Just another junk chainsaw

Wish I had a echo 620 to test with these ported and stock cylinder 359's in future.
Already know how the 590 is. Owned and sold even after muffler modding. Like to see what the better port timing and less vibration of 620 is like.

I know the ported one pulls 24" 3/8 like a beast rip cutting already.

Got the 490 going, a little carb cleaner and changed the gas.
The saw seems picky, as I emptied the tank into my blower, and it started right up.
I had to adjust idle, was going too fast, but that's not a new issue.
Purrs now and idles like it should.

Run ethanol mix? Dia's could be getting stiff.

Mostly canned mix, especially the last few batches for the 490
I do run e10 with stabil and red armor oil, have not had problems with any other engine with that mix. Blower, brushcutter, long hedge trimmer etc.

The 620P only gets canned gas, too many Ash falling to even have a slight risk that one won't start.

Seems to be running fine now, if it does this again may look at the diaphragms. Saw is about 7 years old and has quite a few hours on it but looks pretty clean. Sprocket not too worn, but showing some age. on my third/fourth bars (18" and 20"), retired a few chains past filing. So I'm sure it will need some work on it soon, but it's been dead reliable until this hard start.

Dont care for the echo 2511 caps. They want you to use the T handle. I call BS.

577878603 T435 caps in normal ending on 1 and flip caps work ending in 3.

Both saws got a good workout today, on their way back to get cleaned and the chains sharpened.
The dead Ash is rough on chains when it turns from solid to powder in the trunk.
More work to go, lots of firewood to make.

490 do fine?

Have you muffler modded that 490 at least? Echo is so bad and detuning them using mufflers.

Stock 490 muffler is even worse then 4910 501 stock.

I have a new exhaust cover ready to go, just need to find the time to get the old exhaust off.
It is pretty well stuck on from the factory.

Will let you know when done, need to clean the screen too, sure that's not helping the HP.

Toss that blame restriction pipe they put inside too.

Open the front of stock deflector and it's all free for nice gains too.

If I ever try something else on a 2511 besides the Egan pipe. It will be the cnc version from a member in my CRG from NY.
He has 2 versions and like them over wcs version.

Bigger pipe outlet and a smaller one that reminds me of the open clone muffler size.
