To Those with an Echo CS-490

[crazyduster]

Hello I'm New Here
I had an Echo CS-490 that was stolen and I really liked it. I bought another one my 1st one started cold 2nd pull burp every time. My new one takes 7 or 8 pulls to burp cold.
How many pulls cold to start your Echo CS-490
Thanks in advance.
Mike

Welcome to the site. On most all saws the carb needs to be adjusted to make it start easier. Was the carb adjusted on the new 490 you got? The L needle needs to be set a bit on the rich side to get the saw to start easier when cold.

No both are factory. Thanks

Try setting the L needle a 1/8 turn counter clockwise before cold starting the saw again. The Echo saws are known to come from the factory set very lean so they pass emission standards.

I'll try that thanks

My cs-520 is cold blooded, it takes it time to warm up when it's cold outside. Worked pretty hard yesterday on some very hard Locust

Echos can be a bit funny with the factory limiter caps on. 620 definitely needs to be tweeked from factory

 

[crazyduster]

So far so good. 2nd pull burped and running.
Thanks

Have you removed the pea shooter tube in the muffler? Removing the tube makes the 520 a whole different chainsaw. A very noticeable increase in power.

Mine was tuned in at the dealer, but it’s two or three every time.

 

[leecopland]

2 or 3 what, every time?

 

[Tallest]

2 or 3 pulls.

 

[Colt Marlington]

Seems like 2 or 3 choked and then 1 or 2. But I only use it once or twice a month, so I could be off a bit.
It starts easy regardless.

Same with mine, 2 to 3 then let it idle, hot, 1/4 pull.

3 to pop one to start after, at least down to 20*. Never tried when its colder then that.

We'll saw some day it's in the single digits.

Is this a difficult process? My 520 is the first pro saw I ever bought and it's been so flawless that I'm almost afraid to mess with a good thing. I got it before I learned about tuning. Still has the limiter caps on. All the saws I buy now get the caps pulled before I fire them up. A bump in power is always a good thing. I'd be more interested in the mod to help the saw run cooler.

May be a dumb question but without the limiter caps on wont the screws move when running it?
Thanks

Most carbs either have springs or rubber grommets under the head or tight to the shaft that prevent them from turning after the caps are removed. Some say to reinstall them but for myself I don`t if there is either of the two above mentioned devices that will hold the screws from turning. If I could not discern if there was something there to prevent them from turning then by all means reinstall them after final tuning.

I've never had a problem with them moving. Some guys cut the tabs off and re-install the caps but I don't.
