This is the first saw I've ever put together from parts and it assembled perfectly, I did it in one day. Small adjustment to the carb and it runs perfectly. i will probably buy another one.



I bought my kit in April and I have to say it was really fun building the saw. my kit wasn't missing any parts and it all went together very easily. It has a lot of power! I ended up replacing the crank seals, clutch, handle bar( mine bent very easily) and oil pump. All in all very happy with the saw and I just put together another kit saw ended up going with the 372xp clone but I see they have the 046/460 kit now so that's next on my list



Saw went together as expected, ran approximately 4 tanks of gas through the saw so far and it was performed well.

Love this kit easy assembly and quality parts at a bargin price, this saw is proving to be extremely reliable.



I ordered and built a 660 kit for a friend it was all very good quality - 1 or two small parts (mine was very early kit so problems resolved now) I enjoyed putting everything together and running the saw afterwards it cuts very well with lots of power spare even on a 36” guide bar and chain. I would recommend this kit to anyone and will buy again myself.



I love this saw. Always wanted a 660 but never really needed one especially because of the price. I put this together in about 3 hours. It fired right up and ran great. Have one tank of fuel ran through it mixed at 25:1. So far awesome saw. And I plan on buying plenty more.

the 660 kits are really good value for what you get. Very capable saws for bucking or running a mill. Have a look on youtube for bolt by bolt videos. Take your time and enjoy.

Never really expected to be building chainsaws, but after watching several people building these saws on youtube with great success, I thought I would give it a shot. I had a few things I had to swap for OEM, but very happy with my purchase. Saw runs great and I now have plenty of confidence to work on saws and I'm loving it. New hobby! Thanks Hutzl!!

Has anyone had any problems with the handlebar on MS660 ???



Es handelt sich um einen Super bausatz, am besten für Leute die schon ein gewisses Grundwissen mitbringen. Mit ein paar kleinen Veränderungen ist sie Perfekt.



Awesome saw just missing a few bolts



Bought this kit a month ago with the big bore kit also.. all parts were of really good quality.. both cylinders were really good, coating was perfect did not have to touch it other then clean before putting it togather.. nothing was missing went togather really easy only issue I have with it is chain adjuster.. have a factory one ordered. Was a really good project and man do it have power. Awesome on my chain saw mill.. plan on ordering the 361 kit next...

Assembled 2 of these. Did some tuning and cutting with 28 bar on one. Worked very well.The second broke the recoil when the decomp valve closed as it was firing. Ordered some extra recoil parts and they are here now. That one has the big bore kit. If it works as well as the other I will be happy. Was missing a couple screws. Chain tensioner is poor quality.



This was my first build. I took my time and everything went together perfectly. I did replace crank seals and bearings because there were a lot of aluminum shavings in the crankcase and the seals from when the crankcase bolt holes were milled. For this reason, I wish they did not assemble these parts before shipping. Make sure you check for this before just slapping everything together.

You may find that the supplied bar/chain adjuster is a little rough and difficult to work. You can track down a OEM Stihl one (which will definitely work more smoothely) or you can just pack the supplied one with grease and deal which does help.

Other than that, the saw has treated me well. I've got a 28 bar on it and have used it to cut and mill a number of large mahogany trees. Plenty of power and reliable so far.

A new Stihl ms660 in my area is about $1500 new, so at about $300 delivered this has been great.

kit was missing carb bolts but other than that was complete and fun to build. used matt o's bolt for bolt youtube videos. runs and cuts great

I finished putting this saw together recently and really enjoyed the challenge. I had two piston cir clips missing and the plastic cylinder shroud had a small fracture where one of the brass grommets were pressed through. I think most of the parts are good and they have inherited much of the OEMs original quality. One exception is the chain tensioner it needs to be shimmed to keep it aligned. The cylinder was clean without burrs. LOTs of compression.
Service:Thanks for your feedback. If there are some items you can not use,we may make a partial refund for you. Thanks.

You will have to ajust kill switch by bending it to shut the saw off. The chain adjustment is useless made of alloy most likely aluminum does not work at all you will have to switch to the Stihl OEM part. I recommend using OEM on throttle control weak and raddles around along with kill switch. The clutch drum is a little tight but you can get it to work. Other then this few issues a fantastic saw and an outstanding value

We purchase these saws to build and resale. Saw went together really easy. A few things to note: there will be parts missing. Only reason I say this is because we have watched plenty of youtube vids and just about all have said they have had at least a couple things missing. Really it is small things. Mine had the carburetor flange nuts missing and also had the wrong bar studs. The seals come already installed in the case halves. Makes it difficult to install the crank without reversing the seal.
With that being said, just order a seal kit, they are really inexpensive. As well as the flange nuts for the carburetor. other than that, the saw fired right up and seems really strong. Will buy more.

First time building a saw. It went together easily. Chack YouTube for bolt by bolt videos. Saw stars easily and oils well.
