Stihl 039 Muffler Modification Complete Applies to 029, 039, MS290, MS310, MS390
Complete Muffler Modification of Stihl 039, same work applies to the 029, 290, 390, Stihl MS290, MS310, MS390, and clones of these models by Hulzfforma, Farmertec, and Hutzl. I call it complete because unlike many modifications that put more or larger holes in the mufflers shell to assist the gases to get out, this modification does that but also removes the material inside the muffler allowing the gases to move within the muffler much better. For example the first cuttings in the video show the performance of the standard/most common type modification. In this modification you see what can be done when you have a complete modification. Once finished with any modifications to the saw that affects flow always retune the saw as necessary, and for those that still want to use the spark arrester screen, these cuts were made with the screen installed.

I bought a G366 kit and thought I lost the key. I went to the Stihl dealer and they said it doesn't have a flywheel key; rather it's cast into the flywheel. Later I found the key in the kit and installed it. Does the MS361 not have a key and the Chinese clones do?
Thank you for your question. MS361; Yes, the flywheel for the ms361 does not have a seperate key, it is moulded on the flywheel. G366; Yes they have a seperate key.
@@bigjersobservations Weird and thank you.
I need to know about the corporate how to put back Gill Put back together Put back together I need to know do they have a Spring format from cooperator to the muffler is there a Spring there
Thank you for your question. No springs are attached to the muffler. The only two things between the cylinder and the muffler are a gasket at the muffler and a cooling plate/heat shield at the cylinder.
Si son bunoas esas máquinas????
They do run well, however they have required some work on them at times as you can see from the videos. Mereka memang berjalan dengan baik, namun ada kalanya memerlukan beberapa perbaikan seperti yang dapat Anda lihat di video.
12mm thin wall deep socket works perfect
Thank you
I have the ns872 a clone of the ms382 and I'm considering eventually doing that too. Luckly my muffler is bolted/screwed together, so opening it up and putting it back together will be much easier. My one issue is I have no way to weld the exhaust pipe onto it. So I may have to hire that done. But I love the increase in power you got. Thank you for showing us the difference without any extra mods. Great video. 😎👍
Thanks for your comment. Glad you found it helpful. Hope you enjoy that saw. All the reviews. I read about It looked pretty good, and it’s a nice size saw for sure.
I removed the main drive pulley and the key came out in two pieces. I am not sure what to do with that or how to get it back in place. I am going to assume I need a new key, but have not found any information on how or where to find one. Any help on where to get parts?
Sorry so late with a reply, and thanks for asking. I have ordered keys from farmertec, and I have also walked into a hardware store carrying my flywheel and found a key that fit. If neither of those work for you, you could try a key from your nearest stihl dealer. The parts list wont show one that fits for the MS361 but they can find one for you if they choose to look. Good luck
Sounds just like a Stihl!
sure does. tanks for your comment
Great vid. So my question is I'm having a problem with not being able to pull the cord. It's stuck and i have the exact make and model push mower. Any ideas where to start looking at first? Thanks..
Thank you for you comment. Answer: Unfortunately I do not have that mower with me. So other than trying youtube videos you may want to try this link: origin.kohlerenginesparts.com/oemparts/l/koh/61857843855d461d145af844/xt675-2075-husqvarna-parts Once you go to that site click on the page 07 starting Use it as a reference. remove the blower housing, about 3 nuts/screws. remove items 1, 9, and 4 as necessary. check for binding and free play as you go check the engine brake cable releasing check the blade under the deck after disconnecting spark wire/cable I am not a mechanic, just a tinker, but i would use this type of approach.
also try the shop manual: resources.kohler.com/power/kohler/enginesUS/pdf/14_690_01_EN.pdf pages: 32 and 33 is a good starting point.
Thanks for posting. I was able to change two of mine today. Thanks for posting. Much appreciated.
Glad it helped
New subscriber here from France...very informative video, out of interest how much louder was it after the exhaust modification ?
Thank you for subscribing and the question. I do not have a meter to measure them proper. My best guess is that there is about a 20 to 40% increase. If I am not wearing hearing protection I don't notice the volume change much but the tone is deeper and I can actually feel a small pressure on my ears after modifying the muffler. I always use hearing protection now.
I'll be!! I have been chasing a start - run - high rev - stall problem forever now on my ms361 (farmertec build) and this was it!! Well at least I am a master at doing Crank Seals now! Thank you!
Wow. Glad to hear this video helped you get her finally fixed. This was a little faster than doing those crank seals I imagine. Like you said, now you've got crank seals down pat, and a great running saw again. Mines 4.5 years old and I work the heck out of it.
Thank you for being so precise on how the belt diagram goes I search all over the TH-cam. You the one who the best tutorials thank you.
Glad you found it usefull an thank you for the comment
Used to be a to the point video on these saws and you could start it in 20 secs.Cant find that simple video anymore.
Thank you. Excellent point. For future viewers that want to get to the point they can scroll to 5:05. Then watch till the 6:00 point where the saw has started. I didn't make it in 20 seconds, but I do accomplish the basic task of starting the saw in 55 seconds, without additional explanations of course. Thank you again
Thank you! A lot of us small budget residential users have gone to gathering our own firewood to cut down on heating cost without wiping out the budget. For many of us this means getting free trees from Blow downs/dead falls or Clean up wood removal from tree fallers. i.e. we need bigger, more powerful saws(on a budget) Enter the Chinese Copies with decent power and somewhat acceptable performance, but not like the oem saws. I've noticed the 373 copies are very popular. They seem to be fairly reliable, easy enough to work on and if not pushed they can handle 24"-28" Bar/Chain combos. Problem is, as soon as you lean on them they tend to stall the chain in the wood. It looks like a Muffler upgrade would be the first and least expensive way to greatly improve performance. Your Modification to the G366 seems to confirm this. Again - Thank You!
Your welcome, and thank you for your excellent explanation of why so many of us opt for these clone saws now days, and we want to get what we can out of them. Especially low budget, low risk improvements that we can do with the tools we have. Thanks again and have a good firewood harvest this year.
Great job on the muffler! That saw has got some power! I have an old Sthil ms361 that I need to do the same thing!🤩🤩
Thanks, glad you enjoyed the mod. Hope you enjoy yours.

Nice... I think I'm going to get the kit and put on the big bore cylinder.... How is the antivibe?
It’s better than 029/039. I saw you have a 291. The AV system is not identical bet very similar to the 391. So I hope that will provide you with a good reference point. Thanks for your comments.
Thanks BigJer, great video
Glad you enjoyed it
Does anyone know what it is a clone of; Husky maybe?
Good question.
Now your going to blow it up. Faster air out faster and more air in. Now you need to re-jet the carb. If you don’t that lean burn will blow it up.
Thank you for your comment. I could of showed readjusting the carb. They normally run lean after the mod if you don't adjust the carb. I spun the H screw out about 3/16 of a turn then finished tuning with a different piece of wood that was not shown. I also could of max reved the saw outside the wood before and between the cuts that are in the video so you could of heard the four stroke. Thanks again for helping to make future videos better.
It’s the low “L” screw you need to adjust, not the H screw. The H screw is only used to set your max RPM. Need to turn that L screw out a 1/4 turn or so to richen up the fuel/air mixture.
@@SG-ig2th Thank you for your comment. I just want to make sure that you understand that both the H and the L screws are used to adjust their respective rpm by changing how lean or rich a setting is. As you change the ratio of lean vs rich you are also adjusting rpm. The simple version is: the L screw is the primary adjustment for lower rpms, and the H screw is the primary adjustment for higher rpms. The objective rpms when using respective screws are reference points in the tuning process. For example: you may have a saw that is max rpm rated for 13,500rpm but due to altitude, bar length, temperature, type of wood, and a host of issues you may need to use the 13,500rpm as a starting point and then finish tuning for optimum cutting effect "in the wood". I recommend that anyone desiring a better understanding of H and L screw adjustments, and 2 stroke theory might want to watch the following youtube video by Craig Kirkman: Episode 43: carburetor adjustment screws on 2-stroke. Many excellent videos are available on the web, and this one does an excellent job with the use of simple yet effective graphics. Thank you again for surfacing an example of another small yet important misunderstanding.
same saw, same mod (mostly) and i did it roughly 10 years ago. saw still runs great. i adjusted the carb but didn't rejet
Thanks for the 10 year update!!!

@@bigjersobservations "thank you for your comment?!"Goood!
Did my muffler like your step one and an improvement. Doesn't seem to run near as hot. I am going to order another muffler and do like you did and do step two.. I check my jetting pretty regular with just a fine tune of a screw.I am not worried about warranty as it is out of warranty.I have the stock unmodified muffler but probably never put it back on.
I'm glad to hear that it is working out for you with the usual positive results. Good luck with your next step, and thank you for your comments.

Great video. Thanks for sharing.
Thanks for watching!
Thank you for this video. I bought two of these over a year ago and neither one would start. Sold one and the other has been sitting. I've replaced everything I could think of (Carb, spark plug, starter coil, fuel filter, etc.) but I didn't know about this. I will have to give this a try and I hope it fixes it. The Farmertech community got mad at me when I complained about it online and they said I shouldn't buy these clones unless I know how to fix them. Farmertech wouldn't honor their warranty either (the saws were DOA) and said I should know how to fix them also. Overall, a very disappointing experience with them.
I hope it might help out. If you have no spark and because you have already tried spark plug, and coil, this just might be the issue.
These take factory Stihl vents?
Thank you for your comment. It should fit. I have never used Stihl OEM tank vent "# 0000 350 5800 Fuel Tank Vent OEM". However, They look identical and farmertec says that they are a direct oftermarket replacement, and they cite this Stihl part number.
I have this issue. Just bought a 5800 part. Have not installed it yet. Thanks for the video.

Thank you. Glad you found it helpful
i have a 366, that the flywheel nut wasnt torqued properly which allowed the flywheel to move slightly when cranked one time. (i think) the engine backfired i immediately opened it up to find the flywheel loose and found the key inverted causing the key to shift and chip the key slot. ive considered using jb weld to repair the chip, but i reinstalled the key and flywheel as the chip damage was about 20% of the bearing surface. and cranked her up starts and runs okay i would suggest all 366 owners remove the flywheel and verify key orientation and correctly torque the flywheel nut.
Thank you for your comments Scott. You are absolutely right. Your comments caused me to look back at the running backwards video I made. When we diagnosed the problem it was a split key and as we took the flywheel off it was very obvious that the flywheel was loose. Nine months ago i received a comment from a viewer that had a bad running G366 and he had put 2 carbs on the saw., After watching the video he checked his saw and found a loose flywheel and split key. He replace the key retorqued the flywheel and now it runs fine. On other videos we have received comments about lousy runing G366s. I agree, everyone that owns a G366 might seriously consider taking the flywheel off, inspecting the key and slots and retightening the flywheel.
That's a bad habit to get into when you put on your chain brake, it should not even be bothered with,
Thank you for your comment

WHAT ABOUT THE MAIN ONE YOU DID NOT TOUCH I HAVE THAT ONE THAT IS BAD.
Thank you for your comment. Please disreguard my first response to your comment. The "MAIN ONE" you comment on I believe you are talking about the drive pully with the little star embossed on the bottom of it. Once you removed the blade you should be able to pull it down and comes right off depending on rust. Penetrating oil overnight should take care of that. If that star is sheared off then the drive will still work but the blade will stall in medium to heavy grass. Recommend replacing pully with new part. However I have welded a new star and then ground it to fit with dremel. Best of luck
"now let's go around top and get those other two screws." I found one of these at a curb, took two oil changes in a day to clear that up, now has a clean carb, works great. But those "two screws", that was driving me nuts, I couldn't figure out why that would come off. Thanks for posting this.
