You just need to shave half the key (around .025") which should be between 6-10 degrees.

No need to go more.

Make sure you shave the correct side so you get advance, not retardation.

Thanks.
To advance it the flywheel needs to move ccw on the crank right ? It's been a while since I've played with timing on anything.

Yes, ccw (but check by slowly pulling the starter and watching direction).

A cw rotation, you would remove material from the right side of the key. A ccw rotation would remove material from the left side of the key (as you're oriented looking at the flywheel on the saw).
 
It may have a cast key too, never been in one.

As far as timing -- a key is there mostly for indexing, friction does most of the holding.

Advance it.

Test

Drop the jug, cut the squish, and port it.

Test

Timing advance is easily reversible.
 
Does anyone know whether the Echo models discussed in this thread are made in Japan or the USA?

I see that recently Echo has been making many of its products in the USA, but not sure if that is the case with the 59.8cc saws.

Awesome news that a 3rd big player is now making 60cc saws with magnesium case and outboard clutch! Really old Echos were like that- I own one and like it- but then they made all outboard clutch saws for a while again. No thanks.

Edit: Meant to say new Echos are inboard clutch

Every Echo I own was made in Japan. I consider that a GOOD thing.
 
Mine all say parts from Japan, I don't know where they are assembled but I would say Japan.

ALSO, for all the Echo lovers, I may be parting with my 620P (was a 620PW but got a new handle...) with dual port muffler and deleted base gasket. Runs great just have plenty of saws and saw projects right now... so thought if it went to anyone might as well be someone in this group... have 20" Oregon or 27" OEM bar for it... if interested please PM me with a number you like and lets see if we can agree :)

600 ran like a top on my trip up this weekend. Big old 4900 out there for play only.
 
"Awesome news that a 3rd big player is now making 60cc saws with magnesium case and outboard clutch!"

590/600/620 have inboard clutch.
What is the stroke of these?
There is no small spline clutch drums for these is my impression so if you run 0.325 only 9 tooth choice.
How much longer until they offer a stuffed crank version?
Is the vibration and sound data out there?
Are these 300 hour epa rated?

Thanks
Fran
 
300 hour EPA and 590 comes with spur sprocket the 600 and 620 come with 3/8" typical rim sprocket just like a Husky 372 or Stihl.

They are all large mount bars, not sure why anyone would want a small spline clutch drum...
