Ready to mow! Excellent demonstration of the task. Thanks Mick
No worries brother
As always good advice. 👍 My Qualcast Suffolk Punch mower had the same hunting/rough idle problem and has the brass bowl bolt jet, but I identified a slightly different fix that may also be worth checking before reaching for the finger drill. Mine has the through hole near the head of the brass bowl bolt as shown in the video, however when I examined the nut with my magnifying glass I found another absolutely tiny hole right near the very end of the threads. It was blocked. I gave it a poke with my smallest gas jet cleaner file (which only just went in) and it cleared the blockage and completely cured the hunting problem. This extra hole was so small I could barely see it without magnification.
Yes they do have a small hole at the top.. glad you sorted it
p
which engine was this?
@@benc2722 Tecumseh engine and Tecumseh Carb. I had to clean the holes out in the brass bowl bolt and the main jet this week as over the winter the fuel had slightly jellified and it has been cutting out on me. I paid special attention to the super small hole at the end of the brass bolt threads as well as the main through hole near the brass bolt head. I also gave the main jet a clean with the gas jet cleaner. All is now well again. 👍
Great tip - Thanks. The grass couldn’t wait for the fine drill bit set to arrive once ordered. So I went to the hardware store to buy a new bowl nut and seal. Surging is gone and the engine runs like a top. Appreciate the knowledge you are passing on with your channel.
Thanks mate happy mowing
I bought a set of jet cleaning wires off Amazon. I believe they are a less aggressive solution than these drill bits. I pulled the carb off, ran two different sized wires through the orifice, and BOOM...Fixed!!
Yeah I use them too.. I like the drill bits myself
Just to say thank you for this. Ive got a very new hawksmoor bell & stratton. Put it away for winter, got it out last week and was doing this. Simple clean of the carb and the fix in your video did the trick. Just to say thank you for sharing 😊
You are welcome mate ... Happy mowing
Well stone me it worked Mick! I followed your instructions exactly. I was a bit dubious about drilling out the hole at first but the orange drill worked perfectly and just needed a little persuasion. So pleased all is well. I won't relate my catastrophe with the fuel and float but that's another story and nothing to do with your solution. Thanks again!! 😀😀😀😀😀😀
Lol . So glad it worked out for ya mate. I'm pleased
Thanks Mick good tip for Fix. Mine also had a break in the sheath on the push pull cable to the safety handle you hold in at the grip. Bit of slack in the cable so the mower would not start sometimes or die suddenly as if you let go the safety handle.
I use a product on all my garden tools called FTC decarboniser. It's made by a company in Australia called Cost Effective maintanance. you just add a small amount of liquid to your fuel each tank and it will keep your fuel system as clean as new.
Interesting tip as usual Mick . Stay safe and healthy and your family ..
Thanks Rodger me old mate
😀 love a quantum 🍻
The double gasket trick worked a treat on the husqvarna
Thanks for this. Worked like a charm!
No worries
Great video, my briggs 190cc has not been smooth running since new, after watching this video , i had a look at the jet and was all clear so I used a 0.8 mig welding wire and twist it until it went through the soft brass hole and now it has smooth idle and top revs also smooth
Boom cracking job Tony.. I'm pleased my video was able to help you out.. happy mowing
I use a guitar string..bottom E string. I play 12s.been using them for 40 years..
Good idea
(from USA) Hey, I appreciate your patience and clear discussion and speech. I usually have trouble with accents especially British. I usually just replace the carb and throw the dirty one in the trash.
Good job Mick, have the same issue with my husqvarna 675hwt. Will check it out
Tip cleaners for a torch works well also.
Great video Mick!I have that type of engine on a rotorvator, with the same problem.I stripped the carb right down and cleaned everything but didn't realise how important that bowl jet was,so I'll go back and give it a go. Only other thing I could think of was adjustment of the governor.Many thanks.👍
Good luck mate.. hope it works for ya
good fix mick learn something new every day
Well I do try to keep it interesting.. ta for watching cupcake
Love your content mate! Say hi to Riley boy, he’s a legend and such a great energy to the channel :)
Good morning mate .. thanks for watching... Yeah Riley boy is the man
Great video as always mate!! Hope ya'll are doing well.
Yo yo hi mate .. yes thanks doing great here
That’s brilliant mine is hunting and serging but I don’t have a bowl nut jet though.
What do you have
Nice job Mick, I've used this a few times and it worked great, thanks. 👍

Fantastic
Another good job thanks for the videos really helpful and enjoy them cheers mick 👍
Thanks jay mate .. I appreciate your support
This came up with the auto subtitles. “ Hello, I’m Mix Mars Merman” 😂😂😂😂
Bahaha
That comment deserves a "fumbs up"😂
Nice video. I allay wondered how to fix that surging issue. I just checked my carb nut and the hole ended being 0.6 mm. I think the micro bit you used was 0.8 mm. Have you seen them use different sized holes in the nuts for different machines? My mower had a Briggs & Stratton engine.
Yeah I used a 0.8.. not seen any other sizes
Hi Mick. Thank you for this one. I had a late 2016 quantum powered Viking in for poor running. Obviously carb. Stripped and cleaned manually. Not much better. Stripped again. Gave it an hour in the ultrasonic cleaner and manually cleaned it again with carb cleaner compressed air, jet files etc.
Still not much better, until it warmed up.
Tried your fix. Just using jet files to remove some material. Now perfect.
Never known a quantum do that. Just wondering if late models have finer main jet for emission requirements? Only thing I can think of?
Cheers
David.
I think it's just the build up of dirt over the years .. glad it sorted you out.. happy mowing
Helped me thanks
@@tonydellacer7771 no worries
Does the same apply for the newer Briggs & Stratton engines with the plastic carb.?
You can buy I like to change the cartridge
Good video mate. 🙂
Thanks, I learned from the best😉
Clearing the jets solves a lot of issues. Gotta remember that a lot of people watching aren't terribly inclined to try to figure things like that out themselves and this will fix a lot of them. This time of year a LOT of motors are suffering from sitting in the snow all winter🙂
Thanks for watching bill. Hope all is good your end
❤Nice video.
Thank you.
But your mic audio only comes in on the left speaker.
If you put on headphones you only can be heard on the left and you come in very low.
That's strange... I have no idea why
Where can I purchase a replacement one having trouble finding one

This guys a genius. Bought the drills, took less then tens mins to correct the issue. My mowers been into three reputable dealers to try and solve this surging issue and they’ve never solved it. 👍👍👍👍
Boom 💥 good to hear.. fantastic.. I'm so pleased.. happy Mowing
I really hate Briggs and Stratton Nikki carbs. Changing all mine to

I hate it when it when they say it takes 3 or 4 min while I watch a 15 min video that I can't tell half what's he's saying without closed caption with the accent. However great video so thanks for the info sir.
What about when a brand new carb is surging?
Could be springs
@@themowerman do you think maybe I stretched the spring out when I took the old carb off?
@@mhess427 maybe mate
Will this fix sputtering/slight backfire from exhaust on 190cc quantum? Starts, runs fine but has slight subtle backfire through all rev ranges
I would say it will do no harm... Worth a go
GOOD VIDEO. TY
Your welcome my friend
Nice video
Thanks mate
These things must be set from the factory to run with an extremely weak mixture. That drill was removing a few microns of fuel varnish at the most.
Yes.. but that's all it needs to run right ..
Quantum xtl 50 main jet has been drilled out to 1.10mm but still surges. At 1.20mm it runs too rich. Any ideas?
0.08...
@@themowermantried that but it was still surging, I’m thinking either bad fuel or an air leak from somewhere else
@@benc2722 or weak springs
@@themowerman As in the spring between the throttle and the governer?
@@benc2722 yeah sometimes it gets weak and a new spring helps..
Hi Mick. I’m new to small engines but have an engineering back round. Would it be possible to pick your brains. As I have an old hayter harrier 48 I have given it a right birthday but after retuning back to the customer it runs on choke and full throttle only for 60 to 70 secs can’t get it to idle. But before returning it it ran fine for a tank and a half. Carb has been cleaned multiple times. But can’t seem to source a new one. Could you help please. Kind regards John.
Hi mate You after a new carb?
I think to rule it out yes. As I don’t know what else to check.
@@JOHNTUBBY-hr4jh did you drill the jet out.. email me a photo of the mower.. and the make and model sticker. micksmowers01@gmail.com
Hi. I have 2 quantum engines I'm working on. They run good for a minute then run kinda rough. New carbs have not made a difference. When it runs rough if you shake the machine it runs better. Will this fix this problem? They do idle good the problem is more at full throttle.
Well all I can say is give it a go..

Great video, Sir Mick! This video can help a lot of people to understand and fix this issue. 🦅🇺🇸
Thanks mate
Cut your fuel line and install one of Briggs small doughnut shaped fuel filters. It will stop small garbage that plugs your carb from happening hence the surging sound or not running. Change the filter each season.
Carby 😂😂😂😂Australian for carb. Good info though.
Thanks
Ordered a drill set from Micro Mark. Highly recommend them . Drilled the brass like butter. .002” bigger and it is running smooth. Thanks again Mick!
Your welcome.. works a treat don't it
Genius fix. I got the finger drills for less than $3.00. Care is needed but the reaming and cleaning took about three minutes. I'm supposing that the procedure slightly enriches the air-fuel mix.
It just lets a little more fuel in.. mowers nowadays run soo lean..
WHAT YOUR DOING IS WRONG, AND THAT IS GHEATING . THE REAL PROBLEM IS THE FLOAT AND NEEDLE , FOR LONGER USED OF MOWER , THE SEALING ROBBER ON THE FLOAT EXPAND CAUSING THE FUEL TO RUN LOW ON THE CARB. CHANGE THE RUBBER SEAT AND ITS DONE! WHAT YOU DID IS YOU OVERSIZED THE JET SO IT SUCK MORE FUEL!
@@teodorocorrea1060 thanks for the fantastic comment.. question... Did of did it not sort the issue... Was it hunting before? Was it hunting after.. did it fix the problem? Is this something you can do at home? Did it save money compared to buying a new mower or carb?

Good tip
I use carburettor jet files.
Here's my question, can u buy a replacement bowl nut separately from the carb ?
Yes mate .. www.briggsbits.co.uk/acatalog/498981-jet-main-.html
@@themowerman Actually you can get a carb like this for less than $10 US from Temu. I've used several of the China carbs with great results. Have you tried them?
@@joeweiss2409 yeah I have and I have also had some bad response from some of the quality engine performance
What other lawnmowers have this type of jet ( bowl nut jet)? I have an old Honda HRB 475, any chance this has a bowl jet ?
@@mikebarnard2689 no.. your one has a small jet inside the carb..
Mick have followed you for a long time. My Hayter 41 electric start runs but engine makes loud popping noises and does run smooth. What do you suggest is wrong. ?
What engine mate
Thanks, Mick, that is what I am started doing but have not yet finished. I saw Taryl do it and now that I have seen you do it, I will go ahead and use the wire gauge drill bits on it until I get it resurfaced.
Strange? When my Honda mower surge’s it’s a sign that it needs a new air filter.
Yeah that's also a sign..
Mick you do great videos to help others with tips and tricks well done mate
Thanks Hank.. I appreciate your support

Today's ethanol gas is absolute garbage it gums up the carburetors pretty bad I've had multiple lawn mowers that had surging problems I dump acetone in the fuel and just run it eventually it cleans itself out and runs smoothly I've been doing this for over 10 years now it fixes the problem every time I have not Toro carburetor apart yet so far I've been lucky I guess but the acetone breaks down the deposits that are plugging those little portholes
Well just don't use ethanol boosted fuel you have a choice.. Exercise it.
I took a small engine repair class many years ago and the instructor told us to always run the carb dry after each use and to use premium fuel to avoid carbon deposits. Now, I have over 30 years on my B&S Quantum mower without any problems. Just change the oil and replace the spark plug (oh, I just replaced the fuel line out of preventive maintenance). Can’t buy non-ethanol gas in the states anymore.
@@donjohnson3701It costs more but I find non ethanol gas no problem
Acetone is a great way to destroy any rubber or plastic parts in the fuel system. Not that I don't like acetone and laquer thinner, just exercise caution in using them around sensitive parts.
@@anvilsvs yepper it don't take much to fix the problem then you don't have to worry about the plastic or rubber parts
Surging is most commonly caused by a clogged pilot jet or emulsion tube in my experience.
Yes mate
I've just fitted a brand new carb and an in-line filter and it's still hunting/surging and popping noise from the exhaust??
@@kitasaunders carb may need tuning
@@kitasaunders Is the key between crank and flywheel intact and in place?
I use these for the very same reason… works like a charm!
Exactly the same technique as endodontics ( root canal treatment ). Dentists now throw out their nickel titanium super flexible hand files after every use.... they are tapered tho, but cut off the taper and you have a set for free ( if you know a friendly dentist!! )
You can also get really thin welding rod cleaners that are not tapered that are also used for adjusting and filing guitar nut slots
A lot of surging issues are caused by a lean fuel mix, keep in mind your fix, in effect, richened the mixture, there could be an air leak in the fuel/air mix downstream of the carb causing the lean mixture problem! Check the two tiny bolts on the intake tube are tight and there's no air getting past the associated gasket between that and the cylinder head and the "O" ring at the carb end, a quick spray whith carb cleaner while the engine is running will highlight any air leaks ie, the surge will stop or the revs will rise.
Ta for the information.. hope all is good mate
Nice little hack
Thanks cupcake
What size is the drillbit u are using?
0.08.
Hi mick,
Im just trying to learn this small engine repairs, your videos are a great help to me as im trying to look after a bowling club's mower, not been into a carb yet, just a quick question? What would happen if the holewas made a size bigger, thanks
It would run like it was on choke.. so don't make them too big..
Hi Mick, great upload keep them coming. I have been searching the web for a replacement nut as I’m too ham fisted to do the surgery you performed but cannot find anywhere to purchase one. Can you point me in the right direction please?
Here you go mate Briggs & Stratton 498981 Main Jet amzn.eu/d/7T6XY41
Thank you Mick. No wonder you fettle the ones rather than shell out the £20 😂
@@FIamingMoeBUBU lol yes...
Hey mick.... Trick to getting that bowl nut on... Put fiberglass or even some paper towl inside the socket so it holds the nut up but dosent sink down into the socket... Also can try " flushing the carb by taking off air cleaner and run high rpm and covering the intake hole at intervials " sucks the gas right thru...
For some reason I don’t hear audio of you talking on my raycon earbuds… but your intro/outro music I hear. Hmmm
Very good advice there mick . I might invest in those drill bits also
Too long. Too detail.
Lol
Love it when the fix is simple!
Me too.. ta for watching ken..
im here two years after you posted this. bought my first qualcast 35s (do-er uppa) on the weekend. did this and WOW! happy days!. never even looked at an engine before but having watched some of your other videos i can see i will be addicted to this stuff !! cheers pal. new sub! now to replace the bottom blade and sharpen the cylinder!! onwards and upwards!
Rock on!
whats a quid?
One pound
Modern gas requires more fuel to run right, jetting up never hurts anyone.... lol
Great video mate 👍
Thanks cupcake
So simple - and so effective 👍👍
Yeah mate .. it sorts them out..
Thanks for posting! Thought I'd give one last go at fixing my old Honda. The equivalent 'nut' appeared to be inside once I'd removed the bowl, holding in place the main nozzle. Anyway, gave it a really good clean out with micro drills and widened it a little. Running a dream now and hope to get another few years out of it. Thanks again!
You are welcome.. happy mowing
Hey Mick, just a quick question, the mower I’m working on (just a cheap Aldi thing) only surges for a couple of minutes when I start it from cold, then after that it settles down. I know the carb is all good and clean and no air leaks, good fuel etc etc (video will be uploaded later today).
Would you go a step up in the main jet with a tiny drill like this, or would you leave it? some people say drill the pilot for surging, some say drill main?! I’d presume main because it gets to WOT Ok, it’s when it’s there it’s a bit crappy. It just doesn’t look good when a customer comes to view it.
Cheers mate!

Hi Mick got a quantum 5hp which is hunting bad i have cleaned the bowl jet and resized it as you show still hunting so checked for a air leak by putting my hand over air intake and engine leveled out so i have a air leak i have checked the intake pipe which is good no cracked even done a smoke test to try to locate the air leak but could not see anything on the intake only smoke i could see was from the breather with the engine at TDC any ideas please ?
New carb mate ..
@@themowerman It has had 3 different carbs fitted still same problem of hunting
@@M0NXF maybe it's a carb spring issue
@@themowerman Changed the governor spring and rest the governor just in case it had been messed with as i said if i restrict the air flow to the carb it will level out so sucking air past the carb between the carb and valve chest i would think, As a last resort i am changing the inlet manifold just to rule that out .

Cleaned the carb on a Quantum at the weekend. Just sprayed it through with carb spray. It helped it but didn’t cure it. I ordered a set of your drill bits after watching your video 😂😂👍👍
Ok cool.. it should be the orange one but check before you drill.. and remember take your time.. don't snap it off.. let the drill do the work.. let me know how it goes.. good luck
WOW! That hole is small inside there, I didn't think there was a hole at first. I finally found the right bit that went threw, then one size up. You're right, mine was an aftermarket carb bolt. It took some time to go threw. Thanks Mick!!!

Hi Mike, can you please help. B&S 450E plastic carb engine on a 18 month old Hayter 41 Auto drive. Slow starting whatever I do 3 pumps 4 pumps on the red ( hole in the middle plunger).
It does start on pull 4 no black smoke and then runs fine starting every time when warm. Dealer has never come across this issue thinks its a dirty carb I don't see this as it runs great when warm. So first please explain (what does the red plunger do) because I don't see, or hear it squirting like the old side valve BS engine. Also what is the white plastic barb on the side of the carb for, looks like it should not be there. Regards Dave Porter
Email me a photo mate micksmowers01@gmail.com
I started doing this for all of my small engines maybe 20 years ago after ethanol gas leaned them out just a little too much. Technically this is illegal because you're modifying an EPA legal mess which won't run right.
Shhhh it's a secret
I'll have to try this in the spring. My mower started surging even after I took the whole carb apart and hosed it with carb cleaner. That's fixed the problem in the past but it didn't last time and I couldn't figure out why.
Cool let me know how it goes
Hi Mick, I bought the thumb drills and have done exactly as you demonstrate on your film, but the problem with hunting, on my Hayter 41 Quantum, remains exactly the same, if anything slightly worse! What would I have to tackle next, the diaphragm?
