The 070 I have is most definately a fake as I bought it from China. Build quality from this particular manufacturer was quite poor. For those people that think they'll be able to spot a good fake? Think again, you more than likely won't.
A few months back on an Australian forum somebody started a thread about a "Genuine 070 on Australian eBay". Everybody was replying "Wow"..."Buy it"..."You won't see another one"...blah blah blah.
Anyway, some gullible individual paid from memory around USD$1100 for it. I saw this and did a quick search of the seller. What do you know? He'd sold a few "genuine" 070's prior and had another one listed the second the above mentioned unit had sold. I was going to report this seller but the next one he auctioned he did state it was made in China. Prior to that he'd mentioned Germany.
There are many different sources of 070's in China and I have no problem telling guys on AS what you can land one of these to the states for...
Around USD$270 brand new with 30" .404" Stihl labelled bar plus Stihl branded RMC chain.
Now let me list the problems...
1) Choke linkage won't stay on.
2) Filter fit is very poor.
3) Clutch slips at the slightest provocation.
4) All the allen bolt heads have been overtightened and damaged.
5) The carby is a poor rip off and adjustments don't respond very well.
6) Even tuned to it's best it is gutless but as mentioned above it does seem to be 107 odd cc.
This saw is really only good for a few spare parts for a genuine 070.
Don't take the risk buying one of these saws unless you get it dirt cheap. There are good knockoffs of some other saws but from what I've seen and heard the 070 isn't one of them.
Wayne (gmax) doesn't know this yet but when he comes to visit in a few weeks for some chainsaw fun I'm giving it to him for nothing. He may just throw it in the bin when he gets home or maybe with his expertise he can get it running properly
