Mine came in today, was covered in bar oil but looked pretty clean otherwise(oil tank was almost full). It was used for maybe one cut(a touch of chips under the brake along with some pine needles). I gassed it up and it started after 4 pulls. Sounded a touch lean on the high side but was a little rich at idle. Now to rip it apart and make it more gooder! I'm going to take it in stages, plan to just open up the muffler and slot the mixture screws for now and run it for a while then I'll dig deeper into some porting. I did pull the muffler already and the piston was pretty clean, no scratches on the skirt or anything.

You will have fun with these little saws. They are surprisingly good for the money and you will want more...just dont buy one until the seller lowers the price to a more reasonable amount. All the info you need on these is in this thread...have fun!
 
Looks exactly like a different color 'Quake to me! All saws are beginning to look like'Quakes to me!
:cheers:
What color would you like?

There are differences beyond different colors and styling of covers - metal handles, and the shape of the recoil cover where it goes around that rear A/V mount. On the Earthquake it goes all the way around, but on these and the real G3800 is does not. Or perhaps you'd like a Poulan Pro:

There are so many copies/clones - I can't imagine they are authorized for all of them, but then I can't imagine major retailers here could get away with selling something stolen either. I'm very curious about the arrangements and arrangements.

For those talking about buying in bulk, that is what the Earthquake folks did, and they did a pretty pro looking job too with the website and manual and boxing, etc. But it still isn't easy, and here we got the results of some failure on their part for cheap.
 
I noticed sears has new 41cc versions on their website marked down to $119, not that I'm interested.

It looks like I'm not going to get the last auction 3814. I've been outbid with all day to go. No matter. I just got an email from Bailey's with an offer for $.49 ground shipping. I can buy a couple of their close out 14" bars for less than another saw that I don't need. I ended up with three of the earthquakes anyway.

I wonder what the 16" bars will bring on the bay?
 
Dammit Jim; two more boxes were on my front porch when I got home

One saw was clean and one had been ran; first one I don't think has seen the light of day
 
These are cheap enough to play with, I opened up the muffler on one of mine and as soon as I find something to seal up the base, I'll remove the gasket just for fun. Of course I'll have to look around inside and see what else I'm brave enough to try.:msp_scared:

I use 3-Bond on all of them. Works great ! Northwoods carry it.

If you have a local Yamaha dealer you can swing by and pick up a tube of Yamabond4 for about $10 - they'll have it at the parts counter. I messed around with other stuff and then kicked myself for not getting the right stuff sooner.

It's been cold here so I decided to try the warm air inlet for the air box. It's 4 screws to get the top cover off, not as bad as I was thinking after having done more disassembly to pull it farther apart.. I had just sharpened the chain and ran it cutting off a few cookies on a 12" walnut log and then noodling a few pieces. Afterwards I checked the temperature of the carb body and it was definitely warmer than air temp so it seems it works well.

That just points out that the small RedMax saw designs are really very good - about the best out there in my humble opinion, even the older non-strato designs - and the manufacture is good enough that it didn't screw it up. I'll chalk up the cat muffler and tiny ports to a cheesy attempt to meet emissions. If you look at the design objectively - metal case, adjustable oiler, good A/V, very light weight, even a warm air setting - this thing blows away many expensive name brand saws, and the Chinese version preserves that. If it holds up it was a heck of a deal. I paid more for my GZ4000 Mac clone - a better saw with strato but used and from 2005.
 
You guys got me ! Had to go get one of them things to play with. LOL This one looks like its never been ran?

I knew you'd be in before it was over. I'm really surprised it took you this long. The muffler is REALLY restrictive. You have to open it up before you can do anything much with the saw. Have you checked the compression yet?
