Little bit of this and a little bit of that...

[Red97]

Been working on this for a while. Getting to the 40% stage figure I could share before I lose all my pics.

Echo cs 8000 with a 395 top end. 38mm stroke 56mm bore.

Stock echo rod on top. 70mm
Honda scooter rod on bottom 80mm

 

[Red97]

Big end of scooter rod was too wide. Surface ground it to size. Then had to source the correct size bearing.

 

[Red97]

Stock 8000 crank right new rod left

 

[Red97]

056 magii piston dome cut to a pop up. Netting .027 squish no gasket.

 

[Red97]

Cylinder on slight trimming to get the covers on.

Gonna have to get creative with an intake block/boot. Stock 395 boot is too long. Plan on running a wj carb.

This thing has some wild numbers for 94cc. Gonna try it as is then port in stages.

In, 94
Ex, 107
Tr, 120

Cylinder extension had to be turned down a bit in diameter to fit the echo case. The ex side bolt holes lined up perfect, intake side needed to be opened up a bit.

Both saws share a 13mm piston pin (cs8000/395xp)

Got the 395 jug to fit the echo case, try the 395 piston it is .220 squish.... Not good. Couldn't find a taller piston.

Thought the rod was shorter on the echo, not the case. Both rods are 70mm.

So I press apart the echo rod, of course it has odd bearing sizes. Only rod I could find was 10mm longer... luckily the 395 piston is about the tallest piston made lol. 066 BB piston skirt wasn't wide enough to cover the ports, so I try a 056 mag2. The dome just kissed the band. Hence the pop up.

Parts list so far

Echo case,covers,crank.
Husqvarna 395 cylinder, am 372 muffler
Stihl piston/pin bearing
Honda connecting rod
Poulan wj carb most likely

And a whole bunch of extra/scrapped pistons,cranks,rods

No I haven't. Sounds cool tho.

 

[Time's Standing Stihl]

Can't wait til it fires up, I'd love to run it someday

 

[Backtroller]

It would be even cooler if it sounded like a Honda Spree when it runs.

Well it is a good dust collector... Stalled out a bit. Intake side is going to be very tricky to fit in that little carb box.

Echo 8000 use a hda carb, borderline enough carb for 80cc let alone 94. Wj kind of fits the carb box.

Then I got a bit side tracked with the 730 hybrid, that basically fell together compared to this.

I'll give it another go eventually. May end up a naked cant saw, but it will make noise one way or another. Until then it's got a cozy spot on the shelf.
