    JEREMY, thank you very much for this GREAT VIDEO.
    I have a Stihl KM 110 R that requires a rebuild. Ive never done this before, but I think I learned enough from your video to be able to do it. I am buying a new 130 tomorrow, so the 110 will be a winter project.
    Again, thank you very much.....

    I am a stihl mechanic if you use aftermarket piston and cylinder on some the coating comes off that is why thay are cheep if you get a oem piston and cylinder it will be about 300.00 make sure you do a psi and vac test on it

    Thanks for the great vid, I've got a 420 on the bench now. I believe it also needs a new top end , I've gotten the saw to run but when I switch the top selector from start to run the saw dies . Any thoughts ?

  • @andrewsrenson1212
    @andrewsrenson1212 8 лет назад

    had a makita one of those that i had a good run with for about four years with punishing concrete cutting...no secret that it ran faultlessly due to a strict wash & clean after each use.
    i dislike maintaining power tools but i absolutely hate it when they break down & the waiting and expense of repairing them

  • @vanreliant5584
    @vanreliant5584 5 лет назад

    When cutting masonry always use the water jet and diamond blade, wet mud doesn't fly about and get sucked into the engine. The dust from dry cutting easily reduces engine life by 3/4 you need deep pockets to afford to ruin tools needlessly.

    Hello mm1 im working on a TS760 that I can not make run like it should. Before it was loosening power when I tilt it down without touching the concrete. And I replaced the carburetor so now, when I run it on full throttle revs up and down. Any ideal of what it might be??? Thanks on advanced

    Can you please show me how to strip a TS400 down and rebuild it because I am trying to learn but there's no videos on this model. It will be very much appreciated and I think you will get lots of views because there's still plenty of people that think the TS400 is the best model Stihl did for the cut off saw. I need to know all about it and how to put a pot and piston in, also I would love to learn how to put a new crank and crank seals on this saw, now that would be extra awesome. Thank for this video anyway I think you did a fantastic tutorial.

    Hi mate good video,
    Would it be good practice to change rings before total failure when your machine has compression issues starting?
    Thanks

    hey @THEMOWERMEDIC1 whats up! so i just bought a top end kit for my TS500i which is a fuel injected model.
    There are no videos on them but i am going off of your video cause they are similar design. Your video is great but some of the small things i have questions on. do the rings have a up or down orientation? i know on cars there is a dot marked for position.??
    do you have any advice on the fuel injected model?? this particular saw has ALOT of concrete dust in and around it. thanks man! i liked and subscribed btw!

    when you put a new top end on you didn't replace the cylinder head gasket and how about doing a presher test to see if the crank case is not leaking don't you have to do that when you do a rebuild like that

  • @shaunkeen5821
    @shaunkeen5821 8 лет назад

    Jeremy I know they are similar but it's the little things I am struggling with, like the carb is different and the cylinder head isn't screwed from the bottom, and I want to learn how to break a crank and change the seals etc. There's no video on how to fix a ts400 when there's no compression, and there's no video on how to do anything to do with the crank and splitting the case. I just thought it would be a good idea if you could show your skills on how to fully strip a ts400 and put it back together because I know there's thousands of people out there that would love to learn about them. They are still the best cut off saw Stihl ever made and there's hundreds of thousands of people out there that still use these saws and like I say that a lot of them still think the ts400 is the best saw to have. My mate sells after market Stihl ts400 parts and his business is booming so I know a lot of people would benefit watching one of your videos, but even better would be the ts400. Thanks for

    Excellent Job. The aftermarket cylinder availability has just exploded. Whether it be Woodland, Tecomec, Meteor, Hyway, HLS etc. Weedeaterman has been ranking the a/m kits for reliability if your interested.
