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.

When I rec'd my Ariens 920014 (10 years ago) and primed it for the first time. The gas did start to leak. Thought something was wrong, so it was sent back to the supplier to check it out. There was no charge and they said nothing was wrong. It was because I primed it two many times. Now I only prime 2x and never had that problem again. After 10 years the engine just started surging. I added a little sea foam to the gas and now it runs fine. Thanks Donyboy73 for what you share. I hope people appreciate all the time you take to help us.
Thanks. For 40 years I have been wondering why this sometimes happens. Have a great night my friend
You save my day, I was thinking there is either something wrong with the carburetor or a leaking fuel line. Thanks again, you are truly a pro!
Great to hear!
Everything I know about my blower came from watching your videos!!! Thanks again!
Thanks! My brand new snow blower had this problem last winter and I thought it was defective. Now, I know it was me who probably over primed the engine. I ready for winter now. Thanks again. 😀😀😀
Mine did this after I re-built the carb and I was worried I had either done something wrong or that there was something wrong with the carb itself. I think you just saved me the trouble of tearing this thing down again!
Makes me glad to hear this. Mine does it and I thought something was going to go wrong 😓
Thanks for the tip. Had my snowblower for years, first time I noticed anything spotting on the floor. Glad I don't have to worry.
Another great vid, Dony. What people don't realize or understand is that on a 2-stroke engine application...the primer bulb is just that. The bulb actually holds small quantity of fuel and moves fuel from the tank to the carb and back again in a continuous motion assuming the bulb itself and the lines are hooked up correctly and perfect condition. These large rubber bulbs mounted on the outside engine covers are what I call "puffer" bulbs. They do not hold any fuel nor do they move fuel. When pushed, they simply puff air into the float bowl chamber which forces fuel droplets into throat of carb and manifold. They do seem to work better and drip less if you fully close the choke first then pump the bulb.
Sir, following your video, I was able to troubleshoot my snow blower. I was a phone-call away from spending a fortune for doing something foolishly (over priming the unit). Thanks so much, sir.
Good one Dony. My daughter was worried when her snow-blower did this. I told her the primer mechanism was like a small squirt gun squirting gas directly into the carburetor air passage. Squirt to too many times and it will leak out.
exactly
Im so glad you made this video because my was leaking and i didnt know why. At first i thought a hose fell off or a cap i was looking hard and scared to use it thinking it would catch a fire. I picked it ip and put in the back of my car but to get it in i tilted it not realizing it would leak. You video showed that i wasnt missing anything on the torro thanx again
I was lucky to come across this video, this is exactly whats happening to my snow blower Poulan Pro w/ Tecumseh engine.
I was about to bring it in for service. I wonder what it would of cost me? I was over priming.
Perfect timing for this video. I just saw my snowblower do this yesterday and wondered if I was priming it too much. Thanks again for all your excellent videos.
Good to hear, I just replaced my primer hose that broke and then it started leaking when I primed it, thought it was another issue. Lol Thank man!
mine isnt priming correctly---gotta figure fuel line is bad,,gonna change
This was a very big help for me. The explanation of my leak was well explained. Appears someone had the same issue. Thank you again .
Thanks Don, this is a big help. I was going to call the dealer, then I remembered that it only leaked after it was primed. Great video.
T
Very helpful video. Answered my question. I was wondering why does fuel leak from the back of the carb only when priming 3-4 times.
Thanks, You just save me some time and money. Getting it ready for the winter and I noticed the leak. Changed the oil, cleaned and gapped the spark plug. Good to go. Thanks, Keep making those videos.
Awesome! Thanks! Sounds totally logical. I was approaching the "paniked" mode you spoke of (haha) and was planning on pulling my carb apart this weekend. Excellent.
Thank you! Thought it was messed up...turns out I'm over priming it!
Really good information. I was going to ask this question about my Toro 2 stroke snowblower, which starts to drip after just 3 pumps of the primer. I'll try 2 next time. Big fan of your channel. Thanks!
Wish I'd have watched this before I bought a carburetor kit and spent $50.00 for nothing. This is exactly what happens on my Husqvarna. Thank you for this video.
@George Granlund I have a husqvarna st227 unfortunately I just discovered a gas leak, while moving it roughly 200ft. Only notice it, the last 15ft or so. It was dripping out and covered the left hand side tire, pretty good. As I was 15ft from where I was placing the blower, I immediately shut it off, turned off the Fuel. I noticed drain screw to carb bowl was wet, as well as the bowl itself.
Any idea what the issue could be..?
Much appreciated in advance, and thank you for your time.
Thanks Dony! I just replaced a missing primer bulb on a snowblower that won't start (and hasn't run in about 10 years) I am going to pull the carb to clean it anyway but I was concerned when it leaked gas while priming.
Thanks Donny! I was wondering if I had something wrong.
Very informative as usual. Here in southern Ontario we haven't had enough snow for me to use my blower yet this season.
Amazing video, Thanks for sharing! Mine is dripping occasionally without even priming and just sitting, it’s fairly new and have used once or twice every season. Not sure how to fix that.
Great info, thanks Dony!
I have a problem similar to this very informative video. The tank was empty when I filled it with gas. I did not touch the primer before I noticed a small stream of gas shooting out of the rubber primer hole. Then, while checking the air in the tires, I noticed the gas leaking down from the carburetor in the same area as you noted. So, I had gas coming out of both the primer and the carb. It continued to leak and eventually stopped leaking down thru the deck. Does it matter if the fuel cut off switch is off? Thank you very much!!
Thanks a ton I just cleared the snow had same issue I was about to dig deeper now I don’t have to next time will be careful primping, God bless you🙏
beautiful. I'm saving this to my favorites and will share it with my customers when they don't believe me that over priming these tecumseh snow king engines will cause some gas leakage.
seems like a worldwide problem, lol
Hi dony keep making those videos you are amazing with what you do and you are extremely helpful!!!
thanks for watching
Very helpful.
I have fuel coming out of the tiny hole on my primer pump, any explanation of this issue?
Thanks.
did u figure out why this happened. mine is starting to do it.
Thank you I wished I watched this video first before changing primer hose
Thank you ! Mine ran well until i noticed the drip when priming we I never noticed before. Now the engine surges what causes that?
Love this video. God bless your heart for sharing this knowledge. You are truly one in a million and I appreciate the time you take to make all the videos packed with useful info
Cleared up my worries about my old craftsman 2 !!! Thanks Danny! Newfoundland!
My garage was smelling badly of gasoline. So this year I’m like maybe it’s the carb. I see gas under bowl screw wet. So I decided to replace carb . The new one came with no screw and spring under bowl. Which I was nervous I got the wrong carb? Still nervous? I assembled the new one onto blower. It works fine! But still smelling gas in garage? So I didn’t replace gas primer. But with your easy video I will. My rubber is fine. Garage kept blower in winter and shed in summer. All rubber lines are still soft with no dry rot!
Even though blower is 20 years old !
I’ve never had an issue starting it! I run carb gas out after each use and shutting gas valve off!
Is it ok without bowl screw not on it? Or did I get wrong carb??
Great video. Nice straightforward explanation. Much appreciate that. I subscribed.
Your videos are the best very helpful I enjoy them
*THANK YOU!* I've been worried, too, about the leaking. And, just as you explained, it seems to happen when I primed it, usually like five times! I hoping that it's just my over-priming! Mine's a two-stage Troy-Bilt, about ten years old, and it's seen light usage and seems in good shape, but has a leak exactly like you showed. *Thanks again, you've put my mind at ease!*

Thanks Dony. Love all your videos. I just fired up my Craftsman snowblower (B&S engine) for the season. Started up great but was slowing down then speeding up. I noticed that gas was dripping constantly from the carburetor. At the end of the video you mention that if this problem exists take it to a professional. Anything I can do myself? Would replacing the carburetor solve the issue? Thanks
these are good carbs th-cam.com/video/elsP-Sp62z4/w-d-xo.html
Hello Donyboy really like your videos,I have a problem with fuel leaking out of the primer bulb itself, what would cause this
This video is great and describes the exact problem I was noticing (Same Engine). I usually prime 2-3 times and have never noticed gas flowing back out from the intake side but after buying a new aftermarket carb online one prime seems to spew one pump worth of gas out the back side. Is there anything I can do to keep it inside the carb with one pump?
I had it leaking because I was pressing wrong and too many times and the engine wasn't firing up easily. If it leaks, it's because it's not pressed right. Now I press only once and keep it there for 1 second, then quickly release it. Engine fires up right away every time.
Thanks Don. I will make it work next time. Have a good one.
Thanks for all the awesome posts. ANY CLUE why when I prime the engine 1st time this yr it primed way too much fuel? It was like the primer system wasnt drawing any air with fuel just pushing pure fuel. Every push produced a stream of gas. I took the carb off , checked the float, needle, etc. put it back together and seems OK. I was thinking too much gas in bowl? THis is an Ariens 24" with an LCT engine. Engine has been pretty good for 5 seasons save for a couple carb issues.
Thank you Dony for sharing your vast wealth of knowledge of small engines with the general public. I envy Joel having had the opportunity to have you as his mentor. I'm sure the experience will serve him well in his future.
I have a question regarding my 10 hp Snow King snowblower. It has a feature where the auger lever will automatically lock on when it is released providing you have the throttle lever depressed. This is a great feature if you use the manual chute a lot. Alas, it will no longer lock on for me. I was hoping that you could point me in the right direction so that I could be a happy camper again. Cheers from the Maritimes. Thank you.
The one time my Tecumseh *didn't* leak fuel after priming, I took the carb apart convinced something was wrong. :D
Thanks for that. I didn,t think it was normal. Thanks again!
Wow. This video saved me a panic attack!!! Thanks!!!
I always wondered why that happens to my snowblower. Now I know. Thanks!
Ive had carbs leak on motorbikes but that was a dirty pin valve or the pin through the float pivot point was sticking, i only have a simple b&s mower and priming is a different style, so no problems :-)
Thanks for making this! I was wondering.
Super helpful. Thanks. Took some stress off me.
This happened to me today ( the fuel leaked when pressing the primer bulb). I might have pressed it too many times but it did finally start. I have another issue with this new snow blower. It only starts using the electric start when it’s cold. After it runs awhile and I shut it down, it will start with one pull. Any thoughts? Thanks for the video
Great videos Dony! Thanks for putting these together! I have a question for you too. I have an Ariens 927LE sno-blower that I bought new in 2009. It has the Tecumseh engine. I had used it a couple times already this winter and has worked great! However, when using it today, it starts just fine, but after several minutes, it just dies. As if it's not getting fuel. Even though they didn't look dirty, I cleaned both jet plugs in the carb and also checked my spark gap. Still does it. Any good ideas you may have I would really appreciate! Thanks Dony!! Keep up the great work!!
+Gear Hammer try replacing the gas cap, often they do not vent
Dony! That was it! Youre a genius! The rubber cone inside the cap had fallen out and I found it in my garage. I reinstalled it and it works like a champ! Thank you sir!!
+Gear Hammer you're welcome
Hi, just take the snowblower out first time for the season. At first I primed 6-10 times, then I saw gas leaks, just like your video. I lay it down on the side to check it out, then I lift it backup and waited until the next day. and now, even I primed 50 times, and I don't see any gasoline leak like the night before. Did I cause brake something?
I want to take the cover that goes over the carb, hoses, etc. but don't know how to remove the knob of the choke lever. The set up I have is exactly like the one you show in the later part of your presentation. The are a few screws to remove along with a hex nut but obviously the cover can't be removed unless the choke knob is off. Thanks
Shouldnt I feel the primer bulb full of fuel? Or is it normal for it to just sound like air shooting into the carb? I assumed its not getting gas because it wont start. I replaced my fuel line and checked for cracks in the primer line. Cleaned carb last night. Thought it was starving for gas?
I have a craftsman snowblower with a Tecumseh engine. Model 640349 and a 5002 carburetor. It was not running right and leaking bad.
I replaced with a new carburetor and it started right up and runs fine. The only problem is gas still leaks out of the mouth of the carb after I shut if off and it sits. I have to elevate the carburetor side of the snowblower with a 2X4 under the one tire to keep gas from dripping out of the carburetor intake where the choke is. I have watched and after I shut it off it takes about 30 seconds then it starts coming out of the inside and runs out of the choke hole / mouth.
Is this normal and I wonder why no one mentions this problem.
Thank you for your help.
Hello Dony,! My snowblower didn’t start and not knowing why only after one winter use. I figured out it was the gas and so I empty the tank and added a new one. In doing so I primed it more then enough times but I got it to start only to turn off seconds later. I noticed a gas leak and freaked out. Empty the gas tank again and let it dry. I filled it with gas, primed it only to have same issue. This time it didn’t start but I primed it again, yes, too many times. I haven’t tried again and wanted your suggestion. It leaked from the same area that you show on yours but how come it won’t start with new gas? I have a Troy built 2420 that I got for last Christmas. I need your help.. thank you for your time.
I was just noticed this the other day when I primed the engine... thanks
just went to start my craftsman lawnmower, self primer, for the first time this year and filled it with gas and when i pulled the cord i noticed gas pouring out of the carburator onto the deck and it would not stop. i had to take the gas out and check it. when i took the casing off to check, poured somemore gas in the tank and nothing was leaking , put everything back together and everything ran fine. question , donny what would cause this to happen?
Thank you again Don.I always thought my Father was just over priming it.My Dad says when he sees gas drip its ready to start.I was worried it might be issue,but you cleared that up.My small engine repair guy said we needed a whole new carburetor,I'm gonna share this to his timeline.Thanks Don,love your videos
Donyboy73, is this the 10hp engine?
I bought a a 10hp Tecumseh off Craigslist, is has a "516" on the Carb, I know it is not the the original carb (the previouse owner told be he bought the carb new (but it doesn't look like what you have on the one in this video), will the carb work for me?
I am going to use the engine for on a logsplitter.
BTW the engine starts, only when I spray engine starter into the carb. Runs 20 secs I am VERY new to adjusting Though this 516 is the non adjusting carb you talk about in other videos.
Also, the Tecumseh Control Bracket Assembly is on the side of the pull rope housing BUT there are no wires or cables.
Please advise, Mike
Hi Dony, gretings from Croatia! Your vids are just fun to watch and when you need it very helpfull. Keep up the good work, and bring us more vids!
I have an Ariens with a Tecumseh engine and I smell gas coming from the snowblower when it's parked in the garage (winter or summer), nothing drips or leaks. Is that common? It's stronger than I'd suspect if it were just temperature-related expansion or something similar.
Thank you. Saved my day.
Thanks -- Answered my question!
Hi Dony I had a question regarding an aftermarket carb I bought off Amazon. I installed it on my Toro single stage snowblower with the RTek engine and it fires right up but it does surge a bit. Am I supposed to adjust the carburetors when installing aftermarket ones? Also how long do I leave it choked when warming up when cold. I usually open the choke right away and the machine dies. Thanks
Thank you!!!! This was a concern of mine ! Your awesome ! Great vid! So helpful !
Thank you. Makes me feel better.
Thank you for that video, I think you just saved me a lot of money, now I think my snowblower doesn't start because of the spark plug, at least I know its normal it is leaking (I know nothing about engine obviously, I just know I don't have enough money to buy a new one).
Great Videos to learn by. My snowblower looks like the one you have in this video. When I press on the electric start, it does not turn over. It just clicks one time and then blows the garage fuse. Any suggestions?
try a different outlet, if it still happens replace starter
I always wondered about this. Although, I did have a leak on mine when I tilted the snowblower back. I found that the carb bowl gasket wasn't seated correctly and this was actually keeping the primer from working properly as well. Pulled the bowl off, smeared a little oil on the gasket and the bowl went into position nicely and got a good seal.
7 years later......I have this issue with my Murray snowblower. When I tilt it back, it leaks. Set it level, no leak. Can you explain the fix to me please? Much appreciated.
I have a power that doesn't work properly. There is no need for priming, but leaks gas even after changing the carburetor and pump. Any suggestions.
Hey Donboy! Great video as always. What's your opinion on the best brand for new 2 stage walk behinds?
+Pa Aa Honda, toro, ariens
+donyboy73 Thank you! I really enjoy your videos! Great job!!
My brand new Ariens Classic snowblower does this too, with the AX 208 engine
I have the same model. 1st time I used it last night the oil dipstick smelled like gasoline afterwards. Changed the oil this morning it had gasoline in there. again after use , dipstick smells like gasoline. I did prime it both times but I guess it’s a carb problem ?
Is it normal for fuel to leak out when you tilt the blower backwards out of the carburetor?
I have an MTD with a Tecumseh carb. There is a continual leak through the air bleed valve. Any ideas how to repair this condition? Thank you!
Wish I saw this video before I dropped off my SB at the shop earlier in the day
My craftsman snowblower with Briggs engine does not have fuel shutoff, should I install one? How?
My fuel line was leaking in my snowblower so I had to replace it. Holy cow was that a pain to replace. I got the same inside diameter, but the outside was just a tad wider. I had a hell of a time snaking the line between the engine from one side of the blower to the other.
Thank you for your video. It was very helpfull. I had the same issue.
Great to hear!
Yes I do as well get a little zealous with the primer bulb and gas on the ground. I have an issue with gas ackually blowing out the primer bolb hole.
Hello, I have a tecumseh 2 stroke motor that is not priming gas into carb, I cleaned carb really good, blow it with air, you think it may be still clogged?
Thank you, i nearly called a small engine repair. Im an idiot and over primed the engine LOL!!!
Hi Dony, I have a question on the NOCO GB30 you reviewed. Have you tried powering a small 12v compressor from it (either with an adaptor or directly from the clamps)? Will the booster pack send voltage or would the electronic protections kick in and cut the tension? Thanks.
Mine does this, but doesn’t start, what’s wrong? I thought the fuel line was needing to be replaced.
I have a single stage that's leaking by the gasket next go the engine. I can't seem to find the parts. It's a toro ccr 1000.
hey thanks for sending me this video helped me a lot. you do great work.
Thanks you saved me from a service 👍
Why would you need a primer in the first place since it has a manual choke? I thought that the primer systems were a replacement of the old chokes in older engines?
I have a mtd snow blower the engine looks the same. I don't believe my engine does that. It's probably 11 years old. like your videos.
My mtd snowblower does that and dies unless I keep pumping the primer in a slower rate the motor keeps running if I stop it dies. Is this a stuck needle float? Just bought it and it's a mtd Trac 26/8 snowblower and also the blower won't do anything with the drive levers. Any ideas on why it wont propel itself forward or backwards? Just a diy guy here need help
Awesome started up the snowblower for CT first 2020 noreaster and this happened..... Excellent explanation as I was like oh fuck with 22" on way. LOL I did prime it 5 times
thanx a million don , youve created an excellent channel \m/
What is the best 2 cycle oil to use in my Toro CRR Powerlite? I currently use Opti-2 but wonder what the professional recommends.
+ChicagoSirens OPTI-2 IS GOOD, I USE CASTROL OR STIHL OIL
+donyboy73 Is it safe to run it at the recommended 100:1? I always have the fear one of my engines will blow up.
Hey donny I have a 1964 home lite XL-12 chainsaw that has a stripped out spark plug hole. Can I just replace the cylinder or do I need to rebuild? Where are the best places to get parts besides eBay? Love the videos very informative and entertaining.
you could you a spark plug heli coil kit
