Pretty damn good how to for someone that " doesn't do too many how-to videos" Very clear and understandable instruction. Thanks for hooking me up, I'll let you know how it works out.

Good down to earth video now going to try it all out

I searched online for hours and watched multiple videos. This is the only one that fully helps me get my adjustments right. Getting the concept doesn't necessarily make one get the settings right. This kind of thing is hard to learn unless you have someone there teaching you. That's what this was. Thank you!

Nate, thanks for the clear tuning instructions. In order to prevent any damage to the engine by drilling a hole in the muffler, you can remove the rear case, back out the retainer screw for the spark arrestor screen, and remove the screen with a pair of needle nose pliers. The screen can be cleaned with a torch and reinstalled, or it can be left out altogether. The case is easily removed and replaced with a torx bit. Just be sure the pull start is properly engaging before tightening the screws. This was explained to me by an authorized Stihl mecanic.

Great tutorial im new to stihl 2 strokes and this is very informative and helped me a lot

First thing. Thank you! Your instructions are easily understandable. After following your instructions, my trimmer is running better than it did when it was brand new.

Very nicely explained, please make more videos. i am 67 years old with one foot in the grave, i wish there was youtube in my younger years i would have learnt alot from people like you. God bless

Thanks for the video. It fixed my Stihl FS40 issues.

Just found your channel while looking up how to fix my stihl multi tool motors working. I think your channel is going to do really good, keep pumping out the content. Very good charisma and fun to watch. I hope you do some more maintenance videos.

Freaking awesome you can't believe how right on the money you were I have a neighbor's FC 40 string trimmer and she complained that it was vibrating really badly at idle... What was really happening was it was loading up on fuel so bad it never got up on the RPM and the cylinder was loaded with fuel. So I fly a lot of remote control gas airplanes and I thought okay it's either lower high speed needle not even thinking about that crazy muffler and you were right on the money that screen in the muffler was totally plug in about 5 years from when she bought it. I actually loosened a little screw there at that port and the screen came out with needle nose pliers and the freaking thing ran like new. You made me look like a hero LOL. When I gave that thing back to her and said no problem my chest was puffed out so big it must have looked like a peacock! Thanks again. I'm a national service manager for a machine tool builder here in the US and it just goes to show you sometimes you got to look at the simple stuff! I was ready to tear that carburetor off and have my way with it but luckily I washed your video first 👍👍👍

I gotta say Nate you are very helpful and absolutely great at explaining things, I just found your channel and I am so glad that i did because my FS 40c runs like a brand new one after following your instructions on how to and i want to thank you for that, After watching this video i am now a new subscriber to your channel and i can’t wait to watch your other videos because i finally found someone that knows how to explain things about fixing and doing maintenance on Weed Eaters, I’m looking forward to watching future videos of yours so keep up the good work my friend it is well appreciated. Have a great day and wishing Peace And Love too you and your family ☮️☮️☮️

Exhaust screen fixed everything. The more you know.. thanks man!

Leakylou, you had explained very well and helped me a lot on how to tune the Stihl brush cutter. now I do not have to take my Stihl to a Garden tool shop. thank you for your support. looking forward to seeing more of your videos.

This is like the most clear instructions I’ve seen from a lawn care vid thanks! You earned yourself a sub 👍

When Killinger says watch this it’s always worth it! He’s not wrong here either! Thanks great info!

Clear and easy instructions. Nice. Killinger said hello.

Thanks for this video. I was unable to adjust the carburetor as shown in this video. I ended up removing the muffler and removing the screen (I wasn't really keen on drilling the hole) and it was totally blocked. Soaked the screen and brushed it with a toothbrush. I put it back together and was able to adjust perfectly as shown. Thanks again

I have that unit, and by the way check that spark arester on all your stuff.

Thanks Nate just drilled a hole in the muffler issue resolved. You gained another follower

Nate Excellent video my 8 year old Stihl FS 49 C is running like brand new ! It was bogging down and drilling a hole in the muffler did the trick . Also very clear directions on how to set the idle . Thanks again ! Steve

Great video. Thank you for explaining everything so well. 😊😊

That screen on the muffler is called the spark arrestor. You can remove the screw holding it in place, carefully remove the screen. It should be heavily coated with carbon. Stihl advised to use a torch to burn off the carbon. I used a heat gun, some carburetor cleaner and carefully used a small brass brush while holding the screen flat in a hard surface. You have to be careful while using a brush that the screen isn’t damaged. You might not get it 100% clear, but it will then run. My trimmer quit throttling up. It’s a 5 yr old unit. I replaced spark plug, cleaned air filter and ran carb cleaner through the carb. I went ahead and removed the housing( lots of screws) and cleaned the debris from around the motor and inside the housing. A major cause of these small 2 cycle engines is carbon buildup on the spark arrestor which slows down air flow through the motor.

Nate, thanks a million for that advice on the muffler screen. That was exactly my problem, easy fix. Pull it out burn off all the junk with a torch and bingo!!!

Great video! Had my FS40c running great in minutes! You seriously underestimate your self👊🏻

Thank you so much for this video, save me so much time and money.

Tuning my FS40 today... thanks for the help!

Dude. Fixed mine...it was that screen I think. Put a small hole in and adjusted the carb. Running like a champ now. Thanks for the tips!

Thanks brother, saved me some serious grey hairs.

An Awesome how to...clear and concise!!! Gonna try this..Thanks Nate

Good job of explaining, your sound effects of how it should sound are great, don't change a thing 😉 thanks for the advice 👍

Worked perfect for me Nate , thanks so much, runs like new now

Great video, can’t see anyone misunderstanding. Thanks for taking the time.

Thanks for this. I recently got a Husq 330LK, and after about 15 mins of trimming, it won’t idle and won’t restart until it cools. I thought it was overheating or something. Just got an adjustment tool and I’m about to try your guide. I bet it’s a little lean and hopefully that will fix it.

Great video. Thanks for the help. Especially the hole in the muffler trick, she is running much better now!!

Unreal. Better then most large channels.

Just found this channel looking for help on making my weedeater run and greatly enjoyed your content! Great job new scriber

Nicely done! Thank you for the great info. Cheers!

Thanks bud, worked perfectly

I just bought one of these Stihl FS 40c weed eater. When I cracked it up for the first time it will idle but it's real low idle I was wondering if you had any tips for that.

I did exactly what you said and is running like a champ. You Got my subscription and a 👍too. I will be learning from you chanel.👏👏

Amazing Information 🧰 Thank you

Great video thanks a lil tip for everyone mark your screw driver I use a gray marker and put a line on the driver easier to see the turns

Could you make a video showing how to tune the Husqvarna 330 LK?

Awesome! Thank you

Great Video, new subscriber. This is from a tech teacher!

what are those adjustments tools called Nate? and where can I purchase them?

Thank you it helps me alot

Man dang that's a great video

Is there something special about the FS40-C? The primer bulb looks more involved to replace. I watched a video on how to replace the bulb. I'm not sure of the model, but it was just a matter of removing two screws. On the FS40-c, it's not as easy.

Hey Nate!!! You have a new subscriber, Killinger sent me!!

Great! I am Sally. How do I change the strings?

I recently bought a Stihl FS 40C at an estate sale and I can't find anyplace to lube the head and shaft off the trimmer. What am I missing? Thanks in advance! Donna

I take the screen out to clean it, but for the life of me, I always seem to misplace it during reassembly.

I wish you showed how to string it lol I borrowed my inlaws mine won't start, and I can't figure it out!!

Great video bro. Question: my trimmer starts at full throttle/full speed when on full choke and half choke. I need to pull the trigger once and open the throttle and then the trimmer idles. Is this normal? Or do you know what's wrong?

How much should I pay for a FS 40 c stihl strimmer how much should I pay for a fs40 stihl strimmer

What tool is needed to remove the plastic cover on the Stihl FS 40 weedeater?

Good video bro.. appreciate u

Thanks

Can you provide the link for the tool kit at the 3:18 mark? I couldn't find it in the comments? Can you use a screwdriver to adjust it?

I have the same fs40c I won't start with out a little shot of starting fluid and won't go full throttle, bogs down and wants to die. I assume high adjustment for bog issue. Any idea where I might got the tool if I wanted to buy local same day?

I was adjusting the carburetor, however I went to far with it, and now the weed eater won't start. Do you have any suggestions on how to get it to start? It's an FS40c.

hey nate my issue on the same weed eater is when I turn it upside down to edge the side walks it boggs down and sometimes just plain shut off on me..any suggestions on what that might be. have the same model as this one and is about 3 years old

Where do you get the female hex head tool to use to adjust?

What are the factory settings on the la, l, and h.

Thanks!

Wow😂
