You should see what a crank bearing or rod bearing does to a piston.With a piece of metal bouncing around in there should keep the carbon build up under control.![]()
Just recieved from UPS today . A Shindaiwa 600SX I ordered online 24" bar also . Same saw as Echo CS620 . Two rings on piston etc . Of course haven't ran it yet . I felt like I got a good deal .So I bought the Echo CS-620 and ran one tank so far.
Feels heavy when hauling to the cutting site, but well balanced when cutting with the 24" bar.
Partner are/were fabulous saws. I bought one that had been run over by a truck but sustained only minimal damage - then used it for 15 years before it finally went to the big crankcase in the skyI love that nobody knows about certain good saws out there.Had to put in another piston today after a tear down to see what was up with the stuck ring.
These saws were way ahead of their time IMO. 1984 Partner 5000 plus and I had a 1979 5000 open port that was strong or stronger. This makes about 15 or more of these I have had now. Keeping a few back, well maybe.
I really like the guys that pass on the Poulan Pro 325 which is a Partner 5500. :licking:
Just a few.

My Echo 590 is terrific too - heavy but effective. Here in OZ we are cutting extremely hard timber but as long as the chain is sharp, this saw hardly noticesSo I bought the Echo CS-620 and ran one tank so far.

I will say it is a world of difference faster on the bigger Ash trunks than the 490.
And I felt less worn out while using it.
Good power, didn't bog down in the rotted core of one trunk like the 490 would.
Noodled a smaller, 2 feet long by 10" or so Ash crotch, fast, and NO clogging like the 490.
Now the 490 will be used for smaller stuff and as backup.
I might even try and get the old craftsman 49 cc working, not sure what is wrong with that yet. Could be carb or coil.
Didn't see spark, but have not spent any time with it.
Of course it won't run right, it's tweaked to the left in relation to the handleIn after falling out of a tree. Messed up and wont run right.
