    this is what I was referring to

      Yeah I thought that, there was posting as I was writing that I didn't see.

      I must admit I should do a lot more internet reading. There is plenty on PLASTIC CRANKCASE STUFFING.

But agree plastic used inside an engine, spinning and rattling would seem to have less of a life than the metal parts.

        I would expect you may have running issues if you dont replace that plastic part. Jetting may need to be altered as the airflow or pulsing of air thru the carb will change, there maybe slightly less initial suction available to draw fuel.

        The plastic part is NOT available separately and doesn't show on the parts fisch. It's an old machine the owner does not want to put a bunch of $ into it.

        I believe your machine is that old (and likely made W/O nearly as much plastic), but remember, this is a commercial machine, run HARD, EVERYDAY-ABUSED..

        The parts diagram (NO plastic parts showing):




        Worse case scenario, I'm out a little bit of sealer for the crankcase. Well worth the tear down just for what I learned..


        And 99Yam, I checked that air line from the crankcase. Once it reaches the carb, it goes into an orifice on the OPPOSITE SIDE of the needle /round diaphram.

          yes the piston displacement would be the same, but with smaller crank case area, I could see a faster exchange going thru

            Capt Solo (AKA "Performance 42"), can you please start a new thread and not hijack this one.

            __________________________________________________ _____________


            Opinions please.

            As these "stuffers" don't show anywhere, (even in the shop manual), and we know what they do.

            I'm concerned of this other side failing (likely, just a matter of time, then it is a "parts machine").

            Yank the other side, one less thing to blow up (as the other side already did), or leave it in?

              You could either run with one or none. Unless some tech at Echo can suggest a source, I see no other choice.

                I would leave the all out, since we do not see them normally.
                what is with the capt solo in the post?

                  Yep, I was leaning towards yanking the other one. Just a matter of time before that one lets loose.

                  It'll come out today, sealer shows up this afternoon so I'll re-assemble (or at least start re-assembly).

                  I'll post how it runs compared to the other...


                  Re: "Performance 42", it's Capt Solo" again, just under another name. (Of course he would hi jack my thread just to mess with me).
                  I've already reported him to admin, they can tell where that member comes from and take appropriate action.

                  If he wasn't so nasty towards other members (myself & you included), I wouldn't care.

                      Just an FYI, I removed the other stuffer. It's apparently put on the crank before the outer bearing is pressed on, then strengthened with the wire retainer.

                      Just for S&G's, did a compression test on the block (crankcase NOT SEALED but on, seals in and snugged down), spun over with a drill motor.

                      Got 150 PSI which is what my Poulan blower (very powerful engine I just de-carboned the piston ring on-below pic) has.


                      My customers looking for a used crank with the stuffers still on.

                      I'm curious as to how much the compression would/could/should/may rise...

                      Lastly, on another forum, they speak of the stuffers and its posted expect about a 16% reduction in power without them...

                        Just an update FYI (for the curious)

                        Machine was re-assembled and tested with a decent chain.

                        I did remove the other stuffer, so there are NONE in the machine.

                        I have an identical machine that I also ran today, I can't tell the difference in performance;

                        Below video IS the "stuff-less" Echo on my test log...

                          Lol a little baby saw!! She is running good by the sound of it...and cuts pretty good for small saw. That would be a nice saw for limbing after you got the tree knocked down with a bigger saw.

                          Glad you got it sorted out.

                          Where is your chain saw pants,boots,jacket,faceshield,hearing protection and whatever else OHS feels you have on??? I am reporting you.

                            Sounds pretty good to me.
                            You probably need to test on a "dynamometer " to actually see the difference. It seems a small performance percent, and maybe that is the reason they don't appear in drawings, perhaps suggesting they were introduced during the life of the drawing and maybe discontinued?
                            Love seeing consumer demonstrations.

                                Yep, it's a small "climbing, limb saw", It actually has (from the factory) a hook that swings in and out for the climbers going up the tree. (They hang the saw from their belt, running-bar locked).

                                It's really not designed for tree's as large in the video, just limbs..

                                I use that stump for every machine BEFORE it gets delivered (testing-that one passed!). A slightly lean tuned engine, WILL BOG during the test(with the load)


                                I DO use really good ear muffs for about everything and am wearing my glasses.. I was wearing my "G0ld toes" top of the line socks and Reeboks!

                                It was about 80F, kinda muggy this am (warmer than usual this time of year) when I took the video but am usually in shorts (except when riding the motorcycle)..
