#$%^ Chinese 660 Stihl clone saw.

[windthrown]

Well, look on the gun threads... Norenco gets pretty high marks. I have a Norenco 1911 and people laugh at it until the fire it. Then they all... every one of them shut the fork up. Including many an ex Army Ranger and Navy Seal. Its dead accurate. I would put it up against *any* colt out there. Now it was tricked out by a gunsmith during the Vietnam War, has tritium sights, 3-hole trigger, and Pacmayr grips, but its still a Norenco frame gun. My brother has a dozen AKs, and the Norenco ones shoot the best. I personally do not like any SKS or AKs, but they are the better ones I have seen. Each to their own...

Compared to the junk knockoff chainsaws that they make in China... way better. I am not a China fan of anything really, but I will never sell my Norenco 1911 handgun.

That kind of means you lucked out and got a good one- same can happen with the chainsaw copies, every now and then you get a real good one- but it is more the exception than the rule perhaps?
Mind you, they do have a large regular army over there- guess firearms manufacture might be more up to spec than chainsaw copy manufacture?
I cannot compare Norinco handguns or military rifle copies- have never owned either- but will stick with my impression of the .22lr models (of which I have owned several) and while they function, they are not anywhere near the standard nor accuracy of the European models they copied. It is extremely handy though that the JW 15 magazines fit the BRNO Model 1 perfectly!

I think many of the firearms they made were manufactured to a higher standard than their usual consumer goods due to their relation to the PLA. Still, I haven’t been very impressed with Chinese guns. Some of their cheap optics can be a nice way to scope a rimfire or precharged air rifle though.

My own feeling is that they suffer from two big handicaps when it comes to manufacturing firearms. The first is their seemingly innate tendency to cut corners wherever possible and produce goods of dubious quality. The second is their utter lack of any kind of gun culture. People who don’t have the trigger time just don’t understand what makes a good firearm, so when they produce a gun they can’t really innovate or understand when something is flawed. I’ve felt for sometime that their QBZ95 rifle is a prime example of this. The length of pull on it is massive and considering that the average Chinese soldier is of smaller stature and will likely be wearing winter clothing or body armor, bringing it to the shoulder and quickly engaging a target will be much more difficult than it would with an M4. I’m guessing however that hardly any Chinese soldiers are even aware of it, considering it’s probably the only rifle they have ever fired.

Lol I guess if buying two of everything to get one good part is your definition of success...

I do not have any kind of saw that I do not have two of. Three pairs of Stihls and three Huskies 460 along with my Huztl saws. A failed saw is not an option for me. very costly. Thanks

You would think he would have heard piston smacking cylinder head. Have seen a bottom rod bearing fail and blow cylinder off of saw. If he used a base gasket that should not happen.

Piston only hit top of cylinder because of crank rod bearing. Rod can be pulled up and down 1/8th of an inch.

I had read of a couple instances where the counter weights were hitting the inside of the piston skirt and chipping off bits of aluminum and getting into the big end bearing and causing it to fail. I checked for this when I built mine and it was hitting. I took my Dremel and slightly beveled the inside edge of the skirt and it gave it enough clearance.

I worked on a guy's saw the counterweights hit the piston too. Had worn a notch in the piston skirt. I can only imagine the vibration that thing had. d

Nobody can have too many saws. When I was more able to do it, I had at least 6 if not more running saws at any time. I could only clean up around fields when weather was fit, no crops in field, and not too muddy so I would have all ready to go. Fueled, sharp. When 1 would get dull pick up the next. Also had 084 down to 200. Start with the biggest saw and the more tired I got, move down a size. When my back and arms could take no more with the smallest saw, it was time to go home. I also kept all ready to go so when storms or tornados hit I would load all my saws and clear roads. Road departments paid me back many times for that over years including 1 year I was in really bad shape, they brought me several truck loads of trees cut up (some pieces were firewood size) and all oak to use for firewood. I did not have to find trees to make wood for 2 years.

Very possible... It will be interesting to see how it turns out.

They are corresponding but want to know if doubling the cylinder gasket would fix it. I told them no, the bearing is gone and the rod can be moved up and down 1/8th inch. Sent photos but hard to tell. A video would have been obvious but take too much internet and time to download.

Only good thing China ever made were Norinco firearms.

Thank you for the stand with Hong Kong. I agree fully. Those kids have guts over there. Awesome guts. Cheers.

You're missing the part where someone repairing has to troubleshoot a bad part to know they need to order a new one in a bag...

A person has the expectation the new one in the bag needs no trouble shooting. You are missing that point that it was new. in a box, not a bag. I've not seen bagged crank assemblies for Stihl clones yet. Why buy new if they have to be inspected with the expectation they may be junk too? Just buy a box of used parts and sort through them if that is the case. I've not seen a bad crank since an XL12 Homelight 45 years ago. Some slightly loose but well enough I ran them for years yet.

 

[lone wolf]

You're going to find some guys here that SWEAR that they're not absolute POS. They'll probably even tell you that YOU assembled it wrong...

Sorry you got duped man. I try and tell as many people as I can, but that cheap price just keeps 'em drinking the koolaid.

 

[dls]

This!

I guess I don't understand the OP, you buy something such as this, and then ***** when it doesn't work out???? Really??? All I can do is SMH.

No surprise. My expectations have limitations as noted in issues I know they often have in my remarks. I've torn down many crapped out saws including 2 044's that had been underwater for so long it took an impact driver to remove the screws but the cranks were still good. Just letting those who might be interested know what other issues there might be. Nobody is running around in circles crying waving their hands int he air here.

 

[dls]

I re read the original post and I am unsure if the op meant the rod bearing failed causing the piston to hit or if the piston hit first causing the bearing to fail. It's very possible the bearing failed first due to aluminum shavings in it and then the piston hit the top of the cylinder.

I would cut my loses while I was behind....I have had two of the POS AM saws and you get what you pay for. SOme of the pasts are usable,but from my experience the crankcase, bearings, crank, cylinder and piston are inferior. You can get by with the plastic parts as China plastic is decent.

Anything not reparable is unacceptable to me. If it can be built it can be taken apart. If it can be built it can be rebuilt. Wife came home with 2 new garage door openers today. Gear stripped on 1. She says both have to match. I tore down opener and ordered gear for $3.80. Problem solved. They will match. No hackable WiFi/Bluetooth $400 openers. If they do not replace the part, I will buy my own. I liked the saw and it will run again as a bad ass saw. Already had a miller ask me if I could soup it up for him when I build it. Cheers

 

[dls]

Sh1t happens, things fail... I never said I have never had a dud. I said I have built enough to know what to look for and fix it during the build.. that being said, it sounds like the ceiling clearance was too low and more than likely was hitting the top the entire time. Most likely caused the failure. Op, I'll be here if you want or need anything.

How could it be cranked then? Especially when the compression release was pressed in? I do know people who double or triple the gaskets to lower compression to over speed them in the 16,000 rpm range but they still rebuild them often.

You missed my point. Totally...

It will crank if it is barely hitting, but it will destroy things. Much like described.

Getting service from them is not going to happen, if they in fact do anything it won't be worthwhile. They will offer you a credit. Their disclaimer on the website says if you build the kit into a complete saw there is zero warranty.
