Briggs and Stratton Flo Jet Updraft Carburetor Rebuild

[@bjayscanlon]

Thanks a bunch. Years ago, all of us guys actually carried zippo lighters. Had spare flints and fluid. I remember that burning sensation in my pocket. Those were the days!

[@mccoulombe941]

You the man Zippo Longer is better. So they say. You are the serious rebuild man i go to After laughing my way through a chicken dinner with Taryl dacturn!

[@mimimimi7979]

Great video

[@steveballard396]

Thanks for this video. Convinced me to tackle an old Briggs & Stratton 8hp on an old Super Tomahawk wood chipper. Started first pull after rebuild! Float was all gummed up and didn’t move.

[@ZippoVarga]

That is awesome!

[@davidv4200]

Needed to learn how to set a float properly for a flojet 4 bolt carb. Also needed to fix a fuel leak at the emulsion tube/ needle valve. I have reseated it and am going to try tomorrow to see if I have any leaks. Excellent video thanks a bunch

[@ZippoVarga]

Glad it helped

[@mikethetractorguy9780]

You don't know how much I appreciate it Zippo! The video is great! Wealth of information shown here!

[@ZippoVarga]

More than happy to help out where ever I can Mike! Cheers! Zip~

[@AwesomeFuture777]

I need to amend this comment. I was able to push the tube down against that spot and it went into the hole. I then tightened it per your instructions. Thanks!

[@greenmule4634]

Good ole long one Zippo the best kind and good info also, thanks for showing, hate to bang up fingers and hands but it happens , see ya on the next one.

[@ZippoVarga]

Glad you stuck it out to the end Mule! Cheers buddy. Zip~

Always great videos zip. Thanks for all you do for us l...👍👍👍

[@Maximus43968]

Great video my friend. Lots of good stuff.

[@ZippoVarga]

I'm glad you enjoyed it Max! See you Sunday! Zip~

[@Jim-ie6uf]

If the emulsion tune on the Flo Jet leaks, put one of the little white Teflon washers used to stop leaks on pulsa primes, on the seating surface of the tube. I did, it works. Well done video

[@ZippoVarga]

Yep! Part number 391413! Thanks for sharing Jim! Zip~

[@jeremythiel2550]

Awesome video

[@ZippoVarga]

Thanks Jeremy, and glad you finally made it to the live stream! Cheers! Zip~

[@BrucesShop]

SWEET !!! What would we do without air. Thanks for the carb clean. I have only done a handfull (6???) of the updraft carbs Bigger tillers and pull type rotovators. Briggs of course. First time I almost bent the emulsion tube by not removing it before taking the carb apart. This one's gasket almost looks like the one on my 18 Briggs opposed twin. I learned the draining gas problem isn't the needle the hard way years ago.

[@ZippoVarga]

There is also a teflon washer you can install if you have a persistent leak that won't stop. It's Briggs part number 391413. Cheers my Friend! Sean~

[@straightpipec6099]

Great video Zippo

[@ZippoVarga]

Thanks Sir Pipe! Zip~

[@straightpipec6099]

What rebuild kit would you recommend? Thanks

[@ZippoVarga]

Depends on which version of the carburetor you have. 4 screw or 3. Both can be found all over the internet. 3 screw kit number is 291763 and 4 screw kit is 299720 Just Google "Briggs" then the number. Cheers Sir Pipe! Zip~

[@waynecherry5301]

always enjoy revising the carb rebuild videos. The carb on the 12HP in the "Princess" was rebuilt @ the local dealer. Lord knows if the tech really paid attention to the float when the upper body (original warped) was replaced. The carb is a 4-bolt w/ a manual choke lever.

[@ZippoVarga]

Thanks for popping in Grinchy! Zip~

[@boneyardgaragesmallenginer188]

Nice job!

[@ZippoVarga]

Thanks Bone! Zip~

[@robertbusack2100]

Great Zip Tip!!!! I just did A Deajaveu like You and had some gone thru mixed up too!! like to see Dr.Seuss say that 5 times fast! LOL!! Another saved carb brought back too life Did You run it thru the sonic machine? it looked very clean. good thorough start to finish I bet a lot of watchers will gain much out of this tutorial ..Theres going to be a bunch of as BOB ROSS said (HAPPY CARBS) thanks to ZIPPO!!! Take care,bob

[@williammilbourn9262]

Hey zippo it’s the cop again just wanted to add that gas is flowing out of the bottom of the carb

[@ZippoVarga]

Order this part number. #391413. The kit included roll pins and teflon washers. Go to this video, then to the pinned comment and click on the link for the Briggs Bulletin which explains how to go about using the Teflon washers included in the kit. Video: kzbin.info/www/bejne/rmbWYXuLiKZjapo

[@robertcornelisse8664]

Thank you so much for these video's and sharing your knowledge. I just bought a mtd 960 with front loader that has been abused through it's lifetime. It runs but not great. My question, should i put money in it and overhaul the briggs or should i repower with something like a predator engine?

[@mikehrdlicka8635]

On the 8hp floor jet carburetor. The replacement plastic float. How to adjust float height no metal tab.

[@ZippoVarga]

Unfortunately, they're not adjustable. You get what you get and hope for the best.

[@willyck948]

Um.... I happened across a very unusual flojet today.... It has no high speed adjustment screw and the low speed is a needle with a lock nut. Its a mixer and I have no idea how youd hook it up as theres 2 nipple for the fuel inlet🤯

[@jessealt5415]

Hey Zippo, Thanks for your many helpful videos. I know this is an old video and you're likely not checking comments, but just in case... I have a question. At 19:44 you mention that weeping around the gasket is normal. Why is that? Is it because you leave it a little loose so you don't strip out the threads? But yeah,...It's been my experience that weeping everywhere is normal with a Briggs updraft...including from the owner when he's trying to get it to stop leaking. They're a good carb once you accept the drips.

[@ZippoVarga]

There is a weep hole with a brass check ball for allowing for pressure equalization where I point it out. I've got a few videos on the Up Draft, but check the latest two for an important leaking carb fix at the root of the problem. Tighten the bowl screws down. The vent will do its job and after watching the recent videos, hopefully you will be able to remedy your leaking carb issue. If there is WAY too much fuel leaking from around the gasket, I would suspect a needle and float issue. They should not constantly leak. Cheers! Zip~

[@josephpuchel6497]

Does it matter how many holes main gasket has other than screw holes ? Some have two holes one each side of main center hole then some have additional smaller hole on one end of gasket. Excellent video

[@ZippoVarga]

As these carburetors evolved, minor changes were made. You want to match your old gasket with the new one for best results. Zip~

[@AwesomeFuture777]

I just rebuilt mine per this video. I have an issue however. I put the emulsion tube in and before going all the way in, it stops my throttle flap from turning. It wont go into a hole, it will only ride into that groove and up to the flap. Why wont it go into a hole as you say it does?

[@mtwolinks]

Agreed! another great tip, and now I need some more help, please. Newly rebuilt ( thanks to your help) B&S #302431 ( 13 HP Horiz shaft Biggs from 1973). It drives a Simplicity Baron 3414S that I lent to my neighbor ( young couple in need of a mower and few $ to spare). It was running fine, then backfired ( by his account) and now I cant keep running, although I have compression and spark. I noticed the welsh plug ( I think that's what is called) was missing from the end of the carb. So I rebuilt carb, and it leaked so I remembered seeing this video and I came back to it to fix leak. leak now fixed, jets adjusted, and same problem: I can get started but won't stay running. I'm vexed. Any suggestions?

[@marshamoore7014]

check the key on the flywheel, may have jumped time

[@williammilbourn9262]

Hey zippo got a bad 3 bolt carb Briggs and Stratton been watching your rebuild vids and figured out I totally screwed up I am trying to find out where to get rebuild kits but us cops can’t figure that out it’s on a 70’s Montgomery Ward rototiller

[@ZippoVarga]

Rebuild kit number is 291763. Simply Google Briggs and that number and you will get numerous results. Some kits have a newer number, but sellers should reference the older number I've given. Forewarning, there will be extra parts. That's Normal! Use only what you take off the old carburetor. Good Luck! And Thanks for all you do! Zip~

[@not2fast4u2c]

You may have the answer to my question ..The emulsion tube from my new Briggs 16 hp carb has 4 spots for holes right below where the tube seats ..only 2 holes are drilled you showed that your's has at least 1 drilled .Is this really important since you showed it is for fuel draining back ?

[@ZippoVarga]

Heya Buddy. Did you buy one of those cheap Chinesium replacement carbs or an OEM Briggs carb? Zip~

[@not2fast4u2c]

@@ZippoVarga It is a cheap one from amazon It worked but leaked ..When I started having engine problems I put the old one back on ..I have since cleaned and put the old one back on the engine and it runs great I would like to get the cheapy one done right so I can have a spare carb

[@ZippoVarga]

@@not2fast4u2c The problem there is....there is no good way to remedy the numerous issues those carburetors have. But you can try using the Teflon washers that a service bulletin that was issued covers. It's part number #391413 and is intended for a different carburetor, so a kit comes with roll pins that you won't need. Here's the service bulletin to help our also: kzbin.info?stzid=Ugyz5a7G_sjjvcdYQul4AaABAg&q=http%3A%2F%2Fgoo.gl%2FVwyFqo&event=comments&redir_token=m-a4yTsLLjB-ebOLQsLDXOt1QqV8MTU5MTAxOTIwNEAxNTkwOTMyODA0

[@not2fast4u2c]

@@ZippoVarga I was going to try the lapping compound...So does it matter that only 2 of the holes are drilled when it has 4 spots on the tube.... If you want to see it..I posted a video last night showing the tube

[@ZippoVarga]

@@not2fast4u2c I'll check it out, but as for the holes, I wouldn't be concerned with changing the design. Zip~

[@robertbusack2100]

OH, I forgot the carb cupboard looks like an old factory medicine/eye wash kit do You have a bandaide in there for the fan finger? hehe i just couldnt let it go catch ya later

[@ZippoVarga]

lol, I had one in my camera bag, but forgot about it until I got back in the house. Cheers my Friend! Zip~

[@lkanavaros9576]

Never E V E R push the float against the needle to adjust float level! Good way to ruin stuff.

[@derekcollins1972]

Great vid. A new subscriber here. I'm working on the same carb here. When I was ready to take my emulsion tube out I noticed the screwdriver slot was all buggared. Is there any way I can get it out and have it still useable? I am thinking of drilling it out and use an easy out if there isn't any other way. If I do,would you be willing to sell me a rebuild kit for it? Thank you. It's going on an old 1971 8 h.p Briggs garden tractor.

[@ZippoVarga]

First off, thanks for Subscribing. Second, your rebuild kit is #291763. Just Google it and you'll find plenty of kits out there. Be very careful extracting the old Emulsion Tube out. The threads on the carburetor are a 5/16-32 and it's a specialty tap that's near impossible to find. Zip~

[@derekcollins1972]

@@ZippoVarga Thank you for the heads up on the tap. I'll try my best to get it out before I order the kit. Also thanks for the #. I'm in Nova Scotia so you have watchers far and wide

[@TheJulesbb]

Hey zippo”!!! On the 5/16s by 32 tap , can I just buy that tap at a hardware store if they have that size, or is it even different from theirs???? And “ on drilling out the emolsion tube, or nozzle, you say drill till I have 1/8 of an inch, is that diameter or depth??” I totally messed mine up”

[@ZippoVarga]

You cannot find them at a hardware Jules. They are found on line. Do a Google search for the specific tap size and you should get some results. Cheers! Zip~

Dam man never learn nothing Lololo be careful ok Thank You for information and advice

[@stevengrima2620]

Hi Zippo, thanks for the awesome videos. I have seen all your videos and have taken all your advice but unfortunately I am still having problems with my Briggs carburettor leaking and flooding. I have taken your advice on the emulsion tube but the carburettor still leaks. The carburettor is an after market carburettor and the needle seems to be a bit to sloppy and is no way as tight as the one you have shown in the video. Should I undertake a vacuum test to make sure it is seating or is your blow test sufficient. Thanks

[@stevengrima2620]

I also plan on undertaking a bench test tomorrow Thanks

[@ZippoVarga]

This is the same story I always get unfortunately Steven. There is no short cut or cheaper carburetor fix than OEM. The China knock off you purchased is, unfortunately, junk. You need to either rebuild the original, source a good used Briggs carb or purchase new. Sorry to be the bearer of bad news. Zip~

[@stevengrima2620]

ZippoVarga Thanks mate unfortunately i am in Australia and it is really hard to get a genuine carburettor

[@stevengrima2620]

I do have an original carburettor that has been rebuilt but unfortunately it has been rebuilt using aftermarket parts, will this be worth while or is it better off trying to get genuine parts Thanks

[@truckerdude4813]

Cant get seat out on my carb any tips?? Cant get good grip with screwdriver

[@nekotherion7317]

Would you happen to have any of these kits in stock? Im in kokomo and could use a few

[@ZippoVarga]

Kits are still easily found. The 4 screw kit # is 299720 and 3 screw carb # is 291763. Simply search "Briggs + desired number" and you can order what you need. Zip~

[@frankdeegan8974]

Zippo just get a finger full of old dirty grease from an old engine sitting around wipe that on the injured finger and forget about it in about 4 days you will be good as new. I do mine like that for 40 years or more. lol

Zippo!! I just rebuilt my 66’ landlord 101 carb (4 bolt) and it’s leaking like a sum bitch. It’s filling up the entire carb with fuel way more than the drip hole can handle. Do you think it’s the main jet tube or the float??

[@ZippoVarga]

Sounds like the float and needle aren't seating properly Pointz. Zip~

[@mischiefminded]

@@ZippoVarga Great vid and I also have a 8hp B&S troybuilt tiller with carb issues. Thanks for another vid on how to cure the leaky seep hole issue. Noticed while I was cleaning, the needle (after cleaned along with the seat) was looking like it was in bady shape. Do you know where I can get the needle replacement? Float is fine. Gaskets could use replacing as well. Thanks for any info.
