dissecting an earthquake chainsaw

Help Support Arborist Forum:
Well the last of my Quake purchases arrived today and it appears to have some serious run time on it and the chain is unusable, looks like it caught the catcher and mushroomed up the drive links, this gives me an excuse to get a real chain for it when I go out tomorrow to restock my carb kits for all the broken snowblowers that have shown up recently.View attachment 275172
looks like mine did. My theory is that the original owner didn't read the instructions and remove the yellow plastic thing before mounting the bar/chain...oops.

Looks like the era of the $40 chainsaw has come to an end
Now the listing has been changed to describe the saws as "refurbished" instead of for parts and the price is $80+ including shipping. I am the high bidder on the last auction 3814. I hope I win it. I'm primarily interested in the 14" bar since it seems about right vs the 16". I'm definitely out at that BIN price. The seller has an interesting tactic. Raise the price and if they don't sell raise it some more.
I did the quick and dirty muffler mod but I think I opened up the outlet a bit too much (loud). I may weld a washer over the screen holder/muffler brace to cut it down a bit. I opened up the muffler and drilled about 25 eighth inch holes in the inner baffle. I doubled the size of the hole in the brace which was a bit much.
It read 165# of compression on my gauge. A little tweaking of the mixture screws and it is turning 12.5k rpms and idling and revving like a champ. I have the set of adjustment tools so i didn't bother slotting the screws.
Compared to my GZ400 it doesn't seem to carry the same rpm in the cut but it seems to have a little more grunt when you lean on it. I am pretty impressed with the saw I have to say.

It will go down again...no one here which is his best customer group will buy at that price...and if you guys do...ill neg rep ya!:msp_biggrin:
I'll eventually take the dremel to the links and then sharpen it on the 511 so I can use this bar and chain on a freebie sears saw I'm fixing for a guy I used to work with.

I don't have a compression gauge or a tach so that is interesting. That's without porting? I wonder hwat mine blows without the base gasket. It takes a decent yank on the starter cord.
I agree in reference to the GZ400 / GZ4000. They both feel very similar since the chassis is pretty much the same.

Yep, muffler mod only. No porting. I didn't pull the base gasket since the compression seemed pretty high as is. I just wanted to run it so I didn't get too deep. I didn't even check the squish. After reading lots of threads it seemed the MM gave the biggest gains. I suspect the carb/intake is the limiting factor with porting. It four strokes pretty good out of the cut at 12.5k and cleans up nicely under a load.
It would barely run out of the box. It was way lean on the low side and way rich on the high. but the cylinder and piston looked like new.

The carb is exactly the same size as the one on my 42cc Craftsman/Poulan, both throttle and venturi. It does not seem to restrict that too much, so I figured it was sufficient for 38cc. I have noticed it 4-strokes like crazy and does not sound like it is revving very high, but it does have a lot of torque for 38cc. Maybe there is something about the carb design - I have not opened it up. Wonder where the metering lever is set?

Looks clean - is that the first one you got? Will be interested in your impression. The stickers come off easily if you let the saw warm up (the cat muffler does this well). I peeled off the ones on mine without leaving any stickum or backing at all - looks much better IMO.
I spent a few minutes with an X-acto cleaning up the flashing on the plastic, which was pretty bad. It made it look much better. I even cleaned up some flashing on the two air filter halves so they would fit together better. Like I said before - it is a chainsaw kit.

The sprocket has some faint witness marks! It's probably one of the ones he is now asking $70 for.

Odd ain't it?
My first one was brand new, never used for $35, but as I've went along and paid more ($40-$42.50) they've become more and more used...

Quick update: Added some mix and bar oil 4 pulls and presto, let warm up a while. This thing is sweet and given the temp outside the carb seems to be pretty close. I think I got lucky getting a like new one, or I owe 08 the snackie up the road.:msp_ohmy: Troll don't know what he is missin'
