Easy to follow and thorough step by step tutorials do it yourself (DIY) videos to help you with your broken lawn and garden equipment including snowblowers and zero turn mowers.
I do my best to teach you how to easily diagnose problems the fastest, quickest and most efficient way with real repairs beyond just replacing a spark plug. These tips are for both the homeowner and shop owner.
Whether it be a handheld, two stroke, two cycle engine like a chainsaw, weed eater, weed wacker, string trimmer, grass trimmer, line trimmer, hedge trimmer, strimmer, brush cutter, leaf blower, or four stroke, four cycle units like a lawnmower, wood splitter, lawn tractor, zero turn mower, snowblower, pressure washer, generator or a ride on mower that needs parts installed or replaced, I’m your go-to guy.
My favorite brands of spark plugs are NGK and Champion and are the ones I recommend.
I’ve been a small engine mechanic for many decades and also run my own repair shop so my videos are loaded with tips and tricks that I have learned and want to share with you. You will also find many tool and product reviews from top brands on my channel as well.
I have the largest Small Engine Repair Video Library on UA-cam and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!

little additional tip...use heat shrink tubibg to hold the metal tab tight to the wire...works really good if the wire has some issues to hold it strong in place...i use wd40 for the boot to start it as well...
If you thread the boot down the wire till the ignition lead is sticking up and out of the boot you can then pull the boot up and over the sparkplug contact spring. That way you avoid the narrow end. Less chance the spring will come out of the ignition lead.
Had to replace the plug boot on my trimmer. The old boot was so tight I had to cut it off. My replacement boot had a smaller wire opening and I thought there was no way I could get the wire, let alone the metal lead, through the boot. Saw your video...the WD 40 was the secret. Took less than 5 mins...magical. Thanks.
Wow...we're talking 1940's concepts that are still relevant today. Insulating boot, good connectivity, lube, etc.
And the nasty job of getting that connector into the boot!
Interesting.
Thanks Dony!
Why not put the boot on the wire first going past the area where the metal contact goes and once you get the boot on put the metal contact on and then pull the boot forward?
Japp,gjort som du netimage10s.
Thumbsupp from Sweden.
I work on small engines everyday and always had problems with these but being honest with you I never thought of that one but most certainly will be trying it next time
That seems easier and the only way I've tried doing this. The hardest part is getting that wire to go around the 90 degree elbow, but its not that hard.
I was thinking the same,but the spark plug wire is very short & probably wont have enough length to allow for this.
I was "like" number 879, great videos Sir, Blessings to you and your Family
vary nice pro tip thank you
grouse stuff Donny mate and yep i do the same thing when i replace a clip on a spark plug wire and boot etc.
I put the boot on first and slide it over . That connector for the plug is a dopey design . I'm going to put a petrol hose clip over mine to keep it in place ,or I may even get a screw in cap .
Swiping up quickly I thought I saw someone holding the Stanley Cup in a thumbnail. Turned out to be a giant spark plug 🤣
Thank you. Mistery solved.
Another great job there Young Man
thanks Robert, have a good weekend!
@@donyboy73 you do the same thing.donny👍😎
You just saved my ass! Thanks
Great share ty
Boy howdy I hate that spring design. Same thing happened on my Husqvarna, which is already a horrible design to begin with as far as the layout of the ignition wire and having to remove the entire housing half to properly remove the spark plug boot (which in my case didn't even help). I wish the wire was long enough to just put a standard automotive plug connector on it and go to town.
anyone buying a new stihl saw should apply dielectric grease to the spark plug before they even start the saw for the 1st time or the plug cap will melt its self to the plug and cause these headaches when they need to change the plug
Thank s!!
The rubber boot has split all down the side on my sthil ms180. Do you know if all boots are the same if I was to buy one online or would I need to get a certain one? And does anyone know if I can swap the boot from a hedge cutter onto a chainsaw rather than buying new?
Can we use motorcycle or scooter spark plug cap instead of old one?
it's better to use the original cap
Dielectric grease is the best prevention to any electrical corrosion. On a machine, obviously.
why not slide the boot over the plug wire first and then install the metal clip into the wire and then just pull he boot over?
sometimes there's not enough room to do that
You would think they would invent a connection that wasnt this stupid
Who ever designed that spark plug clip needs to choose another profession.
What a shit solution, this with the sharp end of the spring that bites the wires! Due to vibrations (it happened to me with a Chinese chainsaw and a 4-stroke electric generator) the contact becomes imperfect over time! Couldn't they put a slipper to firmly tighten the end of the electric cable coming from the coil? We pay for bad solutions, with our own money!
Worst design ever....... breaks before it comes off the plug. (Sounds like Chinese engineering......)
I made the same repair on a different brand of chainsaw. The metal piece didn’t break, the operator pulled on the wire instead of the boot and the metal piece pulled out of the wire and the boot. To put it back together I lubed the wire and put the boot on first, then attached the metal piece to the wire and it was pretty easy to pull the boot over the metal piece. Another excellent video, thanks for sharing.
Another idea is to soak the rubber boot in a cup of boiling water first to make it more pliable and easier to slide on. Thanks for the great tips Don. 👍
Heat gun.
You help millions of people who are like myself that have little knowledge of these repair procedures.
Thank you for all you do.
All these years tinkering with small engines, yet I never knew about that coiled connector. I guess I have just been lucky. Once again, you have provided me with information so I can look like a genius to my neighbours!
This is totally wrong!! Pass the bare wire through the boot FIRST then crimp the spring and pull it into the cap, simple!!
That's kind of what I thought too! Good call man!
Depends on the shape of the boot mate!
This way never gets damaged btw...
Exactly what I was going to say. I guess common sense isn't so common these days
@@ΣΠΥΡΟΣΜΠΑΤΣΙΟΣyes the boot shape I have looks nothing like this one
Another great short tip! I like the idea of putting dielectric grease on plug. It's similiar to using anti-seize on items such as tractor axles so you can get the wheels off easily. I have struggled in the past removing older stubborn spark plug boots and have wasted my money buying a new coil / boot. Ugh! Thanks again Don!
WE put the boot on first .
Great design! Said no one ever.
Do not do it like this. This video is showing how not to do this properly. First push the boot down onto the wire and have the wire come out the hole where you press onto the plug. . Attach the spring clip to the wire. . Then pull the boot up and feed the spring clip into the boot. Done. ..
I feed the HT wire lead through the boot, put the spark plug coil lead on the HT wire, then pull it back into the boot (with lubricant).
I should have read the comments ... usually do but not today !
Can you slide the boot on the wire before putting the clip?
The biggest help would be if the manufacturers would use a better setup

Will this work on any power equipment? Like snowblower or mower
yes
Nice job 👍
Great stuff Dony!
Thanks for the part number Don, hope they are in stock!! Too many parts on back order, Briggs cams not til September? Not good!
yes I've noticed so many parts on back orders from Briggs!
Awesome video don! Hope your busy in the shop. Take care!
Stihl needs to change the Idiot who invented the ridiculously stupid "Spark Plug Boot" that is akin to a Chinese puzzle. I'm 71, I can change my auto plug wires ever so easy but as my fingers get older, that's not so easy.
Dony boy I owe you a beer! Thanks for this!
You pretty good at conveying information to a lay person, so I decided to ask a question. I am working on a motor from a chipper (Super Tomahawk) 1980s ? an H50 65484P Ser.# 4262D I need a coil but haven't been able to find out what one I need. Can you help? Thanks in Advance.
I've just got Stihl parts excluding boot to replace on new lead for my 1970's Partner.
That happened to me. But luckily it didn’t break the metal part. I slipped the boot on first then the metal part reinstalled the boot on the plug and used dialectic grease! That was 2 years ago still going strong! Thanks for the videos and all your help brother!🇺🇦☮️✌🏻
Thank you, You made it very clear how to do this. My clip came off the wire when removing boot from spark plug on Stihl backpack, I didn't know how to put it back together. Thanks again for the helpful video
Great Video ! ! !
However, is there any alternative to this stupidity? Whoever invented this system needs to go back to the 2nd grade and reeducate himself, try again. I'm gonna cut that P.O.S off and use a piece of wire twisted together, like the Cavemen used to do. At least I'll be able to hold my head up high.
Hello Dony Boy !!! Question for you ,different subject = help ????
I am looking for part number for the bolt that hold the gas bowl on Briggs and Statton engine
Could not find it to order ??? Oh i see the pictures every where but no mention about that bolt (jet ) part number
I have been through many sites and catalog and still not listed.
It has a stamped letter on it R or S ????
Any idea to help me ,also the little gasket with it ???
Thanks in advance
Serge
This video is excellent but never had a problem with older sort of spark plug cap. The first time I tried to remove the cap the wire spring clip (that fits over plug) was so tight (on the spark plug) that the other end of the clip came lose from wire. The design of this is nuts. In this age it seems this boot would be a solid part (with connector inside of it) that just had some sort of quick connect coupling to wire. This is a part that customers should regularly manipulate to perform regular maintenance and its frustrating that it turns what should be a 5 minute job into an hour or more job. Additionally, the manipulation to get the boot over the wire could very easily loosen the spring clip end that presses through the wire. The video is excellent but we should all demand better from Stihl!
Is this true for other brands? My husband Has a Ryobi Chainsaw and the spring and boot came off when taking off the spark plug
I'm rescuing an MS461 and today tracked it down to an intermittent ignition wire. At first I was happy to find this video but after piercing my finger once, pinching it hard with the pliers, I realized that this method is backwards. Haven't done it in many years and not on a chainsaw, but the boot really needs to go on first. When you pierce the wire with the spring contact, the boot then easily slides up and over the straight portion of the contact. The coil spring never needs to pass through the boot except for entering the large end.
Here I am ready to install a spark plug wire in the homelite st275 string trimmer , the boot was worn out top side shocking me. Come to find out after taking it apart the coil wire at the coil end doesn't have a boot it looks like it's been sealed inside the coil itself with some kind of wax. I never seen this before , do I change the whole coil out or is there a way to get the wire freed from the coil ?
ohh noo iv been there, don't get the cheap spark plugs they don't fit great. to tight and when you go to remove the boot again it will be stuck! those free spark plugs that came with that filter you ordered offline, toss that shit right out.
Good lord. This is what I've got. It's the dumbest design I've ever seen.
I have found a way fast way I use an old chain brake spring I have pinched the one end I slid the wire through the boot through the pinched end of the chain break spring and then just slowly pull it out once I get it out then I attach the metal piece and then slowly pull it back inside the boot
push the wire through the boot grab the wire with needle nose pliers and pull the wire out of the boot put the clip on and pull the wire back out of the boot
Why can't that garbage wire be replaced with a normal 90° connector?
Ridiculous how complicated these simple engine parts are, nothing is made to be easy
Thank you so much, was searching a while to find a video like this!
Donyboy - you are a legend! Thanks again for this advice!!
I lost fire on my weedeater, went to pull the plug and I thought the plug wire was done. I watched this video with a WTF look on my face the whole time- and wanted to think this video was about old, old engines. Nope. Bought my weedeater yesterday- this just happened. Am I only one in total shock that THIS is the technology we are CURRENTLY working with?? Jamming a piece of metal through an insulated piece of metal- hoping to touch the two pieces together and pass the electric through it? And it appears this is the actual industry norm. It’s almost embarrassing. As many DIY’ers, small engine, part time, shade tree, full time, and actually pro mechanics that there HAS been and IS- the ‘up and comers’, and THIS is the best we’ve come up with?? I quickly went to ‘I should build a better mouse trap..’ but honestly- I can’t decide on any of the 6000 ways to make this work I’d try to perfect! That’s all I got- I gotta go- gotta get dinner started and need to heat the oven with a stick and a rock….
I suppose it’s a good thing that it’s the ONLY electrical circuit and not that important to the actual operation of the firing in the cylinder 🙄
You shouldn't use petroleum based lubes on rubber. Silicone.
Such a crap design. Drives me nuts when bean counters and engineers have “great ideas”
Hi Dony, where is your shop located in Toronto, what the address?
Just the info I needed! Thx. So, if there is room to put the boot on first then slide it up, would you do it?
I HATE vampire wires, why does STIHL use these stupid things?!
Excellent video and thank you for taking the time to create this tutorial.
Both my Echos do as well. We're talking frikn prehistoric technology at its finest
Love the intro and positive energy Don. Awesome video on this repair (with the technique and tips to make it easy). Hope you and your family have a great weekend. Celebrating the July 4th weekend here in the States.

Thank you so much this video really helps
another awesome video, dony! other repair guys get puzzled out i replace boots and spark connectors and I always have a hard time explaining myself. you do an amazing job in explaining your repairs and diagnoses.
Dony, you are the Best !Thank you again....
Thank you very much - just helped me out :)
push boot over wire make repair then pull in
There ain't no way that spring gonna fit in that plug
It's very useful and specific
You make the job at hand look very easy,thanks you for your video clips
Great instructions, will be helpful for many.
I have always just bought a whole new wire. But i can see why this could make sense as well. thanks for sharing
Couldn’t you use a connector and boot from a car? That’s what I did on my snowblower.
yes you can but the small engine ones are smaller
I had this issue yesterday, said eff it and soldered it
great video! Thank you Sir!
Thanks so much for the clear helpful video. I just pulled mine loose while getting ready for the next season.
Bloody brilliant buddy....thx.
dielectric grease is non conductive.
Is this the same on a snowblower?
sometimes it is not that easy even with lube
BINGO! Thanks this is EXACTLY WHAT I NEEDED! And I have a contribution to everyone here! Take the boot and drop it into a cup of hot soapy water for several minutes. The rubber will loosen up and it will SLIP EASILY RIGHT OVER THE SPRING AND WIRE! You wont have to fight with it at all!
Thanks for the tip Don.
Happy Canada day. Enjoy the long weekend 👍
thanks Peter!
Donny 73 me and my boy were in Ontario Wednesday thought making contact with you ran out time
nice!
@@donyboy73 im not the one just drop in on some with them .lol
We use hair spray, it is slick and allows the wire to slide in, then when dry is solid and helps hold it in place(put in correctly it usually doesn't need help though)
Thought I needed to buy a new part but again UA-cam and Donyboy73 comes thru. Thanks for posting this easy fix. Saw fired right up.
Thank you!
Did the old spark plug actually need replaced? I typically clean spark plugs using a wire brush, then see if there is a difference in starting and running.
Thanks brother for that
They started using those spring connectors on the spark plug leads and that's
what's screwing everybody over. I ground off a few thousands from my spark
where it connects to the lead. Now the spring goes on and off no problem.
Great video
Thank u very much!!!!
