Just wanted to say thank you! I rebuilt my 4 screw Nikki carb that's on my B&S 19.5hp Opposed twin in April 2018, and it ran fine for about 5-6 cuts before the surging started slowly coming back again, only once blade load was removed, wouldn't idle worth a darn. I've tinkered with it off/on ever since, then just happened to see your video Sun morning. Went out to the garage & did basically as you described in your video. To my surprise, 3 hrs later of cutting the field, I was able to disengage blades 4x & put mower to idle to clear grass from the deck, and no surging!!! I thank you again for taking the time to post. Cheers!!
Just to update, I've performed this little carb "clean-up" procedure 3-4x since originally posting, as mower did have a slight surging episode once... no issues. This seems to happen more in the hottest summer months cutting when grass is really dry, I have Gator Blades on my rider, which makes mincemeat of the grass. So I think the engine sucks more grass particles in @ this time of year. Again TY for the tip!!
Buffalo Blue yeah they mower is gonna surge in the hot months u less u have the best gas online for your specific engine and good luck getting lucky to find a gas your small gas engines love I found a certain gas station I use locally to Fill up all 5 of my 5 gal gas tanks every morning and my small 2 gallon mix gas tanks for my lawn care business and I can tell a difference in how they run if my guys have to get the gas while out on a job sounds crazy but I ain’t kiddong
A little air bleed cleaning like you did helps fix a rich hunting idle and mid speed running condition like you had. Mine was doing this the other day and I did the same thing before seeing this. Now that the grass is cut I'm just gonna do a complete rebuild along with putting everything in the ultrasonic so it will get me through next season with no headaches.
My twin opposed Briggs was doing the same thing. I replaced the carburetor and it ran good for a while, then, started surging once again. Still have not found to cause. Will keep looking till I find it. Thanks for posting.
Awesome! I've been taking mine apart cleaning it every time. And what kind of camera do you have? Jesus, when spraying the carb cleaner it was trying to focus on your very close fingers. Almost enough to see who your ancestors were 🤣
My Murry, same setup you have is doing the same thing and separated the top of the carb so I could clean it even more. Ran the same jet wire you used and it's still surging. I will try it again. It's been a good mower and this is the only issue it's got. But thanks for the video
If I remember right the main jet is accessible through a bolt plug on the side of the bowl, you take the top off and that plug and a screwdriver through that hole to get that jet out to clean it. Try that, I think I did a video on that, it should be in my small engine video playlist.
Dude! ya got me to cringe with them screws at the open Carb. (-: yeah, today my '87 B&S same carb setup needed more choke time, and was surging. Btw you don't need to pull that lower air filter box to access that hole....that's when I made myself cringe. Putting them wingnuts back on the bolts so not to lose, over open carb. Be just like me to fumble such and nut falls in carb...teaching neighborhood kids some new words. (-:
oh yeah, thanks. Not a carb person at all. I did spray that hole but not much changed. At least from comments saying it's something for idle gives hope before farther, as idle is mostly my problem now. Two days back it even started at idle/no choke.
x2 on the thank you Gordon, and your fans. A debt of gratitude sending over y'alls gunwale. ~ I'm not one to poke an orifice with a paper clip but I sprayed the idle thang hole a buncha with carb cleaner I happened to have. Even back down that other hole north. Blasted it with pinpoint air fitting off the compressor every which way I could.. and popped a beer...blew excess carb cleaner 'n gas off(looked like a fire Haz), said a prayer and BAM! My '87 B&S/Simplicity was running at far bottom idle again. Woot! again, Thanks everyone! ~~ 1987 Simp/B&S 5212.5Hydro takin' names again. (-:
When my Briggs twin does that, I just unscrew the needle valve adjustment screw all the way out and while it's running I take an air nozzle with a tapered end, stick it in the hole where I unscrewed the adjustment screw and blow it out while it's running. Works every time. No more loping.
I don't have this kind of problem for my own personal and the one's I work on , I use 93 octane ethanol free with fuel stabilizer and seafoam in all small engines . Been using this concept for probably 6 years now , for I was told if I did it would cut down on Carburetor problems in the future . And it has .....
What was in the spray can that you used to clean that hole and what was the purpose of holding your finger over the hole for a while. Thanks and great video.
I got a tractor with this motor that runs when I feed it fuel with a spray bottle but I can’t get the carb to run the engine itself for the life of me. I’ve cleaned it as much as possible with all the jets and pathways clear and still got nothing. What’s the most important parts to make this carb run??? Maybe I’m missing something???
are you sure it is filling with gas? maybe you have a fuel pump or vacuum leak issue. I think I did a video on cleaning this carb at another time, look in my playlists for one called small engine repair or something like that. I know I did several carb cleaning videos. Good luck!
I have a lot of small engine machines and don't always get all of them treated before winter. Every year I have to clean a few carburetors of my own and a few for other people. Makes for good videos. Thanks for watching.
Gordon Robertson DIY I’m just now going to Clean my carb looking at other people’s inputs and different ways u suggest I use a tank w sea foam in it if so how much sea foam
gordo, thanks for the video, but you used a spray, and some kind of piece of wire, and then some copper thing, on the hole, could you please list exactly what those things were or links to what they are?
LOL. thanks. Can you tell I'm a noobie? Actually, your video was perfect. I was able to follow your instructions and my machine is working perfectly now. thank you so much.
I have this engine and need to remove the old carb and replace it. No videos on UA-cam about this particular model. Can't find any identifying numbers on the engine....do you know what carb to get? I'd love to see a video on removing and replacing this carb.
Sorry I don't have time to do a video on that. Usually there is a sticker under the seat on a lawnmower that will tell you what model and serial number you have, you can go to partstree.com or a number of other small engine parts sources and look up your part number and order from them there or cheat them and take that part number and put it in the search on amazon and probably get it for a lot less money.
i bought a long throttle cable and dedicated choke cable from Amazon because I put one of these opposed twins on a 2013-ish Cub Cadet that needed a motor. The throttle cable I used is 48" long. Its a touch too long and you can cut it very carefully to shorten it but I didnt, I just pushed the loop behind the steering shaft under the dash. The choke cable is 37" long. It didnt need to be cut it was perfect for me. Amazon Item # for the throttle lever I used is B00D9TI6WI and the Amazon Item# for the choke lever/knob is B0948FJG88. I hope that helps you.
A lot of could be's on that, usually takes me about 5 minutes to narrow it down with a test light and an ohm meter. Safety shut down switches like (low oil, under seat, mower deck clutch, etc.) ignition switch, coil, spark plug wires, bad or dirty wiring, bad or broken ground etc. Let me know what you find.
Biggest piece of shit carb that has ever been built in the history of man. I have bought 2 brand new. One ran for about 10 minutes and died and never started again. Next brand new one ran for about a month. Started f n up and have yet to resolve. Looking to buy completely different mower with out this setup. FUCK BRIGGS AND STRATON.
Could be dirt from the fuel tank or the old fuel line could be deteriorating from the inside and contaminating the fuel. These usually run very well if maintained. Ive had quite a few machines come in after a new carb was installed, but the root problem was something else. Just sayin
6yrs later... Thanks, brother. You saved me a pile of grief. That worked for me. Cheers. Jim

I have the same problem, I'll try this first. Thank you for making this video!
Definitely gonna try this now... my 19hp opposed twin is doing the same thing
Awesome! I've been taking mine apart cleaning it every time.
And what kind of camera do you have? Jesus, when spraying the carb cleaner it was trying to focus on your very close fingers. Almost enough to see who your ancestors were 🤣
Cleaned the jets and now it works like new. Great idea
Ah! Welding torch tip cleaner, another item for my Harbor Freight list.
They should have that, if not go to a welding supply or Amazon.
Perfect video thank you sir.

I've heard that before. I put premium in my motorcycle on the last fill up before winter.
What was in the spray can that you used to clean that hole and what was the purpose of holding your finger over the hole for a while. Thanks and great video.
Carb cleaner and finger over whole to create vacuum
I got a tractor with this motor that runs when I feed it fuel with a spray bottle but I can’t get the carb to run the engine itself for the life of me. I’ve cleaned it as much as possible with all the jets and pathways clear and still got nothing. What’s the most important parts to make this carb run??? Maybe I’m missing something???

Great job, it fixed me up!
A can of sea foam in a gas can of fuel helps keep things from getting gummy
Thanks for sharing your videos
I have a lot of small engine machines and don't always get all of them treated before winter. Every year I have to clean a few carburetors of my own and a few for other people. Makes for good videos. Thanks for watching.

gordo, thanks for the video, but you used a spray, and some kind of piece of wire, and then some copper thing, on the hole, could you please list exactly what those things were or links to what they are?
The spray is ... Wait for it... Carb cleaner
The wire is a piece of wire that fits the hole. Then the other thing was an air nozzle
LOL. thanks. Can you tell I'm a noobie?

Is that a welding torch tip cleaner that you used?
Yes
Thank you bless you do much.
Nice one Gordon. Do you use the sprayer for fertilizer?
Yes, but mostly weed killer.
Gordon Robertson DIY Hopefully not Roundup.
Prodigal Son is roundup finished in USA?
your still a cool old cat
Jeff Hibbard invented the $1.98 tune up and you dont use it
Do you know how long that throttle cable is and the choke cable and where we get it from?
i bought a long throttle cable and dedicated choke cable from Amazon because I put one of these opposed twins on a 2013-ish Cub Cadet that needed a motor. The throttle cable I used is 48" long.

4 screw fuel pump...Rikki carburetor.
Gord have you ever worked on those Intek Briggs engines?
Probably not, I don't know that name.
Good tip
Thanks Eric.
V twin Briggs and Stratton has no fire can you help
