92cc Holzfforma Blue Thunder G660 Gasoline Chain Saw Power Head Without Guide Bar and Chain All parts are compatible WT MS660 066 Chainsaw

I have been using this on my Alaskan mill to cut slabs. I have a 24" bar on it with a Grunberg ripping chain. Has gone through wet maple and wet cedar like butter. When I first got it, it took a while to get it started, but part of that's on me as I wasn't following the proper procedure (the instruction manual is not great here, but plenty of YouTube vids out there to help guide you through the procedure). I also replaced the spark plug that came with the saw. Once I got this done, started and has run like a champ. Now it starts no problem. This saw is soooo worth every penny.

All may tools are made by stihl, bought this saw for price and will not have a lot of use for it , could not justify $1800 for the real deal In short saw was well packaged , started on 3rd pull/ and starts easy no more than 2 pulls , ran two tanks of fuel so far very good , on first tank I let her idle the whole tank with throttle snaps every few minutes, she ran a big ruff on first tank but o did use a 25:1 oil mix for break in , second tank 40:1 mix saw smooth out, running very nice, did some very light cutting to break in bar and chain and saw after every cut. I let her idle for a few minutes did that through the whole second tank, I’m very happy with the saw so far I’m gonna take it easy for the first five tanks before I put it on the Alaska mill , I’ll use it for a few months and let you guys know how she’s doing, but for the money very very happy

Lots of power can use a sthil bar and chain on it I have a 32 inch bar n chain on it!! leaks gas when sitting and bar and chain oil but what chain saw doesn’t had to adjust the jets alittle but rips threw wood! Always make sure the nuts and bolts on the hole saw are tight after running it the first time or the first 30 mins!! Well worth the money instead of 1200$-1500$ for a sthil chainsaw that and no stupid California regulation for the engine!

Let me start by saying, I ordered the "Blue Thunder" model... because it's blue!! What I got in the mail was the Orange one you see in pic 3... slight disappointment. Other then that, the quality of this powerhead is better then a previously purchased powerhead from a different company. Better quality product. Filled with recommended gas/oil mix and b/c oil Fired up on 3rd pull. Sounds great and cuts great! Just need to make sure you take it easy on the first 4-5 tanks of gas for the "break-in period" about 1/2 - 3/4 throttle to start out. No wide open till the 5th tank. The wood in these pics are a hard wood oak tree and a water oak.. It cut them with ease...using a 36" bar and chain with a milling attachment... great product, great customer service, quick to respond.

2nd G660 I've ordered. 1st one has been fabulous for use on farm andstill runs andstarts easy. This one has been used once for 20-30 minutes last fall and was difficult to start then. It acted like it flooded but finally started. Tried to start it March 5th but couldn't get it stared. Checked plug and found there is no or very low spark. Suspect a bad coil. Emailed seller waiting response and will update this review accordingly. Hope they stand behind this since I've recommended it to friends and family.

Runs well, cuts nice. The pull rope coil malfunctioned within first 20 starts. I replaced with one purchased from Amazon for a Stihl 660. I don't regret purchasing, but the saw is made cheap, and I don't expect longevity.

Love the price bought three 338 hasn't arrived 466 660 both in use as I write this review 660 cutting teeth on some white oak shortly out of the box checked all bolts people said they had issues with found all to be tight seen so many suggestions on the mix I'll stick with 25 :1. Till proven otherwise these saws are run hard and all day don't think they will be issues with build up seen couple blow from other logging companies running 50:1 and for the critics first two white oak logs together brought 1,000 all three saws payed for with a little change left so I ordered another I think I got that video in and only I must stand in my shoes and I chose not to wear ppe so please be concerned for your safety this is my 36 year in the business so I don't have to worry about making it another 36 if something does go horribly wrong maybe you do I almost forgot value for the money not to light easy to use unless your a beginner do yourself a favor order a lite bar I did old man can get up and down those hills and rocks now Timber man out

Runs great! Took it out of the box put a chain and bar on it a little gas and oil and went to work.
