Easy to follow and thorough step by step tutorials do it yourself (DIY) to help you with your broken lawn and garden equipment including snowblowers.
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, 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 CZcams and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!
I want "DON THE SMALL ENGINE DOCTOR" on CZcams to save you time, frustration and most importantly, MONEY with my HOW-TO videos!

I have a Craftsmans 17 HP riding mower. I tried what you suggested. I pulled the spark plug and it turns over. I turned it over for at least a minute. I put the spark plug back in and it locks up again. Repeat and it does the same. Any suggestions
here's repair solution in this video czcams.com/video/T1anxdNWf5Y/video.html
@@donyboy73 Thanks very much!!
Thanks for the great video, learning here.
The only guy on CZcams who is clear, direct , and simple. Thank you.
Right? Many can do*, but few can explain well.
*And many CAN'T even do well -- ahh, CZcams!
DUDE!!!...You are the man!!!...tipped mower up to take blade off to get sharpened...forgot to put mower back down...2 days later put blade back on...and ran into the hydrolocke...but never heard of it...was resigned to scrapping the mower...but found your video...10 mins later...BINGO!!...thanks alot...saved me a few hundred bucks
+Mike Scott you're welcome mike, make sure you're subscribed
Thank you from a single mom who has been learning alot about this lawnmower this year, (bought it couple summers ago and this summer it acts up) but have been able to keep it going thanks to this video for the most recent fix!!
You sure saved a couple of senior citizens a very costly trip to the small engine shop. This trick worked great on a Craftsman 6.5 hp mower we accidentally poured too much oil into.
I remember watching this video when it was new lol I was 11 then your one of the people that got me into working on lawn mowers because of working on lawn mowers I know how to work on atvs and gokart and motorcycles and now of course being 17 I have a truck so I learned to work on it. I probably wouldn't know how to do any of that stuff if I hadn't come across your channel and learned the basics of engine repair. thanks for what you do🖒
Donyboy is one of only a handful of good mower/small engine repair guys on CZcams. Thank you for your hard work and insights. You have literally saved people thousands upon thousands of dollars.
I have 9.5 hp wood chipper that had not been used for 5 years. Would not start. Pull handle froze. Found and watched your video. Followed your instructions and freed up the freeze and fired her up! Thanks!
I made this mistake yesterday not thinking properly. I overfilled my lawn boy with oil. Man. Thanks for tips. I love your videos. I have learned a lot over the years from your videos. Thank you!
Aw, beautiful! I stored my lawn mower upright for a couple of days to fix a cracked gas tank. The lawn mower shows the same symptoms of the pull cord being tough to pull and it won't start. I'm going out right now to pull the plug. I'm sure you nailed the issue.
This video is the only one on CZcams that clearly explains the problem.
Many thanks!
This is the 3rd video of yours that I’ve referenced today to resolve back to back issues.
Not all heroes wear capes. Thanks you for what you do.
It is rare to find help for the exact problem I have(for me at least :/ ). This happend to a pressure washer that tipped over in my truck.Almost lost the job. This is not the first time you have helped me Dony. Thank you so much for doing these, being clear and easy to follow.
Thank you Dony. I overfilled my chipper with oil. I found your video, removed the spark plug and the oil came pouring out. Was able to start and am now back in business. Outstanding!
This worked on a new snowblower. I brought it home tipped on its side to fit my car. I think the oil migrated to where it caused the hydro-lock. Would not crank over at all. Pulled the plug and then it could crank. No oil or gas came out. Put it back. Ran very dirty for 10 minutes, then fine. Thanks.
2024 here. This vid was spot on. Thanks man for keeping it simple & to the point.
I followed your instructions and it worked like a charm. Thanks you saved me from an unnecessary expensive repair bill.
This worked exactly as in the video. Removed spark plug, pulled the starter about 20 times, wiped off the spark plug and replaced and mower started on the 1st pull. Saved me the $250 I was about to spend on a new mower. Thanks!
thanks man! you're a life saver. borrowed my neighbors tiller, same symptoms, tried to pull start and nothing! followed these steps, smoked out my neighborhood and now I'm good to go! lol. thanks again. saved me.
thanx. most u tube guys don't really plan their videos very well and give us WAY, WAY too much info and wast viewers time. you done 👍
thanks, make sure you're subscribed
I honestly was about to bin the Honda GX200 I only recently bought second hand.
But you explaining about the oil, my engine must have rolled around in the back of the car.
Watched your video about 15mins of pulling and the pressure smoothed off and it kicked into life, the garage looked like it was on fire with amount of smoke!! Lol...
Cheers for your straight and simple vids.
No graphics or gimmicks just straight to the point! Nice one 👍
I agree with the rest of these comments. You are one of the best MUTT's around (Multi Use Technician and Trainer). I would add, check the oil level and bring it up to the correct level before starting.
Thank you so much for this video! We thought our lawn mower was toast! It is running like a champ now and the grass is cut! Great instructions and great video!
I'm an old man and needed the hand. Thank you very much.
I TRIED YOUR METHOD AND IT FIXED MY PROBLEM AND WORKED GREAT.THANK YOU FOR YOUR VIDEO'S THEY ARE CLEAR AND EASY TO FOLLOW.KEEP UP THE GREAT WORK.
Hey man Thanks, I just changed the oil in my mower, ran it for about 10 min , came out today and it was froze, went out to buy a new one, couldn't find one, searched the web as a last ditch effort and saw this!! You just saved me 400 bucks, you rock!!
Thanks, I picked up a MTD yard man mower at a moving sale that didn't run. It was only 3 yrs old. After discovering it was over full of oil by a lot. I did just this I. Addition to draining some oil out and new plug, it worked fine.
you are a great teacher thank you
This happened to my mower a few days ago. I used this technique and got it cleared, and she started right up. Thanks for putting these out there.
Don't forget to check the oil level. It may be low after this procedure (or high if that's what caused it in the first place)
Great video! Short and to the point and I fixed my mower in 5 mins! Thanks!
You Sir, are my new God...lol I have subscribed, and of course liked your video. After searching for answers for days on the tube and everywhere trying different things I came across YOU, I knew right away, THAT'S IT! I went and did just what you said on a 1.5 yr old Toro that ran when I put it away for the winter and was frozen. I cut my lawn today and finished just before the storms are hitting and the building dept crawls up my tail. Thank you Thank you Thank You!!!!!!!!!!!!! YOU ROCK!
I had to do the same thing one day but didn’t need the quick start. I also managed to set the thing on fire another day by tipping it the wrong way while mowing on a steep hill.. Live and learn. Great video, thanks for the info!
Just came across a 22" weedeater at the end of a driveway... So far it will need two screws and a governor spring! The folks at Briggs sent me out the parts diagram for the engine! Can't wait to try firing it up!
I know nothing about small engines. This was a giant help. All I knew was my pull cord wouldn't pull. .... right after I had tipped over the mower to clear it of grass. So everything you said and explained made perfect sense. I took out the spark plug, and sure enough the pull chord suddenly worked and shot out a ton of oil with the first pull.... but none of the rest. Good stuck, thank you :-)
Thanks for this video. I couldn't get my mower started today and knew for sure this was why when I watched this. Its running great now.
This has always been one of my favorite repairs. Always a quick fix, especially when a careless lawn crew doesn't close the fuel shut off before transporting a long distance or on the highway. I also make sure to change the oil if fuel is in it at least twice to get all the gas out of the crankcase and not damage any internal components, especially the aluminum connecting rod.
very nice, you almost sound like a shop teacher. very calm and clear in what you say. i just subscribed and am looking forward to seeing more. thank you
Thanks for the video. picked up a lawn mower from the side of the road and got it working because of your video
Thanks Scott from Toronto
You gave a great description, on how to fix this problem. Thank you.
thanks this can be a help to people one time my friend had a hydro locked lawn mower and he got rid of it thinking the engine was blown
Yes you have remained thorough in your videos but yet u make it where us diyers can understand. Thanks Dony boy 73. And thanks 4 u tube. For allowing us to be able to see his videos
Don't forget to check the oil level afterwards! Great video
Thank that’s exactly what happened after tilting my mower and seeing oil pour out of exhaust. Concise presentation sir !
Had this happen to my pressure washer today. I saw this video many years ago. Saved my butt.
Right on. I had a B&S engine on a rough cut mower that I couldn't even pull the rope on. Yes I stored it over the winter up at about a 45 degree angle. After removing the plug; pulling the rope to force out all the oil above the piston; checking the crankcase oil level, cleaning the plug off completely with denatured alcohol and drying it, it started right up.
Just to say thankyou so much for this advice. Was about to scrap my ride on mower.
Perfect instructions, tons of smoke, fixed in 5 minutes. Saved me $100+ and several hours of dealing with the sleazy lawn mower repair guy. Love youtube EDIT: And this video is 5 years old still saving our ass tons of cash. thank you forever
This worked great. The video was concise yet still gave all the information needed. You've allowed my 14-year old lawnmower to make it to 15.
I had the same problem, it was hard to pull and I left it standing upright in the garage. Quick Google search and I found this video, 10 minutes later I was mowing the lawn!
Thanks for posting this! Worked for me and saved me a trip to the shop.
AFTER WATCHED YOUR VIDEO , I DO THE SAME TILT THE MOWER UNTIL OIL CAME OUT MOST OF IT AND REMOVED SPARK PLUG CLEANED , FIRST TRIED IT STARTED LOT OF SMOKE CAME OUT BUT NO LUCK . TOMORROW WILL GET DIFFERENT CHEMICAL CLEAN OILED WET SPARK PLUG AND TRY AGAIN . THANK YOU SO MUCH .
I got yard machines push mower with the big back wheels from a guy today for $10 this thing is like new. he said that the engine was blown and locked up and oil was coming from the muffler.it was hydrolock just like the mower in your video and he put way too much oil in it .mower runs great now after doing the same thing you did in this video .now ill sell it on Craigslist for $75 thanks a lot .
Thank you very much. I am learning a lot from your videos. Keep up the good work .
tualex67 thanks
I have that same push mower for at least the last 8-10 years, excellent mower. Great vid!
Excellent tutorial. I couldn't get any ether into the engine to get it started, but after a few attempts, I was able to use the primer bulb to squirt a little gas in it to keep it going.
Donyboy73, What a time saver! For the most part, your videos are always short and sweet. I am smiling so hard right now, you're the best!
thanks lol
I did these things, and the pull cord works when I remove the spark plug, but the mower wouldn't start. What now?
you may still have oil in the cylinder, you may have to repeat the process
I forgot to add that when I did put the spark plug back in, the pull cord wouldn't work at all. Nevertheless, I will keep repeating the process for awhile.
donyboy73
Thank you for taking the time to post this video. I was thinking for sure I locked up the engine, but I stored the mower up just as you noted and that was my problem. Thank you!
This happened to my pressure washer today, and generator sometime last year.. haven’t tried to fix either yet but glad to know that this problem has a solution- thank you!
Thank you for the helpful video, ended up gettting the lawnmower running and i burned off the oil like you said and its running great!
You’re a lifesaver today. Over oiled my tiller. Thanks
Thank you a thousand times. You just saved me $200.
princez413 you're welcome
Your neighbors are going to love you.
My Honda mower is doing the exact same thing, you might have saved me a trip to the overpriced repair shop! Thanks!!
You bet!
Don't forget to let it sit and Check the oil level before starting
-
looks like safety switch is cut of under the seat,it truns over when I jump the solenoid,I really appreciate it dony thanks bud,for ur inputs
Thanks a lot. I knew it was not the spring. So kept Searching you tube and found your video. I have same lawnmower and has oil coming out of muffler. Saved me a lot of time and aggravation.
Just fixed my lawnmower thx to your video! Thank you!
Hey thank you so much for this fix. exactly what my problem was and saved me a trip to store for repairs. much appreciated
Thanks for sharing with us!! I skipped the starting fluid step but it started right up
You learn something every day. This worked like a charm on my machine. Thanks man...
Great clear video of how to do this but I would add some safety tips. Because there will be someone who does this badly, maybe encourage the use of a dust mask, goggles and clean up the excess oil & starter fluid before starting the engine again. Other than that your clips are the best to follow.
Another reason why I'm glad I subscribed to your channel! From a fellow Canuck, THANK YOU!
great thanks my mower is the same as the one shown, and had the same problem, runnin like a champ now , thanks.
Great job donyboy73 your a awsome small engine doctor.
100% on the money. Just saved an MTD at the curb with this exact problem. Oil level was too high, saturating the air filter. Corrected the oil level, replaced the air filter, and changed the plug for good measure. Also had to pop the butterfly free, mine is the fresh start no prime system Briggs. After doing that, the mower runs like new. My neighbor was shocked. Lol. Said he did not need the machine, got an electric one. Yea right. Lol.
Okay, I don't know who you are, but I just used your video to fix my "hydro-locked" power washer in about 23 minutes, so as far as I'm concerned, you Sir are a f&(%!ng genius! THANK YOU!!!
don't forget to check the oil level before starting up in case its now low!
thanks for the great video!
like the old saying goes, you learn something new every day.
I can see how happy my Toronto neighbours would be starting that up!! haha
Thanks for posting this! I had exactly the same symptoms on the engine on my leaf vacuum, and this method helped me to get it started. Good advice! Thank you again.
+taratupa73 YOU'RE WELCOME, MAKE SURE TO BE SUBSCRIBE
I had this happen and through an hour of Internet searching I finally got it going by removing the spark plug and forcing the flywheel with a pry bar to get it moving again but it's run flawlessly since.
This is a highly motivation to every one! Like you said, Ill dump my lawn mower due is not working but many time is an easy solution! Keep posting videos on that way, congrats bro....
you're welcome bro
Thanks very much Dony. Worked like a charm. Saved me time/money in the repair shop. Much appreciated!
Thanks for the video. After trying several other things from other sources, simply clearing out excess oil in the spark plug like you showed solved my issue as well!
i am originally from northern ontario canada, it's a french accent
Always watch your vids when I'm having trouble with a repair. Thanks my guy
I've come a cross this now I know watt wrong and watt to do thanks your just the top at watt you do Donny.
I give you five stars buddy.
thanks man
Thx for the VERY useful tutorial. Good job.
Thanks for getting right to the point. my lawnmower is up and running
Thank you, just what I needed when I screwed up my pressure washer oil change 🤦🏻♂️
Direct and to the point! Thank you
I agree with what some of the other’s comments, clear, precise, and straight to the point.👍🏿04/30/2023
I finsially fixed my dad's mower thank you ! He beat me for days because I broke it
Thanks a lot. My issue was just solved without spending $75 or waiting for days foe the issue to be fixed. It didn't take me a minute. :)
Oh - thanks! So, you think the problem is with the carb? Does it require a complete rebuild, or can I replace those things just by removing the bowl? If you can't tell, I'm a real novice at homeownership and small engine repair. I inherited the riding mower from my folks and they dropped it off at my house, so I don't even have a trailer to take it to a mechanic to get fixed. I really appreciate your help.
I tuned up a mower for a neighbor, they used it for a week and brought it back complaining that my work was shotty, so I took it back and found out from the woman, that they store it like you showed in the video, it did the same thing the one here did, I told the lady it wasn't my work that was at fault, it was the way she was storing it, and she should store it level, she did, and thanked me, and she brings her mower and her families mowers back to me for seasonal tune-ups now.
yes happens a lot lol
oh yea god bless you for helping people.it seems little but it sure made my day..May Yahweh's light shine fourth and bring you blessings.Amein
my neffew hydro locked my new minibike I thought it was toast till I saw this video very good job thank you
Hey thanks so much. I was working on my generator and turned it on it’s side where it was leaking oil. Then this happened, now I see why.
