Ported a Chinese Chainsaw Pics and Video

[stinkbait]

I have already posted these pics and vids in the earthquake thread, but I wanted to get them all together. And I'm sure that there are several members on here that try to stay away from the earthquake thread.

Got the saw for $35 just like it sits. 38cc of raw power.

Saw has metal crankcase.

It looks like a nice, cheap toy.

What are the issues that buyers are seeing when they buy the non-running saws?

Is that long slender slot a transfer???

Is that hump-backed chain?

Mine had never had fuel in it. Fueled it up and it cranked on the third pull. That long slot is the impulse port for the carb. the chain that came with it was semi chisel 3/8 low pro. The after video is running 3/8 chisel.

Very nice work. Nearly a 50% gain!

Thanks! Just the port work alone gained me about 25%. The rest was gained from the chisel chain.

That Stihl lopro full chisel is SSSWWWWWWEEEEEETTTTTTTTTTTTTTTTTTTT stuff. I have it on a S25DA (7 pin), S25CVA (7 pin), and a PP295 with a 7 pin rim and soon to try a 8 pin. I likes it......

Uh, that "red oak" is black cherry. Probably tougher, actually.

This is not 3/8 low pro chisel. This is full size 3/8 full chisel chain.

That isnt bad looking work at all, and you have the gains to prove it. The fact that it is pulling full 3/8 says something, atleast to me. Cant beat these saws for the dough. I bought 3, heck the bars and chains were worth that.

Good work

Looks like the next race saw series. Once these get all built there will be a WT vs. Earthquake GTG!!!! :msp_w00t:

 

[millbilly]

Using two different chains and bars seems to make everything void. Dosn't show me anything. I appreciate what you attempted to do but it dosn't show anything. You gotta run the same chain and bar.

This is not 3/8 low pro chisel. This is full size 3/8 full chisel chain.

Did you change the drive sprocket? I actually like LoPro so i don't intend to change it, but I was curious as in general 3/8 LoPro and 3/8 are not completely compatible.

it has a 2 piece head just like a "pro" saw,not a clam shell . interesting.the japs are getting smarter.
