thanks alot steve you saved me alot of money mower works good as new easy fix thanks again michael from baltimore
In a pinch without micro drill bits, I used my torch tip cleaning files.
So gonna try that man thanks so much
I'm a "mature woman" lol & I followed your instructions completely. Worked like magic!!! Much thanks from Georgia!
the link for the micro drill bits is no longer valid, the description of the item is correct, but its not available for purchase, nor are the pictures correct.
I'm a single mom homeowner and I find this guy hilarious! No way I'm paying to have my mower fixed before I try myself. Great video.
That is awesome!
Oh Liz, I totally agree with you. I love this guys videos! And believe me, He knows what he's talking about.
Ahh, a kindred spirit. 👍
I do hope you enjoy a fine amber beverage also!
All well and good just keep in mind most places charge extra if the owner has already attempted to fix it because we then have to fix your problem plus the original problem. None the less have a go at it. It ain't the space shuttle after all lol
72 yr young man here and have flipped a lot of snow throwers, lawnmowers, garden rototillers over the past 40 yrs. Always nice to see someone like Steve who enjoys his work and explain things in detail. I’ll drink to that Steve. 🍺
Right on
I was able to clean the cartridge no problem! Now I have to change the oil and the spark plug. I learnt something new today! Thanks again
You're Welcome...
Same problem!! Brand new mower, with clean new gas, third mowing and this jet is clogged! Cleaned it and it worked for one more time then No Start!!! I’m now drilling out this damn jet! And adding a small filter in the fuel line!! Thanks dude!
You're Welcome...
Much respect. I own a small engine repair shop in South Carolina. What we do is starting to be a dying trade. Lot of machines are throw aways now a days. The only way I make money is by fixing stuff and not replacing parts. And the worst thing is a customer bringing something back. You take pride in what you do. That itself is a dying art. Donyboy, Taryl and yourself are awesome. I appreciate the time you put into your videos.
Thank You... Were you ever in the 9th Infantry?
No sir.
I’ve seen a ton of these Briggs coming through the shop. I tried drilling out the jet with an old micro drill bit set. Apparently I drilled it too big and it ran too rich. But, I agree, the jets in these things are way too small. Experience is a bunch of compounded mistakes.
Parts are getting out of site. I fix stuff on the side. You can’t charge by the hour you wont have a business long that way. Part time or hoppy or just having something to do can put a few bucks in your pocket. Am older and enjoy working on small stuff. Most dealers wont even touch a weed wacker cause they charge almost the price of a new one.
@@arthurrodesiler3109 And it will take them a week snd a half to fix it, snd you usually have to go by and check the progress. You then get the ole, "I was gonna call you..."
What makes Steve so good as a small mechanic Professional is his ability to test, Diagnose, Re test and check it again. He learns each time he makes a repair. And then what makes steve so great is he's generous with his knowledge and he teaches others. Absolutely fabulous job steve!!!👍👍👍 And have a beer for me.
WOW! Thank You...
worked great! repaired neighbor's mower
Nice job!
I must have cleaned the carburetor three or four times before finding this video. Drilling out the hole on the cartridge to a 20 thousandths of an inch finally fixed it. Thanks much!
Glad it helped
Thank you so much. After watching your videos, my husband and I had our old mower running like new in just a few minutes. We almost threw it away. Thanks again. We are older and on a fixed income, every little bit helps!
You're Welcome...
Sweet! Drilling the main jet out with 0.5mm bit worked for me.
Thanks for instructional video on this!
Great to hear!
Followed your videos regarding this carb to the letter! Problem solved! So, very much appreciated!
Right on
Thanks @StevesSmallEngineSaloon! It started and died after a few seconds. Checked everything I could think of. Saw this video on that plastic carb and now it's working like a champ!
Right on
Couple of points. When removing white cartridge, be very careful if you use small flat blade screwdriver that you insert it deep enough between side of white cartridge and black sidewall so you do not damage the thin O ring at the top of the white cartridge. When reinstalling this cartridge, be aware there is a plastic sleeve that sits in the body of the carburetor between the butterfly valves. It has a hole in the side wall of the sleeve. You cannot see this hole unless you remove the sleeve. This hole in the sleeve lines up with a hole in the body of the carburetor. The central jet of the white cartridge must pass through both of these holes to seat properly. Sleeve can shift while you are working on carb making it impossible to reinstall white cartridge. Cartridge should install with little pressure to seat it properly. If you find it very difficult to reinstall, sleeve probably moved and holes not aligned. To fix this, need to gently remove the larger butterfly valve (throttle) metal piece. It fits into a slot in the small plastic pin the holds it in place. GENTLY spread the slot apart and GENTLY remove this metal piece. You can then pull the pin out giving you access the the White/Grey sleeve. Can use your small finger to reach into space to sleeve. Use small probe and insert it through the hole where the main central jet on the plastic cartridge seats in the carburetor while using your small finger on the sleeve to align the holes. Once aligned, remove your probe but keep your small finger on the sleeve so the holes stay aligned and reinsert the plastic cartridge. Should easily seat in place. Reinstall throttle pin and gently insert the metal piece into the slot in the throttle pin, making sure you have it oriented properly. What should have been a 20 to 30 minute job today took almost 2 hours because of these issues (torn O ring) and trying to figure it out ( as well as breaking that plastic throttle pin and having to glue and clamp it and waiting for it to cure before being able to reinstall it)
I think he heard you. He did another video just to mention this plastic sleeve! Well done!
Do you have a video on this procedure please..
Yikes, I need to read this comment again in future before I attempt any maintenance on this carburetor though, reading this has scared me so much I may never try it now! I would very much appreciate a video that allows me to visualize what you have described here. :)

Many thanks for your important complementary comment.
That man is a 'ginormous' talent. Respect due!
Thank You...
@@StevesSmallEngineSaloon hey Steve I need you help I bought a new carbureoter for my mower cause I cleaned it and that didn't fix it so I bought a new one and it still won't run it is not getting fuel to the motor I don't know why ?🤔
Thank you. My wife was trying to do something nice for me and filled the gas tank. Unfortunately it was a can of my old oil from oil changes. I am preparing to clean the tank and carb so I can mow again. I assured her I am not mad at her.
Steve, a simple observation:
I use small engines A LOT when mining in Alaska. THE worst source for water and "stuff" that clogs jets is the gas can. "Stuff" just appears in them and no one notices until the jets get jammed shut. A good, micro screen filtering funnel helps A LOT on water and junk. You checked out Mr. Funnel products a while ago and I use them 100% of the time because "Time is Money", especially WAY back in the Pucker Brush.
Another "trick" from long ago is to KEEP the fuel tanks full when storing for a short time. The water that gets into the fuel (especially Gasahol in the lower 48) comes from the outside venting / air exchange of the fuel tanks. With a lot of air in the tank there is a lot of expansion / contraction of that air and the water vapor is drawn in with that exchange air. A full tank at the end of the day or before short storage means very little air exchange and almost no condensation water.
Long term storage means draining the tank, running the engine until it stops and then final draining of the tiny bit of fuel in the carb bowl. Open Ended, Really, Really long term storage means a little 2 stroke oil in the cylinder to help with rust and at a later start-up.
I just stumbled on my first Briggs plastic carb yesterday.
All I Can Say is they sure are strange. Thank You, for helping, Steve.
P.S. - No Gasahol in Alaska - it freezes in the winter. 😵💫

Hey stevens, this one really helped me. I've had that damn carb off 3 times, cleaning it. Put it back on, it would run for 10,15 minutes, then stop. I was loosing it! Then I watched you man.. drilled that little shit out to 20 thou, wa,la, runs like the wind. Your awesome my man! I thank you, your saving the little guy a few bucks. I appreciate your help and your time. Thank you, God bless..
You're Welcome...
The fuel line should have an in-line filter because its inevitable that debris will get in the fuel, I seem to remember putting one in last time I had to clean the stupid carb out.
Sounds like Micheal has some slightly dirty fuel, defiantly a design flaw in these new carbs. Stevens is the MAN. this make me wanna start doing small engine repair. must be tone of these new carbs out there.
Thank you Steve! I've got a Troy-Bilt with a Briggs engine and the plastic carburetor. For a while I got by by removing the carburetor and merely sloshing it around in a can of gasoline. Then the frequency and character of the problems increased. Most recently I got the oscillating engine speed. That's a nightmare. I ordered a micro drill set from Amazon because I wanted a next day solution. I also order the set with the HSS drills. That left me with a smallest drill size of .6 mm but I decided to go with that because I didn't want to fool around with stainless steel drills. I followed all of your instructions after very carefully enlarging the main jet to .6 mm. It started on the first pull and ran smoothly. I could have never imagined such a simple solution... but it worked! Thanks again.
You're Welcome...
@@StevesSmallEngineSaloon I didn't see the set of drills you recommended until after I ordered another one. Oh well. Your recommendation there was better, too.
Thanks Steve! I just got home from picking up a brand new (last year) mower for $25 that is currently on Sale at Canadian Tire for $429.99, normally $499.99.
I put a couple of drops of fuel in the carburetor and it started up for a second.
I've been working on small engines for close to 50 years, and have no doubt I could have easily taken the carb off and cleaned it etc. and had it running.
I also consider myself smart, so came here looking to see if there were any tricks before doing the job. I did see your previous video about the choke getting stuck. I will look there first.
It is raining out right now, and my "shop" is my back yard. I wanted to thank you in advance, just in case I forget to thank you later.
Update: Had a break in the clouds. The choke was fine, so I had to take it apart. About 20 minutes worth of work and it runs perfectly. I changed the oil in this "just add oil" motor as well. Total cost: about $4.00. 3 and a half bucks worth of oil, and about 50 cents worth of carb cleaner.
Thanks again for the video!
Great video once again! Yes thats right! do your own work! I started doing my own work 14yrs ago and saved myself a TON OF MONEY, TIME, FUSTRATIONS, WEAR AND TEAR on my car./ and that means I have more time to Drink Beer at the end of the day, Thank you STEVE
My lawn mower wouldn't start today. I replaced the spark plug, air filter, put fresh gas in it and it still wouldn't start. I was going to bite the bullet and replace it but I decided to search youtube for a fix and came across your video. This video saved me from replacing my lawn mower. I appreciate what you do. Liked and subscribed.
Awesome!
I'd cleaned a few carbs, but, this last one was my first "plastic " one. Did not know how to start till I watched this. THANK YOU
Right on John!
I like that sentiment about “needing to know why”
I wish I would have seen this video before I went to war with mine needing to know wtf is going on. I eventually arrived at your procedure but in doing so the other brass jet/fitting (not the main) fell out when spraying cleaner through it in my gravel driveway. That lead to several minutes on my hands and knees staring at gravel looking for a tiny jet. Found it,reassembled and cleaned. It runs great now but it seems to be a twice a season thing with these carbs.
I replaced the main jet with a Genuine Briggs & Stratton. Part number 594060. It’s a 500E series engine on an older Murray push mower from Walmart. I also replaced the spark plug with a new genuine Champion, part number RC12YC.
The engine runs perfect now.
Thank you!!
I kept saying something was clogged and after watching this video, I disassembled the carb and pulled the cartridge out. I tried to spray carb cleaner and the jet was clogged. I used a torch tip file to open the jet and sprayed carb cleaner through the cartridge and it blew through the jet!!
Reassembled and she started right up!!
Thanks again!!
Great job!
Hi Steve...... throw away a carb?? No way! I'm right there with you. And thanks to THIS video, I fixed my Briggs 500E in less than five minutes. I've no idea WHAT is actually causing these brass jets to clog up, but the .020" drill bit I cleaned it out with SOLVED the problem. (I've also STOPPED using Ethanol-laced fuel in my yard equipment and use Ethanol-Free instead... figuring its the excessive varnish in the Ethanol that plugging the jet). THANKS AGAIN for your GREAT video Steve! :)
Nice work!
@@StevesSmallEngineSaloon AFTER I sent this, I went deeper into your other video on the Stihl Motomix and the contents of the fuel mixtures. Then I felt kinda bad I wrote about the ethanol... evidently, THAT's not the problem. But running the ethanol-free fuel seems to be a little better anyway. That $28 a gallon for the GOOD stuff is too steep for me. I go thru a lot of fuel (big yard and lotta tools).... for a savings of >$23 a gallon, I'll clean out the jets every now and then.
Exactly the information I needed to get my mower going again. Thanks!
Glad to help
My lawnmower would not start. It had standing gasoline in the bottom of the airbox. Google's best guess, float valve issue. I followed your instructions in this video. Took my carburetor apart. Cleaned it. Put it back together. Lawnmower started on the second pull. Repair cost, ZERO. Thank you very much. A very, very, good video.
Thank You...and You're Welcome...
Man I’ve been having problems with my mower for weeks I’ve watched numerous videos cleaned the carb. Replaced plug filter and oil. As soon as I drilled out the jet it roared to life like it was brand new first pull. Thank you to the moon sir I’ve watched your videos in the past to fix my old stihl weed eater I don’t know why I didn’t come straight to your channel to begin with 🙏 I appreciate you sir
Thank You...and You're Welcome...
Steven videos are so helpful thanks bro, 👍✅💯
I just fixed my mower ALL BY MYSELF!! Just now! I'm still greasy.
That thing cranking was the sweetest sound I ever heard!
I can't thank you enough. I just love your channel and WILL BE sharing!
Also, My brother's name is Steve. So I see your merch in his future!
That's AWESOME! Great job Andria....
Received a Troy Bilt Mower for free today that wouldn't start. I was a plastic carb virgin but followed your instructions and now it starts on the first pull and runs perfectly. The main jet did seem to be clogged and I blew it out with carb cleaner. You da man.
Thank You...
Had same problem fixed thanks to your video!found alot of debris in gas tank due to no gasket on gas cap.they actually sell them new with no gasket
Steve, This is the type of carburetor I have on a two year mower. I was able to clean it following your directions with carburetor cleaner and get the lawnmower running again on the first pull. Thank you! You may want to mention please wear safety goggles and gloves when using carburetor cleaner. Also, I had to review the video to make sure that I put the plastic cartridge back in the correct direction. The screws holding the air cleaner cover were interesting to line up again. Two different sizes slightly different, and another size for the plastic "bowl" cover.
The different sizes are indeed a pain! I am a 1/4 inch drive socket set aficianado so it wasn't a problem for me, but ... why did they use two different sizes?
Thank you so much for this video. I followed your directions and my brand new- only- worked- one- time Husky mower worked PERFECTLY. I'm a 62 year old lady and I did this myself. So that means ANYBODY can do this per your direction. Thanks again.
You're welcome!
Great instructions ! I followed your advise and details . Now the mower is working. I dropped that dang pin so it took me 5 minutes to find it.
2020 CRAFTSMAN 2800-PSI 2.3-GPM Cold Water Gas Pressure Washer with Briggs & Stratton. New purchase $289, worked perfect.
2021 Summer. Won't start. Paid local repair man $40. Was told to use non-ethanol gas to prevent carb issues. Worked perfect.
2022 Summer. Won't start. Pissed off and tried to sell on Clist for $100 and no takers.
2023 Summer. Cleaned carb jet w/cleaner and 14K gold acid. Works perfect.
Thank you so much for giving me the confidence to solve this issue. Can't wait for next carb clog.
You're Welcome...
Thank you, thank you. Out of the box this mower would not start. Had guys look at it and couldn't figure it out. Stumbled onto your very easy to follow tutorial and even hunted down the drill bits locally. After doing the repair myself, this 65 year-old grandma started the mower on the first pull. Been starting ever sense!
That is AWESOME Audrey! So happy to hear....
Had a starting problem and your two videos were terrific! Got carb off, cleaned, and back on for a one-pull start in under 40 minutes! Couldn't have done it without your video! Thanks!
Great job!
Same I bought a new mower off market place and fixed it in under a hour thanks to this video
I just cleaned one of these Friday and was thrilled to get it running, now I need to get it back and drill the jet out so it will continue running. Love these videos, really helpful for do it yourselfers! Thanks!
You're Welcome...
Thank you, this fixed the no start condition on my mower!
Thank you Steve. I had 2 Toro B110 lawnmowers (from Lowes) sitting outside for the last two years. Circa 2018, 2019. Both worked for about 2 months each and then refused to start. I used your repair method on both and now both running very well. Two pulls to start them. Indeed, it was that interior jet that was the issue. I used the twist tie and several squirts of carb cleaner. Now... I need to watch your string trimmer videos and repair the 3 I have that are inoperable. Toasting your health with an Obsidian Stout. Cheers my friend...
Right on Dan! Thank You...
Did you fix all 3?!
At 3:39 note that the needle is mounted in a channel on the float. Very important when reassembling the unit. Some folks may just drop the needle in the cavity, causing the float to disengage.
Thank you! I just replaced the fuel jet in mine and it still wouldn't stay running. Followed your advice and now it works like a charm.
You're Welcome...
Best fix it video I have seen in along time. Sitting here thinking I need to clean carburetor as lawn mower won't start. Only 3 years old. Makes perfect sense. Cheap shit, I would normally say, not made to last, but in this instance, not made to start.
Thanks.
You're Welcome...
I messed around with starting fluid and gas additives for a couple hours on the B&S engine on my power washer, then hit CZcams for the solution and this video absolutely nailed it. I pulled the carb apart and blasted some high pressure air through the cartridge. That cleared all the small jets and ports inside the cartridge, I put everything back together and it started on the first pull. Thanks for the how-to and quick fix. Much appreciated!
You're Welcome...
"I messed around with starting fluid and gas additives." That's what I did weeks ago when I noticed mine struggling. Then the next week it wouldn't start. This vid and the prior - fixed it. I'm wondering if the gas additive removed debris but then it got stuck in the tiny cartridge holes. Factory flaw, but glad for this vid to become aware.
Hey Steve,
My son brought home a mower that wouldn’t start, I noticed that it had one of those Walbro plastic carburetors. The jet was clogged with what looked like corrosion so I drilled it out with a.04mm drill bit. Blew out the ports with carb cleaner. This mower runs like new.
Thanks so much for your advice and tips. I watch your shoe often.
You're Welcome...
That little main jet clogged on my father-in-laws as well. I used one of my wife’s small sewing needles to clear it. I’ve since ordered an inexpensive torch tip cleaner for future use.
Nice video. Thank you.
Right on
I love your common sense approach!! Repair, not replace. I have a lawnmower with one of those carbs. It just stopped dead yesterday and won’t restart, but will try with starter fluid. I figured it was water in the carb and checked out your video to see if I could drain the carb bowl with an allen wrench. From the glance of the inside of the bowl in this video, it looks like it’s designed to be drained with a quarter turn. If not, then you gave great info in this video to go further. I did small engine repair 23 years ago. But things change. And at my age now, I forget too. Good job Sir!!
Thank You...
Thank you!!! I watched a dozen other videos and disassembled and cleaned this carb. about 4 times. Watched your video and drilled out the jet. It started on the first crank.
Great job!
Thank you Steve for sharing your knowledge, I followed your instructions and was able to start the lawnmower in less that a full pull .
From Dallas TX
Excellent!
Steve Great video as always. You really explain everything well. I thought I would get out of this easy by dropping the float bowl and cleaning the one visible jet. It ran but there was still a blockage so I watched your video broke carb down, cleaned all openings and it runs great.
I use the ends of guitar strings to clean jets. They work great and come in all gauges. You throw them anyway when you restring a guitar. Thanks again. Gerry
This guy saved me 150 dollars to fix my carbuerator. Very detailed explanation.
Right on! Glad to hear it...
Competent and consice.
The man knows his craft.
Thank You...
I know I’m 3 years late to the party but I need to tell you thank you for this video. You saved me hundreds on a new mower. I was at my last straw. I cleaned my carb 3 times, the gas tank and fuel lines twice, new plug and air filter too! Could not get it to stay running. I mowed my entire lawn by spraying starter fluid at the intake the whole time! I never knew that little white jet housing could come out. Sure enough that “secondary” outlet was clogged. Sprayed it, used my pin vise to loosen the clog, sprayed it again and reinstalled. Now my mower starts on the first try (no ether) and runs like a champ! Thanks again, Sir!!!
Right on Brady! You're Welcome...
OMG, thank you! I bought a 7.25 Craftsman mower off of craigslist for $25. It was in great shape, but advertised as being unable to start. I first changed the plug, but that wasn't the fix. I googled "Briggs and Stratton carburetor issues" and found this page. After watching I took off the carb, which had piss-yellow gas in the bowl, and cleaned it. I also blew carb cleaner through the jet--I didn't need to ream the jet. After reassembling, I checked the choke and it WAS sticking on the frame, so I bent out the carburetor frame as shown in the other video. Long story short: the $25 Craftsman mower runs like new. One more thing: I drank red wine while working on the mower, Steve. Was that okay? Thanks for the great video!
--Steve in Flagstaff, AZ
Great job!
I took out the carb and cleaned it out and I brought my dead mower back to life. I also bought the drill bits you recommend below but they came in after the operation. The lawn mower has never run "right", so I think when I get a motivated I'm going to take the carb back out and try drilling that hole as you suggest. But it starts WAY easier than it used to just by doing this. Thanks for the video!
You're Welcome...
Yep, totally nailed it. This fix can be done in 30 minutes. Thanks, Steve! Cheers!
Glad to help!
Steve thanks so much for an awesome video. I’m by no means a small engine repair guy but followed all your instructions to clean the Briggs & Stratton 725 Exi carburetor on a pressure washer. It literally startled me when it started on the first pull. Unreal and fulfilling experience. Thank you sir!!!
Great to hear!
Brilliant fix Steve. After dismantling the carb 3 times I was ready to throw my toys out of the pram. Watched your video then drilled that jet out to .020" and she's running sweet. Thanks man.
You're Welcome...
Watched about a half dozen other b&s carb cleaning how to videos and was having no success until I stumbled across yours. Great walkthrough (particularly for the jet and cartridge) and nice close camera shots. Got it started on first pull. Thanks for the great video!
You're Welcome...
John Sladewski same exact thing here...
@@StevesSmallEngineSaloon Thanks, got mine started 1st pull after sitting in the garage for the last year or so. Home Depot wouldn't take their Yard Machine back. Carb cleaner was the answer.
Well try the rest and then listen to the Best. Steve small engine saloon
Thank you so much for these videos. Im fairly mechanically inclined but this was my first time cleaning a carburetor. The shop wanted $80 to do this for me so i said screw it ill give it a try, found your videos, and got er done! Im gonna buy one of your shirts for teaching me. I appreciate it :)
You're Welcome...and Thank You...
I want to THANK YOU!! I did everything you said besides drill it bigger and it started right up on the 1st pull just like you said or would. THKS AGAIN!!!
Great job!
Thanks mate. I have this mower my neighbour through out and I just drilled out the main jet and away it went. Can’t wait for him to see me mowing my lawn with his old mower priceless.
[Original main jet opening may be too small from the manufacturer & may need to be increased in ID with a tiny screw bit to allow better fuel flow after cleaning everything with carb cleaner & blowing dry with compressed air.]
Hi Steve, I just found you for the first time today, have watched four of your videos, & am loving the way you explain things for those of us who have little to no experience with small engines... THANK YOU! I just get worried that there are sometimes not enough closeups of how things look before taking them apart to help me get them back together properly & get all the screws & parts back in the right places & positions! Hopefully, the more vids I watch, the less foreign everything will appear when I get started.
Also, thank you SO MUCH for not having any background music in your videos... concentrating on the details requires all my attention & vids that add music are torture for people with attentional struggles. God bless!
[9.19.2022]
Dude you have helped me so many ways from chainsaws to weed wackers and every time what you say works... lm a fan cause you da Man !!!
Thank You...
So give him a subscription! It's free! 👍
I just did this and it worked great! A couple of other bad things about this carb; No room to get a 1omm aeen wrench in there to drain it without removing the carb. Fuel hose is barely long enough to get a screen in there, and not long enough for a better, paper one. Also, I could not get carb cleaner to go through one of the small holes, but it runs well anyway. Maybe I missed this on the video.
I watched this after I fixed and cleaned my mower since my engine started kinda surging after the fix (I was just happy it started up) but I happened to clean my jet with a twist-tie like he did as well, I laughed pretty hard when he did the same thing, but it worked for me! Gonna grab me a beer now, well done guy, thanks for the lore behind the carb, super informative
Right on Buddy!
I installed a shutoff in the fuel line and turn it off and run the engine until it runs out of gas when I'm done mowing. It actually runs for four or five minutes on what's in the bowl. Between that and using stabilized non-ethanol fuel I don't expect problems in the future, but if I do, I now know how to fix it. Thanks, Steve, very clear tutorial!
I had the same issue with my customer.I finally had a carb I put on from a blown engine. I still have that carb I can fix now. Steve,your the best. Many Thanks
Thank You...and You're Welcome...
Hey Steve I can relate ‘‘em bare assed after third time with that woman’s mower. Just watched your two videos best way to fix Briggs carb problem and best way to clean a plastic Briggs carb. Could hardly wait till morning to pull carb off of my 5 yr old toro 7.25 b&s. Pulled new carb off for the 4th or 5th time (getting really good at it) I was sure this time was going to be the cure. My bread wire tie measured .016 and was loose in the jet, so I figured it had to be at least .20, which is what you opened yours up to. Put all back together hoping to start on 1st pull, or at least by the 3rd. No go, but here is the thing, choke is completely closed and if I even give it a whiff of starting fluid not a squirt by the closed choke, it starts with almost half a pull. Runs great no misses until I shut it off. Will even start back up. Which tells me it is still not getting fuel??? Still ‘‘em bare assed Bill
I had to clean my sister's mowers carb twice this summer. She finally bought a Honda. Wish I found this video sooner. I'll be drilling it out before selling it for her to spare the next owner.
Right on
Thank you for posting this video, I consider myself semi expert in carburetor removal and cleaning now but more than that thanks for saving me about 125 dollars to have my lawnmover "repaired." Best video i've seen on the subject now for some cold ones! LOL
Right on Isaac...
Thank you so much for your detailed tutorial. My 2 year old Lawn Mower would start but not stay running. After following your directions its running again. I found and removed the deposits on the "jet" opening of the cartridge and the "needle" under the float. Thanks so much for sharing your knowledge.
You're Welcome...
after a twelve pack of silver bullets i was able to fix that fornicate carb thanks stevo
Thanks Steve. The twist tie wire and carb cleaner did the trick.
Excellent!
Excellent video, I fix my Lawn mower in minutes. After your tutorial all look easy.
Thanks
Glad to help
This was awesome! I was able to fix my pressure washer based on this video. I do question Steve's choice in beer but that's another subject. Thanks!
Fair enough!
Thanks for the showing how to clean plastic carburetor and drill out the main jet
You're Welcome...
My mower was dying after getting hot, running about half way through my lawn, sometimes much less in the heat. I thought it was the choke initially, but watched your vid, cleaned the carb out and checked the linkage clearance but was still having the same problem. I ordered the bits you recommended and drilled my carbs jet out, cleaned again, replaced the old gas and managed to mow the whole back yard.
It might have been my gas, despite running non-ethanol and using fuel additives I couldn't recall the last time I filled my can so I probably should have started there. This was a very informative video, I learned some more about my 7 year old mower which now runs great again and I saved a few bucks in the process.
Thanks a ton!
Steve, thankx... this is truly the information only available from the seasoned journeyman mechanic’s personal experience with these machines. Your willingness to share this is invaluable to the novice tinkers like me. Buy yourself a beer and send me the bill.
Great to hear!
Thanks so much Steve,
My neighbor asked me last week if I knew anything about Briggs & Stratton engines. I told him I've had pretty good luck keeping the two Quantum Briggs motors going on the two mowers I have. My mowers are 20, and 25 years old, and they both came stock with the old 3.75 horse B&S engines. The older of the two was lent to another neighbor who was kind enough to bring it back, not only with a bent blade, but a bent crankshaft and of course the lower seal destroyed, rendering it unable to hold oil. :(
Another neighbor of mine was a scrapper, so I asked him if he had any old Briggs motors around that might have a crank shaft for me. He said he had one, but it was a 6HP quantum that didn't run. I asked what he wanted for it, and he said since it was scrap, just my old motor if I could get this one running.
The 6HP quantum had practically no compression, so I went to pull the head off, only to find that all 6 bolts were loose as a goose. I bought a new gasket, put it back together and it's been running solid for 10 years.
The second, the 20 year old mower I bought new to keep at a second property. It had the same 3.75HP motor as my original, but came with a plastic carburetor, which was tank mounted, and looked like my moriginal, however, it never ran right from day one. It was subject to constant stalling, even when my grass was never an inch overdue for cutting. My scrapper neighbor had another Quantum 6HP laying on the ground beneath the bed of his truck, so I asked him what he wanted. Again, he said it didn't run, so he was fine with an exchange.
That motor had a clogged jet, which is such an easy fix, since the jet is in the bowl retaining nut. That motor has been running solid for 5 years now.
I told my neighbor, if it's a Quantum on his mower that I could probably fix it, so he brought it over yesterday.
It wasn't a quantum. It was a brand new Craftsman that had a new style 6.75HP motor with the same plastic carburetor who went through in your video. He bought the mower new at the beginning of the season and was only able to use it to cut his lawn 3 times before it quit running. It would start right up with a shot of carb cleaner, then quit. I was hoping it was just a stuck float, however the bowl was full with clean fuel when I opened it up.
The main jet was visible, and I couldn't see debris in it, so I figured it was time to search CZcams...
I couldn't see how the jet assembly was retained in the carburetor until I stumbled on to your video. Thanks. :)
I popped it out, and it still looked clean, however, I couldn't see light through it while shining a bright light against the nylon on the revers side, nor could I blow air through it. I worked a sewing needle around in the hole for a bit, then I could see light shined against the nylon through the hole. I was able to blow air through, then get a shot of carb cleaner to pass through from the other brass inlet with the output port blocked.
I put his mower back together, and of course it started on the first pull and sounded like a brand new mower. Hmm... maybe it runs like a brand new mower because IT IS A BRAND NEW MOWER!!!
I don't get it Steve. Why are plastic carburetors such a problem?
I have a reasonable understanding of metallurgy, and I could see if it were an issue of dissimilar metals, I.E. if the jet were alluminum, pressed into a steel body. But that is not the case. Why should the jets on these plastic carburetors be so easily blocked?
Thanks again for the great video. Like I said, I couldn't tell for certain how the jet assembly was held in the bottom of the carburetor until you showed me.
Steve
P.S. Are you really the man of Stihl? :)
Steve, a week ago I made the statement that I had never once worked on a plastic carburetor and hope to continue never doing so. Lo and behold, I see a newer mower on the side of the road with a free sign taped to it. You know I grabbed it and set about getting it running again. You guessed it... equipped with a plastic B&S carb. Consequently I had to watch this video. Thanks buddy for the lesson.
You're Welcome...
Steve! Thank you so much for posting this video. Because of you I got to play the hero today. Plus, I got to learn a little bit and save some money along the way.
Awesome! You're Welcome...
I did this on a lawn mower that wouldn't start. Now it runs very well, and my wife couldn't be happier. Thanks, Steve, for keeping our love life alive!
Right on...
Hey mate greeting from Australia. I was pulling my hair out trying to get our mower with this carby running properly. I tried every internet search. Man I am so glad I found this video. Whilst I couldn't open up the jet size as the smallest bit I have is 1.0mm, I did at least put a small bit of steel through i.e. the wire tie as shown. Now she is back and running. Thanks a million!!!!!
Right on Mate...
Steve, thanks so much for the great video on cleaning my briggs and stratton plastic carb. I ordered a new one on Amazon that was due today and I came across your video. Went and spent $2 on a can of carb cleaner at O'Reilly's, took the carb off, cleaned it like you showed (I didn't have a wire bit to drill the fuel hole out) and BAM! It fired up the first time. The one that shows up today will be going back to Amazon. many thanks and enjoy the beer on me.
Great to hear!
Your a rockstar!! My Husqvarna 3100 power washer that uses the Briggs plastic carb wouldn't start. Cleaned the carb per your directions and it started 1st pull! Thanks for the great video.
Great job!
Thank you so much for your instructions and your encouragement. Fired up first time and every time, sweet.
Great job!
Top job Steve- I appreciate your persistence and clarity - absolutely solved a very frustrating problem for me. Had to get the glasses out to deal with those pesky little drills but it was worth it. Started first pull on re-assembly and hasn't missed a beat. Cheers and have another cold beer - You deserve it!
Excellent!
Thank you - You help save a Briggs & Stratton mower
You're Welcome...
Just repaired a Bolens with the Briggs plastic carb. I opened the jet to .020” and voila problem fixed. Thank you for you great tutorials.
Glad it helped
Thank You!! I have one of these carbs and it’s been driving me nuts. Never would have figured this out for myself so really appreciate the video.
You are so welcome!
Just had this exact problem. Smallest jet ever 😝
Thanks Steve, you’re one of the best!
You're Welcome...
Always a great teacher!
Thank you! 😃
Thank you couldn’t figure out if that jet cartridge could be removed. It was all clogged. Appreciate the vid!!!
No problem 👍
Thanks Steve... and cheers!! Pulled the carburetor and cleaned it following your instructions. Started on the first pull. Great videos!
Great to hear!
Great video! managed to fix lawnmower quickly and always love to learn a new skill.
great attitude to repairing and not replacing parts unnecessarily, we need more of this! cheers!
Thanks 👍
All I did was blow out all the jets with my compressor. Runs like a champ now! Loved this tutorial. Next time I tear it apart I’ll be sure to drill the jet out.
I cleaned my carb. following your directions. The main jet was clogged. It started on the first pull. Thank you!
Great job!
