Interestingly, the one without the base gasket seems to blow about the same compression as it did before the base gasket come out.

They all run great!
That's strange - did you measure before and after? If removing the gasket didn't change it then there must be something else limiting it - ring seal? If so it may improve in time. The machining looks a little rough so it may take a a little longer than usual for the rings to seat.

From what I've seen with these you are on the right track with them taking a little longer to seat the rings. When I removed the base gasket on mine I noticed it was very thin. I think it was the thinnest material I have ever seen in such an application.

As far as all of the other comments on where the saws originate and where our money goes... I didn't come to this site to argue political ideology or economic theory. I came to learn about saws. Well, I actually started wanting to learn how to sharpen chains. Which led to tuning my own saws. Which led to muffler mods. Which led to porting. Which led to timing advances and increased compression and hotter sparks and faster cutting times for the sake of faster cutting times.

I just want to talk about saws. I'm glad 08 started the thread and hope he finds another source for similar saws. I'll jump in on that just as fast as I jumped in on this.

By the way, my saw runs faster than all of your saws.... :msp_razz:
 
HUSKYQUAKE that I've done the most work to the compression didn't change much (149)

The three I still have in the box are all over the board when it comes to compression but nothing below 140

They are just well built...plain and simple.

If I had bought one and stumbled upon this site and thread, I would feel ripped off but would see how many have enjoyed them and feel justified...that at least I got a decent saw.
 
I had my first outing with the Earthquake today. I ran five tanks through it cutting tree tops that were logged about 18 months ago. Lots of oak and hickory. I ran the 14" bar and the chain that came with it. I gave it three swipes with a file before i started. It definitely could've used a sharpening after four tanks. I cut about two cords total.

It really woke up about halfway through the first tank. It was like somebody flipped a switch. I'm not sure what this says, if anything, about the longevity of the saw. Most of my other saws seem to take about 5 or more tanks before you notice the power increase. My earlier comment about it not carrying rpms in the cut like my GZ400 are not true. It feels every bit as strong now. Fuel economy is not quite as good though. I attribute that to the strato charge design of the GZ400.

I really like this little saw. I'm glad I let you guys talk me into trying it. It is turning 12.5k rpms unloaded. I think this saw is going to see quite a bit of use in the future.

I will not go to the political forum, as I only lose respect for people and have to leave the site. I can tell well enough what people think in that regard, as it is seldom well disguised. Keeping it about chainsaws, stoves and firewood is proof there can be common interests among people who would probably be convinced they had nothing to talk about in this ever more polarized society.

I did not mean to literally go there, I was trying to put perspective on the ST debate...as I agree with you...I don't want this thread to be ruined either!

I just gave one of my buddies a earthquake and he is pumped about it! He wants to mm it and we are going to do that as soon as we get better weather to tune it in the cut.

I think it may be lean...11,000 is "supposed" to be the limit...but that may be wrong of you are running a 14" bar. Did you mm and port it?
 
Just checked my newest one out,145 compression. Fired the first pull,stayed running one the second. No need to touch the carb at all ! For now. LOL Got to fix that muffler !! LOL Can't hardly hear it run !

i can't believe this,,, you of all people john buying an earthquake :hmm3grin2orange::hmm3grin2orange::hmm3grin2orange: that is just to funny,,
i think we need to take up a collection and buy one to send to 056

Who is 056?

Is that your pseudonym? :laugh::laugh:
 
It feels better to act ind my mind like it is not true. We will never recover with the defecit and our debt to China. So quit buying things from them damnit.

geeezz,,,,, toilet paper even comes from china and so does that ipod,,cell phone and puter that you are using

Nope, not lean at all. It four strokes like a MOFO out of the cut and cleans up real nice in the cut. I didn't port it but it has a massive MM. I probably opened it a bit too much. I doubled the size of the opening in the brace and made a similar size opening in the muffler. I drilled about 20 1/8" holes in the baffle but I left the screen in place. It isn't obnoxious but it has a pretty good bark to it. I didn't bother pulling the base gasket as it is already blowing 160# of compression.

IMO only leaning it out to 11k would be leaving a lot on the table.

In about 10 years when China starts to regulate themselves out of the manufacturing business we will be longing for the "good old days" of cheap saws and TV's
 
I was second guessing myself about how high I have it cranked up. I suspect it could probably take another 500-1000 rpms but 12.5k is about where I like em. Still gives a little margin for error.

The funk on the top corner of the muffler brace is from my earmuffs. DOH! At least they were cheapies from HF. Chinese PPE for a Chinese saw:msp_biggrin:

You know; I'm starting to feel naked by only having 4 Earthquakes now

What happens if a storm comes or even a earthquake


:jester:
 
Guess i missed the cheapo earthquake wagon, $80+ now for one :msp_angry:

You can buy a brand new one from sears online for $119 with free shipping. That's for the 41cc version. IMHO they are worth every bit of that.

At around $40 it was like buying a bar, chain, scrench, and bar cover and getting a saw for free.

Please do so I can video tape it getting smushed in the undercut of a big tree.
