Great video. Now I'm concerned about the carburetor I was working on. First, thinking I knew what I was doping, I bent the tab on the needle holder downer thingy. I know I've got to flaten that back to it's origianl state. Second, I sprayed the whole carb, like a brute beast; first with carb cleaner, then with compressed air from a can. The symptom I was having was the primer bulb wouldn't move any fuel. Fuel lines are good, bulb is good.
Yep! That lack of purge bulb filling is the #1 symptom of a missing or non sealing main nozzle - instead of pulling a vacuum in the metering chamber and thus the needle down and fuel in, it’s just pulling air from the main nozzle lol.
Soaking the carbs, in vinegar : B U T be very time-conscious, as it may / can eat through cheap chinese metal ( pot metal and the like ......). junk metals.
@jamesspalten5977 Not all metals get eaten by vinegar. Molybdenum-stabilized grades of austenitic stainless steel like 316 experience very little vinegar corrosion in most conditions. Nickel-chrome superalloys like Inconel 625 are even more resistant to vinegar, even in high temperature or high pressure conditions. Of course anything plated with 24 karat gold can pretty much last forever in vinegar, but that's more common in electronics than mechanical stuff.
I've used canned air ( Dust Off computer cleaner) in the small ports on carbs. Just don't shake, tilt or turn the can upside down. 409 cleaner is corrosive to aluminum.
Hey Jim! Yep I have used compressed air and carb / brake cleaner in them, you can do so with caution when you’re aware of the dangers and how to avoid damage. The real issue is people just going full tilt boogie 110psi and causing damage :)
I have a echo PB 250 it's ready to be put back together for use. I've looked high and low for the throttle rod. I'm not having any luck. Do you know where I might find one. Thank you
I have a Echo PB 250. Not the LN model. Uses the regular throttle rod that doesn't use the ball throttle on the carburetor. My question is does the carburetor use front and rear gaskets. Thank you

I've stopped rebuilding small carburetors. 90% of the stuff I work on has an aftermarket carb on Amazon for $20 or less. Most of the time they need tuned but I've rarely had a problem.
I've bought about 6 now from Amazon and maybe half of them required no adjustment at all. The price is about 90% off for a Stihl, 70% off for Husqvarnas and a Poulon or two I cannot vouch for, price-wise but they were super inexpensive. I've not had any troubles with the Amazon carbs and they include a whole bunch of new fuel line, the clunk, a new air filter and plug wires where they are replaceable. So if you screw your OE carb up badly enough, all is not lost.
I once rebuilt these carbs, but I found that they were only usually good for one rebuild, if I was so lucky, plus the rebuild kits just keep getting more and more expensive to take a chance on trying to rebuild it and it not solve the issue. Add in taking the chance of dropping and losing one of the tiny carb parts. I not longer feel that rebuilding them is worth my time. If replacing a hardened or split diaphragm doesn’t fix it, I am done and I’m just going to get a cheap Chinese replacement carb. I get them from Amazon so if I get a bad one, I just send it back for a replacement. I personally hate 2 stoke engines and, in this one instance, I will probably replace my 2 stroke leaf blower and weed eater with battery powered next time and just be done with all the two stoke problems!
I know it's tough to find non oxygenated/ethanol free fuel in some areas of the country. But if you can get it, it's the key for two cycle, well really any small engine longevity. I've got a cheapo 25 ish year old 25cc craftsman string trimmer I've had since new. It starts with a couple few pulls every time even in the spring after sitting for six months all winter. And I've never touched the carb. I've always used non ox premium fuel mixed with AMSOIL Saber 100 to 1 two cycle oil. That Saber oil helps preserve the fuel as well. About a year ago it wouldn't start, so if figured probably the spark arrestor screen was plugged. Nope, pulled it apart and the screen was clean as a whistle! Fantastic! Had pulled the spark plug prior to that and it looked decent too. But it turned out that original plug had finally shorted out internally. Not bad for a 25 year old two cycle spark plug huh? I've found AMSOIL products to be fantastic and I use them in all my stuff, cars, truck, small engines, motorcycle, outboard, snowmobile, everything.
@@429thunderjet2 yes, my favourite 2 stroke oil is Amsoil Saber. I run it at a bit higher oil ratio at 65:1. I also agree, the best thing for 2 strokes (apart from alkylate fuels) is non ethanol - just straight unleaded. Thankfully where i am in Western Australia, there is no such thing as ethanol :) other states here in Australia they’re not so lucky!
If people with two stroke power equipment would use Sabre oil fr Amsoil,it mixes at 100:1,saves a shit ton of two stroke problems. I’ve been using Sabre oil for about 8 years,my equipment cranks first or second pull all the time,also mix with Non ethanol fuel.
Ive always wondering if by using a syring, gauge, and super small vacuum cup if there was a way to test the check valve for proper operation. Im just now coming across your/this video and curious on your thoughts. Unless you have covered this in other videos then please let me know. Oh, and one last thing, what are symptoms of this check valve being bad. Thanks a million in advance.
@VintageEngineRepairs Okay gotcha, and i would use one of those cheap suction cup vises and im talking bout a bigger style syringe (plastic). I also have pretty small suction cups that accept tubing so whether pressure testing or vacuum testing. It was justa thought but i can say you covered this checkvalve in a amazing way, this was the only thing i have always wondered what was going on and how with so awsome job. I just like making up tools for testing things so there is never any guessing, i just like to prove something wrong, im weird like that,,,lol
Thanks for making this video. I've cleaned carbs out for years and nothing like this dawned on me. You recommended soaking the carb. What do you recommend soaking it in so itll clean it?
Thanks for your extremely helpful and insightful video! Question: On 2:26 you show soaking the carb in some kind of fluid. Could you please explain which cleaning material your using? Thanks a lot.
might you show what to look for in a good ultrasonic cleaner that I have seen you use? from what I have seen, it obviously works well! Thanks. Love your channel.
I appreciate deeply your videos. I would love to hear your take on the non adjustable carbs on the MS 170 and 180 chainsaws. I have one that bogs and I've replaced metering and valve diaphragms but no difference. Can't get at the jet channel as there is no screw visible. Any advice appreciated.
Yes, I’m not a fan of them as they’re not adjustable, if you do a search for “WT215 ms 180 conversion” you can see how it’s possible to add an adjustable carb to one :)
Never use anything with acetone or toluene , like what's in carb cleaner. It will swell the rubber check valves in the carb body and ruin the carb. Use chlorinated brake cleaner aka non flammable brake cleaner and an ultrasonic cleaner.
@@VintageEngineRepairs I found a twist cap 3 line head on fleabay that works a treat. It takes 3 crossed 130 square lines and just eats Johnson grass for lunch on a 2620t echo.
@@VintageEngineRepairs Thanks for the reply... After some research it appears mine is a diaphragm. Which means i've probably blown it out long ago. Time to buy a new nozzle. Thanks again!
@@VintageEngineRepairs My WT-682 had a diaphragm! I was able to 3d print one from TPU @ 0.2mm height and it seems to be working :) Ps... you channel is an absolute gem, and your approach to the topic and videos is very enjoyable. Subscribed!
That’s crazy I had no idea you can 3d print diaphragm material. And it fuel resistant? Can you link me to a video of the process? I saw someone mention this on arboristsite too, is that you? Thanks for the kind words :)
@@VintageEngineRepairs Yeah, thats me..same guy! Honestly not much to see. it looks like any 3d printing. Trick is to use TPU which a a rubber like material with decent chemical resistance and get the diameter vs thickness right. Also, there are different 3d printing surfaces, in this case you want a smooth one for the matting surface side of the diaphragm. If you want to send me an address through arborist DM ill send you an envelope with a bunch of different sizes you can test. Ill send them by stamp mail so will cost nothing even across the ocean....also, after tuning the carb the 3d printed diaphragm appears to be working pretty much fine.
I purchased a cheap (reverse engineered chinese) replacement carb for my stihl strimmer from amazon. The head will only run and strim with the throttle lock on. As soon as I play with the throttle trigger it coughs and dies. What is the cause of this? Others have reviewed these carbs and not had a problem.
Hey :) you’ll see from my other replies to people’s comments, I never recommend Chinese copy carburetors, they’re notoriously unreliable. However you may just need to tweak yours. Have a watch of my video on how to tune a carburetor - ua-cam.com/video/UyngDl_2km0/v-deo.html

Crazy timing this. I've been fooling around with the carb on my Stihl MS180C. It has no mixture adjustment screws, only idle. Bogs down off idle. I suspect the metering diaphragm, a little "clicky", and the dealer has to order it. So, a couple questions. What is a good safe cleaner to use in the ultrasonic? 409 turns the metal dark. 2. Do you trust the parts available thru the internet? Seems kinda hit n miss in my limited experience.
I have used Seafoam and 2-Stroke mixed fuel, about half and half. Gasoline is a good cleaner by itself and so is Seafoam. I've also used Berryman B-12 and the fuel mix. Both ways seem to work well. (I wouldn't recommend smoking around the cleaner, though.). I've also used Super Clean mixed 8:1 with hot distilled water on some small, really greasy items. (The Super Clean is probably the "Safest" alternative of those.) I have to admit that I have never used the actual stuff made for ultrasonic cleaners. When I clean my wife's jewelry, my electric razor's blades and parts, or watch bands, I use about 2 tablespoons of ammonia with the balance (about quart) of distilled water. You can see all of the dead skin cells sort of explode into a cloud. I've also used just distilled water for some items and even that works to a certain extent.. I don't get too crazy because it's my wife's jewelry cleaner, after all. As long as her Wedding ring sparkles, she's happy. The rest, she doesn't have a "Need-To-Know". I'll probably get her a new one as a gift soon and just move this one to the garage. It does a fine job on small parts.
@@sieggs25 hmm - what’s the history of the machine? How did you come across it? When did the tune change or problems start? What fuel do you run? What work have you done to it?
@@VintageEngineRepairsthe machine is 15 years old. It was getting a bit hot than usual. The valves were adjusted, purge bulb replaced and carburetor gasket replaced.
I really appreciate you using, and the noticed effort to use the English pronunciation of carburetor instead of the English pronunciation of carburetor.
..."if you use compressed air, use it Very Lightly".... I Must be 1 Lucky S.O.B then ! Cuz wen I'm cleaning 1 of my carbs, Im using a LOT of air ! My air compressor builds up to 185psi & Im giving every hole I can find a Good Blast of air.... And All my machines are still running like new! Maybe I'll go buy some lotto tickets !
Inlet barb in the case it's plastic, is probably cracked and leaking. The metering diaphragm needs to be soft, not hard and stiff, else it's going to oil-can and fuel control will be rich one moment and lean the next.
@@VintageEngineRepairs2:44 inlet barb? Perhaps somehow we aren't discussing the same subject? BTW, plenty of 2-strokes are fitted with a float-style carburetor, the carb type (float/diaphragm) has nothing to do with being a 2 or 4-stroke.
I don’t want to waste my time to clean carburetor’s and fuel system . Since I used Acylate(blue 4stroke,orange 2 stroke)fuel or aircraft fuel (100LL ore 91/96 UL). I never ever hade a problem the last 50 years apparently ! Yes it’s more expensive but how much fuel do we need ??? Don’t use the junk from the gas station especially when the engines sits unused for a long time !
You have to be quite careful with what you use to clean 2 stroke Diaphram type carbs , Some Carb cleaners are such a strong chemical detergent they will dissolve or swell up the tiny flappers within the carbs check valves turning them into a globs of goo. some carbs have replacable check valves ,, Some are of a design where they can not be replaced requiring you to replace the whole carb as a unit once this happens ,, so take care with what cleaning chemicals you use. two stroke carbs that have a primer will have tiny check valves on both the low speed and high speed circuts as well is in there primer housing.. use something like wd40 not Gumout choke and carb spray , search on check valves and preasure testing testing on youtube..
Yep you can, but you can’t buy a new oem carburetor for anywhere even close to a kit. Look after them, don’t store ethanol in the tank or engine - run them dry and you’ll never have a problem. Chinese carburetors are notoriously unreliable.
@@VintageEngineRepairs it's basically like a motorcycle carby. Has a plunger that goes up as you accelerate with a metering rod which you can change to different sizes. In my case I put a lightweight oil almost like wd40 in the top housing screw. Worked great on a straight GMH ( aussie version) General motors) 3.3 litre engine with a GTR XU1 internals. Very responsive and it would recommend hard! 😆 lol. Like all the time. Cheers 🙂
Who cares about carbs anymore. Been a technician for forty years. Still working in the automotive industry. Fuel injection and now direct injection is the way everything has gone. Carbs were my thing back in the day. Everyone brought there car to me to fix the carb, even other shops from the county I worked in. Progress caused the downfall of carbs and they are dead now. They offer no advantage over fuel injection and waste a lot of fuel even when properly tuned. Any engine can be retrofitted to fuel injection now.
Chinese aftermarket carburetors are indeed cheaper, but are also notoriously unreliable, often leading to more problems than you’ll solve. To replace this OEM carburetor with a genuine Zama the same specification you’d spend $150-$200. A simple carburetor clean and new kit is just a few dollars and few minutes of your time. To me it’s worth saving the OEM.
@@VintageEngineRepairsI've purchased four cheap Chinese carburetors off of eBay. They all lasted as long or longer than the original Stihl carbs! Plus they had adjustable jets!
Soaking the carbs, in vinegar : B U T be very time-conscious, as it may / can eat through cheap chinese metal ( pot metal and the like ......). junk metals.
total bollocks remove the air filter rev the thing up and slap your hand / or a bit of card over the intake , remove it before the engine stalls and repeat a few times . any crap stopping the valves in a 2 stroke engine should be sucked through under the extream vacume you just created by blocking the air intake off [ this works on 4 stroke engines too ]
Sigh. Good advice for the morons out there. It's so simple to just buy a service kit, strip, gently soak and clean and dry, set up, and get a reliable running motor. But a whole new carb seems way overkill.
Experience. Unless they changed them in the last year it's the most replaced stihl part at our local dealer. And we are just one little home town dealer. @@VintageEngineRepairs
Stihl do not make carbs they use Walbro, zama or Tillotson, I have Stihls that are over 40 yrs old and I have new Stihls they all have their original carbs and run fine. I would suggest its the mechanic doing the servicing and not the equipment!
You look like a bunnings worker. Prices are going sky rocket 🚀due to Trump tax buying a new carb isn't the answer ! Disassemble it all and into a sonic cleaner you go

@@jessiegoss7660 so true 🤣
LOL. I actually avoided for once in my life after reaching the age of 56.
Cleaned my first carb today, got a really close call with the carb cleaner hitting my eye
An hours worth of labor at a shop, say $80 versus a ebay $25 carb. 🤔 Bad thing is the fuel we buy today is ruining a lot of small equipment.
Only takes 7-10 mins to disassemble, clean and rebuild one!
The idea is to read the users manual to see what fuel to you use! NEVER use ethanol blended fuel in the older type carburettors.
Even using regular ethanol free pump gas you need to rebuild the carbs

@@VintageEngineRepairs I found a twist cap 3 line head on fleabay that works a treat. It takes 3 crossed 130 square lines and just eats Johnson grass for lunch on a 2620t echo.
Useful information. Thank you so much.
You’re welcome :)
Do you know if the wt walbro series has this diaphragm? thanks, your videos are extremely helpful!
Some have a ball valve others have a diaphragm, but I don’t know the specifics for each model I’m afraid!
@@VintageEngineRepairs Thanks for the reply... After some research it appears mine is a diaphragm. Which means i've probably blown it out long ago. Time to buy a new nozzle. Thanks again!
@@VintageEngineRepairs My WT-682 had a diaphragm! I was able to 3d print one from TPU @ 0.2mm height and it seems to be working :) Ps... you channel is an absolute gem, and your approach to the topic and videos is very enjoyable. Subscribed!
That’s crazy I had no idea you can 3d print diaphragm material. And it fuel resistant? Can you link me to a video of the process? I saw someone mention this on arboristsite too, is that you? Thanks for the kind words :)
@@VintageEngineRepairs Yeah, thats me..same guy! Honestly not much to see. it looks like any 3d printing. Trick is to use TPU which a a rubber like material with decent chemical resistance and get the diameter vs thickness right. Also, there are different 3d printing surfaces, in this case you want a smooth one for the matting surface side of the diaphragm. If you want to send me an address through arborist DM ill send you an envelope with a bunch of different sizes you can test. Ill send them by stamp mail so will cost nothing even across the ocean....also, after tuning the carb the 3d printed diaphragm appears to be working pretty much fine.
Lower pressure and kerosene! Subbed and liked 👍 ❤cheers from Australia
Hey! Thanks :) glad you enjoyed it - yep kero is awesome!
I purchased a cheap (reverse engineered chinese) replacement carb for my stihl strimmer from amazon. The head will only run and strim with the throttle lock on. As soon as I play with the throttle trigger it coughs and dies. What is the cause of this? Others have reviewed these carbs and not had a problem.
Hey :) you’ll see from my other replies to people’s comments, I never recommend Chinese copy carburetors, they’re notoriously unreliable. However you may just need to tweak yours. Have a watch of my video on how to tune a carburetor - ua-cam.com/video/UyngDl_2km0/v-deo.html
Echo chainsaw won't stay started rebuilt the walbro hda carburetor what else can it be
It’s way too broad of a question I’m afraid, start with the basics - fuel, ignition, compression.
Got compression and spark just no fuel starts with starter fluid
Your thumbnail game is good, I’m gonna need to step it up🤣
Hahah, thank you mate 😂👍
Absolutely wonderful to have found your channel, the content you provide is amazing and invaluable, keep up the amazing teachings you share with us. By the way, where do I find the fuel bottle you showed on this video? Please provide a link for it.
Thank you!
Thank you for the kind words!! You’re very welcome. They are found online, it’s quite tricky to find this brand in the USA, therefore I recommend you search “zoom oil bottles”. If you’re in Europe or Australia you can get these and they’re called Pressol Oil Bottles.
Thanks again!
Absolutely and completely thankful for the provided information and your fast response!
There are many UA-cam podcasters that show off their skills and products and they don’t have the decency to provide information about them, and when asked they don’t even respond… the funny thing is that they do request a 👍 like and subscribe plea. The joke is on them, for more informative the video is I refuse to subscribe to their channel. 🤣🤣🤣
Again, much Thanks!!!
Haha I do my best and after all these videos are for YOU not for me! I want you guys to enjoy them and for me to be able to interact with my audience. I do my best to reply to every message but I do get a bit overwhelmed from time to time. The financial reward of doing these videos for the time that goes into them is not worth it, but comments like yours make it so :)
Great video and information 👍
Thank you! Glad you enjoyed it :)
Nicely done.😎
Thanks :)
Thanks for this!
You’re very welcome :)
Nice fuel bottle. I'm trying to find one on Amazon, but no luck. Do you have a name or manufacturer for it?
I found something similar. Is this the same as you have.
mnpctech 8oz (500ml) Honda Civic Accord Transmission Fluid Refill Dispenser Squeeze Bottle with Brass Tube
Cool! Looks very similar! Just check it can hold gasoline :)
See my other reply below ha sorry
Also this one looks similar. STAHLWILLE 12251 Oil squeeze bottle.
Very good explained bin fixn this stuff for years I'm glad you fix it not replace it
Thanks :) you’re quite right, I agree and always rebuild and repair rather than just replace. Glad you enjoyed it!
Crazy timing this. I've been fooling around with the carb on my Stihl MS180C. It has no mixture adjustment screws, only idle.
Bogs down off idle. I suspect the metering diaphragm, a little "clicky", and the dealer has to order it.
So, a couple questions. What is a good safe cleaner to use in the ultrasonic? 409 turns the metal dark. 2. Do you trust the parts available thru the internet? Seems kinda hit n miss in my limited experience.
I have used Seafoam and 2-Stroke mixed fuel, about half and half. Gasoline is a good cleaner by itself and so is Seafoam. I've also used Berryman B-12 and the fuel mix. Both ways seem to work well. (I wouldn't recommend smoking around the cleaner, though.). I've also used Super Clean mixed 8:1 with hot distilled water on some small, really greasy items. (The Super Clean is probably the "Safest" alternative of those.)
I have to admit that I have never used the actual stuff made for ultrasonic cleaners. When I clean my wife's jewelry, my electric razor's blades and parts, or watch bands, I use about 2 tablespoons of ammonia with the balance (about quart) of distilled water. You can see all of the dead skin cells sort of explode into a cloud. I've also used just distilled water for some items and even that works to a certain extent..
I don't get too crazy because it's my wife's jewelry cleaner, after all. As long as her Wedding ring sparkles, she's happy. The rest, she doesn't have a "Need-To-Know". I'll probably get her a new one as a gift soon and just move this one to the garage. It does a fine job on small parts.
I really like ct14 if you can get it! Best of luck with the 180, they’re awesome saws!!
@@tinkerscorner54thanks for sharing what you know!! :)
409 is corrosive to aluminum and some other metals. That's why it turned your carb black.
@@tinkerscorner54 Thank you! 👍🍻 Good to know. Have heard good things about Seafoam.
Great video!
Thank you!
What can be the cause of more fuel consumption? Stihl FS 100 weed eater
Having the carburetor set too rich 👍🏻
@@VintageEngineRepairs haven't touched the factory settings but will check. How do I check if it still has the factory settings?
@@sieggs25 hmm - what’s the history of the machine? How did you come across it? When did the tune change or problems start? What fuel do you run? What work have you done to it?
@@VintageEngineRepairsthe machine is 15 years old. It was getting a bit hot than usual. The valves were adjusted, purge bulb replaced and carburetor gasket replaced.
good info ,thanks man
You’re welcome)
great advise
Thank you :)
I really appreciate you using, and the noticed effort to use the English pronunciation of carburetor instead of the English pronunciation of carburetor.
Thanks for watching!
Good info Tom .
Thanks Pete :)
Great advise Tom 👌👍
Thanks Nev!!
..."if you use compressed air, use it Very Lightly"....
I Must be 1 Lucky S.O.B then !
Cuz wen I'm cleaning 1 of my carbs, Im using a LOT of air !
My air compressor builds up to 185psi & Im giving every hole I can find a Good Blast of air.... And All my machines are still running like new!
Maybe I'll go buy some lotto tickets !
Maybe you should haha. Thanks for watching :)
Inlet barb in the case it's plastic, is probably cracked and leaking. The metering diaphragm needs to be soft, not hard and stiff, else it's going to oil-can and fuel control will be rich one moment and lean the next.
Sorry I’m not sure what you’re referring to? This video didn’t mention any of those things! Thanks for watching!
@@VintageEngineRepairs2:44 inlet barb? Perhaps somehow we aren't discussing the same subject?
BTW, plenty of 2-strokes are fitted with a float-style carburetor, the carb type (float/diaphragm) has nothing to do with being a 2 or 4-stroke.
Oh yes but referencing avoiding shooting air through it 👍 I think you may enjoy this video - ua-cam.com/video/_4K6dBQTeek/v-deo.html
@@VintageEngineRepairs I'll watch it if it involves removing the Welsh plugs, a required task for a proper carb overhaul.
I think you’ll enjoy it ;)
Wish I'd watched this in advance of cleaning my carb :)
Haha, at least you know for next time :)
We would not have these issues with carburetors if it were not for the EPA!!!
I’m not so sure! These issues have been around long before EPA :)
No but you'd have lung problems instead
I need to put my bolt an spring back on mine a mechanic well a pose to be mechanic took mine apart never put it back
Ah sorry to hear it! It’s a fairly simple process, keep me updated with how you go :)
I have replaced 2 carburetors for under $20 each
I prefer keeping the OEM carburetor and just paying a few cents for a carburettor kit.
Spraying carb internals is very 1998, long live the ultrasonic 😁
LOL! It’s certainly a safer way, but not always practical 😂
@VintageEngineRepairs For people who don't do a lot of carbs, it's a bit pricy. I told my wife it was a jewelry cleaner. 🤣
@@GuysPlayingWithTools I actually use my wife's Jewelry cleaner. I clean it up before I sneak it back in. Shhhhhh . . .
@tinkerscorner You can move it to the garage and tell her you are doing for her, so she doesn't have to listen to the noise while it's cleaning, lol
@@GuysPlayingWithTools😂
I don’t want to waste my time to clean carburetor’s and fuel system . Since I used Acylate(blue 4stroke,orange 2 stroke)fuel or aircraft fuel (100LL ore 91/96 UL). I never ever hade a problem the last 50 years apparently ! Yes it’s more expensive but how much fuel do we need ??? Don’t use the junk from the gas station especially when the engines sits unused for a long time !
That’s all good :) we all have our preferences! Thanks for watching 👍👍
You have to be quite careful with what you use to clean 2 stroke Diaphram type carbs , Some Carb cleaners are such a strong chemical detergent they will dissolve or swell up the tiny flappers within the carbs check valves turning them into a globs of goo. some carbs have replacable check valves ,, Some are of a design where they can not be replaced requiring you to replace the whole carb as a unit once this happens ,, so take care with what cleaning chemicals you use. two stroke carbs that have a primer will have tiny check valves on both the low speed and high speed circuts as well is in there primer housing.. use something like wd40 not Gumout choke and carb spray , search on check valves and preasure testing testing on youtube..
Thanks for watching and sharing 👍
E10 destroys carbs. I can buy a new carb, cheaper than a kit..
Yep you can, but you can’t buy a new oem carburetor for anywhere even close to a kit. Look after them, don’t store ethanol in the tank or engine - run them dry and you’ll never have a problem. Chinese carburetors are notoriously unreliable.
Almost as easy as triple SU carbys ! A gunson metering air took to balance them.
I haven’t worked on SU carburetors, but good to know :) thanks for watching!
@@VintageEngineRepairs it's basically like a motorcycle carby. Has a plunger that goes up as you accelerate with a metering rod which you can change to different sizes. In my case I put a lightweight oil almost like wd40 in the top housing screw. Worked great on a straight GMH ( aussie version) General motors) 3.3 litre engine with a GTR XU1 internals. Very responsive and it would recommend hard! 😆 lol. Like all the time. Cheers 🙂
@@dragan3290 ahhhh! A slide carburetor! Gotcha :) thanks for that.
A new carb kit with gaskets, fuel line, and fuel filter is only $20. My time is more valuable than taking it apart and cleaning it.
The carb kit doesn’t contain the main nozzle. A carb kit won’t solve this issue.
Sonic vibrater
Yes an ultrasonic cleaner is handy :)
Who cares about carbs anymore. Been a technician for forty years. Still working in the automotive industry. Fuel injection and now direct injection is the way everything has gone. Carbs were my thing back in the day. Everyone brought there car to me to fix the carb, even other shops from the county I worked in. Progress caused the downfall of carbs and they are dead now. They offer no advantage over fuel injection and waste a lot of fuel even when properly tuned. Any engine can be retrofitted to fuel injection now.
Thanks for watching
Those carburetors are so cheap that it is not worth fixing them , just buy a new one!!!!
Chinese aftermarket carburetors are indeed cheaper, but are also notoriously unreliable, often leading to more problems than you’ll solve. To replace this OEM carburetor with a genuine Zama the same specification you’d spend $150-$200. A simple carburetor clean and new kit is just a few dollars and few minutes of your time. To me it’s worth saving the OEM.
@@VintageEngineRepairsI've purchased four cheap Chinese carburetors off of eBay. They all lasted as long or longer than the original Stihl carbs! Plus they had adjustable jets!
@@jimkarban6489I've bought a number of chinesium carbs supposedly for the engine in question and they are never the same.
do not use spray, dunk it instead
Sure thing 👍
U Didn't say ANYTHING about the Screw on the Inside
Which screw?
110 psi ....got it
🤣🤣
Order a carb while you can!
Thanks for watching
Soaking the carbs, in vinegar : B U T be very time-conscious, as it may / can eat through cheap chinese metal ( pot metal and the like ......). junk metals.
Thanks for watching
Probably half or better of the driving Public now doesn't know what a carburetor is.
At least! That’s ok though, I use a lot of things I don’t understand :)
👍👍👍
Thanks :)
total bollocks remove the air filter rev the thing up and slap your hand / or a bit of card over the intake , remove it before the engine stalls and repeat a few times . any crap stopping the valves in a 2 stroke engine should be sucked through under the extream vacume you just created by blocking the air intake off [ this works on 4 stroke engines too ]
Thanks for watching
How to how to suck carburettor
Huh?
A♠'s
Thanks mate :)
Sigh. Good advice for the morons out there.
It's so simple to just buy a service kit, strip, gently soak and clean and dry, set up, and get a reliable running motor. But a whole new carb seems way overkill.
Thanks for watching
Stihl carbs are junk.
What is the merit behind your comment?
Experience. Unless they changed them in the last year it's the most replaced stihl part at our local dealer. And we are just one little home town dealer. @@VintageEngineRepairs
@@gsxr419 that’s not been my experience, they’re fantastic.
Stihl do not make carbs they use Walbro, zama or Tillotson, I have Stihls that are over 40 yrs old and I have new Stihls they all have their original carbs and run fine. I would suggest its the mechanic doing the servicing and not the equipment!
@@pavelrobertson5016 not the older stuff just over the last 5-7 years or so.
Can someone please translate this into American?
You look like a bunnings worker.
Prices are going sky rocket 🚀due to Trump tax buying a new carb isn't the answer !
Disassemble it all and into a sonic cleaner you go
👍🏻👍🏻
