dissecting an earthquake chainsaw

i think we all have some serious issues for buying so many:hmm3grin2orange::hmm3grin2orange:

Okay, I don't have a video of my cutting or anything fancy like that, but I can tell you (roughly) the times and gains from bone stock to muffler modded and ported. I posted my porting pics somewhere back there and I didn't get really radical, just mostly opened the exhaust and let it breathe. I only opened the intake port, exhaust port, opened the muffler and removed the base gasket. I didn't change timing, change the carb, use a different chain or anything else.

38 cc Earthquake with 16" bar / chain on 10" oak, stock with one tank of gas through it: 17 seconds

same saw as above ported, mm, no base gasket and 3 more tanks on the same 10" oak: 13 seconds

same as above after I hand-filed the chain and lowered the rakers a bit: 12 seconds

I don't know if I dulled the chain as I was running it the other day or if it's just crappy chain to start with. I used the b/c supplied with the saw.

I think there are significant gains still to be had. I know the piston can have some weight taken off and give it more duration on the intake, I know I can still enlarge the intake and exhaust much more than what I've done already. I didn't spend a lot of time porting and polishing, just opened it and smoothed it up a bit. I'm very pleased with the little saw and I'll see what other improvements can be made as I use it.

Attach a little bottle of NOS to it. Or start running nitro!:hmm3grin2orange:

clogged impulse port/line or hi-jet on the craftsman for sure, it usually happens when they sit for a long time.

Just check I'm still top bidder on my saw's

me too

I'm still top bidder on two of them. Less than 8 hours to go, hope my bank account can handle a couple more tremors. :bang:

 

[diggers_dad]

Aftershock?

Tremor?

Shake N Quake?

Shaky?

Aftershock

First one I saw was Aftershock it is :jester:

Maybe I'll get a custom sticker for mine when I finish all the mods. Since you liked "Aftershock" I guess I'll go with "Tremor".:hmm3grin2orange:

[poorboypaul]

HA! Just put bid in for the last unbid one. Bought 3, sold one, and haven't even cut with one yet. Too cold and too much snow! Gonna mod one when I get some space cleared to be able to work on some more.

Let's not bid against each other, my E-buy handle sounds a lot like my AS one. After all we have to save money to pay our recent tax increase.
