Echo cs 490 porting

Ok, no spark at all.

I'm done, I would still call it a success. Even before the carb mods.

Ported with a 18" 3/8 lo pro setup I think it makes a great lightweight firewood saw.

Only thing left to do is see how well it handles 20" full size 3/8

I'd have to fully agree with your entire post.

I'd say a 18 3/8 would be perfect or a 20 .325. I'm glad you were able to make that saw run like it does. I'd still say scribe ur timing key then put in a vice and file one side about .020 to .025 of the flywheel half and try it if your not happy then flip the key around and youl be at stock time again both my echos are advanced and they have not burnt up yet. My piped echo had about 4 tanks ran through it Saturday by many ppl including me. Some let it piss rev some pushed and lugged it and others let it self feed and didn't se no sign of over heating

hard dry pine

I need to get a video setup again.
My 500p with 3/8 full comp on a 20" pulls well in the Doug fir round I tried it on.
Winning races? Nope. But it's my truck saw now.

20" 3/8×7

Same bar/chain.

While not the fastest setup, I was mighty impressed with how it pulled it. Seems the more fuel I get through it, the less it wants to clean up in the cut.

It is going to get a 18" lo pro bar, because I do not like the way the full 3/8 acts while limbing. Plus I just bough a couple nice lo pro bars. Lol

 

[Red97]

Just cause I could.

Even oiled it well.

Full size 3/8 skip.

Wow.

What size bar is that?

Did you adjust the oiler?

I think you peaked a lot of interest with this last Video.

That is a 32"

Oiler was set to max could just sling some off the tip, chain stayed cool.

Figured if she won't rev, let's see what it will pull...

(Edit) think I'm gonna grind the full comp chain tomorrow, an see how well it goes.

Lol, wish I had a big oak log to really test it.

It was within 12 seconds of the fresh stock 288 I had, same log, 32" bar and a full comp chain same grind specs.

And 18 ish seconds from my ported 371 same setup.

Impressive to say the least. A 50cc saw pulling a 32????

 

[Backtroller]

That saw pulling a 32" bar is awesome! Never would have thought it could have done that. I didn't think balsa trees grew that big (jk).

Curious to see what you can do to the 421.

The Lil saw that could. Pull that big bar as fast as the small bar. Kept about the same rpm as other vids you did. True work horse you built up. Hell I'd run that saw on a job site without question

Thank you guys, it shocked the hell outta me too...

That was a ol cotton wood tree, very soft but can still load a saw good.

This is the same log with my old ported 371 and a 32" fastest time I have through that log.

How can this be true???!!! SawTroll has made a career out of promoting Echo's "low power" specs.

Well if think most realize that there is more to cutting then just the HP ratings.

Saying things like that would get you attacked on AS. I'm liking this OPE site...much more Echo friendly place.

 

[CapitaineHaddoc]

That's impressive for an Echo, especially for this model, a homeowner saw.

There's another fun vid with a 346 and a "32 bar,
