My 12 year old Granddaughter now calls herself Chickanic . She has been interested in any thing with a motor . I've asked Her to " test " the lawn mower so I don't have to cut the lawn any more . Thanks ....
Lol lots of little chickanicks walking about
That is pure awesomeness! Thanks for watching!
Genius!
So, for 50, 60, 70+ years you could change the plug wire to your 2 stroke mopeds and other gear but now you can no longer do it but you need to change the entire coil? Yeah, this is not progress, economic nor ecological. Shame on you Stihl and I suspect other makers too. 🤬 Good video though.
Thanks for the video, I usually put dielectric on plugs and such makes them come off easier, thanks again, you make it look easy
Yes. However in my experience, to much dielectric grease can have averse effects in cold temperatures. Not plug boots but like trailer, spreader and plow pigtails. I would assume the heat generated by the cylinder head would be enough to mitigate this issue there.

Dielectric grease? What part number brand?
Makes all the difference. Just a dab will keep the boot popping right off even years later with no problems.
Hey Chickanic, thanks for the good video. One thing that can make it easier is to thread your coil wire, without the spring terminal yet attached, through the boot (put some grease on the wire), then attach the spring terminal, then pull it back through (reverse it), being careful to seat the spring properly
You're spot on. That makes the whole thing a lot easier!
Big brain move!
Good morning from the 🇬🇧.. just woken up so will watch with my first cup or coffee.. hope you and the family are all well
I've gotten my fair share of bloodied knuckles pulling off plug boots. I wish those Stihls used the screw on type coils and boot ends. That job would be easier for sure.
I can't say for sure on the newer Ms saws but the old 029 etc type saws you could screw a new wire onto the old coil if it got chowdered up.
They make a tool named a "Spark Plug Boot Puller? They hook around the boot near the base of the boot and pulls the boot right off. A labor and damage saver!

yea,,,,,it's called a pair of pliars,
Sometimes just being smarter than what you're working on will get things going.
I know this was 4 months ago, but those pliers do not fix into small engine tight places. They do not work on most new cars eather.
Cool video and very good advice!
Only one thing: I find it easyer first pusging the wire through the boot, then fit the connector on the wire and finally pull the wire with the connector attached back through the boot until the connector fits. I also find it easyer to push the hole into the wire with a thin nail or an (german:Ahle) and then fit that hook from the connector. Before doing so i pierced my fingers several times... Not to bad but also no fun... 😁
I agree much easier put the wire through the boot first, then affix spring-connector, then PUT A PIECE OF JUST THE RIGHT SIZE SHRINK WRAP (that you have sleeved onto the plug wire beforehand) around the "straight part" of the spring-connector, then a little silicone grease, then back into the boot gently helping from the front. (If you are desperate and do not have shrink wrap, at least use a couple of turns of Scotch 88 -- leading out the back of the boot)
It was running when I shut it off last time I used it
Ain't that always the story. LOL
I been watching your vids, and I have told you, You're Awesome. You do Excellent Close up, descriptive, and Even part Numbers, with High quality resolution. You give such detail, that makes me feel confident I can fix it. I Thought I was Already a sub. Here I Literally had to sub today. 😃
I was close. I had to repair a pulled ignition wire on a Stihl BR600 a few weeks back. I didn't cut the wire, but I did cut the boot to make it easier to install the wire/coil back in. Will definitely use grease and stretch the boot next time.
So it wasn't just me thinking the wire coil has become tighter, thanks! I've had them come several times a week too.
And about the grease - I don't use grease for that, but a tiny squirt of WD40, it'll evaporate and let the coil sit tighter in the boot. You can try it some day, when you are out of grease.
When it doesn't start and it's suspect that it is flooded then pulling the plug to dry it out can speed things up as well as verify a flooding issue. I use spray silicone on plug wire boots.
I've used and serviced many Stihl saws over the years. If you don't release the choke lever after it fires just once ,it will flood. They are great saws , but tempermental starting !
If you have not already shown it, showing the correct way to remove the boot would help stop ths damage. This was a very good tutoria, I anjoy watching you work
Yep good one. Always just dump customer fuel and use mine.
The individual that owns that chain saw might need to watch your videos before trying it again.
Thank you for a great video, from an old retired trucker trying to supplement income by repairing small engines in my home shop. You are a great teacher and I look forward to all of your videos. Thanks again from East Texas.
Hi Mike. I’m retired diesel mechanic who is also fixing small engines and old tractors
Hope you stay busy
How did you learn all about small engines
Awesome 👍! I can use this info for sure! Thanks so much! I use Stihl and Husqvarna equipment and love to do as much as I can on my own. A few months back I had to change out the original spur sprocket on my 2012 455 rancher my dad purchased as bday present back in 2012 to help him on his property in the country. Thankfully my plug cable was not obnoxiously tight and popped off easily. I have also learned the trick of grabbing them in such a manner as to grab the wire inside the boot so as not to pull it all apart. I took some auto tech courses years ago and learned they will rip apart too if pulled incorrectly. A little finesse goes a long way in saving time and money.
As to the gas issue my father taught me to always mix my own to avoid any issues and always mix per each tools specs. We also use non ethanol high octane. As you mention not all pre mixes are equal or designed for everything. You can easily burn up a small engine if the mix is not right. I learned this lesson the hard way when doing yardwork for my aunt using her weed trimmer and the gas someone had mixed incorrectly for her and was low on the oil side of things. I hard seized that engine in short order. So yup wrong mix gas can really mess you up quickly.
Today is the first time I watched your channel. I watched the "DO NOT BUY this poorly built chainsaw!" video. Then I watched this on since I have a Stihl MS180C that I will do the repair work on and I want to pick up tips on repairs. I totally enjoyed the way you diagnose and perform your repairs and the way you present it. Looking forward to watching more videos
I've found dielectric grease makes removing plugs and connectors a lot easier as well as it's other benefits (waterproofing, dirt/dust blocker etc) and despite not being conductive it does't interfere with the wire connections.
Or spray silicone works to on plug boots
You wouldn't happen to have a video to post on about a ignition coil for a Stihl 029 model the original please no offense to your man but you are an attractive woman and even sexier because you know how to work on stuff hated to hear you saying you was closing your shop hopefully you're still there to help us viewers that need a question answered😊 😊
I've spliced plug wires. Just cut them in a spot where it can't shock and use a thin copper wire (large gauge like -22) and stick it into one end of the wire and then push the two wire back together with the wire going into both ends of the wire. Tape or heat shrink if there's room. Ig it's in the plastic trough it doesn't need to have extra insulation.
Excellent video - inspiring and informative to this 60 yr old woman backyard fixer of mowers people toss! Keep them coming. Thank you
Thanks for watching!
Your kind advice was just what I needed to replace the ignition coil on my trusty 20 year old SH85 blower. The business card worked great. I also did not mess up the spark plug wire because I was careful as you advised. Thanks so much.
I found that inserting the spark plug wire into the boot first, pulling all the way through then attaching the spring clip into the hole into the wire with pliers then pulling the wire back into place works much easier than trying to shove or push it into place.
I'm glad that somebody agrees with me about gas. Especially in these pre mix containers. I mix my own every time and it has yet to fail. Great work!
me too, at $ 5.00 to $7.00 dollars per gallon I would be out of business!
When I got my Sthil MS 170 ( because my Stihl MS441 is overkill for cutting small limbs/trees) the dealer where I bought my ms170 told me that if I bought the pre-mixed Stihl brand fuel it would extend my warranty by 2 years but for a 1 gallon jug it was $7.50. After they explained to me the benefits of the Sthil brand fuel, I decided not to get any I just mix my own and have not had any issues with the fuel itself, the issue that I have is a chainsaw doesn't seem to have enough power and when it gets hot it shuts off and won't start until it cools down. I've taken it back to the shop to have it looked at twice and was told there was nothing they could do. I insisted it could be a manufacturer defect or something of that nature and they told me that it was very unlikely.
@@jamesdrew8569 try $27 (£20) a gallon for stihl motomix here in the UK!!
@@SouthernStyle08714 Try running a compression check on your chainsaw.You could also pull the muffler off and see if the piston is scored.
@@GoldSeals thanks I'll definitely give that a try but the chainsaw is just a little bit over a year old but has barely been used so there shouldn't be any piston scoring but like I said I'll definitely give it a try
Love the videos! I watched this one and have a few hints: I work on tools (pneumatic) with a lot of pins and plastic housings and I found that a long punch or small phillips helps to line up misaligned housings and then just tap the pin in to push them out. Also screws in plastic go in easy if you turn backwards until they drop into the old factory cut track, this also limits worn and stripped out holes from overlapping cuts.
It’s a Stihl from my limited experience they don’t start easy. I bought My 55 husky in the nineties and it’s never had a carb kit just filter and plug. It always starts!
Great content!!
Keep them coming!
You gave me advice in a video to replace stale gas with Stihl pre mixed gas, it fired right up... THANK YOU, GOD BLESS.
Chick, your videos are excellent! I know that I'll see good, wholesome content without the distractions that so many others include into their presentations just to keep the observer's attention. I'm a Marine and I've also been trained for 30 yrs. in counter terrorism tactics. (retired) and just took a job as a small engine repairman of which I've had no formal training. My training comes from "RUclips U." lol. I'm old school in many ways, school of hard knocks. You, dear lady, have become my class professor at RUclips U. Your teaching technique and presentation have helped me tremendously. Thank you so much for getting me out of many unknown situations with as little pain, cost and time as possible. Keep up the good work, the good deeds and the good spirit. It was once said of teachers: "A fair teacher instructs; a good teacher informs; and a great teacher inspires!" You have achieved "great-ness!
Re. fuel quality , it's an easy test to put a small measured quantity e.g. a few cc or a 1/4 cup in a container alongside the same quantity of known good fuel in an identical container and do a timed evaporation test out in the sun .
If dodgy fuel has lost it's light volatiles this test will help show it up , check after a few hours and compare levels .
I was once given a Troy Bilt ride-on to fix that was backfiring and coughing and basically just wouldn't run properly at all , I ( finally ) did the above test and found that the fuel tank had been topped off with diesel fuel , it had enough petrol that it smelled not too bad but the evaporation test proved it .
Thank you so damn much! This happened to me yesterday (why do they make the damn coil so tight?!). I was about to strip the wire and try to reconnect just like this person did. I just pierced it back into the wire they way you showed and it started right up! I pulled the wire through the boot before connecting it though, so I didn't have to stuggle to get the coil back through the other end of the boot. We are tryly lucky to live in the era of the RUclips DIY videos, all thanks to content creators like you!
Chickanic's looking really cute ♥
When removing the high tension boot from a spark plug, give it a few partial twists back and forth to loosen the rubber's grip on the ceramic.
Lots of people still think plugs r made from porcelain lol
It's so highly unusual for a Chic to be an Mechanic, that's what makes your videos so interesting 🤔 you must've
Help your dad when you were a little
Girl 👧 and I must say your top-shelf
MECHANIC......REVVING VIDEO
9:17, nice boo boo lip after it wouldn't start.
🤣🤣🤣🤣, like a boss.
Maybe she helped her mom repair equipment and her dad stayed home and cleaned the house.
Thanks for all the informative videos you make, much appreciated! 🔧 💯👋
Same as Mick, I'm enjoying my first cup of coffee and a nice video this morning. :)
You make the process so easy to learn! Thanks again!!!!
Well now that was a interesting video and very informative. I own a Stihl chainsaw MS 311 just exactly like that one and now I know what to do, but I don't ever try to get that forceful with anything. I learned a long time ago that unless you know it needs a lot of force too much can get you in a lot of trouble.
Words to live by!
A quick tip for you and your audience: I have a Stihl string trimmer attachment, and the spark plug used to shock me in the elbow when I held the trimmer a certain way. I cleaned the boot with carburetor cleaner, then added several layers of tool dip/electrical liquid tape (both are made of butyl rubber dissolved into xylene), and no more shocks. The tool dip is sold at Lowe's as Plasti Dip. It's a LOT cheaper than buying a new ignition module.
my briggs powerd mower the boot was gorn every blade of long grass it would short back to ground cof and spluter weze and fart ..... i added polystyrene [ white foam box] in auto thiners till it made a puty chewing gum ? now i got a hard plastic cap now the strapping briggs runs as good as new like it did in the 80s POWER ON
Permatex black works too
@Chickanic, I own a Stihl MS211 chainsaw, and the carb/air filter cover vibrates off constantly when using it and has been doing so since bought new. Any ideas why? And how to fix it to stay on? It has a little section that is supposed to lock it in place, but it doesn't seem to work like it was designed... IDK ????
@chickanic: you imply that removing the plug wire cap assembly from the spark plug can be difficult but don’t show us how to do it. It may be obvious to some but could you explain it to the rest of us? Thanks.
Always enjoy and learn from this fine Chick!
I like to use dielectric grease instead of regular grease
Also with a q-tip put a little dielectric grease where the boot fits on the plug so it doesn't stick so bad
Very good video with great presentation. Subscribed!
Please forgive the spelling errors and grammar...spellcheck needs to go back to school.
New favorite channel 😍😍😆😆 hot woman fixing stuff gotta love that. Nice work 🏁🏁
Use 'shrink tubing' over the pronged section once poked through coil-wire (and apply heat {obviously!} )
Use WD-40 on boot to slide prong/coil through boot. Heat shrinking keeps prong from pulling out later on.
Glad I have a tube of DC4. I hear that there is a supply issue.
I have a Stihl MS 170 chainsaw with the same plug wire design. Oh yeah this happened to me too but was able to reattach it without needing major surgery. The saw is great, just a little disappointed with the design of the plug.
Thanks again for this video and wish you continued success with your channel 👍!
To be fair on this saw its quite accessable.. on some saws you need fingers like a doll
Good Morning Mick! Yup, the customer should had worked it off easier on this one. Have a great day!
@@Chickanic you too..
(Still) Stihl won't start!
It’s a easy fix for the person who knows what they are doing.
I’ve had them come off before I’ve never thought of trying to force the coil through the small hole on the boot the wire will barely fit on most of them I push the wire through the small hole and out where the spark plug goes then connect the wire like you did then just pull the wire back to where the loop goes and put it on the plug sometimes it’s easier to put the loop on the plug then slide the boot over the plug with the wire if the insulation on the spark plug wire is messed up it might be a safer way to do it without doing more damage also if the insulation is messed up after connecting the wire loop you can use some black light glue to reenforce the wire and insulation before sliding the boot over everything 👍
Just found the channel, looking forward to more vids 👍
When I find this problem ,I replace it with the clip type found on older briggs motors works ok !
Nice, I miss the days when you just unscrewed the wire into the ignition coil and plug.
Thank you Brea for showing this old man that I am not the only dummy who messes up the ignition wire by cutting it to so the end fits securely to the plug tip. I was totally frustrated that the oil wire no longer fit, but now I know... DON'T cut the wire... 🙄. Thanks for your great videos!
It's expensive gas mix in a can for people that can't mix there own .it's time to be self reliant great video
Completely right they've made them so tight I need a tool to remove some of mine ( spark plug )
Thanks ///UK
It's nice to see you starting the chainsaw properly !!! It really annoys me watching people drop starting their chainsaws. I think they enjoy busting their easy start springs !!!
Love your work ! Another simple quick fix. I have had issues with bad fuel here also. 😷
yes they are way tighter then they use to be, thats why anything of mine thats needed a new coil ive used the old plug wire on the new coil.
After seeing this, I'm definitely going to stick with mixing my own fuel.
It's recommended that you don't mix more than you use in a month. Pump gas just doesn't last like it used to, might as well be made in china.
@@killer2600 I haven't had any trouble with mine, BUT I only purchase fuel from the main Quik-Trip that gets a fresh shipment daily.
When archaeologists dig up the bones of medieval long bow archers they find the arms/shoulders are bigger on one side of the body because they’ve built up such huge strength. Hundreds of years from now archaeologists will be able to identify chainsaw repair people’s bones.
Nice Vid Brie, those boots are a royal pain. I do, however, remove the HT lead from bad coils and have installed them with epoxy instead of having to buy new, especially if the customer has a tight budget. Just an FYI. Keep the vids coming and stay away from those pesky nipples!!!
Get you spark plug cap in a glass off petrol about 5 min, and it will be 2 times bigger.
I’ve done that before my uncle has a motorcycle shop he sowed me how to fix the coil wire for the plug so I don’t need to take my equipment anywhere unless it’s severe
Excellent video however I would advise using only non-petroleum silicone grease on rubber.
Happened to me as well on a strimmer, lucky I am a bit dam handed at fixing stuff.
Please tell me you gave him the fuel back in the jar.
Does the lead not unscrew out of the coil like pro models
Good one, yes we see that a lot. Yes I agree I learned I only trust my own fuel, I know mine is good.
just found your page, looks like ur starting to make more videos, thats great!!!
Very good - clear no hype great educational content. Thank you.
Hi now back from my daily grind had the same problem with my neighbour stihl fs 450 a while back ,took a little moment and carefully fit back and as usual bad gas
Really appreciate this video! This woman is very smart a very good mechanic and certainly going places whether she knows it or not!
Great job I enjoyed your video!!!
Nice repair to the spark plug boot VERY CLEAR and I have one that needs a repair just like that on my mower THANKS AGAIN !!
Well unlike some of the trolls in the comments I DO NOT KNOW EVERYTHING. Thank you for your time and effort.
New subscriber. I've really enjoyed all your videos ! Thanks
Thanks for the anti-stupidity tip on the plug wire removal and the same kind of tip re: the canned gas rip-off. Do you recommend the use of non-ethanol gasoline ("pure gas") for small engine use, particularly with early 90s 4 stroke engines? Remember to change out the in-tank fuel line and filter in Stihl and other European chainsaws every few years, before they harden and crack, and refuse to start.
Ouch, that bad gas will leave a dent in the customers wallet! 💲🇺🇸 Roger
If you get two broken chainsaws you can save money on a rowing machine...
You'd have to pull the plugs so you wouldn't have to keep hitting the compression release (in the case something weird happened).
A helpful suggestion. After one gently removes the spark plug boot, one can lubricate it with dielectric grease. It won't affect the spark path, nor damage the rubber boot. It will make removing/inserting the boot going forward much easier.
Very usefull tutorial, thanks Chickmechanic!
Enjoyed,and learned a lot. Thank you.
Great info. Love your channel.
😘 even 3 years later , these are still useful🙂
Your video helped me fix my Stihl 170. Thank you very much. God bless you.
Great video! I have always just gone out and bought a new coil when I ruined boot. Hopefully I don't have to do this repair that often. Thanks!
Yes those canned gasoline isn’t always good!
Good video. I got rid of all my Stihl saws and switched to that Swedish brand for saws and Echo for trimmers and blowers. My Stihl saws ran great AFTER you got it started. I figured out that Stihl was named that for a reason. While everyone else is cutting wood, you are "Stihl" trying to get yours started. I have a John Deere 21S line trimmer, that was made by Echo that I bought in 1994. I use it every week and it has run reliably all that time.
Olá muito bom trabalho, nos aqui trocamos o cabo do módulo e fica bom usando o mesmo módulo
Great video, sort of a two-for-one on this one. I have had success digging the wire out of the coil and epoxying in a new one. What is your view on this repair? After all what is there to loose.
Never taken one apart…. Could you elaborate? Would like to know more. Thanks
If it works and saves money it's good
Older coils you could unscrew HT lead, and refit new one
spark plug boot pliers are a blessing i got mine for only 10$ and their USA made i believe they are from lisle. but great informative video keep up the great work and take care
if you buy after market coils get 3 of them because you'll be changing it every six months
Found this video after I bought the cheap replacement. Fixed the OEM. Got lucky with the cheap one. I bought the whole tuneup kit so I have extra parts now. I found sawdust and oil on my ignition contacts. May have been the problem. Not a fan of the MS250. I’ve used it for maybe 6 hours total using Stihl MotoMix only. I’m going to mix my own from now on.
@@mcraven8 not a fan of the 250 either , mine would run lean some days and to rich the next , did all the pressure and the comp. test and all was good , even with a new carb. it still didn't run right so i got sick of tuning and bought the MS260 as i should have in the first place , it's a much better saw built with better quality parts
Thanks a lot for the instructional video I have not heard that about the true fuels that you commented on but I will keep that in mind thanks again
Increased ethanol content in gasoline is having a bad effect on all sorts of small appliances like blowers, chainsaws etc..
NGK screw on plug boots are a life saver.
i know right! its 2021 and STIHL is using the same design as my cheap chinese 2 stroke HF generator. lol!
Great informative video! Just experiennced trying to replace a spark plug. I pulled the skins off and used make shift prying method. I see a comment said there is a tool. Wish you would have covered that. I don't see how any tool can get under boot with the tiny opening with the skin on.
