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.
@@AdvancedLawn I told you I would let you know how it turned out. Here it is: 1. Old fuel drained - check 2. 5 minute Sea-foam run - Check (smoked like hell ) 3. Drilled out exhaust baffle using 1/4" drill bit - Check 4. fresh fuel ( Sta-bil premixed 50:1 ) - check 5. new spark plug - check 6. adjusted idle screw as instructed - check BAM !!! the beast is back! this thing runs great! Just like it when it was brand new! Thank you!
Clark Frankenfield phew!😰😜 hell yeah man. I’m relieved now!! Just always keep a few carb tune tools with u on the job and adjust those things like u adjust air pressure in tires for different driving conditions. You’ll catch on fast just like you already have. Good man!
Nate, just a follow up on my trimmer. It's been a year since your advice allowed me to bring my trimmer back to life. I've only had to make adjustments once and it still runs great ! Thanks again!@@AdvancedLawn
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!
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
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.
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.
Oh buddy thanks for those words. Makes me feel like all the time spent editing and holding a camera is helping people. Thank you! I sure will. Got a husky blower to talk about soon. Wait for it
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 👍👍👍
casterman2 woah!! Freakin crazy!!! I can’t believe this. I was just commenting on buckins channel about you man! I was saying how you’re a crazy sun of a gun but we love ya. Thank you!!!! Stick around we’ll have some good times here. I’m going full time in my business so I’ll have more content!
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.
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 ☮️☮️☮️
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.
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
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.
Mine started acting up. Sure enough the screen was clogged. i just took a flathead screwdriver and pried it away from the muffler. It's still there, but there's 1/2 inch opening into the muffler now. Worked like a charm.
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!!!
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
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.
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.
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.
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
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?
@@AdvancedLawn oh ok good! I thought maybe the carburetor settings needed tweaking. Also, it seems that after the first start. They tell you you are supposed to start it in half choke if the engine is warm but I leave it in no choke and start it easier with one pull?
@@ol2533 honestly those extra steps are if it’s having some trouble starting. You should be able to simply prune a few times, full choke and start right up. If it ever starts and dies at full choke, I’d just turn choke off and pull chord. If that dosent work, then I would use half choke! Hope that helps
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?
@@SteveW_71 absolutely! You’re either too lean or too rich. So try turning high key in to the right a quarter turn and test. If that doesn’t work, turn it back and then go another quarter turn out to the left. Fine tune from there. Remember to check things like air filter and the spark arrestor screen in the muffler. May be clogged
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
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 pal. Thanks for watching and commenting. I would reset the jet screws by turning the low and high screws all the way in until they stop. Then open the L screw up one and a quarter turn. Open the H screw open one turn. Back the big idle governor screw out and pull to start. It should idle. Slowly adjust the L scre in and out from there. Have any issues. Come back and ask
@@dad0041 turn the low screw in 1/8 turn in clockwise and try again. Repeat steps until it idles. If it gets worse. Turn counter clockwise until it runs. If that all fails you might need to tighten the idle screw a little or start checking other things like fuel filter located in the gas tank
Instrictions not clear i now have a hole in the center of my piston 😂 jk man great vid just bought a new Stihl weed eater was hoping to find a vid on how to tune you did a great job explaining

Clark Frankenfield yes sir. You’re very welcome! I forgot the sea foam part
@@AdvancedLawn
I told you I would let you know how it turned out.
Here it is:
1. Old fuel drained - check
2. 5 minute Sea-foam run - Check (smoked like hell )
3. Drilled out exhaust baffle using 1/4" drill bit - Check
4. fresh fuel ( Sta-bil premixed 50:1 ) - check
5. new spark plug - check
6. adjusted idle screw as instructed - check
BAM !!! the beast is back!

Great Video, new subscriber. This is from a tech teacher!
Hey Nate!!! You have a new subscriber, Killinger sent me!!
Thanks bro!!! I appreciate you big time. Tell killinger I said thanks
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.
Amazing Information 🧰 Thank you
Helped me out big time thank you !
Awesome! Thank you

It’s it too hard. Still simple. Just a different approach. I honestly never need to use the bulb it’s so good
Could you make a video showing how to tune the Husqvarna 330 LK?

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?
That’s completely normal my friend. Most all chokes will have that effect. Just to help it suck fuel better. Hey thanks for asking
@@AdvancedLawn oh ok good! I thought maybe the carburetor settings needed tweaking.
Also, it seems that after the first start. They tell you you are supposed to start it in half choke if the engine is warm but I leave it in no choke and start it easier with one pull?
@@ol2533 honestly those extra steps are if it’s having some trouble starting. You should be able to simply prune a few times, full choke and start right up.
If it ever starts and dies at full choke, I’d just turn choke off and pull chord.

Hope that helps
@@AdvancedLawn yes agreed. But what do you normally do to start it again after the engine is already warm? I'm able to start it no choke at all
@@ol2533 if the carb is tuned well and everything is good, the engine should start one or two pulls with no prime or choke if it’s warm

@@dad0041 turn the low screw in 1/8 turn in clockwise and try again. Repeat steps until it idles.
If it gets worse. Turn counter clockwise until it runs.
If that all fails you might need to tighten the idle screw a little or start checking other things like fuel filter located in the gas tank
Where do you get the female hex head tool to use to adjust?
Amazon. Get a pack of different ones
What are the factory settings on the la, l, and h.
I believe it’s around 1.25 on the L and H
@@AdvancedLawn thanks, I watched ur other video on drilling small hole in exhaust and it did the trick. I appreciate it
Anyone running a different trimmer head on this model? Wondering if i can put a speed feed head on mine
You can run anything on it as long as it comes with the adapter. The brand name speed feed did not fit. But other brands will
@@AdvancedLawn any recommendations that are similar to echo speed feed?
Wow😂
