Echo CS440
« on: November 15, 2013, 04:25:05 pm »
This new to me 440 starts but wont idle.  I cleaned the carb and replaced the fuel pump membrane to no effect.  The H&L needles have tamper proof fittings and I did try to tamper with them!  The saw has not seen much work. 
I also could use an 18" .325 bar for it if anyone has a spare.

You NEED to adjust the carb on a new saw. If you havent adjusted it properly, thats usually the whole root of the problem !

IMHO, pull th elimiters, adjust the carb in the wood, and then see how you like that saw !!

Is this your first echo?   your first cs-440?   I have one and really had a good time with it until I had a "lean running" issue.    Don't have a clue what your problem is, specifically, but generally, that carb, with it's limiter caps might really contribute to the madness.  Good luck with it, and happy cutting when you get it running right.    I enjoyed mine, and will be doing the repairs to get it back into shape, because I feel it is worth the effort to keep it.
    It has the screw in the front, below the muffler, to adjust tension on the chain, make sure you keep a good eye on the chain tension, it's not the easiest to keep adjusted, but if you don't your chain WILL jump off.   
    I have purchased another saw (different brand, used, and a step up in power) for the bigger stuff and some of my "all day" cut-fests that I have, but the Echo has been really a good one.

Here's a question.   How hard is it to actually remove those plastic limiters off the carb adjustment screws?   The space is very narrow to get to them to adjust them in the first place, should I just go in there with some needle nose pliers or heavy hemostats and just rip those orange plastic pieces off, or is there a better, less destructive way?   I really want them off my cs-440 as well, since I already burnt up my piston/rings from it running so lean, most likely from "over 10% ethanol" fuel, with some emulsified water in it, that I could not adjust (the carb) for.    Thanks for the help everyone, and good luck with your saw.

Oh heck, there I was talking up my saw for you, and just read the thread on the 550 where you mentioned that your 440 was going to be a "repair and sell" saw for you.   well, like I said, I like mine.   It came stock with the 18 inch bar/chain and I have never changed that.   Probably be underpowered for a 20" set.
    The big things I disliked are...   disappointed in the chain choices at general retail outlets.   The place my saw was bought at only had 1 choice for a chain for it.  That's not really a choice.     And they do not carry the air filter for it.    Online parts at "echo parts" (I think?) has the air filter at $20.00!!!  WHAT?  That seems a little out of place to me.
   Well, I am stepping up in the world, and going with a more professional saw for the heavy work, and have found my way here to you good people, but I will be keeping my echo as my back-up, and for smaller work.    So, good luck fixing and selling yours.   I hope you find it a good home and make a couple of bucks.

The limiters on this saw have been designed to defeat those of us who would remove them.  The usual orange limiters are covered and surrounded with another piece of material which stops them from being removed. That piece in turn is surrounded by a metal wall, part of the carb body.  I'll try to get a photo of it.  I guess if I had a Dremmel I could cut off the surrounding metal wall that contains both the limiters(and H&L needles) and the other surrounding piece but it would be tricky not to damage anything else.  Actually I just remembered that I have a knock off type Dremmel tool which I will try.

I'll post the results.

I use a fine threaded drywall screw.
Screw it into the center of the limiter and keep tightening it untill both th elimiter and metal retension plate pull out.
Easy-peasy !

If you take a close look at the side of the carb, you will see two notches that are present on the outer plate that holds the red caps to the carb.  Use a piece of wire or a magnifying glass and turn the cap to the left until the red stop shows through the notch.  Insert a drywall screw into the center of the red cap and turn it in clockwise.  The cap will slide right out.  Once you get them both out, use a drywall cutter or knife to cut the tabs off the side of the caps.  This will make the needles fully adjustable but you will retain the caps to protect from vibration.

 Plus it's a lot easier to use a screwdriver with those caps in place.  One tip, a bench grinder grinds those tabs off real easy in about 2 seconds, I leave it on the drywall screw when grinding them off.   Steve

Damn I didn't notice that you could line up the red limiters to the slots.  I used a cutoff wheel on my Dremmel copy and cut off the surrounding metal.  That got the limiters off and after adjustment the saw runs great.  My only worry is that without the limiters and surrounding metal the needles may vibrate out of adjustment.  Of course I can put the limiters back on but not sure if they will keep the needles where they are set..  Me bad.  Should have waiting for the advice here before going ahead.

Thanks for the input, always welcome
