Also that 385 sounds like it's about to disintegrate and even through the computer that screaming cracked windows. There are nice sounding Huskies, and then there are Huskies that sound like they are within an inch of their life
Did Brad build that with 4 ports or did you add a couple to pimp it? You'll also find it will have more torque and bog less if you richen it up. Been there done it sadly...
It certainly was on the lean side. However, you can hear it 4-stroke at least 3 times as I make the face cut. That thing was at where it cut the best right there. A bit on the lean side, tons of torque and HP. The reason it was binding in the cut was the tree was leaning and perhaps most importantly, I made that cut with a chain I had set up for douglas fir - and it still sliced right through that Beech. That same chain on the 365 is a non-starter in Beech. In fact, the 365 cuts better with the full comp semi chisel chain I have on it than that chain in the vid. Even so, I generally run it richer. Well, RAN it richer. I recently sold her to an Irishman for the equivalent of nearly $900. I am sticking with ported 70cc's here on out for most my work.
That saw arrived on Brad's doorstep with 4 ports. He said something to the point of it just taking more and more fuel as he richened it up. I think it made a big difference in breathing:
Remm remm!!!
It might sound a little bad, but it feels very good!

Wes what poor victim, sorry, customer did you find for that 385 ?! Im with Matt and Ive never liked that cut since if you judge it wrong as Matt said you can pinch or get a flung saw, I did a big leaning Beech last Friday with my 390 and decided that a fairly traditional cut was in order as it was over to the left and above a smaller Beech sitting on a rotten root plate, Wes or anyone else if you want to post the vid up feel free, TreeworkDK, and you will see how close it was to 'chairing but I was aware and ready to go. Beech are funny trees if they are up straight you can do a fair bit with them but any pronounced lean and they just don't have the fiberous wood to allow to much steerage or hold.
The 390 had a great echo on the hillside where I was working which made up for my less than perfect work !

Wyk, please don't take this wrong, but I'm afraid that top end isn't going to last long. You're definately too lean. The only time it 4-stroked at all were the face cut when it was warming up. The way it sounds funny coming back down to idle after the bucking cut is a sure sign that it's too lean. The last video I watched of this saw was too lean as well. I'd hate to see you burn up a ringer of a saw. Hope in not insulting you here. Just trying to watch out for you.
No updates on my 390. I haven't had time to mess with it.

Yeah, you gotta' stop letting intruders take up your time. :msp_wink:
I will say it again though, that 390 sounds fantastic, especially in person.

Not to be an instructor or anything, but if you would have just "walked out the back" when you were bored in, you would have been safer, the tree wouldn't have been damaged and it would have been faster too with less effort. Here is a video on a tree with more lean.
Match your cuts up and you get a super clean stump, without a lot of multiple attacks on it at all angles, and then cleaning it up afterwards.

Not a problem, mang. I know it was lean. And I hope ya don't take this wrong, but she's in Northern Ireland right now in someone elses hands. I've finished porting the 365 for a second time, and I think it will pull that chain I had on the 385 with no problem now. Back when I was doin large firs, the 385 came in handy. But I am sold on ported 70cc's now.
Here's Dave's vid, btw:

That Beech is quite a bit larger than the one I took down. That one was mebbe 24" on the stump in my vid. Damn that 390 sounds great, David! Run, Dave, RUN! Nice bar, btw.

Excellent. I'll give that a try sometime, too. Thanks for the help, guys!

The cutter in the video is quoted at the end as saying:
"Thats what you get when you get a heavy lean on a big beech."
Are these the people that are teaching you to cut trees?? How do they not get killed or damaged saws, not to mention the damaged butt logs. That is really bad, they might want to chech into more safe and productive techniques, but that isn't working, sorry.

The bore cut gets a bad rap, not sure why, if you look at other techniques for getting leaners or high quality wood on the ground in typically requires several "attacks" or "chasing the cut" and other such weirdness.
The bore cut is quite simple, I think its hard for people to first learn due to cutting with the top of the bar. Like how you started your "bore cut" by flipping the saw over and using the bottom to get it started, that takes more time. Where as, with how I cut my tree and how I would have cut your tree it would have been 3 cuts max. Two cuts for the notch and then bore in and walk out the back.
Just something to think about.
There are a bunch of videos of different cuts starting at post #545.

Sam if you had read my post you would already had a bit more info about that tree and I had already said that it was far from perfect !
What you don't know is when I put the face cut in I found that at least 60/70 percent of the stem was decayed( in fact we were lucky it only extended some 6' up the stem) so I had little option but to proceed with a fairly straight forward back cut since it had a heavy lean over and to the left over the tree in the forground so I decided to get as much out of the hinge as possible.
In the vid you would notice that I move a few seconds before the tree falls because I knew full well what was about to happen. The prime objective was to get the tree down with the minimum of damage to the other tree.
Sometimes you have to work with what you find and it is not always pretty or if you don't have your wits about and weighed up your options it can be dangerous. I had made a call that the tree had far more problems than expected i.e. the decay in the heart of the stem and with 18 plus years at the game did what I considered best and if the root plate had not been so damaged it would not have looked so dramatic The lifted root plate was the reason the tree was being felled.
Had I not found the decay I would have used a bore cut as you should with a leaner !

At the risk of hi-jacking Brads thread even more so, I am now cured of my foreign addictions. I shall once again be a citizen of Texas at the end of this month. I will first be moving to San Antonio for a bit, then likely do some repair work on a bud's house up in Tulsa for a spell before I return to Corsicana, TX to help set up an Oncology Clinic(if things go well, I do radio therapy installations on the side, ya see). I do miss me some good TX Q! God bless Texas.
I thought Ireland was a permanent move for you?
Oh, I have Irish residency, but I am not a citizen. That's just too much of a pain. So I can come and go in Ireland as I wish, but since I am not a citizen, I require a work visa to remain in the rest of the EU. Don't get me wrong, tho, I absolutely love Ireland. It is one of the most beautiful places in the world, and my favorite place to live outside of the US. But right now I have better opportunities in Texas. And I got to admit, Texas is in the blood. I lived in Oregon when I joined this site, so not many here know that I am originally from Texas except for the few Texans I've chatted with. Texas is home, mang.

I saw some of your videos before, but they now I can't view them, it says they're private. I saw trees felling the at you, jumping off the stump to early and you running under felling trees. Just curious why you made them private?
