NEO-TEC NS8105 42 inch Gas ChainSaw with Guide Bar Chain 2-Cycle Power Head 105cc Power Chain Saw 4.8KW 6.5HP Gasoline Chainsaws All Parts Compatible with G070 070 090

Great saw for milling and big removals. Just brake it in easy. I ran about 1 to three tanks at 1/2 power. After that, the saw ran for two days milling redwood logs. One thing I would recommend is to start the saw without using the decompression button(specifically when it warm) Starts easy, first pool. When I put the bar oil in for the first time it leaked a bit over night. However the next day the gasket sealed up and I also made sure the bolts were nice and tight. Overall no issues with the saw at all. I ran 42 inch bar on it.plenty of power. Just make sure your chain is sharp. So far happy with the saw. Worth the money for sure.

I bought this saw after moving onto a small piece of property with lots of large oaks. I knew that I would be dealing with down trees occasionally and would need a large saw. I simply don't run it enough to justify paying 3x the cost for a Stihl, so I rolled the dice with this one. I have cut a few large fallen trees (3-5 foot diameter, 1 fir and 2 large oak) and this thing eats them all without issue!! This saw is an absolute beast!!! Fair warning though... this is a heavy saw and is a workout to use! Also...make SURE you use the compression release when starting it!

Brand New out of the box and it took 3 days to finally get it to start. Once it started, it ran decently. I didn't like the sound but it seemed super sensitive to any bit of adjustment, so I left it where it started because it comes setup for running for the first three tanks of fuel. Annoying popping sound aside, it ran good and it cut like a dream, to be honest... made my other saws look like junk, including my Rancher. However, I spent the entire next day trying to start the saw on it's second tank of fuel with no success. The first pull was the only pull that sounded like it would start with the next pull; it never did. Brand New Bosch "Start" spark plug came in it but there's nothing in the User's Manual about the proper spark plug gap. Definitely getting a charge to the spark plug and I've repeatedly gone through the steps for a "wet" plug/flooded combustion chamber, but still will not crank. As wonderful as the saw was the one time it did run, I still cannot give it more than a single star. All of the hours and sweat lost trying to get the saw started completely negates how well it cuts big timber. If I can figure out the issue, then I'll update my rating and provide what I've learned.

As a former shop instructor I’ve had the privilege of seeing all manner of material removing tools cross my path. The saw arrived well packaged and assembly was surprisingly easy. A neighbor had recently taken down some old oaks so I asked for the large trunk sections with the idea of cutting some slabs with this 43” beast. It’s not a lightweight saw but once the cut was started the 90 degree position handle feature allowed me a very manageable fairly strait cut along the 8 foot trunk section. During the 40 minute assemble and test run it met all my metrics for a quality built and inspected machine without any glaring exceptions. IOW everything went together and nothing gave me the impression that it wouldn’t last long under usual private estate use. I’ll be experimenting with the tooth angles a bit when resharpening but the existing factory chain angles are already optimally set towards a balance of loading the engine without it getting caught in the cut (happened a few times in the slabbing operation) and needing to be freed up. Use the wedges and keep it oiled with proper bar oil and I’d wager you’ll prosper. In short, a worthy saw at an affordable price.

It's a beast!! Works awsome!! Had an oak tree fall with a 48 inch base cut it right up. Buy an extra chain, make sure it's the right one , first one I bought was wrong. Pros. Plenty of power, great price easy to start. Cons heavy... heavy... hard to hit off switch while wearing gloves but now I pull the choke to kill it. When you start it full of Choke pull a cord once it wants to start turn the truck off then it starts immediately I watched a the video, this was a great help.

I read a lot of reviews prior to buying. I purchased this saw in Oct 2022. I did a review on the Garwinner 20” 62cc saw (love that saw too). There is a learning curve with this saw. 1. Don’t pull the throttle before it starts. 2. Pull the choke fully out and pull until you get a pop. 3. Push choke half way in and it should fire right up. You still need to hold down the decompression valve and etc. as the directions state. I have some flooding issues at first, hence is why I wrote do not pull the throttle while starting of before trying to start. I love the full chisel chain that it comes with. I use it to plank out large logs. I have fell one tree and bucked it. It is a heavy saw compare to your 20” saws. Roughly 30 lbs. It has been great for me. I’m an average size man and can start it fairly easy. The saw sat over the winter and fired up on the fourth pull. The initial pull on full choke, second pull on full choke and got the pop, move to half choke and turned over and stalled, and no choke with start up two days ago. I highly suggest hearing protection, the muffler is wide open and is extremely loud. I think it’s 105-115 dB. I will be using it a lot more this year and will do another review with an update maybe around autumn or so. This saw needs a check on the bar oil before refueling. I hope this helps you out.

I always had a hard time tightening the chain on this. The bolt that tensions it apparently had a small break or bend almost from the beginning, it seems. When it broke I replaced it with another bolt, but it was a bit short and it bent and allowed the chain to loosen. Looking for the $1 bolt without having to buy a $30 hardware kit. IF you can start the thing it’s great. Unfortunately I’ve spent about 4 hours trying to start it and 4 hours cutting wood with it. It WILL flood when you try to start it. Period. It just WILL! If you can get someone to pull the trigger while you try to start it that helps. I use a re-usable zip tie. Without that, I’d literally be unable to start this, period! I read reviews that said you’d better be STRONG to use this saw. That’s true. But you’d also better be strong to START this saw. So far I’ve used equal amounts of effort for both. I hate this saw. I gave it 2 stars because it is great IF you can get it to run! Edit - moved to 4 stars. The carb idle (L) has to be adjusted in order for it to start reliably. Weird, but ok! I had to turn it clockwise to give it more gas to start up. Then I had to turn it counter clockwise to back it off to the point where it wouldn’t run the chain without the throttle trigger pulled. It didn’t make sense because it was flooding the engine, just spitting gas into the spark plug. It’s supposed to put enough in there so it creates a vapor. I’m not sure why increasing the flow caused the problem to go away, but I’m glad it did! This saw is cheaper than a Stihl but it’s still not inexpensive!

Assembly was easy, minor adjusting to the carb. It's a long bar and chain so there is alot of adjusting once using it. Has plenty of power, I use it solely as a stump saw.
