I've started threads before on this as I have previously imported a couple of 365 knock offs as test mules for some big bore kits I was also importing. I copped a lot of flak from it but I can assure you I have a MAJOR issue when knock offs are being sold and badged as genuine Husqvarnas. Mine were not labelled as Huskys in any way and although a blatant copy were labelled HH365 saws with absolutely no dodgey ID plate or anything like that. I can assure you that if you'd have changed the stickers on the saws I had, whacked an NGK plug in it, and put a non Chinese branded carby on it most members here would not be able to tell the difference - the particular examples I had were a bolt for bolt knock off and are still running well. I gave one to an AS member here who has fitted an off it's face BB kit on it and has had absolutely no issues - another Australian AS member has the other one. Even the 65cc cylinders were top quality and as good as genuine (no joke!). They were labelled B&B - Italy. The Chinese are even copying Stihl ES bars and RMC/RSC chain. Even Stihl dealers wouldn't be able to tell the difference. I also have to be honest in saying that the single loop of 3/8" .063" RMC chain I was sent has also held up OK and is still going strong.
The only way you can be certain you are getting the real deal is to buy from a dealer or somebody reputable. Some of the better copies are impossible to tell via internet photos. If it's too good to be true it probably is! The Chinese are untouchable when it comes to patent laws - just try to start a court case with them. It's easy to disappear in 1.5 billion people and there isn't just one company knocking off Huskys, there are at least half a dozen. Copies range from the earlier bolt on intake 365's right up to the latest versions, complete with tougher cranks. To give you an idea of what the price was freight from China cost nearly as much as the saw!
All legalities and morals aside these were the saw bargain of the century. I have also turned down numerous offers via email and PM's from AS members wanting details on where to purchase one. Because I dealt with a Chinese 3rd party even I don't know who the manufacturers were.
I have also sat one of these saws side by side with a genuine 365. Apart from the copy being slightly heavier (plus the stickers and ID plate) they were near a mirror image apart from different mufflers. Even a genuine Husky HD filter kit fitted perfectly...
Also note that it's been torn off on the box the OP's saw came in. I'd say the seller knew it was a fake.
Where do you think all of the aftermarket Husky parts are coming from anyway? No need to wait for blow ups. Just check Bailey's aftermarket spares lists
I can buy whole 365/372 tank assemblies for USD$19, cranks for USD$15 etc etc. How the hell they make these so cheap amazes me AND my 3rd party Chinese friend was also putting extra on top too.
