Holzfforma 92cc Farmertec Blue Thunder G660 Chain Saw Power Head ONLY. All Parts are Compatible WT MS660 066 Chainsaw

I am almost entirely pleased with this saw. I use it in an Alaskn CHainsaw mill. Things I like. It has power starts up fairly quickly, was relatively inexpensive and does a great job. Best of all it is such a great knock off that Stihl parts are interchangable. Chain adjustment screw stripped after a couple of uses, but I bought another on Amazon cheap and was back in business. Saw had trouble starting after a few uses and I was frustrated, but I diagnosed the problem being electrical. An minor ajustment of gap on magneto and it starts and runs like a champ...I mean Stihl. Parts are fairly cheap plastic but it seems to be holding up. I paired it with a Holzforma 36" bar and chain and I love it. The whole rig is heavey though and loud. Wear ear protection. If you don't have the money for a Stihl and are patient and not a pro. I recommend this product. I've had it for almosta year now and it uslly starts right up, but engine is prone to flooding every now an then so I need to let it sit a while before it will start again. Definitely worth the money.

I've heard good things about these. Recently I've had to cut some very large trees, larger then any saw that I have could handle. I've always had stihls and Husqvarna saws. Needing a large saw, but couldn't justify or afford a $1800 Stihl ms660 I took a chance and bout this one.... Let's just say I just ordered a second one, just have. Saw has massive amounts of power and with a 28" bar I got the job. Done with no issues at all outta the saw. Now with a larg r saw I can take on larger tree projects. There are all kinds tios out there on how to improve this saw for very lil $$. Of course the folks that went out and spent big bucks on tops shelf saws hav nothing good to say, but I think it has a lot to do with what they've spent on them things. Like I said I liked this saw so much I ordered a second saw just to have or to resale. Can't go wrong with this saw. Now after a few big tree jobs and Dailey running for weeks. This saw is an official badass.

Runs good, have cut quite a bit of firewood with it, seems to leak bar oil but not too worried it’s a lot of saw for short money. I’m running a holzforma 25” bar and she screams. Running it 28:1 mix as it says in manual to run 25:1 but that seemed a little too rich.

It's a defective product, never was able to start it. Adjusted the carburetor, bought top quality spark, used non ethanol gas with a correct (1-32) ratio, pulled hundreds of times with no result. Amazon and the seller refused to return/refund/replace it after several attempts. There was no customer service provided at all. Please never buy it from them. Lost my money for the junk.

Great saw for the price have had it for a year now and no problem. I left gas in omit over the winter thought i was going to have a problem but started up in under 20 pulls.

The media could not be loaded. This machine is absolutely fantastic! Just like many other reviews, I was searching for a powerful chainsaw without having to pay over a thousand dollars for it. Seeing this chainsaw, I thought it was too good to be true for the price and getting 92cc. But it is completely real and unbelievable.I got this saw to use primarily for milling on a chainsaw mill, and it has yet to let me down! It flies through everything with ease! Most notably, I milled 3, 6 foot long Black Walnut logs that were about 20 inches in diameter and it would take less than 90 seconds to rip through each pass!For my machine, I paired it with a Neo-tec 36" bar (3/8 pitch, 0.063 guage, 114 drive link). I bought this on Amazon as well, and they had a combo set that came with a standard chain as well for only $20 more. For milling, I paired it with a Woodland Pro 36" ripping chain (33RP, 114 Drive link).Only issue I've had so far is the gears for the tensioner are cheap and started to grind themselves down so I have to tension it by hand/with help from someone pulling the bar out as I tighten it down. I did find that the tensioner for the Stihl MS660 fits in this machine as well and is much better quality

I've used this chainsaw to mill through a single ~30 inch red oak so far.The first part to go out on me was the tensioner and this was pretty much right away. The parts that they use for this I believe are made out of aluminum and thin plastic. I was able to tighten the chain once before the whole assembly was stripped and completely unusable. Before you use this chainsaw you should replace this with an actual Stihl tensioner assembly as the difference in quality is night and day.https://www.amazon.com/dp/B003RJT81S?psc=1&ref=ppx_yo2ov_dt_b_product_detailsThe chainsaw also seems to have some issues with it's seals as it leak a fair amount of bar oil and fuel compared to my other saws. I have yet to fix these issues as the saw does run fairly well so far, but likely will need to be addressed in the near future.All said the saw has operated well so far with no other major issues. I've heard of others stating that their starting spring snapped which hasn't happened to me yet, but it's a part I'll be replacing soon as a precaution. But, so far the saw has been good. If you're looking to purchase as your first saw I would recommend buying Stihl parts to replace what others have had trouble with from the start before first use. Especially the tensioner assembly, every part in it is junk!I'll try to update as I get it through a couple more logs.
