Ran my 70cc echo's today.

Yeh, I can wait for the new release....

Hew haint foolin me. Hew cant wait tew see how much gooder yours is than the echo factory saw!

 

[hseII]

I would like to think they used the 37.x stroke of the 590-620 along with a 50mm bore



That makes 73.x cc just like mine. Wonder if I can get some royalties?...

I tried to put in a good word for you. [emoji1787]

Just hope they went long stroke for future looking.

Appreciate that.

Maybe echo will reach out.

Maybe I can shine mine up and make a new vid become YouTube famous. Then they would notice

Thanks

Reminds me what comes on the 400 and the 6700 I had. I like that set up. But I would use a outwears prefilter if I ever ran one like that again.

It’s simple: I like it.

Almost like those AM versions on the larger felling saws of the 1980s-1990s PNW.

Joe you see where 45 is on 620. I am guessing bore? See the 50 on 73. I maybe reading the whole thing wrong too.

I cant get a 37.x stroke to come up with their 73.5cc shown. I give up and will wait to see.

That's a standard bar length in centimeters.

Filter dudes can go on and read this openly available stuff from 2015-2016:

It’s gotta be either 49x39 or 51x36 if I had to guess.

That APP is so Tek Nickle!

Here's hoping for 49x39.

I already got 50x36 52x36 54x36 covered. Hope theirs isnt 51x36

Would be easier to keep all 36mm pistons on hand. Lol

I'm gonna guess something like this.

Prob the same bore/stroke as that new cut off saw....
