Randy, I saw that same ridge on the top of the exhaust port in the EQ saws I got. I'm not sure what it's supposed to do: it allows a small portion of the exhaust port to open about 5 degrees before the entire port lip gets exposed. I used it as a guide when I was raising the exhaust port up to compensate for removing the base gasket.

Also, these saws just have a single ring piston and the pin is on the intake side, so you can make the exhaust port as wide as the metal allows.
 
I've been watching this ebay seller since Scott started this thread. The popularity of the quake has prices are on the rise, along with the shipping rates. :msp_scared:
 
Hey...you're a timber faller. We all know that you're just absolutely rolling in money. Every faller is. :msp_rolleyes:
Yea #### you, this is not the 70s...

Why is it,no matter what thread you're on, what site you're on, some tight-#*$, whiny, I have no life or friends, sad sack, has to get their panties in a wad and pee on everyone's parade? If you think the thread's stupid, why are you here? Post you're negativity on another site.:angry:

Damn man, you should probably attend some shrink sessions. You take this stuff way too seriously!!

that is the pic before i widened the port,, i have no idea the idea of the dimple at the top,, but you can see the post is small,,, i don't know the exact % that i widen it but i would say its about 20%

So are they using that "flange" inside to set port height and timing?

I know!!!!

At my limit on the price really. I should have bought more when they were $35.

Course could have been his plan all along, get the word out with the $35, then run them up.

Not that they aren't a deal at $45, but just not for me for multiple purchases.

(I say that and have bids on two of them......)

Great thread....very entertaining watching y'all have so much fun for <$40.

I think Randy is getting very intrigued. I bet he has been on fleabay and is already having arguments with himself about a purchase. A porting experiment for the expert is hard to turn down:laugh:

I admit I thought about it, but I really do not need another saw;)

I am pissed at this seller! he wont even recive my questions about sending to EU!!! :angry:

Oh well have fun with them.. I bet this is a great learning saw!

I'm going to cross post this here too:
Here's my attempt, somewhat more conservative:

I didn't mess with the upper transfers, but I did a little clean up on the lowers. I tried to direct that flow to the intake side runners:

The squish band on mine was a mess, with strange casting defects and two lumps under each side of the spark plug boss:

That concerned me as I'm removing the gasket, so I did a bit of sanding with a big dowel and some 220 grit:

It's not perfect, but it's better.

The muffler is next - still deciding how I want to do that.

My porting was also conservative like yours. I removed the base gasket and did a muffler mod, completely removing the restriction in the center baffle and opening the outer opening to about 80% of the exhaust port opening. My timed cuts were pretty close to the ones posted by others who removed a lot more material and opened the transfers as well.

Since the time on the cuts is so close, I'm thinking we're overlooking another common restriction, like the intake. I'm going to try to put a much larger air filter on it with a direct route to the outside. I don't think the airbox gets a lot of flow.

Any thoughts? Next would be a larger carb...

you know i can't figure is why sawtroll has been in here

He runs a search every day using the word husky, at some point this thread probably hit his radar because of the word huskyquake.

Well, it's only 38cc. I have not looked at the carb but that is on my list. However, the port itself is up against the piston opening and closing fast - it's a time & area issue, you are trying to uncover the port area quickly as there is not a lot of time to get the gasses in and out. Farther away where the pulses are smoothed out some you don't really need a very large opening area to flow the volume of gasses a 38cc engine will move - so large airbox openings are probably needed. I do plan to modify the a filter cover though.
 
you guys might love this guy but I don't

The following is my personal correspondence with the seller all I asked him to do was open a claim with Fedex, which must be done from the sellers end. He basicly told me to pound sand. Please help me by giving him bad reviews or stop purchses all together. Thank you my AS brothers. Im Keefer

The proper order of correspondence starts at the bottom and works up

Dear keefer19064,
You need to contact Ebay regarding this. -

Dear sellingitasis,
Hi,Fedex says they left it by the door. They never left it at my door. I have an electric gate at the drive entrance, and someone was around to recieve it. You gotta make a call to them people and get this straightened out.
Thank you
Keith- keefer19064
