Good Job...I'm still running my 036 PRO. year 2000. Time for a Fuel Line. Great video. It amazes me that I call STIHL HOTLINE quite frequently. As long as you have your serial number...They can find your correct parts. . Call center in Athens, Greece Thanks for the great video

I expected a challenge when I got into my MS280. I was pleasantly surprised that there are 50% fewer parts to remove, and the job was done in five minutes. Thanks again!

[@jeffnixon4578]

This is an excellent tutorial! Step by step and great camera work! Fixed the fuel leak on my MS290 and my saw is running much better! Thanks for posting!!👍

[@wimcalant8425]

Perfect diy movie. Thx, pushing in the new hose not that easy , made a special plastic tube (from a silicone nozzle) to put over the petrol hose and so pushing it in more equally.

[@mariocestra1156]

Hey, Dony. I followed your instructions to the letter after diagnosing the problem with my chainsaw. It worked perfectly as you illustrated. I ordered the genuine Sthil fuel hose from a local dealer based on the part number. Perfect fit. Thanks very much and keep up the great work you do.

[@jeffstangl1471]

5 years ago and still helping. My MS250 acted up, changed the plug, got everything together and it leaked gas. Not my fault, yay, tracked leak to this line. thank you

[@MrKakuaa]

Best tutorial among many. Too good to be true, but it is real. Best photography and sound recording.

[@cavscout6b]

Thanks-a-million, Don. You made the repair a LOT less complicated and intimidating than it could've been. I figured it would be a nightmare, slice up my hands, and recite a dictionary of malicious swearing. Thanks to your tutorial, I should only need one part, and about an hour.

[@thomastieffenbacherdocsava1549]

I've replaced the carb and fuel lines on a Poulan Pro and I did it with no screw ups. LOL! I've not done anything with my chainsaws do to other priorities. Bought a Sthil clone and it's still a virgin. This breakdown and your insights will help when I peer into the bowls of the beast. LOL! You were the first guy I checked out when I had to trouble shoot my screw ups. Burned up my Poulan pro. Breaking it is how I learned to fix it. Thanks!

[@michaelteti5148]

I was ready to take it to the shop till I saw this. I usually do my own repairs but for some reason this worried me. Thank You. Very clear.

[@stuartbright7812]

Super clear & precise. Just had the same fuel pipe fall to pieces on my MS 290 - thanks alot Don, you saved me a packet !!! From the U.K.

[@duncanmacdonald3164]

Thanks for another great video. I changed the fuel line on my 029 last night and it was fast and easy thanks to having watched this video the day before. Mine was cracked but this video helped immensely. The tip about peeking in between the tank and the saw body to view the fuel line where it enters the tank was helpful. I observed it being dry and then getting wet with fuel as soon as I turned the saw on its side, so I knew what the problem was. Thanks Don.

[@sencoman4998]

Change everything yesterday running great but leaking fuel at the tank. I figured out the problem but not the fix. THIS IS EXACTLY WHAT I NEEDED TO SEE. Ordering part today. Recovering from hurricane IDA down here in Louisiana.

[@miketanner2860]

You made it so easy to replace a fuel line on a chainsaw .I've tried for an hour to make that fuel line on Stihl 044 go through the hole at the neck where it stops , there was no way Donny Sir, unless they sold me the wrong part .but this is OEM. For the 044 at the dealer .

[@micheller8014]

Great video. Maybe do one on the oiler system for the bar? I've seen so many bars burned up because people are unaware of the importance of keeping this clean and flowing. Thanks for taking your time to produce great content and educating others.

[@donyboy73]

Great to hear!

[@BioCosmic--Dust]

Holy cow there is more to that than I would have thought. But I'm glad you mentioned the magic words "Impulse Line". Because when I was 12 years old I had a go-kart, 2-stroke, with a carburetor that I never understood very well because it didn't have a float bowl or a fuel pump. It was the only "impulse line" type carb I've ever had on anything, and I never understood how it could even work at all. So now with the magic words, I can read about these carbs and figure out the stuff I wish I had known then. Better Late Than Never! Thanks!

[@MegaDirtyberty]

Yes, the amount of people who bought stuff into the shop where I worked and said "oh it's just a xxx amount of time to fix right" they never worked on small motors yet they were the experts and not the guys who worked on them all day. Then they complained when the bill came in. One guy bought two saws in and wanted me to make a good one out of two (both were pretty stuffed), I had to use parts from another parts saw we had in stock so he had a decent saw, he complained bitterly that I did that so I took our bits off and just threw whatever he had together. I told him straight that both his saws were stuffed and said I offer no guarantee that saw will work.

[@999thenewman]

@@MegaDirtyberty Then learn to say no to junk - based customers. Make no promises or guarantees.

[@MegaDirtyberty]

@@999thenewman I didn't have a choice, the boss bought it in and said make one out of two. The customer returned a few days later to pick it up and was told what was done to it then the boss came at me because the customer was unhappy. The boss knew what I had to do to it with regard to the extra parts.

[@jeffkreft9872]

Best video on how to change this fuel line. Exactly what I needed for my ms290. Thanks Dony

[@georgemaron5830]

Nice tutorial. Saved me some time thinking it was a carb jet issue. Had a tiny crack in the line at the exit of the tank. Ms310 here.

[@williamwelch7]

Thanks Dony. I looked through my MS 290 owners manual (my 290 is from 2003, and still runs great) and for winter operation I think you may have the pre-filter backwards. The part with the holes (has a sun symbol on the right of it) should be facing up for summer operation, the part with no holes (has a snowflake symbol on the left side of it) should be facing up for winter operation. Also for winter operation, the shutter should be popped up and placed to the left of the spark plug, then back to the right side for summer operation. The shutter should be on the same side as the symbol. Things may have changed, as my saw is 22 years old, but that is what my manual says.

[@markproulx1472]

Super helpful video. The basic procedure would apply to numerous Stihl saws.

[@phillipgonnagarden2786]

Wow. Professional grade tutorial--of the best DIY presentations I've ever seen on Ytube. I hope this will take care of a fuel leak that was subtle, and hopefully the cause of failure to start without priming the carb directly. If so, I'm off to cure my MS 290 with confidence. Thank you for sharing your considerable skills with those of us in the trenches.

[@samwright9913]

Needed to change the carb after sitting unused for many years, great video, thanks, made the job very easy.

[@matej4854]

Great video and explanation. Just one thing caught my attention, when you were talking about that plastic part on top of the air filter that you can flip for winter and for summer. I think that you said it backwards, when you turn that part so the holes are between cylinder and air filter housing that is a winter setup because it allows warm air from cylinder to get to the air filter area. And when you flip it so it's blocked that is a summer setup because you don't want hot air from cylinder to get to the air filter area when it's already warm outside.

[@wanderingandroid]

Yeah, screen on top means its for summer operation. It even has a embosed sun icon stamped on the screen side and snowflake icon on the other side to remind which is which.

[@Schatzjaeger2]

I just stumbled upon this. You are right. It is not to prevent air from coming in at all. It is to allow hot air from the cylinder to be sucked in.

[@tasmedic]

Best tutorial on this subject. Great photography and clear explanation of the method. I live in Tasmania and own the MS 310. This made changing out my carb a breeze. Many thanks.

[@ifraserbc]

great video. simple and concise. but it looks like you put your air prefilter in upside down. in winter the prefilter should have the snowflake pointing up so that the grilled part allows warm air to be drawn in from around the motor so that it can warm the air being drawn into the carb.

[@trcass1]

Great video. I'm troubleshooting my MS 391. i think its a fuel vent problem as it will do a cold start run for a while and wont restart even when i crack the vent. having a heck of a time finding it.

[@jimthompson9824]

Thanks for posting this saved me some money, ? I have 029 Super this did not have the metal flange on the carb should it have one?

[@dalechalkey3729]

my new (few run time hours) farmertec 660 saw leaves a puddle of gas under the unit. originally, i thought the gas tank might be cracked so i removed the gas tank lower unit and inspected it but didn't find a problem. i left the tank off the saw for a few days with a 1/3rd tank of fuel and no puddle was noticed. i reassembled the tank to the saw and let the unit sit on my work bench for a few days and then noticed more gas was puddling. do you have any ideas of what to look at for this issue? i looked at the check valve on the tank and confirmed air was flowing in a single direction. thanks for you expert guidance!

[@puffyd58]

Great video. Very helpful. I wish the rope on my MS290 pulled as easily as yours! When I take the plug out, it pulls fine . . . but with the plug, I feel like I'm wrestling a bear! Very hard to pull. It runs great once I do get it cranked. Suggestions? Thanks!

[@ЮэнДжонс]

I replaced the fuel uptake line on my MS660, however it is still leaking. Would it be possible to add some sealant around the new uptake line? What would be recommended?

[@johnclarke6647]

I put the grommet in with a little 1184 on the seating surface and then pull it into the tank with my hemostats. This keeps the grommet fro leaking and there is usually enough oil left around the hole in the tank to keep the grommet from being permanently attached to the gas tank. Another thing to watch if using an AM fuel line is - did the line go all the way on the carb fitting. If not it can lengthen the line and cause a kink right behind the carb.

[@RitzWood32]

Very well explained and filmed 👍🏻

[@GrampiesWorkshop]

How's she goin'? You mad e look pretty simple. Well done thanks!!!

[@michaelteti5148]

Spoke to soon. You mentioned 290/390. I have a 271/291. Completely different setup. Stihl dealer shows 2 piece fuel line with a connector. Looks like i have to take a lot more apart than you did and not as easy. My first thought was probably correct. I will keep trying. Any suggestions would help.

[@robertoswalt319]

Nice video. I am sure this will come in handy in a year or so when mine will need replacing.

[@johnclarke6647]

I smear a thin coat of 1184 on the hole in the tank to ensure it will not leak after the fuel line is in the tank. It also helps the grommet’s entry into the hole.

[@johncollins8304]

I've found Threebond 1184A, and Threebond TB1184. Which should I get and why please? Thanks.

[@johnclarke6647]

@@johncollins8304 Threebond 1184 is what I use. Let it dry for 15 minutes and then put the parts together. A thin coat is all that is needed. Stihl uses Dirko HT but it does not keep well once opened. I keep my tube of 1284 on my desk in the house, which is air conditioned. Leaving any tube of RTV type sealants in a non air conditioned space will lead to their premature hardening, opened or not. I keep all sealants/glues on my desk in the house.

[@johnclarke6647]

I put a little 1184 on the gromett grove before I put the fuel line in the tank. This insures it won’t leak, again. I pull the line into the tank from the inside of the tank until it pops into the tank. The 1184 helps it to go not the tank.I do the same thing on oil lines that go into the bar oil tank. I degrease the holes with break cleaner an a Q tip before I put the lines in. I also pressure and vacuum test all gas tanks, fuel lines, gas cap and tank vent. They better hold 7# pressure and vacuum.

[@xoxo2008oxox]

Hey Dony, do you think you could do a long term study/review of K100 vs Stabil, Seafoam and baseline ethanol-gas? I just came across my chipper that refuses to start. (had gas in over fall/Winter but fuel shutoff). I dropped the bowl/float and found clear crystals in the fuel. I drained out the tank (hand syphon) and noticed alot of this "debris" on the bottom of tank. I don't know how to clean it out (have to remove the tank or flush it?) but I think I used Stabil or Seafoam fuel dryer/preventer. Preventer at starting, right?

[@simonilett998]

Hi Don, I'm a little confused by something you mentioned in this video on the MS290, could you please clarify it for me. This video differs to what you showed in your summer/winter mode video. In this video you said 'it's winter here in Canada', and installed the air dam with the vent holes facing up, and the hole next to the spark plug was closed off? In this video you said, 'in summer' you would put the vent holes in the air dam facing forward for more air flow'? This seems to contradict your other summer/winter video: For winter mode you showed the vent holes facing forward to allow warm air to flow past the carb, stopping the carb freezing up and allows quicker warm up etc. You also flipped the black flap next to the spark plug boot to open up the air hole for winter mode. In summer, you showed the blank part of the air dam should face forward with vent holes facing up to block warm air flowing around the carb, and the hole next the the spark plug boot has to be closed off to make all of the air flow over the cylinder which promotes best cooling?🤔👍🇦🇺

[@chupacabra1765]

How do I put the fuel filter back on once the new line is in the tank. My 026 stihl line wont reach anywhere near the outside of the fuel cap,

[@donyboy73]

start by putting filter on fuel line then run fuel line from inside the tank to carburetor

[@paulcarovinci6796]

Thank you

[@GlockPunisher1]

It's not enough to set the plate to summer and winter positions, you must also flip the shutter 180° located by the spark plug so it draws hot air during the winter. All it tales is removing the spark plug boot and a screwdriver to take the shutter off and flip it to open a port.

Your vent line may be missing - they don't last forever... Look up Fuel tank vent and there are generally many options on ebay for a start.
