Why do "Chinesium" chainsaws need a richer oil mix?

[ammoaddict]

Corporate America has Lawyers on staff that advises management of the cost incurred by infringing patents. Especially if it looks like willful infringement. Even the Chinese sawmakers are scared. See the gasket covering the nh843 strato port

So you think that was intentional and not an oversight?

And it's not a gray area. They are not legal for sale in the US. They are in violation of the clean air act.

Nah, they're perfectly legal for sale here in the US. Otherwise, we wouldn't be able to buy them so easily.

To get this thread back on topic, this neotec nh895 manual says 50:1

Regarding the nh843 strato cover.

It seems unlikely they would design in all the other parts of the strato system and just forget to open the gasket.
Given the performance hit if it was a mistake they would fix it promptly.
Strato tech is likely very important to any company holding the rights. Important enough to take action. They could probably prohibit import of the device.

I think it most likely they blocked it to avoid trouble.

I remember watching a video about the gasket. You could be right. I would think the patent on strato itself would be expired. They copy 372xtorq with the right gasket. I don't know how long the 543 has been out. It might still be under some patent.

I wish the made some drop in parts for my diesels to bypass all the EPA **** i'd be all over it. Emissions garbage is not enforced in my state luckily except for semi's they still have to comply somewhat at lealeas

They make such parts now. Many guys do the delete thing on their diesels.

I don't know much about the case. Did they block the strato ports and use a strato piston at the same time? Did they install a strato carb with a shutter (or an independent shutter) for clean air in this saw?

Because if not, it's nothing new. There have been chainsaws that use a strato cylinder with gasketed strato ports for over 20 years. Only such saws use a normal piston and a normal carburetor.

I don't know any of that. I just saw a video on YouTube where the guy cut the gasket out and said it ran better.

Show me an Amazon listing for crack

I found the video. This Zenoah GZ4350 (aka Husqvarna 543 XP) clone is indeed a strato saw and in this unit from the video the strato port was blocked. I wonder if they supply it like this all the time. Of course, Zenoah's original patents have already expired, while they have another patent for the strato engine from 2010, which is still protected.

I know more than one came like that. A guy on another forum bought one and said he cut it out also. No clue if their still shipping like that or not. Them had them on Amazon with some kind of discount for like 139, I started to get one until I found out about the gasket. I just didn't want to deal with it
I have too many saws now.

Good price. Interestingly, in the Japanese price list, GZ4350 costs less than G5201, decent clones of which can be found for around $100. But of course, these clones/copies/licenses of G4500/G5000/G5200 have been around for 20 years or so, and GZ4350 is a relatively new model.

No, but you can't be counterfeit knocks offs of all kinds of stuff on Amazon. Including ones that at the least infringe on trademarks.

There was some real redmax 4350s for sale a few months ago, I think at rcpw for $350 with 16" bar and free shipping. Several guys on fhc bought them. They all like them. I wanted one but couldn't swing it at the time. I think they're out of stock now.

If they were illegal to sell, they wouldn't be for sale on Amazon. I'm guessing they're able to skirt certain laws because technically they aren't selling a complete product, as you have to buy the bar/chain separately.

Regardless, if they are legal, they would be certified/listed and would be labeled as such. They are not.
So the if they are sold on Amazon they must be legal is a bunch of BS.

Provide one example of them being deemed illegal. A single repercussion. There are dealers selling them right here in the US all day long.

In just told you why they are illegal. As for prosecution I don't know if it's happened ever. It never happened to the diesel guys selling deletes until it did then they came done on them like a ton of bricks.

Laws are made via legislation and I don't recall any banning chainsaws from China. You originally claimed they were illegal because they were counterfeit, and you were proven wrong. So now it's they're illegal because they're not on some EPA list. The EPA doesn't make law either. When they aren't available for sale in the US through multiple distributors and dealers, then we'll call them illegal!
