Excellent Saw
Excellent saw! I have a Stihl MS 150 and a Stihl MS 261. I needed a large saw that would handle a 36" bar for a large maple tree that fell. The Stihl MS661 at $1,400 was just more than I could afford, so I bought this G660. I paired it with an Oregon 36" bar and chain. The pictures are from the first use. I figured it would take forever to make the cuts because I was running it slow for break-in. It didn't. It ate that maple tree for breakfast. Wow. Easy to start (2nd pull from cold, 1st pull from warm), runs smooth, and it just rolls the power on. I'm very pleased. One note: The factory does not set up the carburetor needle valves. You have to set them or the saw won't start, it will flood. YouTube Steve's Small Engine Saloon has a good video about how to adjust chainsaw carbs. Build quality looks very good. Hopefully it will last a long time.

Runs great right out of the box
Seem to be built very good. i put it together and put a bar on it, within 4 pulls it started right up and idled great as it should. I cut a tanks worth of wood with it the 1st day and it pulled a 24 inch bar easy without getting bogged down. Can't wait for it to get broken in and put a 36 inch bar on it.

Starts easy if you follow directions
Powerful. If you do not follow stsrting directions to the tee, it will not start.

Great saw has alot of balls
I have a 36 in bar on this 660 saw and it cuts the hard Juniper like butter I was hesitant but the only issues I've had so far was the chain adjuster which I would 100% recommend getting a stihl chain adjuster and to be very careful with the pull start must use the decompress valve or you'll end up breaking the string

Going the Distance
I was scared that this Chinese saw would be a piece of crap. I put a 36” bar on it and milled a 10’ long 30” diameter oak log into 8/4 inch slabs. It works great. The manual contradicts itself regarding the oil/gas mix. I bought alcohol free gas and mixed it 50:1 with Red Armor. It starts the same and runs great every time.

Was skeptical at first
I was reluctant to buy the knock off of the 660, but the price was just to good to pass up. I needed a more powerful saw for milling. I've been running this with a 42" bar. It's broken in now and running very well. Haven't had any issues with it, although I've only run about 6-7 tanks of fuel through it thus far.

So far so good. Started right up in 3 pulls!
Nice saw - solidly built. Started in 3 pulls! Seems like it was missing a screw - only three screws provided for mounting the handle. Handle was different than the one pictured but that's ok. The inner log dog will not fit without modification but I don't need them anyway since this will mainly be used for chainsaw milling.

china junk saw read all the reviews first
This Saw is not what they say it is. After break-in procedures the saw ran for about 10 minutes and the crank bearings came apart and the piston stuck in the cylinder. after a month of Emails and getting nowhere to get the saw replaced, ( they wanted to send parts out for me to fix the saw which you have to have specialized tools to do so) they finally offered to have it ship to somewhere in the USA to have it fixed and sent back, with no time frame. so if you want to be treated like crap and told if you don't do what they want your out of luck on the saw go with farmertec. Ojenas saws are much better quality did not have a problem with them so don't waste you money on farmertec , read all the reviews before making a choice
