dissecting an earthquake chainsaw

[Rudolf73]

On the original or the copy? I don't know much about the G5000 other than looking at an IPL.

The copy, the original Redmax seemed so be a reasonable saw or so I have read.

Welp, got #2 out today for bucking up some 14 to 16" poplar, and it never missed a beat. And surprisingly, really wasn't much slower than my buddies 38cc 16" Echo. Did hit something in the wood in the last bucking cuts, so the 500 ended up cutting up the second poplar.

Yea, the 500 was faster, could be dogged in and still cut, and threw bigger chips of course. But the Quake is easier on the hands with its spring AV and is noticeably lighter. For the small diameter wood I usually get, its perfect for that.

For the price, these little misfit saw just keep on impressing me.

OK - maybe the clone would do better if they put the chain on the right way! Or is that the Australian version?

Seriously though, I wonder how it would run if given a decent porting?

Drank the koolaid on a couple of these 38cc saws recently.

Saw number one I tore down, widened the exhaust side of the cylinder, MM, pulled the base gasket, and cut the slots for the jets. With a sharp chain it runs/cuts pretty decent (for what a 40.00 chainsaw is).

Saw number two I skipped the cylinder mod and only did the MM and the jets for the carb.

Couple picks of number two's MM...

Pencil out an area to aim the drill bit at.

Then go crazy with whatever bit is in the drill press. Then pull this piece of metal out the front. Needle nose worked because I could keep on rolling the pliers till it popped out.

Next punch the holes through the next wall of metal. This will bypass the lower part of the muffler.

Once the screen is back in place it looks stock again.

On to the carburetor.

Before.

After.

Side note. If you shave a little plastic off to the right side of the throttle rod, in the handle, it makes the install much easier.

Looks like the BIN prices have been raised to $35, $45, and $55 plus $15 Shipping. I'm out at those prices. We'll see if others feel the same. So far no takers.

Just paid for two more saw this am; all I do is pull the carbs off and use a cutting wheel and make the carbs adjustable with a regular screw driver and mm them and they sell like hot cakes (or like coffee table coasters) to alot of Norwegians here were I live.

That is the quick easy way to mod these saws.

After running both saws I modded I could not tell a significant difference. I turned one bar upside down so I knew which saw had the cylinder modded...:msp_confused:

I'm sure porting would improve performance, but I never got around it on the ones I was playing with.

Would it be worth creating a separate Earthquake tech info thread? This one is so long it is hard to find anything in it. Or would it create an AS revolt if the Earthquake stuff spreads?

Check the compression and tune, the opened up one should run a bit stronger. One thing I have found with all my saws is tuning in the cut makes a world of difference, it's like setting up a SBC by making passes on an abandoned street verses a timing light and carb screwdriver in your shop, no substitute for real world testing.

Not as far-fetched as it might sound, especially if ours continue to perform without problems and we continue to extoll their virtues

Got my first saw delivered today. Looks like it may have been used once but the bar shows no wear. No chain was included. I emailed the seller, hopefully he sends me one.

If anyone would like to have the chain adjuster that is accessed through the clutch cover instead of right next to the bar, you can order this:

I ordered one for my saw to see if it would work, it dropped right in and works great. Here's a link to the site I found mine:

Which Earthquake does this fit, I don't remember a hole in the cover on the 3816, fill us in some more.:msp_thumbup:

It fits the 38cc for sure - it's like the one on my McCulluch GZ4000 clone.

Got 2 more today!!

Both were used, thinking that he had sent out the cherry ones to begin with, and is now getting out the used ones. Both had seen wood and had sawdust and gunk on them. Some scratches and some peeling stickers too.

First one.

After opening the second one, here is a first for me!!!!

MIX OIL!!!

And warranty registration...

Second saw..

WAAYYY too cold to pull the muff, peek inside and do the carb mod, but both seem to pull over well. The Fast Tach is arriving from Edge and Engine, so will test it out on the first 2 Quakes, just to see how close I was on the tune. Was a little rich on the first one, but think I got the second one dialed in pretty well, so am curious to see what RPM she's turning...

ETA: apologies for the upside down pics, I fixed those in Photobucket, but for some reason it won't apply the rotation here..
