8 pin or 7 pin echo cs 440evl

it has torque but seems a little slow a muffler mod improved performance but i thought i would ask if a 8 pin would speed it up a little with out compromising the torque it has.
currently it has a 7 tooth spur .325

I don'tnt think it wants any part of an 8. The older Echo saws were not fast....but they were good workers.

its a good saw but i was only curious i might move towards a base gasket delete next.

I honestly wouldn't put much work into it. The EVL saws have a weak ignition as they age and are NLA for the most part. I really like my old Echo saws too...but I would just enjoy it the way it is and be happy.

i got NOS ignitions parts in the house for it.

well jimmy i could do one thing and ditch the worn spur for a nice rim drive set up.

Yes you could.


Let me explain myself a little. I have a 750EVL that I have known since new and a 452VL. These saws have cut everything we needed on a small horse farm growing up. I found ASAP way back when and fell into a spiral of CAD. Fast forward and I come into a Poulan bow bar that will fit an Echo. I ditched a 3/8 -16" Windsor and put on a 14" bow and went to .325. Now it's a neat looking setup, and fun for 5" and down, but that's it. I thought going from 3/8 to
325 it would have plenty of grunt; it doesn't. Saw runs a 16"-20" 3/8 burried all day long no problem, as that's what it is designed to do.

By all means try out some different setups. I have found the older Japanese saws ran pretty good for the time but there also isn't much left to be found in them.


One thing to check, make sure your throttle opens 100%. A bunch of Echo saws make from the factory only opening 75-80%. You were to run it 10 hrs then return to the dealer for a retune and they would tweak the linkage for 100%. Lots of people never went back.

Interesting insight on the factory throttle setup. My 701 came to me like that. Good to know.

The only 8-pins I run on my old Echos are on the 70cc and up models. Although they pull well when put to task, there isn't too much to be gained with cutting speed in my experience. They do have consistent and ample torque. I do have a fondness for the old series though. But, mainly for their robust design, unique sound and smoothness given the vintage. I can attest to the weakness in the EVL ignitions. Lots of nice 702/750's sitting out there with no spark.
