@warbirds3339mike i used to live near Timmins 10 years ago, grew up around there, you probably drove by my place LOL, now i live 5 hours south of there
As a Mason of 42 years, I can confirm they don't last. Mostly due to not replacing air filter regularly and wrong gas mix ratio. When ya have 8 different guys using it, this happens. That said, they are tough little Saws, and with proper maintenance will last a while. Just the nature of the beast. Nice video. 👍👍
Clean Air Filter Clean Air Filter, Clean Air Filter, Clean Air Filter, Clean Air Filter, Clean Air Filter, any internal combustion engine that operates in a concrete dust environment needs to have the air cleaner serviced after every use....or just buy new saws monthly
i just rebuilt mine with all new kit everything and on startup it smoked but i thought maybe for the oil i put on the piston and rings and head not much i let it run for 20-30 min at idle for breakin and it smokes badly on the rev up .......took it back apart to check the rings and head all looks good comp test at 87 -90 no leakdown after 10 min what do you think could be the issue
i have ts420 and its cranck shaft threaded portion brokedown ( pull cord side ) what can i do because i donot have any option to assemble puull cord as i cannot tight cup with any thing
@@donyboy73 so everything is looks good when I pull out the spark plug. The pool cord goes fine. It’s easy it’s a it’s good but when I put the spark plug in the pool cord just is not normal. It’s not like coming all the way up .very hard to pull.when I trying to pull it hard it just doesn’t happen I’m suspecting of the bearing or the crank shaft .
Hello! Im working on a stihl TS760 cut off saw. And when tilt down to start cutting loose power. Anyone have any idea of what might be wrong with it. Thanks in advance
Finally an informative, concise and easy to follow video The announcer is easy to understand. I wish every video was this good. Even the camera angle was perfect! Bravo!
Dony I sell Warbird Books with all documentation, mostly for the large radio Controlled Modelers who buid the warbirds like the originals. They have very large weed wacker engines and larger so no the models are up to 100 pounds. I will be selling at the Labanon Pa Swap meet the second saturday in March if you are in the area.
Dony You are way up there, a little bit more to Hudsons bay. How are the bears these days?? and the Moose too. we left that area and came down to Algonquin park a place called Hay lake Lodge...Probably gone now, it was rum By Gorden and Cora Palbeski. Mike
I have a TS400 that seams to run fine without the air filters. When the filters are on, it runs very poor. I think it is too rich. The filters are new and I have installed a new OEM carb with no changes. What direction should I proceed?
I used to sell Stihl and Partner concrete saws, and we didn't sell very many of them. The thing is, a saw like this makes a small business money, so it is the cost of doing business . Run 'me hard, and put'em up wet.
I really think that crank is useable. The play side to side should not affect the crankshaft. Just bought a new crankshaft for my husky 372 and it has it. Put a new top end on and youve got yuorself a good saw. They make cheaper replacement ones on ebay just as good quality in my opinion.
Donny, how deep would say that scratch in the cylinder was? How deep is too deep to hone? And the scratch i have is just below the intakes that run horizontally through the cylinder, at about the same level as the opening for the bottom boot. is this 'honeable'?
So what is the difference between the $150 piston and cylinder assembly and the $320 one from the local Stihl dealer? Will Stihl offer the aftermarket as the $320 set up, or si there a difference in quality between the Stihl and the aftermarket parts? Do you use aftermarket or stihl?
I never had a small engine without a little sideways play in the bigend. If up and down play is 0 it doesn't bother me. I learned a lot from your video's and started a small engine shop myself! :)
I had a stihl ts400 it was re built but the guy didnt tighten a screw near the flywheel and out came the screw and shredded all the fins on the flywheel. great fun when they all came out the side vent.
In the mean time I am waiting delivery of a MTD 277cc 28 inch snow boower (expected in) around the 21st. I looked at all the stuff on RUclips and you are By Far the greatest thing out there.
those are pretty tough saws I used to use them every day ive seen them ran over by big wheel loaders dropped smashed and submurged in water and they alwayse seem to keep on running
Donnyboy, I rebuilt the top end after the saw was run on gasoline only. Now it seems there's a carburetor issue. what's the best way to rebuild the carb on the ts420? (I know.... loaded question....)
Hi donyboy, if it's on noticed that compression is weakening probably due to worn rings would it be good practice to renew at this point to avert a total failure,thanks
Hey donney I was just wondering if your going to make a vid on the total overhaul of the ts400 engine mostly I would like to see how a professional takes apart the crank. And the bottom end. Thanks a million
is the back half of the concrete cutter the same unit used for the chainsaw version as they look simlar except one has a chainsaw the other a cutting disc or are they different units
I have a TS 400 A real bugger to start new spark plug - gap was set there is a spark from the coil When it does run, seem the Choke changes position suggestions...? P.S. love your video's keep doing them please
Dirt is what killed that saw, lack of filter maintenance. The rings wore in their grooves then started fluttering. Finally a piece broke off and that's what scored the top end. Worked on many Cutquilks and have seen it over and over again. Stihl is the best but they still need maintenance.
Crappy design, had multiple 400 that ran good and strong for a long time with maintenance. Have 2-420 that are crap, cheap parts and crappy craftsmanship.
Don I noticed there is no cam shaft and no intake valve or exhaust valve so, this must be the difference between a two stroke engine and a 4 stroke engine. Am I right Don?
Very interesting and now we have something new on the horizon and that is new electric power motors. I think eventually, the electric motors will get more powerful and give the combustion engine some real competition in the future.
this is a terrible design to work on the ts400 are much easier i cant believe stihl put cylinder nuts under the cylinder
Total shit, will never buy stihl again, have 2 420 that have been nothing but headaches.
Une petite remarque ! Vous devez nettoyer la machine des poussières d abord , et ensuite , vous entamez le démontage au propre Monsieur . Merci ! Bravo ! Algiers..
no it's a good saw just user neglect on this one
@th19940305 i saw some on ebay, i know mowers4u dot com has some
@warbirds3339mike no polar bears where i am, bears are hibernating here. i am 45 minutes from algonquin park

Or cut with water
Agreed, using water is always the best option. However you should still clean air filter frequently.
i just rebuilt mine with all new kit everything and on startup it smoked but i thought maybe for the oil i put on the piston and rings and head not much i let it run for 20-30 min at idle for breakin and it smokes badly on the rev up .......took it back apart to check the rings and head all looks good comp test at 87 -90 no leakdown after 10 min what do you think could be the issue
@1972FordF150 sort of is yes, but after a few it gets easier
the stihl kits are made by MAHLE and the aftermarket ones except for Tecomec don't last as long
@jimbo4840 as i get them in i will redo my vids in HD
i have ts420 and its cranck shaft threaded portion brokedown ( pull cord side ) what can i do because i donot have any option to assemble puull cord as i cannot tight cup with any thing
@warbirds3339mike i would go and see them but i'm from Canada and a bit too far
@fredjohs if he keeps it i charge for my time or he has the option to give it in lieu of payment
@Liamautomechanic that and dirty filters
@warbirds3339mike thanks you, by the way i like the old warbirds
you could especially if you depend on your saw for business and can't be without it or get a backup saw
I just did a TS420 and there's no need to remove the handlebar, you just need a long T27 bit to remove cylinder bolts.
Dony You are a Stand Up Guy, Thanks for all the time You Put into explaining this to us.
Mike warbirds
almost exastly the same thing happened to the ts420 i tore down ;)
@Liamautomechanic that and dirty filters
I just got one in at my store....the saw runs, but loses power when it makes contact with concrete. Thinking it may be the carb?
Hi can you help me,, i have a saw like that and the problem is the blade guard vibrates a lot when acelerate and when lets the trotle go, what can be?
I Have a TS -760 Stihl Runs Strong Still I Don’t Use it Daily But When I Do It Fires Up On the 2nd Pull 😀😊👍🏼
Looks like the piston lost its ring locator pin, causing the ring to turn in its groove and catch the port...! 😢
@duffy630 that's usually from lack of replaqcing the plug
wash it first. then remove the covers and wash a gain. now were clean for surgery. I hate the wrist pin clips.
Very nice and informative video! Thank you!
@countryboy1534 thanks for watching
If you pull the block off you don't need to do that and it is easier to put back together
@pberglin you mean the recoil?
@satan31337 yea for sure LOL
I HAVE THE SAME PROBLEM. I trying to replace the roads and bearing do you think replace the crank shaft is necessary?
thanks.
This is an excellent video. Well done
@warbirds3339mike thank you sir!
@Mrtocoolforyou12 yea exactly
@mrlickzz thanks dude
what should the compression be on this unit?
Hi, I have ts420 that no spark and very hard to pull the cord. The spark plug and ignition are good. What do you think? Thanks
Check switch wires.
@@donyboy73 so everything is looks good when I pull out the spark plug. The pool cord goes fine. It’s easy it’s a it’s good but when I put the spark plug in the pool cord just is not normal.

You are incredible I was charged?90 just for change the spark plug then when I try to use it the belt was broken
there about 600 euros here, for the stihl, con ,saw,

Have a saw with very similar piston wear seen through the exhaust port. Thanks for the test down information.
You can take the whole engine out without removing the handle plus you can do a psi and vac test to

Dony well I guess So Eh....I hunted quite a bit in Ontario Timmens, halibury, Whitney, Cobalt ,are you close to there??
I had a stihl ts400 it was re built but the guy didnt tighten a screw near the flywheel and out came the screw and shredded all the fins on the flywheel. great fun when they all came out the side vent.
not enough oil in the gas,???????????

those are pretty tough saws I used to use them every day ive seen them ran over by big wheel loaders dropped smashed and submurged in water and they alwayse seem to keep on running
Thats typical damage caused by starting the saw then cutting right away without warming it up
Donnyboy, I rebuilt the top end after the saw was run on gasoline only. Now it seems there's a carburetor issue. what's the best way to rebuild the carb on the ts420?
(I know.... loaded question....)
Hey any idea why the gasoline comes out from muffler?
Hi donyboy, if it's on noticed that compression is weakening probably due to worn rings would it be good practice to renew at this point to avert a total failure,thanks
Hey donney
I was just wondering if your going to make a vid on the total overhaul of the ts400 engine mostly I would like to see how a professional takes apart the crank. And the bottom end. Thanks a million
is the back half of the concrete cutter the same unit used for the chainsaw version as they look simlar except one has a chainsaw the other a cutting disc or are they different units
So Dony - do you charge the owner for the teardown/diagnosis or do you just end eating your time and keeping the saw for parts?
Needed to maintain the thing. Too bad, Stihl makes good equipment.
very interesting thanks for sharing
i shoudl send you a plastic welder.. and a pressure washer..... i think you would get alot of use out of both
Hey Dony how would you split the case on this if you need to change the bearing?
hey dany how i can fix the tensor belt on my Ts 420.??
I have a TS 400
A real bugger to start
new spark plug - gap was set
there is a spark from the coil
When it does run, seem the Choke changes position
suggestions...?
P.S. love your video's keep doing them please
check the switch and linkage to the choke
Thanks
Damn it Donny that's a job tearing that down lots of bolts you are the man to do it
whats with the carbon on the top of the spark plug where the boot attaches?
Thank you for doing this. It helped !!!!!!!!!!!!
would you say that this cutter has a weak engine?is Husqvarna a better buy?
thanks. so the stihl one is better and probably worth the money. thanks!
Great video brother! Ive been inside these quickie saws. Its been awhile tho.
If I ran the saw on gasoline no oil what's wrong
this looks like a pain in the S saw to work on.
Dirt is what killed that saw, lack of filter maintenance. The rings wore in their grooves then started fluttering. Finally a piece broke off and that's what scored the top end. Worked on many Cutquilks and have seen it over and over again. Stihl is the best but they still need maintenance.
Crappy design, had multiple 400 that ran good and strong for a long time with maintenance. Have 2-420 that are crap, cheap parts and crappy craftsmanship.
What if your Stihl ts400 is difficult to start, after finally starting it, it cuts off when trying to cut. Thanks
irone93 Having similar issue, how did you resolve it?
cheers
That thing looks like a pain in the ass to work on !
Thank you for this 👍
How do I fix the decompression valve when it has went all the way in
usually comes off with a 13mm socket and get a new one
Helpful information. I need to replace the carb on a TS 420, so good to see this disassembly process. Carb seems hard to get to.
99carnot
It's not hard to take out
You can have it out in ten minutes
Simon Anscombe Thanks! Hardest part was the throttle linkage.
99carnot
When you do them on a daily basis it's done very easily with a pair of wire cutters 👍🏾
Simon Anscombe Thanks. Good information!
were you buy those gloves
thanks for the info
Low octane fuel killed that saw. It went into detonation and the ring land and ring was the weakest link.
LZN197 you are exactly right the saw leaned out and at high speed without much load kaboom
I’ve Had The Spark Control Modules Go Also And Throw The Timing Out Of Whack
I'm the best
Loved watching the tutorial
@donyboy73 Oh lol
Good job brother, keep it like that!
thanks
Don I noticed there is no cam shaft and no intake valve or exhaust valve so, this must be the difference between a two stroke engine and a 4 stroke engine. Am I right Don?
yes big difference
I never saw the inside of a 2 stroke engine until now and I must say, it is a big difference.
OK thanks for the info, I always thought the difference was just oil in a 4 stroke engine and a 2 stroke engine required a gas mixture of oil and gas.
Very interesting and now we have something new on the horizon and that is new electric power motors. I think eventually, the electric motors will get more powerful and give the combustion engine some real competition in the future.
Just...stop talking..andreas stihl invented the electric chainsaw in 1926 and this is something new?? lol
