Over the years, I've made quite a few videos on how to clean a carburetor.
I've even done a video explaining how a carburetor works: • How does a Carburetor ...
Today, I'll be showing you how a Primer Bulb works!

Expected a video explaining the primer bulb function only. Learned so much more than that. I like how you showed what the clog can do with the barrel opened. This is exactly what I'm experiencing and I couldn't picture why it'd only run when primed. Thanks!
You have answered the type of small engine problems I have been experiencing for years! Thanks for posting!!!!!!!!!!
WELL DONE! Direct and to the point! You covered all the details with logical explanations. Excellent presentation!
This is the BEST description and help for not only the primer but also fuel intake. THANKS!!
Great video! Thank you. You do a great job of explaining exactly how this works.I like how you enunciate; very clear.
Dude how do you know we needed this thank you so much for all the details-man you are definitely family now to us,keep up the good work 👍 😀
Thanks for watching!
Your enunciation was great, easy to follow along. Thank you!
Another great video by EP. THANK YOU FOR ALL YOUR VIDEOS .. GREAT JOB . EASY TO UNDERSTAND. LOOKING FORWARD TO THE NEXT ONE.
Thanks for watching!
I really like and appreciate the amount of information you give into it really helpful👌👌
Such a great vid. Straight forward and to the point. Thank you!
Good explanation and the video to go with it clearly showed what you were discussing. I particularly liked when you centered the feature being pointed out. This is probably quicker than going back in to edit-in an arrow pointing to it, or a circle around it, but just as effective.
Thanks for watching!
Awesome Video. Its guys like you that make CZcams GREAT!! If I can make one small suggestion. For some viewers they might have a problem figuring out what you were pointing to. A small pick or awl touching the parts would be helpful. I don't need it myself but others might. Thank you for taking the time to teach us !!!
Excellent tutorial. Well Done Sir.
Great video!!! I am retired and started a small engine repair shop and I watch your videos because I need all the help I can get. Never to late to learn....
Thanks for watching!
So glad I found your channel. Excellent work!
Thanks for watching!
Nice job with the presentation!!
Thanks again for an excellent explanation. Keep up the great work!

Thank you for explaining how it works. I appreciate it. 👍
Thanks for watching!
Very well explained. Thank you.
Thanks for watching
Awesome sauce thanks man.
Great video step by step guide this how we learn to do it right thanks. 👍
Thanks for watching!
great job ! thank you !
Super helpful video! I learned a lot. Used to put premium in my snow blower as it contained NO ethanal. All fuel in Canada now sadly contains 10% ethanal which is unfortunate for small engines.
Esso 91 contains no ethanol where I live!
@@EliminatorPerformance It did here too until recently. Our Federal Government quietly implemented that change. Many still don't know about it. This also won't be great in the spring when the classic cars begin to hit the roads.
Great vid as always!! Thanks!!!
Thanks for watching!
Thanks for the info
Best video ever
Thanks for the explanation. Maybe next time I may have trouble with a small engine carburetor, I mat figure it out.
Superb!
VERY GOOD
Great video ., I sold a lawn mower on march 13 . With snow and ice still on the lawn . I have never sold one this early before .
Nice, thanks for watching!
Great job I learned a lot from my video
Wery well explained by doing.
Thanks for watching!
Thank you for posting this! Very good info. When I tried starting my blower the first time this season, it was below zero and the primer bulb wouldn't press. something seermed to cause resistance. Once it was warmer out, I tried it again. no trouble pressing the bulb in but this time I could hear air each time I pressed the bulb and it wasn't moving any fuel at all in the carb. Sounded like just air moving and there was really no resistance with the bulb at all, which I would expect if it was moving fuel. Any idea what could cause this? My first thought was maybe a split somewhere in the line but by the sound, it seems to be moving air and the sound seems to come from the carb. Thanks again for the info!
Thank you for this great explanation. Can you tel me why i have leaking gas trough my primer bulb primer? Thank you again.
Thanks
my problem on the cub cadet snow blower carburetor is the upper fuel bowl gasket leaks causing it not to prime. Is there a better gasket than the cheap factory type gasket. A part number would be good too. The main jet and tube are clear. Thank you..Pete
Thanks for the video. I have an engine similar to this (briggs and stratton XR 13.5) on a Chinese excavator but it doesn't have a primer bulb. do you know of a good way to get fuel to the carburetor on a gravity fed system after it runs out of gas?
I have a 2 stroke Toro snowblower and when I press the prime bulb no fuel is getting to the carb but I can hear the air bubble in the fuel tank. Whats going on in this case? If I manually put some fuel in the carb it will run and stay running.
Thanks.
Great information. Sub/Likie!
Very informative. I just got an older B&S snowblower engine. model 252413-0727-01-87063010 .The primer bulb was stiff so I decided to remove it. However the plastic housing of the primer which is made of plastic cracked so I have to replace the whole assembly. Interesting though is that there are 2 lines going into the primer bulb. I don't know if someone played around with it some time ago or is it an original primer bulb. One line seems to lead directly to the intake pipe and one goes to the carb. Can I just replace the primer bulb with only 1 line that goes to the carb?
Thank u
Got a new primer bulb and carburetor but can't get the rod hooked up the spring should be easy I have a toro 518 zr power clear if you can show me how to get it connected
Nice to see you removed the choke plate and shaft from the carb so your viewers would have a good look at the distribution tube area the primed fuel comes out of. Good job buddy.
Thanks for watching!
Thank-you
Thanks for watching!
Hi . my problem is it’s priming through the normal distribution tube in the centre. but also coming out of one of the front jets at the same time. any help would be greatly appreciated. thank you
I know now, thanks.
And the hits just keep coming!!!! Great video. Question: what if your primer bulb doesn't push back out stays collapsed on your Tecumseh King engine 9 hp. Thanks.
Clogged up carburetor, most of them have a relief hole now though
@@EliminatorPerformance I will check. Thank you.
Great video! Could you do one on the primer bulb of a two stroke?
Yes I can, spring is coming so maybe that'll be a chainsaw or trimmer video!
I didn't know that . I thought it pumped fuel through the hose like on a 2 stroke. Thanks.
My snowblower only runs with the choke on. when I turn the choke off, it slowly peters out and shuts off. Any idea?
Hmmm I had it backwards. I thought the primer created a suction which drew more fuel into the bowl and up through an inlet port on the side of the throat.
Great explanation as always Jake.
Thanks for watching!
I have a Toro CCR 2450 two stroke. If I push the primer bulb 2 times it floods the engine and won’t start. Instead of using the primer bulb, If I just put the choke on full and pull the starter rope 4 times it starts. Why does it flood when using the primer bulb? I am reluctant to use the primer bulb because I don’t want to hassle with a flooded engine when It’s time to move the snow. Any suggestions?
Hi bro, a great admirer of yours from Toronto. I have a Brigg and Stratton snow blower that has exactly the same carburetor. The problem you discussed in this video, I’m having the same with mine. I press the primer button and start it with electricity because it doesn’t start manually. It stays on as long as I keep pressing the primer but when I remove my hand, the engine turns off. I removed the carburetor cleaned it very well and made sure it’s not clogged, put a new spark plug but it still won’t start. Please suggest something that I’m missing. Thank you
You might want to make sure fuel is flowing from the fuel tank, as well as through the carb. Remove the bowl on the carb while it's on the Snow blower and turn on your fuel, make sure fuel is coming out. Will be a mess but sometimes they clog at the line or sometimes there's a small screen in the fuel inlet. Search donyboy hidden screen in carb.
Good day Boy interesting video. Is that why they are putting primer on chain saws now too. I think myself motor with primer seems to start quicker . Thanks good video
Right on Don hope your doing well from the OLD
MAN
Make a bubble carb it's like they should have always been there it's perfect it act as it's own filter like a water bong and you can even use bad gas because it just uses the vapors it doesn't use the liquid as long as it got vapors it's good maybe add a heater to make more vapors but it works good on a 150cc scooter
thanks.....
Hey my craftsman only starts when I push the electric start button but I can pull the rope all day and nothing the bulb seems to be pushing air what now.
I would also stress the importance of a good sealing gasket for the bowl. If the bowl gasket isn’t making a good seal not only will it leak gas but the primer wont be able to pressurize the fuel in the bowl to force it through the Venturi.
Any chance you could explain to me why zero gas goes into my carburetor? I can only assume my gas line is clogged. I pulled the bowl off and pressed the primer.... Nothing at all
Great explanation.
One thing that I would like to know is why does the primer bulb have a small hole in the center of the red part. When you press on the primer bulb, your finger is loosely covering the hole.
That's to let the air back in when you release your finger, so it doesn't suck fuel up the line! Thanks for watching!
What would cause the primer bulb to piss out gas ? And the carb leaking all over , I thought maybe a line rotted
👍👍
Will a Toro snow blower start if the out side prime button has a crack it briefly starts but shuts down
If you have to keep priming it, it's most likely the main jet that's partially clogged and needs to be cleaned.
I need a new carburetor I damage it so will that correct the main jet clog??
I have fuel that's bleeding back through my primer hose and pouring out is there something wrong with my carburetor
Leaking Needle valve and probably a clogged main jet?
Hey Eliminator, like your vids..
I have an 11hp Tecumseh blower , new carb but the engine cuts out after 30 or so secs.
Could it be electrical ?
Thanks bud.
Take the fuel cap off and see if it keeps running, sometimes they don't vent properly
Thanks Eliminator, I think it worked seems to run now ,, a simple fix.
Cheers
What would cause the fuel to come out from the primer button constantly but no start from the snow blower? Even when off and the fuel button is left on the fuel is just pouring out, what would cause that?.
Probably a leaking needle valve! The bowl is sealed, and if you're main jet is clogged and the needle valve leaks, the fuel would most likely leak out of the primer
Thank-you
I’m curious. You said that carb was from a B&S engine.
Are you aware of a carb of the same design that would fit my 9.5hp Craftsman snowblower that uses the stupid Nikki carb?
Blower model 20A114-0363-E1
Yes, many of the Nikki and walbro carbs are interchangeable, but you have to experiment with it because the jet size could be different
Just returned an aftermarket carb to Amazon because it wouldn't prime. Nikki style for a briggs 1350 snowblower.
I've had to do that too, Amhousejoy was the dealers name.
I always look for a primer. Had a auto choke on a mower that never would start without problems.
Thanks for watching!
Nice and informative video brother but you didn’t tell or show how to take out the distribution tube.
Watch this brother; czcams.com/video/uksV4JFsFc0/video.html
Thank you. Appreciate it!
Great explanation. You talk like a robot.
have you ever dealt with these new Murray push mowers leaking gas from the primer bulb? czcams.com/video/5AV2gn0YLUs/video.html he did push the primer bulb like 20 times before it leaked so maybe it's normal for it to leak if you over-prime it. but he still goes on to show the mower is a piece of shit right out of the box. Or maybe it's possible it's not a piece of shit. If you over prime it from the start, does the gas level in the carburetor return to normal while mowing or will the gas continue to flow and keep the carburetor overfilled and choke out the engine?
Everyone saying it works no it doesn’t
Duh I got a new machine let's put shitty fuel in it.
Thank you :)
