Title: Echo CS 900 EVL
Post by: ambull01 on November 11, 2015, 12:05:49 pm
I'm about to buy this saw for $150, or hopefully a little less if I can lower the price. Anyone here have this saw? I'm going to need a lot of help putting this thing together. It's supposed to be apart. Compression is a bit over 140 according to the seller.

Just read there's an after market P&C for the 1200 I think. If the P&C is trashed, anyone know if I can install a bigger P&C or where I can get a replacement? Also, other than putting a higher pin sprocket or whatever they're called, anything else I can do to improve performance (i.e. squish, remove gaskets, etc)?

@Al Smith ran one at a gtg and said they had some grunt to them I recall.

Never ran one myself and only seen them for sale local a few times.   The price is right though. Let us know. 
$150 for a 90cc  is a buy all day IMO

So a brand new piston is only $26!? Does that sound too cheap too you? Damn, I may be able to keep this saw running forever.

I'm running a $15 aftermarket 066 piston.  Looked fine wouldnt recommend the rings or circlips that come with the afm kits unless meteor rings = caber. 
But I am running them all that came with the $15 piston because it is mine and I know what to watch for. If it happens it happens but I wanted to test one and see.

Anyone have specs on the piston? Like crown to pin center? Looks like a 54mm 2100 piston, sorta.

I'll show what I passed on yesterday and day before. Now that it is sold. Very cheap too. Didnt want to drive almost 3hr round trip.
Wonder if someone here got it. Was told they bought it many years ago and no longer need. Echo 900EVL
Was to heavy for me PHO so I would have just flipped it.
