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 TH-cam and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!

Thanks again you are the best small engine repair teacher.
Perfect timing, just had to get my snow thrower out after 3 years of not being used and it was flooding. Just saved $100.00 in repair cost! Thank you 🙏!
Hey there Dony!! Great tip. I didn't even know this vent hole existed. This will help me a lot!!! Take 'er easy!!!
Wow! That is something I never thought of. You are truly the sorcerer of small engines! Thanks for all you do.
Such a tiny vent, on a piece that’s exposed to the elements all the time. Very surprised they don’t clog way more often. Thanks for the tip and vid Don. 👍🏼🇨🇦
I am glad that I saw this video and I have a generator which I never used, and it have a Tecumseh carburetor on the unit. The unit has been sitting for so long until the unit need to be checked before trying to start it again. Thanks for sharing this tip with us all.
Dony, you are THE MAN. Had the exact problem described in your video. Found the vent hole and cleaned it out with a small wire Thank You!!
The power of knowledge. Thank you for passing it along Dony! Cheers good sir!
Great video!!! The carb on my snowblower had fuel pouring out of it, and nothing I had tried affected it. After trying a carb rebuild kit, a thousand float/needle adjustments, and a million curse words, I found this video. Turns out that the vent hole on my carburetor was plugged.
Cleaned out the vent hole, and NO MORE FLOODING!!! THANK YOU SOOOOO MUCH!!!
FYI - I used a 0.6mm dia (.024" dia) micro drill bit.
The thumbs downs must be from small engine repair shops.. Great video learned something new today!
for sure lol
That little vent, and the tiny jet on these carburetors must be small engine repair shops best kept secrets. I never knew about that vent and i've been working on them for 20 years lol
Learn something new today.
My carburetor stopped running on me and started flooding until it emptied out the gas tank...made me wonder why!!!! I'll try to locate the vent hole(s) and cleaning.
Probably thumbs down for pronouncing the name of the engine as Tecumsie..
Great tip! Been working on these carbs for years and never even knew that vent hole was there, thanks!
You give us so much info and hands on . It's great . Thanks
What an absolutely great tip... This was my exact problem even after rebuilding the complete carb (including the float needle and seat)... Thanks again donyboy73!
Thanks so much. The carburetor on my Toro Snow Blower has been leaking gas, giving me fits. Watched your video and took your suggestion of checking the float. It was filled with gas and causing the leaking. Problem fixed thanks to you. Thanks again from DCA in North Michigan, USA
My father in law had John Deere redo this carb almost yearly for this. (too bad no TH-cam 30 years ago) I ran it dry until friend said not to. Then it started happening to me. Had a shop redo the carb 2 years ago. Ran great that year, Got it ready for winter today and gas all over. Couldn't believe another needle and seat; TH-cam is go to reference, and between DonyBoy and Taryl have been fixing the toys myself. Would have spent 85 bucks for a 5 minute repair. THANK YOU THANK YOU THANK YOU!!!!!! You guys are great!
Great tip, thanks for sharing! I enjoy your videos
Great tip. Fixed my leaking carb. on my old 5 hp Craftsman snow blower. I had spent hours replacing all the seals and gaskets, and it still leaked. Poked a bristle from a wire brush into the hole as suggested and the leaking stopped. THX so much!!
You helped me alot with my antique troybuilt horse tiller with a Tecumseh engine
You saved us a ton of $$ from "The Shop" mechanic fee. Great tip! Thank you!
good tip, great photography and editing. thx
Thank you, clearing the vent I didn’t originally see fixed issue.
Thank You for the information, I never realized there was a vent hole there. I hope that holds true for older 5hp carb, I did the auger upgrade and it was working well till it started leaking gas second time out. That little blower really throws snow well when it runs correctly, even in slush at roadside.
Thank. You
Thanks for the great tip! I have this carb on my 10hp Yardman snow blower and it has been leaking fuel out the carb even after changing the float bowl gasket. I have to check this pin hole.
Great tips, Don! Thanks!!!
Great tip Don, thanks for sharing.
Cool info ! Thanks for sharing.
great as usual, appreciate your channel
Great Tip !!!!!! A lot of people condemn those carbs , but I have found they are as good as any others if they are clean .
wow! This was such a big help I can't believe that that tiny hole cause my fuel leak. I checked the float valve but it was good. Then I stumbled upon your video and fix the problem with the carburetor on the blower! Thank you thank you thank you.
Great tip Dony!
HOLY WOW! THANK YOU! I will check this later today. My blower chugs and leaks. Sounds very familiar! Great tip, Mate!!!
Working on 2 Tecumseh carbs at the moment one has a leaking problem. I thought it was a leaking bowl drain “button”. Anxious to try this great tip. Thanks again!
Wow! Thanks again. Great video. Super helpful.
Excellent site - I have fixed multiple problems and troubles on my home power equipment - Thank You !
Not sure if I had a flooding issue, but after I cleaned out the vent hole in the carb of my snowblower, I was able to run it with the choke off instead of full choke which was my main problem.
Sure glad I came across this video. Thank you 👍🏻
Thank you! I had a carb that no fuel would get to the bowl, so it was vapour locked I guess. I knew about that little hole but yours was the only video I could find telling me how to unclog it. The twist tie wire did the trick.
Happy New Year Don!
Good to know, thanks Don! 😉👍
Great stuff donyboy73. I follow you on ALL small engine repairs. One note,,,,Don't break off that drill bit in the vent hole.
Thank you very much! It is very useful to know.
Great video, what a trick! Are there any other engines besides Tecumseh Snow King 8HP and up, that have a similar vent that might get overlooked? (I have a 7hp tec on my blower, for instance, and a random assortment on other equipment.)
Wow did not know about the vent hole, good stuff Don
Nice. I’m bringing a snowblower back to life for a neighbor. Unused for at least eight years. On to the carb tomorrow. Good video. Thank you.
Thank you for your tip - needed it now!!
Good info donnyboy73. will go out and check to see if my Tecumseh has a vent hole 👍
Way to go Don Quick Tips
Very nice, thank you! I just got an old nice snowblower, 4 HP flathead, runs great but the carb drips gas, ill be going to work on it tomm, thank you much! 😀👍
If been fixing these for years and it always baffled me why an rebuild carb sometimes just does not work. This is the failure i have been missing. Thanks for the very helpful video.
very helpful video ! thanks for sharing !
Wow, what a great tip! I wonder if it applies to Honda carburators... Such a small hole is going to be mighty difficult to find!!!
Merci Don très bon vidéo et très bien expliqué , excellente qualité d'image je crois que tu as pris une de tes nouvelles caméra
Wow, thanks Donny, that hole sure is super small and easily missed!
Good one! Torch tip files work good too.
Great tip Donny: I had a 4 wheeler in my shop that the mud dobbers filled the vent hole and made it flood and fill the crankcase with gas. Thanks for the video's.
always great Dony, thanks ...
Very good tip! Thanks
great tip as always
Thanks for another great video
This is great - very helpful! Thanks~!
Hello Donny - Good Video - I have cleaned the same carburetor vent hole using my oxygen / acetylene torch tip cleaner - just to give you another idea - have a great day .
My Kohler engine floods all the time so I put a shut off valve before the carb. It never leaked so I didn’t know what else to do. Been running it like that for 2 years now but I’ll check to see if mine has this problem. Thx!
Question to you Don: Do you or have you ever done a video on how to work on a Honda eu2000i or the newer eu2200i generators?
Like why rough idle or surging? Just wondering! You are the best one out there in my book Don Second to None!!!
Keep up the great work👍🏻
Great tip. I never knew that vent hole was there. thanks.
Great video.have learned so much watching your videos. Would you happen to have a video on how the augers go back on. I have a 4h snowking snowblower and the snow is being pushed not being pulled into the auger main chute.
Thanks again
Awesome tutorial bro thank you.
thanks for the awesome information i had no clue about that !!!!
Simple Yes , but so important. Thanks
Donnie I have pulled a truck load of hair out with this 8hp Tecumseh. Did not know about this small hole that you covered in this video. Can’t wait to try this tomorrow.
Good video thanks
Thanks helped me a lot!
I just got back my anow blower from the repair shop for flooding issues. I cleaned card and replaced the needle and sear, but that didn't work. I've never heard of this vent hole. Great video, just a week too late.
Thanks Bud!
Hi. Thank you so much for this video.
On a Briggs & Stratton snowblower engine, is there an equivalent hole? I checked mine but just couldn't find any...
Great tip... I have a smaller craftsman that starts and runs fine for about 10 mins and then dies this looks like it could do the trick.
thanks that mat be a solution or a problem I have can't always use everything but there is that one gold ticket
After checking and setting the float and replacing the needle and seat I was at a loss as to what to look at next. Then, I found your video and was encouraged but on inspecting my carburetor it didn't look like it had such a vent. Finally, I decided to poke around a little and a slightly darker spot less than a millimeter in diameter caught my eye. Sure enough. My probe stuck! I'd say that vent is just a half millimeter in diameter. Fixed. Without a manual, can't imagine how I would have come up with that. On automotive carburetors like Carter AFBs and Rochester Quadrajets, bowl vents are enormous and you never think of them as possibly being blocked. For those curious, if the vent is blocked fuel in the float bowl can't rise. The air above the fuel is a trapped bubble. If the fuel level doesn't rise, neither does the float and the flow of fuel through the needle and seat continues. The fuel level does however rise in the main fuel nozzle, that tube running from the bottom of the float bowl up, into the throttle bore. donyboy73, thank you very much.
Hello Donny, writing from New England USA. I have a 1998 Snowking with Tecsumeh carb. It was leaking gas, I replaced it. It seemed fine but now it's spilling gas again from above the float and behind the carb. I'm at a loss. Thanks.
Wow.. been working on these engines for years and never knew about that vent! I had a smaller Ariens snowblower with a 3.5HP engine and the diaphragm bottom carburetor, and I even went so far as to replace the carburetor with a brand new one and it STILL leaked fuel and flooded out. I gave up on it and sent it to the scrap heap. it wasn't a junker either, it was well taken care of but I scrapped it because of that stupid carburetor.
Tecumseh was only good when they were making their stuff out of cast iron. Thanks for the input, I appreciate the information. Im sure these tecumsehs are either a win-lose type deal when they come into the shop
thank you
Hi Don.. I have a little 5 hp craftsman with a Tecumseh engine on it. Is that vent hole on the smaller units like that.. I see where you were with that hole and mine doesn't seem to have one.
Cheers for this tip Don. 😉 but can you tell me ...? If you push the dirt/blockage into the carb. Will it possibly block an internal jet etc? Or not.cheers Rob from England.
Hi Don . I have a tecumseh engine on an ariens 2 stroke snowblower that has a tiny tube sticking out just above the bowl onthe carb. gas drips out of it. I have cleaned many carbs of all makes and I have no idea what this little port/tube is for. Its very hard to get at the carb on theses so I havent taken it back off yet . any ideas?
THis is amazing. I just did a search today, i turn my fuel valve on The fuel was jsut puouring out of ym carb onto the ground.I never knew about this vent hold. ITs an 8hp as well on a simplicity sno awa 8. had running issues all last season.
Do you happen to know the size of the twist drill that you used in this video?
Thanks for continuously publishing great and informative videos. I have found myself searching your past videos to learn how to do things.
Best wishes to you and your family in 2019.
I think around .013"
Great idea. I use the cleaning wires that are made to clean my torch. Works great. But I think I'll use my micro drill bit in the future. Thanks!
MIG welding wire works quite well. I had this problem with a Tecumseh powered chipper. Like you stated, I did the carb several times before I found and cured the problem.
😊
Salut Don, merci pour l'information ! J'aurais aimé voir le comportement d'une souffleuse en marche avec ce trou bouché et ensuite débouché. Parfois nous serions en mesure de réparer un petit problème sans tout démonter. Bonne journée mon ami !!!
I’ve got a small Nikki carburetor from an Onan generator. Do you have a a source for the various sized ‘freeze plug caps’ (not sure if this is proper designation)? Mine are silver colored caps.
Thanks Don I will check it out the next time I have it in the shop ehhh
Thank you Thank you
I never knew about that hole .i learned something today
Will this be the same for a Briggs and Stratton?
Nice
That would be easy to miss. I wonder if a plugged hole would cause a vapor lock, or some issue with fuel siphoning between chambers. The mysterious complexity of carburetors is bewildering.
Thks Donny, learned so much from your channel. I have a couple of adjustable Tecumseh Carbs that didnt have Welch plugs in it when I opened them and dont appear to ever have one fitted, is this normal as I'm not sure of the exact purpose of the large plug inside the main bowl. Grateful for any advice
yes some carbs have a hole for welsh plug but don't have one installed
@@donyboy73many this for the reply
I have to agree with Grampie,............ I will have to check my Honda as well............. this is why “ WE” the general public turn to the “ TopGun”!!!!👀😏😎👌👍👏👋🍻✌️🍁
I would never have seen it.
