After a very discouraging encounter with the local Stihl dealer, who wanted $70 just to tell me what might be wrong with my saw, with repair estimate possibilities nearing half the price of a new saw. I took my saw home and started taking it apart myself. I found this cracked impulse hose on my 1996 024 Super, a fine little German chainsaw. The impulse hose and the carb kit were $35 and my little screamer runs like a champ. Thanks Dony.
Every time I watch one of your videos I learn more about the features of my older Stihl chainsaws. Using the impulse line tip and intake boot tip I fixed my 028 WB so that it now runs better than ever. Thanks again for all the attention you pay to these great saws.
No problem. I know you put a lot of time and effort into producing videos. They may not always pique my interest in every case, but they are always appreciated.
This is very true regarding the impulse line. I have an fs90r and an fs130r. The fs90r purrs like a kitten and runs stronger than the fs130r, which obviously is supposed to have more power than the 90. I installed a new carb and fuel line kit on the 130, tried to adjust it and it runs ok but erratic. Turns out the impulse line was cracked and not providing the vacuum for the carb diaphragms to work like they're supposed to. Replaced that impulse line and now the 130r runs like the 90r. Awesome vid!
excellent video! I want to change the impulse line on my Stihl 026. Which parts should I take off so that I can gain access to the line? I would also like to check the carb boot while I am at it. Thanks for the videos, they give me the courage to do my own repairs.
It runs on the vacuum pressure from under the piston to actuate the pump diaphragm on the carburetor. Piston goes up, pressure in the line gets sucked into the crankcase. Piston comes down, pressure builds in the impulse line.
Nominated! You have a great channel and are very organized and make it easy for us to search for our problems with our power equipment. Keep up the good work!
I have a craftsman 16” 36cc ---06118D20933. It starts up ok but bogs down when I start to cut. If I hold it tip pointed up & cut that way it runs fine. After cutting for a few minutes I can cut holding it level. But it will start to bog down again. It is not leaking any gas. Does this unit have an impulse line? Thank you
Loss of impulse pulse in a two cycle can be a intriguing problem. I have a used Stihl HS 45 that I picked up last week that has a similar problem. Normally I would just replace the impulse hose in normal routine maintenance if the saw indicated it was loosing fuel flow but the HS 45 has a stand-off isolation block used as a channel for the impulse pulse. My carb and fuel lines are pluperfect, so it is not them. I have two Zama C1Q carbs and I have swapped them out with the same results. It has to be the isolation block. I will check it out, today. Your thoughts? The hedge trimmer will run but only for a second or two, based upon how much I primed it.
Hi there Dony, great videos! I came across your channel after getting a good deal on 3 saws, an 011AV, 024AV and an 036. I have gone in and done lots of needed cleaning and inspection on each unit. The 024 had a running issue I tracked down to a bad impulse hose just as you have here (fast idle that could not be turned down and intermittent idling, falling flat on revs). The pressure/vacuum testing vid was helpful on that! The 011 is good to go. Question on the 036 though: The clutch was run hot and cooked the bearing and it ate crankshaft. I assume that needs to all be replaced. I see after market kits out there. I worry about quality. Are there brands to consider safe or do you know of any to stay away from. I paid up buying Sthil branded hoses for the 024 repair. Was that necessary? Are there good sources you can recommend to buy decent quality parts (OEM or aftermarket) from so I can thoroughly restore the 036? Crank kit, gaskets, hoses ect... Thanks!! Jim
Is there a vidio to show how to get off the impulse hose (the end that goes into the cylinder). I can see it in there but no clue as to how to get back in there to disconnect. It appears even too tight for needle nose pliers and I have disassembled much of the saw but can't seem to seperate the trigger/handle from the cylinder to get back in there.
Hello from Europe! I bought a second hand Sachs Dolmar 111 3 months ago. The day I bought it It took a bit to start it but started and looked good. After that day it was imposible to start it again. I put new gas, changed the spark plug, clean and rebuilt the carburetor, and clean exhaust. After that the chainsaw would do a start but within 3 seconds it would stop again. I gave up. This week I had some time and decided to try again and surprise, it starts perfectly!! I tried a couple of days and no problem at all. The question is; Do you think it may have something to do with the temperature or humidity?
Wow thanks for that quick tip,that was exactly my problem on my Makita DCS340. Merci beaucoup Don,j'apprecie enormement ton travail et le partage que tu fais. Sharing is caring .Thanks budy. Best regards.
I have a stihl 025 which stopped running after the winter. Put fresh fuel in and won’t start. Cleaned out carb & still won’t start. Can get it to run for a few seconds with starting fluid. The original vent tube is full of fuel? Would that prevent starting? Also do you have a video showing how you disassembled that chainsaw to access the impulse line?
Donny Boy, my Stihl 025AV had symptoms of a leaking impulse line,, hard to get the carb adjusted and it dies if the saw is inverted, I replaced it impulse line and have not yet tested it as I don't want to anger my neighbors on Thanksgiving. I have examined the old line and intake boot. Nothing obvious in the way tears. I I replaced both. I did pressure and vaccum test the impulse line and it does not hold pressure or vacuum after 7 minutes. I think there is a very small leak not like what you showed in the video. Is a small leak enough to cause issues?
Thanks Dony. Was hoping to see you take it down, so we could see how far we have to tear the saw down to get to it. looks like both top covers, air filter, handle, carburetor, and we can get too it.
impulse line is the same id as a fuel line , can i just bypass this mess and use a standard fuel line? and will a carb boot for a 034 / 036 fit a 031? only ones i can find fora 031 are expensive and 034 aftermarket ones dont look much different.
love the knowledge Donyboy73 thanku for the heads up its a really important part to look after the Outdoor power equipment old or brand new to avoid problems down the road when using them in the middle of a task for example cutting the logs of wood safely and cutting the grass clearing leaves with the leaf blower and trimming hedges with the Hedge trimmer and clearing snow with the snow blower or what ever as the common problem but a different model or unit that :)
Hi! Am writing regarding my father's mower. A TroyBilt w/ a Kohler 19hp engine. It will NOT start. Tried starter fluid, did not work, gas filter ok. Engine turns. I am thinking it would be either the key or the connection to the carb. Any Suggestions will be appreciated. Keep up the good work, love watching your channel. There is something new to learn. Gilberto
My vote is in. REALLY enjoy your videos. Do you have one on the Lawn Boy/Toro "personal pace" system and how it works? I have one I will be tearing into in the spring. It seems like the drive fails to dis-engage even when engine is not running? I have not torn into one yet as mine is brand new, but I bought a used one as a project. Too good of deal to pass up.
When I rebuilt my Stihl 029 for the third time I put a new impulse line on it. Later I had to replace the coil because it was bad. It ran great for a week or so, even after I replaced the coil but all of a sudden it would not idle. It cranked and ran great at high speed but at idle - it died. I could think of all kinds of possibilities, seals, carb and other things that could cause it not to idle but I felt it had to be something simple. . I started wondering if it was the impulse line? Did it get partially unplugged when I put the new coil on it? Yes, it had about 3/16 of an inch, so I push it back on the fitting and put the saw back together. It ran and idled like a champ, so that was the problem. I decided if it gives me anymore problem I will remove it , clean it with break cleaner and put it back on with 1184. If able I will also put a small cable tie on it to make sure it stays on the fitting.
Great Video Dony. I have the same exact chainsaw and had the carb kit replaced. It ran fine for a little while but now when I start it it seems to idle fine and then when I give it some throttle it dies out. Could this be the problem? I can send you a video later if it will help. It was my grandfathers chainsaw from the 1980's and i'd really like to get it running perfect again.
Hi Dony, I have a STIHL Super 039, I have this same problem you talked about. I have rebuilt the carburetor and the saw will not run properly or I cant tune the carby. I can get it to run, but the saw idles rough and bogs down when I give it some gas. I have also clean the arrestor filter in the muffler. I have another saw 029, and this runs great. I placed this carby on the 039, and it still wont run properly. Can you offer any other suggestions to try and get the saw running. Thanks
Good info but - I watched your videos on the STIHL 017 clutch & oil pump area and ordered a double handful of aftermarket parts and spares. Still no chain oil. Yesterday I ordered an oil pump. Today I wish I had considered an impulse hose and intake boot even though they aren’t connected to the chain oil system. How about a list of likely soft parts and parts that are likely to need replacing? For those of us willing to try aftermarket parts, the cost for extra parts is not much compared to multiple part orders.
Hey I got a quick question I got a McCullough. Mac 4600 chainsaw and I've noticed I've had to switch all the fuel lines especially the pulse line but the one problem I'm having is how can I get down in there behind the case and the motor to plug the pulse line in there's no way you can get down in there you got a video on how to change that on that saw
I am working on same saw. Was running but idle too high even with screw adjusted all the way out. I then noticed a broken in half impulse line. I replaced it and now saw won't start. Not getting fuel. Spark plug is dry. Any ideas?
Hey, is it possible to change the impulse line on stihl 023 without disassembling the whole saw? I just tried to take off the orange parts and was wondering how the intake boot comes off the orange plastic parts...
i have old stihl 011 AV chainsaw, i do not know where impulse line goses, one end of impulse line goes to fuel tank and other end goes to where? or should be simply sealed with a screw?
I have an Echo CS-600P. I cleaned the carb due to hard starting even when new. Now, the saw starts well. However, it dies slowly in 5 seconds when idling. Low idle is at 1.25 turn out. I checked the intake boot, fuel line, and impulse line. All like new. Any recommendations?
At my request for help you answered if the spark had "spark" yes it does. I put a new one, cleaned the carburetor and it did not work. Made sure it had compression, also confirmed the relay under the bowl works. The motor is a Kohler, s/n 3603332093, spec sv590-0017 Courage. Please advise, and thanks for your help
Hai Dony thanks to Your vid I just repaired my 024 , the impuls line had come of on the engine side,I have thinkert a lot on other brand,s whom all had the carb direct on the cilinder with no impuls line like this Thanks Man!
Do you remember what your symptoms were? I just picked up an 024 and its starts up fine, but as soon as you try and make a cut with it, it just runs out of power and dies...
hat is the impulse line for,ive been working on my saw,so for i cant seem to get it going,i poppw off the flywheel and roke a fini ordered a new one and it hasnt got a key,looks like ill have to buy another.thanks
Great video. On an 028 AV Super, with the filter cover removed, what is the tube called that is on the left side just above the master switch. I can't seem to find it on any parts diagram. Mine fell apart (disintegrated). It had small set screws inside both ends blocking the line.
would you have a Picture from the all Tee fuel lines setup going to fuel bulb and etc. my saw is a STIHL MS250 year 2005, with could/EASY start (bulb fuel) I toke it indo a "dealer" and he disassembly and was not able to put together. I Just need a Picture from behind the carburator to ser these hoses and "T" hose connection. thank you
Don: I want to know how to remove the screen from the fan on that Kohler I wrote you about. I was not able to figure it out and was not able to check for the key on the shaft. Please advise. My father wants to buy a new mower and am telling him not do. BTW he is 93 this month. I already sent you the information on the Kohler. Thanks Don and keep up with your videos, they are very informative. Gilberto
Random question: is there a good way to get light rust off the inside of a gas tank? I got an early 70s 3hp brigs im trying to bring back to life. I was thinking about using CLR and drying thoroughly
He dony, I have an o34 that wont start. I replaced the carb and that didn't work. Checked for spark have reasonable spark, however i counld not get it to fire on starting fluid. Tore down the saw and performed a vacuum and pressure test and it held10 psi. No leaks at impulse line or intake boot. Could the plug be malfuntioning when installed?
Hi dony i live over seas i have a Chinese chainsaw carb it have 3 lines i dont know the third one go's to the motor can i send you a photo of the carburetor thank you
Does the Poulan chainsaws have the impulse hose on it? I have a new Poulan Pro which will crank, but won't run no more than about 15 seconds before it dies. Like a dummy, I burned the box it came in before making sure the saw runs properly.
I would’ve really appreciated a quick run down on how much to strip the saw in order to remove and replace the impulse hose! Never mind, many thanks for the advice regardless. (I can more or less see the strip down at the end of the video.
Dony, I 2 have an 024 saw. Hard starting son of ah gun. Always has been. Had it serviced 1 time and wz no different (they said they installed a carb kit, cost $62.00 American). Starting either gets it going everytime. Good saw, I have had it over 20 years. Just a bear 2 start, unless U have starting either. Bowzer.
I just rebuilt the top end and installed new crank seals.. Upon assembly, I forgot to reconnect this line.. (Stihl 021) Upon trying to start it up for the first time it acted fuel starved.. I'll reconnect, and hopefully problem resolved and many many years of uninterrupted service !!
Hi Donny great vid I got a stihl 361 That ceeps running hot Even after replacing every part on te oil pump every seal is new even the hose is new And after running for 5 min the blade whil get real hot Even to its geting oil 5 sthil dealers dont have a clue wat coud be rong
Not like u woud expect whit every part replaced Oil poors out of the bottem of the saw a bit like it aint getting truw the hole of the blade but I tripel checkt and that al clean I workt on these saws fore 10 years and never hade this problem before Sorry fore the bad englisch typing i do my best
if your channel rocks it will speak for it's self .... your content does not require you to ask for comments , votes ,, subs .,.ect... your doing fine without resorting to that

Nice job on video.Nominated you today.I have been a Marine,Small Engine Mechanic for 30 years and you make nice videos.You help a lot of people out.
Great tip! Really not much of a decision once it’s torn down to replace questionable boots and lines! Your videos are always spot on!!
Wray from Ohio

what is an impulse hose? great video, thanks for your time.
Oh, Dony. Sorry for a goofy question. What does the impulse hose do?
It runs on the vacuum pressure from under the piston to actuate the pump diaphragm on the carburetor. Piston goes up, pressure in the line gets sucked into the crankcase. Piston comes down, pressure builds in the impulse line.

Hi DonyBoy73,
Just nominated you. Yours have to be some of the very best instructional videos available anywhere. Keep up the good work!!
I live in a village near Ledinci. I must admit that I learned a lot with your videos.
I have a craftsman 16” 36cc ---06118D20933. It starts up ok but bogs down when I start to cut. If I hold it tip pointed up & cut that way it runs fine. After cutting for a few minutes I can cut holding it level. But it will start to bog down again. It is not leaking any gas. Does this unit have an impulse line?

Would it be possible to make a jig to attach to the front of carb to presure test the whole system if you do a lot of these. Nominated you for sure.
Cheers Dony I got my echo blower working this week thanks to your videos. Many Thanks
Your videos are tops! I nominated you for youtube's "On the Rise" channels.
thanks!
Timothy Barney how do you nominate someone or agree with your vote please?
F Dort youtube is no longer taking nominations.
Hi there Dony, great videos! I came across your channel after getting a good deal on 3 saws, an 011AV, 024AV and an 036. I have gone in and done lots of needed cleaning and inspection on each unit. The 024 had a running issue I tracked down to a bad impulse hose just as you have here (fast idle that could not be turned down and intermittent idling, falling flat on revs). The pressure/vacuum testing vid was helpful on that! The 011 is good to go. Question on the 036 though: The clutch was run hot and cooked the bearing and it ate crankshaft. I assume that needs to all be replaced. I see after market kits out there. I worry about quality. Are there brands to consider safe or do you know of any to stay away from. I paid up buying Sthil branded hoses for the 024 repair. Was that necessary? Are there good sources you can recommend to buy decent quality parts (OEM or aftermarket) from so I can thoroughly restore the 036? Crank kit, gaskets, hoses ect... Thanks!! Jim
Dony, just wondering if you could replace that impulse tube with a regular fuel line ? Which might be a little more flexible. Thx for the great info.
answered several questions Donny.....thanks ;)
Is there a vidio to show how to get off the impulse hose (the end that goes into the cylinder). I can see it in there but no clue as to how to get back in there to disconnect. It appears even too tight for needle nose pliers and I have disassembled much of the saw but can't seem to seperate the trigger/handle from the cylinder to get back in there.
Same problem here ! on a 024stihl How do i thake the damm thing apart and visa versa
Hay donyboy nice video, but can you explain purpose of impulse line and how its work?? Can not find any vid. on youtube about that. THX
The purpose of the line is to transfer the vacuum created by the piston to the carburetor in order to suck fuel to the carburetor.
Thank you Jose, that's good to know.
Thanks for the information! I have been doing more and more 2 stroke repairs and this all helps me know what to look for.
Anyone who has saved even a few dollars following Don's advice should take the time to nominate him! I gladly did!

Thank you. I looked up Jeremy Fountain. Good information, but I much prefer your channel! Please keep up the good work. Also nominated you.
I am working on same saw. Was running but idle too high even with screw adjusted all the way out. I then noticed a broken in half impulse line. I replaced it and now saw won't start. Not getting fuel. Spark plug is dry. Any ideas?
Hey, is it possible to change the impulse line on stihl 023 without disassembling the whole saw? I just tried to take off the orange parts and was wondering how the intake boot comes off the orange plastic parts...
i have old stihl 011 AV chainsaw, i do not know where impulse line goses, one end of impulse line goes to fuel tank and other end goes to where? or should be simply sealed with a screw?
I have an Echo CS-600P. I cleaned the carb due to hard starting even when new. Now, the saw starts well. However, it dies slowly in 5 seconds when idling. Low idle is at 1.25 turn out. I checked the intake boot, fuel line, and impulse line. All like new. Any recommendations?
Just sent nomination. Keep up good work. You're the best dony.
thanks i fixed my chainsaw with your advice, I am not cheap but, I hate to take my tools formaintenance and many times they "fix" them wrong.
At my request for help you answered if the spark had "spark" yes it does. I put a new one, cleaned the carburetor and it did not work. Made sure it had compression, also confirmed the relay under the bowl works.
The motor is a Kohler, s/n 3603332093, spec sv590-0017 Courage.
Please advise, and thanks for your help
Whats an impulse hose ive never knew what those are / what they do??
yes make small metal plates and a liner of rubber for the intake and exhaust
Hai Dony thanks to Your vid I just repaired my 024 , the impuls line had come of on the engine side,I have thinkert a lot on other brand,s whom all had the carb direct on the cilinder with no impuls line like this Thanks Man!
Do you remember what your symptoms were?
I just picked up an 024 and its starts up fine, but as soon as you try and make a cut with it, it just runs out of power and dies...
you should replace coils, points and condensers, gap points at .020 and use oem parts
Thanks Donny I will send the video as soon as possible
wow! simple video, simple problem. thank you for sharing your knowledge with us. very helpful brother
Do you think it is good practice to change all fuel lines when you do carb kits?
great video but next time show how you took it apart and put it back again . Thanks you
How come you make such awesome videos dude
hat is the impulse line for,ive been working on my saw,so for i cant seem to get it going,i poppw off the flywheel and roke a fini ordered a new one and it hasnt got a key,looks like ill have to buy another.thanks
Great video. On an 028 AV Super, with the filter cover removed, what is the tube called that is on the left side just above the master switch. I can't seem to find it on any parts diagram. Mine fell apart (disintegrated). It had small set screws inside both ends blocking the line.
That sounds like the fuel tank vent tube.
Where do you buy your carberators for stihl. Bought a cheap one off amazon and was not pleased
would you have a Picture from the all Tee fuel lines setup going to fuel bulb and etc.
my saw is a STIHL MS250 year 2005, with could/EASY start (bulb fuel)
I toke it indo a "dealer" and he disassembly and was not able to put together.
I Just need a Picture from behind the carburator to ser these hoses and "T" hose connection.
thank you
Don:
I want to know how to remove the screen from the fan on that Kohler I wrote you about. I was not able to figure it out and was not able to check for the key on the shaft. Please advise. My father wants to buy a new mower and am telling him not do. BTW he is 93 this month. I already sent you the information on the Kohler.
Thanks Don and keep up with your videos, they are very informative.

I'll vote for you any day! But it's hard to vote for you as being on the rise when you're already tops!
This vid is perfectly clear - same app and OS.
What is harder to work on. Stihl or husqvarna.....echo???
Great video, stihls are definitely the best!
very good tips dony! keep making these fantastic videos man!
Random question: is there a good way to get light rust off the inside of a gas tank? I got an early 70s 3hp brigs im trying to bring back to life. I was thinking about using CLR and drying thoroughly
He dony, I have an o34 that wont start. I replaced the carb and that didn't work. Checked for spark have reasonable spark, however i counld not get it to fire on starting fluid. Tore down the saw and performed a vacuum and pressure test and it held10 psi. No leaks at impulse line or intake boot. Could the plug be malfuntioning when installed?
Hi dony i live over seas i have a Chinese chainsaw carb it have 3 lines i dont know the third one go's to the motor can i send you a photo of the carburetor thank you
send me the link but yes this could be your problem
How do you check for an air leak through the crank shaft bearings? Some sort of leak down test?
Okay Dony, you've been nominated for On the Rise. I didn't realize I'd have to fill out a form :-) Hope it works for you.
i have seen many cracked impulse lines on those, worn out crank bearings and seals too
Have you ever delt with any shindaiwa chain saws?
fantastic videos, pl show taking off main handle housing bolts
Does the Poulan chainsaws have the impulse hose on it? I have a new Poulan Pro which will crank, but won't run no more than about 15 seconds before it dies. Like a dummy, I burned the box it came in before making sure the saw runs properly.
usually not, often just turning out the L and H screws helps
Thank you, Dony.
I'm trying to find the part number for an impulse line on a 028wb Stihl chain saw, model year 1979.
Just sent a nomination. Thanks for the videos
Love the info buddy, respect your knowledge
I would’ve really appreciated a quick run down on how much to strip the saw in order to remove and replace the impulse hose! Never mind, many thanks for the advice regardless. (I can more or less see the strip down at the end of the video.
i think i used up my 500 characters nominating you. good luck you deserve it.
it sends impulses of air to the carb to make itable to pump fuel
I nominated you-- said a few kind words... like, I dunno... YOU'RE AWESOME...!
just a handful, they are good saws
Dony, I 2 have an 024 saw. Hard starting son of ah gun. Always has been. Had it serviced 1 time and wz no different (they said they installed a carb kit, cost $62.00 American). Starting either gets it going everytime. Good saw, I have had it over 20 years. Just a bear 2 start, unless U have starting either. Bowzer.
I just rebuilt the top end and installed new crank seals.. Upon assembly, I forgot to reconnect this line.. (Stihl 021) Upon trying to start it up for the first time it acted fuel starved.. I'll reconnect, and hopefully problem resolved and many many years of uninterrupted service !!
+Vdubin64 it's definitely a critical component!
not yet, thanks

if your channel rocks it will speak for it's self .... your content does not require you to ask for comments , votes ,, subs .,.ect... your doing fine without resorting to that
Voted and praised you and your channel
it sends impulses of air to the carb so it can pump fuel properly
