How to Easily Fix and Replace a Spark Plug Boot 

Excellent news Michelle, glad I could help solve the problem

You're welcome Matt, thanks for watching

Just saved me another call to hyundai customer services , cheers ,I broke my recoil starter then broke this putting on a replacement 😢

You saved my life too! Thanks from Australia!!

Thank you Chuck, really appreciate your comments and so glad that my video could help you.

I know that feeling very well!!!

Lol 😂

Good news! Same thing happened to me. I spent hours working to find the fault and pretty much the last thing I did was check that little spring

So pleased it could help you. I actually did buy a new trimmer and then found the problem, so now I have two:))

You're welcome Jimmy, so glad that the video helped, thanks for the feedback

Glad you found the problem Hugo, although 5 years is really not that old; these days nothing seems to last

Great tip, thank you, pushing the "L" through the insulation is definitely a mission

True that Rule

@@davekennedy52 still both work ! Thanks for the tips guys !

Surprisingly enough, that little spark carries quite a punch!! Glad you enjoyed the video.

you're very welcome! Glad you found it useful

Love a story that ends well! Thanks Kevin, glad the video could help

you're very welcome dakota, so glad the video helped

Glad you enjoyed the video, Petster, I agree it seems quite a primitive method, I'm sure it can be improved on.

So glad that my video could help I agree, they should make them more robust because people remove the boot and spark plug many, many times for cleaning and for any ignition problems

thank you Edward, I agree and I think thats the reason why so many people are having this problem, they're pulling the HT wire and not gripping the boot to disconnect from the spark plug. Some of those springs are excessively tight!

I know that you can send stuff back to Amazon if you're not happy, but I've always found that a bit of a nuisance to do. So I'm very glad that the video helped you

Thank you Paul, so glad my video could help, I had no idea what an Auger was until I googled it and then realised that I had bought a manual one just 2 months ago to put in a few posts around my wifes rose garden

Hey Mark sorry for late reply, glad you enjoyed the video. Yes, South African accent, very noticeable😁

and I'm sure that ruined your whole weekend, !! very glad that the video helped, thanks for watching

Yes, absolutely, it makes all the difference

Glad you enjoyed it Aaron, I'm sure they could improve on the design, lucky its a quick fix

Husqvarna 128RJ sting trimmer has same design. Thanks for the info 👍

Nice to know Wes, thanks for watching

Really happy that it worked for you and well done for not giving up on your trimmer.

Glad I could help, don't worry, I do a lot of yelling as well

Thank you Mike, glad you enjoyed it. If thats the Honda, its a really nice looking bike

Glad you found it useful, Roberta, hope it worked for you, thanks for watching

@@davekennedy52 Yes, I was actually able to get my 27 year old mower up and running again thanks to this video. I'm so glad you took the time to post this!

Its a pleasure Thomas, glad I could help

Well I hope this works for you Marty, good luck and thanks for watching

Dziękuję, bardzo się cieszę, że mój film mógł Ci pomóc i rozwiązać Twój problem. Dzięki za oglądanie

Hey Wayne, you just made my day in more ways than one!! Firstly, glad my video could help and secondly nice to hear from someone who can "gooi die taal" Dankie and lekker bly!

@@davekennedy52 bloody strimmer was literally brand new and the coil parted ways so i followed most of what you did and hey presto, Bob is your mothers brother! Lived in SA for 6 years before getting hijacked in 2002.... missed it terribly since! Head of the Irish Clutchplates!

Sorry to hear about your hijacking. I was so tired of living behind burglar bars, electric fencing, securit gates and armed response. my car was broken into about 20 times in 5 years. Moved to France in 2008! Don't know what make of strimmer you have but I have a problem with a new McCulloch. Yesterday it died for the 3rd time

Thank you, its something that most people overlook, so glad the video helped

@@davekennedy52 I still have issues to fix it seems. It only runs on choke and bogs down when I throttle. I hope I can fix it today with a few adjustments rather than anything more advanced!

@@gommechops I have the exact same problem today on my chainsaw, very frustrating!

you're welcome John, glad you enjoyed it

You're very welcome, glad you enjoyed the video

Thank you and you're welcome Gareth, glad you enjoyed it

Good to know Steven, glad that my video helped, thanks for watching ((

So glad it helped and you're welcome, , thanks for watching Charles))

Glad it helped Jeff, no, definitely not a twist off

Glad you enjoyed it Dennis, thanks for watching

I'm sure you could! thanks for the suggestion, my solders are never strong enough

That’s what I did. Fixed it!

@@JayTdub13 Fantastic! Well done

To solder or not to solder? Ask yourself, Are you A; Do you want the job done correctly, eliminateing any possibility of future issues? Or are you A ; Wannabe fixit man and take the chance that NOT soldering the most important connection in a internal combustion engine is a intelligent choice, that will not cause future engine troubles.

very kind of you, thanks for watching

Glad you enjoyed it NM and very pleased that it could help you, thanks for watching

Couldn't have said it better myself, Recently had a 2 year old CD player that stopped working. I was told to throw it away and buy another one. Glad you enjoyed the video and thanks for watching

Thank you John! Yes, my boot is very flexible even though its about 40 years old. I think the new boots have a plastic/rubber type of material and are definitely more rigid. Glad you managed to fix yours

@@davekennedy52 Yeah, but (as I responded elsewhere since then) ....Turns out there is something wrong inside the 6" ( ?) of ht wire. It's moulded into the coil, which are cheap enough but a) the principle of the thing, b) month by slowboat from China. Looking at doing a splice but didn't realise how THIN the one strand of wire is inside, and DELICATE! I can't find anything on what the anatomy of an HT lead is. The pointy end(s) of the spring coil that fix into the rubbery insulation have no chance of actually hitting the central wire. And by poking probes along the lead to find a place where there is continuity with the body so I can make a splice I think I've destroyed the actual wire! Hey ho!

@@johncollins8304 I'm very surprised to hear that the wire is so thin and fragile. Mine were quite thick. I'm sure you could use the spark plug cables from a car if you are able to splice them. I had the same problem with that pointy end of the spring. I wasn't sure if it was touching the inner wire and it just wouldn't stay in place-kept popping out again.Really irritating to wait that long for parts

You're welcome Rocky, glad you enjoyed the video

you're very welcome j3, glad you enjoyed it

Glad you enjoyed it, Panzer, thanks for the comment and for watching

Ha! LM can't think of a better way to spend the day and glad you enjoyed the video:)

You're very welcome Michael, glad you enjoyed it

Thanks TJ, very pleased that it helped you

sorry for the late reply Thao, glad you enjoyed the video

Very kind of you William, glad you enjoyed it

Plug leads on chainsaws are usually very short. Good luck, thanks for watching

You're very welcome, glad you enjoyed the video

you're welcome Teng hope you found it useful, thanks for watching

You got to expose the inner wire, so cut back the plastic covering, then reattach the exposed wire to the coil spring in the boot. Then put in a spark plug and turn your engine and if you see a spark then your connection and wire are still good. Hope that helps

davekennedy52 thanks 😊

Mine is the same did it yesterday never Said there was a spring in my stihl Fs- 56 can’t do what u posted up not enough wire

Thanks Deosie, I've also noticed that on the newer grass trimmers leads, there's not a centimetre to spare. Chainsaws are the same. Hope you find a solution

Glad you enjoyed the video Christopher, yes I have the same problem!!

Glad you enjoyed it Sik, and thanks for watching

You've been doing it right!! The point kept on slipping out of the wire on my machine. I continuously had "no spark" issues. Now I don't have to worry anymore. Thanks for your comment

You're quite correct, but mine wasn't making contact and kept popping out so I had to make an alternate plan

you're very welcome, hope it helped and thanks for watching

You're welcome Krista, glad you enjoyed it

Thanks for watching Shin, glad you enjoyed it

Many thanks ernest, glad you enjoyed it and thanks for watching

Thanks Paul, glad you enjoyed it

you welcome Asanka, thanks for watching

So glad you enjoyed it Jeddie, thanks for your encouraging comment

Groot plesier Willem, thanks for watching

Yes, you can insert the hook of the coil into the HT wire, thats the correct method, but in my case the hook kept coming out and it wasn't making contact with the wire

@@davekennedy52 Thank you. My spark plug boot ripped when I tried taking it off so figuring out if its a simple buy fit and plug or I got to get more involved.

Hi Steven, glad you enjoyed the video, thanks for the comment and for watching

Thanks Roger, glad you enjoyed it

You're very welcome E-Rider, glad you enjoyed it

Thanks Douglas, I know what you mean, I have a lawnmower spark plug cap thats held together with insulation tape, keep on meaning to buy a new one

This one is for a weedeater/grass trimmer, I'm sure your one looks a lot different but its purpose remains the same

Ohh okay thank you so much

@@Wet_Soap You're welcome, love your rescued snail by the way😀

Awwww thank you

Glad you enjoyed it, Victor, thanks for watching

No problem Atul, the spark plug cap is there just for insulation

@@davekennedy52 but motorcycle cap size doesn't match with spark plug of machine

@@atulshinde5212 if motorcycle cap is too big you can use insulation tape to keep it in place

@@davekennedy52 it's smalk

Nice to know Mark, thank you, the McCulloch I've been working on has a sealed boot and very short lead. Had to replace the coil and the new lead is actually too long

no words for you barney boy, nice try

Glad you enjoyed it, thanks for watching

Thanks Justin, glad you enjoyed the video

Solder? Probably more permanent as well.

terima kasih, merci beaucoup

thank you mrcabojr,appreciate your comment

don't worry Logan, happens to the best of us!!

I can see that could be a problem, my chainsaw lead is also very short. I've heard of a spark plug wire splicer (I think they sell them on ebay) Then if you have some spare cable you could just join them together with the splicer., and make your lead longer

Hi Steve, that is a regular 90 degree boot for a coil. Some of the newer ones are sealed units. That coiled spring is what grips the top of the spark plug and is supposed to hook into the HT cable. Not a clever system at all. Thanks for your comment and for watching

@@davekennedy52 I mean a 90° end like on a car plug wire

, thanks, I see what you mean, it would certainly make life a lot easier. With the present system, people tend to pull on the HT cable to remove the boot from the spark plug and I think thats what causes damage

​@@davekennedy52either way I'm glad you didn't try to push that clip threw the small end of the boot like a lot of videos on RU-vid 😅

Absolutely!! Keep well Steve

Thanks Swiftbobber, 2 years ago I visited my sister and brother in Auckland, beautiful and friendly country,

Yes, I've noticed that the newer strimmers don't have an inch to spare. Just replaced the coil on my McCulloch and the wire was actually too long!!

I know how you feel, it happened to me too!!!

@@davekennedy52BTW then I have to redo and 2nd time it worked better and this no longer happens. At least 5-7 times in the row I was able correctly take off and put it back and it is still works.
