I tune by ear and then check it with the tach.

Wide open throttle speed
(W.O.T.)
12,650 RPM
This is what it says in owners manual under technical data.

Here are the updated specs for the Echo cs-400;

No wonder that is a little hot rod, check out the ignition advance, 34 degrees at 10k rpm...

Thanks Sharkey. That is very helpful to have.

Is the full service manual available?

Thanks.

OK, so the tach is on the way!
"
These my be dumb Qs, but the max rpm is that unloaded, like not cutting... and is there a diff. between 18" and 16" bar? the book specifies 16" but mine is 18"

It is unloaded. The size bar doesn't matter.

Thank you!

So is there a benefit to getting an aftermarket bar?

 I got a new chain, Oregon, without the drag links. I am working on a little race with some coworkers, but weather has been real bad here lately, cold and wet. No one wants to be outside in weather like that, so I am getting the saw as ready as possible. Both of my buddys got factory Husqvarna saws.

Ok, so I pulled the tach out of the package and when I placed it next to the plug wire...18888 was displayed while the saw was at idle. It is set for one spark per rev and I am going to source a new batt. Is there anything else I should check?
Thanks again
Luis
