Ron is out there buying the newest 70cc saws and here I picked up some old dinosaur 70cc. Echo 702EVL 70cc with 660 pho weight :o

As traded in. Cant believe this thing had a 3/8 8 rim on it with 24" bar. No bar was included but he told me that is what he ran for bar.
Dang she sounds and runs good. Cant wait to see what she does in the wood.

Looks as though it has more barn rash than usage scars? Just someone's firewood saw?
-
That old thing should pull the 8 tooth with no problem.
-
I'm willing to bet that saw will clean up pretty nice. ;)
-
It has some kind of paint spatter but it wiped up pretty clean.
I put a 7T and a 16" on it to test. Holy cow these things run good. 8T will be going back on. ;D ;D ;D ;D

Determan is your local stocking dealer. The distributor is in Columbus

FB friend looked up the echo info I was looking for on the 702evl
Was made in early 1973 to 1974, 3000 or so which is not many.
-
Cut4fun had the 702 out again on Friday.
Used a 8 pin rim and a 20" bar
Was run in a comparison with a Dolmar 6800. Though the two chainsaws are close in size. the Dolmar runs at a lot higher rpm and uses a 7 pin rim.
So the Echo 702 is a torque monster?
Anyway, to run both saws, the Dolmar 6800 ran a lot higher rpm but to try to observe how fast the bar was going through the log - it was about the same with both chainsaws.
Either chainsaw would be a good one out in the woods if you needed a good 20" chainsaw.
The 702 is large, dimension wise, but is balanced well. Not a bad chainsaw at all. Also the Echo is more than 20 years older than the Dolmar 6800. However the Dolmar 6800 is a remake of the Dolmar 116Si & 120Si which were improvements on the original 116 and 120 etc. So the designs were not really so far apart.
-
this is a very nice saw you got there !!!
-
That 702 is more than 30 years old :) I loved them when my dad had a room stocked full of them. Bob
-
echo nut could you believe parts are still available for this model from few sources
-
Whats the longest bar that one could use comfortably on these 71cc saws?
Guy before me ran 24" and 8T and yes it does pull 8T fine, I was :o. I tried 7T and shorter bar before and went back to 8T.
Thinking 7T and longer set up now with full skip.
-
24" I got from John 8)

I'd love to run this one. But not all the parts were in the basket.
Missing oil pump guts, muffler cover and decomp bits.

I've wondered that as well. I know the oil pumps are generous on these saws. It is a matter of torque after that I guess. In fact the same pumps were used on many of their saws all the way up to 1001. Specs peg that max output of that pump at 18cc/min at 6500 RPM. Plus you've got manual. 28" or more with skip, I bet. 1001 has the same delivery rate specs as the 702.

Great info. I did not know this and thanks for sharing.

67L36Driver - I don't know if this will help you (see figure 2, attached file). I want to say that the pump for the 750 is common and you might be able to source out one from another model? I have never had mine out to compare it with the 452/702/. But if it is the case, 451/52 can usually be picked up for pretty cheap. Unfortunately no decomp there though.
Cut4Fun - Perhaps we can put this somewhere?

Could make it it's own thread to save here too? Just make the heading the links name. Echo oiler handbook

Thanks Hogwood. Gives me more to look for instead of just the 750.

I'm going to get stupid and put the 36" with full skip and 7T for a go later.
Bar off the yellow 81cc onto the older orange 71cc. ::)

Modified Mark sent the oil pump out of a 602EVL. Seems to fit fine. I can get it to pop on a prime but need muffler for it to run.

Howdy, looking for a part number for an echo cs-702EVL falling spike.
Thanks!

Pics uploading to photobucket.
This saw is very very lucky to be alive. :o
While pulling the old muffler off that had been tack welded and 1 bolt put all the way through with nut on back side 9to hold together).
Somewhere along the line the oem welded on nuts on the base had come undone and 3 of the were found inside the muffler.
Old muffler
