High lawn mower lady, I am hoping you can help me. I am looking for what carburetor to buy for a Briggs and Stratton 190CC indeed CC professional professional series 600 Briggs and Stratton is no help And all my searching on the Internet does not does not help me find the correct carburetor to purchase. This is actually for a brute22" trimmer. The model number is BS1022H. Are you able to help me find the correct carburetor to purchase? Thank you very much

I'm a 64 year old woman. Bought the lawn mower last year worked great won't start. Took a few things apart cleaned them. Then I had to come to your KZbin video for help. I watched a few others but yours was more thorough and explained every part. I think taking off the top is a much better route than some of the others showed. Think that's my next weekend project. The weeds are overtaking my yard.

I watched half a dozen of these videos on this carburetor cleaning, and this one was a stand out. She walks you through the relatively easy (once she shows how) method to remove the linkages from the unit (I messed it up the first time I tried doing the clean). Further she did another breakdown of the nylon stack which no other video showed and all I can say after doing this, was able to finally get my lawnmower to run. Don't waste your time on the other videos; start and end with this one. Nicely done "Lawnmower Lady"!

I would like to take a moment to thank you so much for your how to step by step video. It was Christmas Eve 2022 and our lawn mower began losing power and stalling on sloping surfaces ran fine on even ground. I disambled the carbureator and found it full of water also found the breather hose not connected to the air filter. After performing all the steps in this video our lawn mower is back up and running and no longer losing power or stalling when mowing on a gradient/slope. Your video has saved us time, money and a whole of stress as we were about to give up and send mower for repair. Thanks agin so much!!!!!!

Very nice work! Clear and concise. The only thing I would have done differently is drained the tank and started with fresh fuel, since there was so much water in the carb previously and you were not sure where it came from. I definite learned a couple of things from this video! Liked and subbed!

[@TheLawnmowerLady]

Thank you Mr. Eric for the sub and the suggestion. I did indeed drain the tank, but I figured the video was getting a little long.

[@eljefeslash]

Thank you, Lawnmower Lady! Every year, it's the same thing - my lawnmower won't start, so I pull out the carburetor, clean it out, then it starts right up. This year, I repeated the process, but it wouldn't start. I was scratching my head and after enough wasted time, I pretty much decided I was going to go buy a battery-powered lawnmower after work, that is, until your video popped up in my feed. I saw the problem at 8:00, the white donut ring had popped out of my carburetor when I had removed it from the lawnmower. I had no idea it had gone missing (and didn't even know to look for it as everything looked ok inside there once I popped the fuel stack back in). I went back out to the garage and found it camouflaged with lots of junk on the floor, put it back in, and the lawnmower started right up! Thank you for your detailed instructions, just enough info to get right to it and point out all of the important parts, but not too much like some others can do. I especially appreciate that you showed how to pull the carb off of the lawnmower (I had figured that out on my own previously, but it helps to see the whole process - and...pulling off the cover is super simple and makes removing the carb easier) - other folks just start their videos after they've pulled the carb out. Looks like the ole' gas-powered lawnmower will survive another summer.

[@TheLawnmowerLady]

Thanks! Your comments are music to my ears. I'm so glad I could help. Some of those have a black donut ring collar,, and those are nearly impossible to find in the dark recesses of the garage. Cheers!

[@andersforrad]

Great video as always! Engines with the plastic carb has a tendency to surge due to the small jet. According to Briggs they run very lean due to emission regulations in different states. They surge a lot here in Europe too. A tip here for all if your carb is clean and it still surges - is to upgrade to a bigger jet - Briggs part no 596524. That often fixes the problem. Personally I prefer to old carbs where you could adjust the mixture. :) Cheers!

[@TheLawnmowerLady]

Great tip Mr. Anders! Thanks again for watching :)

[@randy1ization]

just think abt this for a minute.. briggs uses the same exact carb , with same exact jets, throat size, ect for 4.5. 5. 5. 5 , 5.75 hp mowers... how are they achieving this wide difference in hp, with the same carb? I dont think they are., I think its a scam. most of the new generation has never used a real 5 hp engine so they dont realize the difference.. they jets are way too small to pass enough fuel for the hp they claim., also the throat of the carb is restricted by a plastic ring .. why did they do this? I think its to restrict air. the engine operates under vacuum, and can only pull so much fuel out of the jets under a specific vacuum and volume. another problem with the plastic carb design is the 90 degree bend in the white jet chamber. anytime a fluid or vapor has to make a 90 degree turn, it causes resistance by a factor of 5. example.. if you put a 90 degree fitting in a garden hose, it is equal to 5 extra feet of hose that the water has to travel thru.. its amazing that these mowers run at All.

[@nginmumbetse7894]

Interesting & thanks for the part number. Mine's what I call 'hunting' quite badly.. think that's the same thing as 'surging'.. Might give the different jet a go if cleaning the plug doesn't help. EDIT nice one - you set me on the right path to getting it sorted, using the old original jet (totally blocked, but once cleaned, turned out to be way bigger than the jet that came with the replacement carb I ordered off Ebay)

[@jackwarren3882]

If jets are not available, you can use a .020" pin vise or drill bit, whatever you like to call it & drill the jet out. I have had a 100% success rate so far.

[@jbw9999]

@@jackwarren3882 A video by Steve's Small Engine Saloon also mentions drilling out the jet to prevent it from clogging again. I noticed the "High Speed Steel Micro Drill Bit Set, 30 Piece" for $3 from Harbor Frieght has a bit this size. It's .5mm (same as .020"). But I'm wondering instead if just installing a fuel filter will also prevent it?

[@douglasphillips24]

Replaced the entire filter box & primer assembly & it started up ran for about 30 sec & cut off. Definitely thankful for your disassembly vid of this carb cause I suspect water is trapped in carb preventing fuel from reaching combustion chamber. Great vid. Thanks a bunch.

[@rustychrome]

Water contamination is the number 1 culprit I see that plagues all small engines. The ethanol fuel draws in moisture. Every mower I service, I completely drain all fuel from the tank and carb and leave it out in the sun or dry it bone dry with paper towels. Some models require taking things apart to get out any trapped water. Just a few drops of water can act like a check valve and prevent the gas from getting picked up.

[@gman2602]

Thank you soooo much!! I doubted that this would be my issue because I maintain my power equipment the best I can but I guess I still have a lot to learn.

Great vid, enjoyed it. Wasn't sure I'd reassembled mine in the right order but it seems I have. Mower starts fine now but can't stop it hunting.. governor's back and forth constantly and revs up and down at a rate of about once a second. Thought I had the o-rings in the wrong order on the intake pipe but your vid confirms I've got them right. got fresh fuel in the tank, the fuel feed pipe's clear, and the carb body is a new one. Air filter's clean. There's no variable throttle control as such on mine, there's just a spring and a rod on the governor that goes straight to the throttle butterfly, think it's designed just to start and run at one rpm setting (basic rotary mower with no traction drive). I never took the intake pipe off the block though so I didn't change the red o-ring (there was a new one in with the new carb, I'd wondered where that was supposed to go!). Magneto gap seems ok & there's a good spark, but I've not cleaned or gapped the plug yet. Engine's a 300 (doesn't say 300E, just 300). After reading Anders tip below I found a slew of different jets mentioned on Ebay - 596521,596522,596523,596524 - does anyone have a reference as to what size each is & which engines each jet goes best with? And, can you tell what size the jet module you have just by looking at it?

[@TheLawnmowerLady]

Sorry you are having trouble. If I read your comments right, it seems you have a replacement carburetor, and tried to clean it? If so, I would try to clean the original and put that back on. I know non-OEM carbs can be problematical. Your symptoms sound like the idle circuit may be clogged. Others drill out the main jet. I have done neither. The different fuel jet stacks are designed for different altitudes. You need a smaller jet size for higher altitudes to keep the engine from running too rich. As to which is which, I can't really help there. If you have a set of micro drill bits, you can size the orifice by which drill bit slides in easily. I wish I could be more helpful. I appreciate you watching.

[@nginmumbetse7894]

@@TheLawnmowerLady Thanks.. yes replacement carb off Ebay. I've never met an all-plastic carb before. Used to work as a lawnmower service tech here in UK but that was a quarter century ago. I tried cleaning the original carb but wasn't sure how to get the jet out; I figured it was non-removable and a new carb was only £10 or so. So I'm now wondering if the new carb I got, has the wrong size jet in it. Now I know how to safely remove the jet module I'll try removing & cleaning the one in the original carb. Should have googled you up right from the start!

@@nginmumbetse7894 I suspect your replacement carb is a victim of poor tooling. Some tiny passage is not completely bored out or something. Best of luck to you.

[@nginmumbetse7894]

@@TheLawnmowerLady Went back to the start & followed your guidance to clean up the old carb. Noticed the jet module in the old carb, once I finally had it out, was blocked in both the copper jets. Cleaned them out & once I could get an idea of their true size, realised the jet pack supplied with the new carb had holes WAY smaller. I put the cleaned, old jet pack into the new carb body, reassembled.. mower now runs great. Although the new carb I ordered was listed for a 300 engine (amongst others), I guess the supplied jet was just too small. I discovered the jet module is in two parts - there's an inner and an outer part to it and they come apart. Sometimes when you pull out the jet module, only the inner comes out and leaves the outer bits stuck down the hole. With the inner and outer parts of the jet module seperated, you can get at the air emulsion holes on the inner bit, and clean them out.

The Briggs 450e benefits from opening the carb jet to 20 thousandths - a stripped bread wire tie can be used to check that the jet is clear and big enough. Doing this helps the motor run better and cuts down on the need for carb cleanings. 👍

[@TheLawnmowerLady]

I know a lot of people do drill them out.

[@geredo1701]

Excellent video, you went step by step on each rubber gasket. Thank you very much. 🥰🥰🥰

This is a good video showing some details about the tier 4 jetting and the prime and start Briggs. My buddy gave me a 2015 ready start version of the 550EX that uses paper element, but can probably be converted to foam by removing one linkage. Thanks!

I appreciate you watching. cheers!

[@andrew4403]

It would be nice to hear it running after you were done fixing it. Other than that you did one heck of a good job of explaining how to clean that carburetor. Keep up the good work and I'll keep watching. Thank you and God bless.

[@TheLawnmowerLady]

I appreciate that. I thought that video was getting on the long side, and chose to edit that. Many other viewers said the same thing. Most all my newer vids include start ups. Thanks for watching. Cheers!

Hot Damn Thank You Ma'am 😁 I really appreciate how you showed the process, from start to finish.

Hello, great video. I've been doing small engine repair for about 5 years now, for a little extra cash and therapeutic reasons (some thing about fixing this little engines). 95% of the time I can get them working just fine by cleaning the carb just as you described, but on a rare occasion after fully cleaning the carb it will still not work properly. I've discovered that the ones that won't work have something in common, looking at the carb body from below (10:45), the hole on the right on a good working carb, blows out the hole at the front intake left inner hole looking at it right side up front view(can actually see the routing on the outside of the carb) the itomizer covers seals that hole with an oring. The ones that just refuse to work right, do not have this holes connected, my thought was that it's obstructed but I'm not so sure anymore. It's driven me crazy trying to find out what actually goes bad with these carbs, I've ordered re pop new ones when this happens, taken them apart a lo and behold the holes mentioned are connected. I disected one to see the obstruction but it seemed that it was built that way, so it got me wondering what I'm missing. They are anywhere from $9-$30 online so its not worth spending too much time on the issue, but it bugs me to have 10 of these laying around that just won't work after a thorough cleaning. I've fixed hundreds of lawn mowers, pressure washers, edgers and anything using this Briggs engine with the plastic carb. You got any idea what happens with this plastic carbs when a cleaning won't get them working right?

[@TheLawnmowerLady]

If I follow you correctly, that is a block off port on carbs that have a choke mechanism. They are really so cheap , easy to replace the entire thing if a good cleaning won't fix it. Thanks for watching. Cheers!

[@trimbletsc5]

THANK YOU SO MUCH LAWNMOWER LADY!!! What is that little white tube coming out of the carburator? The one just above the fuel tube? Every time I Push the air box it squirts fuel Thanks again

[@TheLawnmowerLady]

Sounds like an overflow port. Maybe a problem with the needle and seat? Perhaps something clogging the priming circuit? When you press the bulb, a few drops of fuel should be injected directly into the carburetor venturi.

[@TheRustyRooster]

Awsome job there, I look forward to more of your videos

[@TheLawnmowerLady]

More to come!

[@marvin-dv9in]

Great video. I do these alot. One thing I do that I didn't see you do was check for water in the gas tank. I just always take the tank off and clean it out. Clean carb, clean tank. Just a thought for you. Thank you

Dobrý večer.Můžu teda říct,že paní je super.Vysvětleno v jednom videu.Sice se v usa asi posrali,když dělají takovej plastovej šmejdskej produkt a s plastem nejsem dobrej kamarád,když se mi láme v ruce.Jo starý poctivý karburátor s kovu je nenahraditelný i když šasy mají trvanlivost 12-15 roků,tak motor vždy běžel.Dnes i to palivo s biosložkou stojí za hovno a zasírá to karbec a ani víkon motoru není jako u čistě rafinovaného.Je jaro a zrovna mám problém se sekačkou.Chytne na drb,ale hned zhasné.Karburátor jsem čistil,ale podle videa špatně a budu muset znovu dle videa.Před paní klobouk dolů.Je hezké,když vidím takovéto videa od lidí,co tomu né jen rozumí,ale jsou ochotni se se skušenostma i podělit o jejich znalost.Paní přeji jen to nejlepší a mnoho zdraví.Jirka

Bad gas and water seem to be the problem with a lot of the mowers I run across. I have also found that if you clean the spark plug with a hand powered wire brush then starting fluid and compressed air you almost never need a new spark plug.

[@TheLawnmowerLady]

I'd say bad gas is +90% of all my repairs.

[@kimwhitacre7622]

An awesome video! Your walk through is the easiest to follow. I have a briggs & stratton im trying to fix. Got the carb cleaned thanks to this video but when it was brought to me there was a piece laying on the deck. It's a white curved arm with a hole in one end that must connect to the choke to open and close it. Can you please tell me where it goes. Can't find a diagram for this mower online. Thanks

[@tmittelstaed]

One thing you should tell people is before tearing into the carb tip the mower on it's side take off the air filter and pour some gas into the assembly then try starting the mower. If the mower starts right up it's the carb. If not it could be spark, etc.

[@TheLawnmowerLady]

Actually I demonstrate that in several videos. I use a squirt can with 2-stroke mixed fuel. No need to turn over the mower. Thanks for watching.
