The metal disc is part of the diaphragm. It is the part that makes contact with the metering lever. The metal disc should face down or toward the carburetor body. You are correct about the gasket. I'll admit it... I made a mistake. The diaphragm should be above the gasket. The proper reassembly order is, from carb body working out, gasket, diaphragm, cap. Sorry for the confusion. -Mark
I have cleaned a lot of these with no results until I started removing the screen and cleaning under it. Makes all the difference in the world. Small engine mechanic tipped me off on this. Bend a pin and grab the side of the screen. Comes out easy if your lucky and no damage.
I am glad to see you mentioning the spring that loves to go flying. First time I took apart a dead carb to see what makes it tick that piece almost hit me in the face and I never found it in the garage again
As an added tip. . .I've found that I can use a thin sewing needle to physically go into the orifices and clean out any gunk that's been built up. . mainly from ethanol treated gasoline (which is a bad idea to use in carburetors). Quite often carb cleaner simply won't clean out these orifices totally. I spent a LOT of time going through the pangs of trying to get string trimmers and later, chain saws , running until I was schooled on the problems with ethanol additives. It's a major hassle. If you can get 100% gasoline, it's highly recommended that you use it in your 2 and 4 cycle engines. There's a class action lawsuit involving small engine builders against this gas. Unfortunately, it's often the only thing available. Nice video. Well stated.
One thing I would additionally recommend is that you protect yourself from contact with the carb cleaner and, in fact, all similar chemical. They will have a cumulative negative impact on all bodily systems especially the kidneys, liver and nervous system. Moreover, they could possibly be carcinogenic and, like many carcinogens, the resulting cancer might not appear until decades later.
Great video...My TroyBilt weed wacker wouldn't start so I followed your instructions and cleaned the carburetor. Voila, it started right up. So now that I felt confident, I pulled out my Craftsman blower that quit running last summer. When I removed the carburetor I noticed the fuel lines were cracked. I cleaned the carburetor, replaced the fuel lines and it wouldn't start. The cylinder sleeve was loose so I tightened it up and she fired right up. Thanks eReplacementParts,
thanks for the video Mark. Its very instructive to people like myself. It helps people like me that needs a little instruction on the simple repairs that drive me crazy every spring. Also I was told to use non-ethanol fuel at the local co-op to keep debri down in the carbs on my small engines.
Thank you! Had a Stihl FS 55R that wasn't working... came across this... demystified the process for me, and 30 minutes later it's running like new. Thanks again!
A very well presented video but, I have went through this cleaning procedure and sometimes it just doesn't work. I even tried soaking the carb in carburetor cleaner for days. Didn't work. What finally did was taking a tip from a long time small engine mechanic Basically, after removing all rubber parts, you boil the carburetor in a strong solution of Tide detergent. Apparently, varnish can be so tough and plentiful that a little spraying or even soaking in carb cleaner just won't do any good. I even tried going through the portals with guitar wire as was suggested by one mechanic. When I got through boiling one carb that I was having problems with, after trying everything in this video and more, I ended up with a skim of something on top of the water which I took to be more varnish. Once put back on the engine, it ran like a top.
***** Justin, I just can't tell you exactly as I didn't take note of how much I put in. Maybe a couple of tablespoons, (not soup spoons) for a 1 1/2 quart pot. I can say that you need to have the Tide thoroughly dissolved before putting in the part. Also, make sure rubber or gasket parts are taken off. In addition, make sure the carburetor is thoroughly rinsed off after removing. The best way is transfer the carburetor to clean hot water, boil it for a for a minute or two then thoroughly rinse off with cool water as soon as you can. You want to make sure you don't leave any detergent in the carburetor as it will stop up the ports/passageways as well. Good luck.
Great video - thanks for the information. Question: In section 130-150 of the video the removal layering of the diaphragm gasket would appear to be carb->gasket->diaphragm->cover. In section 733-745 of the video you show the reassembly as carb->diaphragm->gasket->cover. Does the order matter?
Great video, thanks for sharing it. I've got a 3 year old trimmer that purred along last year and won't start this season... and your videos should help me get it running again.
Nice video, It was fairly accurate except for the diaphragm gasket. You will also need to break the plastic anti tamper piece off the Hi and lo mixture screws and clean them. Just take note on how far they were turned out.
Ryobi generally use carbon copies of Zama carbs, in this instance I believe a set of diaphragms and gaskets are available for this carb under Zama part no. GND-18
Hey mark I work at a lawn mower parts store and I came to realize that for the rhino carburetors the Zama carburetor kits with part number Gnd-12 or Gnd-18 have worked for my customers. Try it!
Thanks this helped me fix a badly running chainsaw (clogged spark arrester screen) and a non starting strimmer. (new spark plug) clear and methodical instructions. Nice.
Both my weedeater and blower died on the same day. I'm thinking it might have been some bad gas/oil, but I switched to the trufuel to try it and it tries to fire a lot easier, but now is time to clean the carbs. Thanks for taking the time to make this video. Wish me luck! lol, damn it.
Thank you SO much. someone gave me a multi tool engine and i watched your videos closley practicing on the engine the guy gave me. i've stripped it,cleaned it and now waiting for the new primer bulb to arrive so I can start the engine. Your videos are straitforward ,clear and helpful. I thank you for that,now i know a lot about 2 strokes in just few days. Happy :)
Excellent video and instructions,very clear and easy way to get it right,and if one cannot follow this simple instructions,perhaps shouldn't touch the carb.
It sounds to me like one of the gaskets or the reed valves may have been reassembled upside down. This will block the carb passages, basically stopping fuel flow through the carb. I hope this helps, -Mark
Does anyone notice how red his knuckle joints are? Be cautious if you want to keep healthy lungs, spray with adequate ventilation and outdoors preferably, try to contain drain off fluids if possible, if you want to keep your hands, wear chemical resistant gloves, and lastly invest the meager 1.88 for a pair of safety glasses to protect one of the two most vital assets you possess before using such chemicals as Acetone, Xylene. Toluene, Methyl Ethyl Ketone (MEK), Ethyl Benzene, 2-Butoxyethanol, and propane. Most of these 'ingredients' are present in carb cleaner. Take a moment to read and understand any labels. Cheers!
I noticed that the high and low needles weren't removed for this cleaning. Isn't that required for a thorough cleaning? I believe that carb cleaner contains MEK which is highly carcinogenic, rapidly absorbed through the skin and is associated with liver cancer (hepatocellular carcinoma) with long term or repeated exposure.
Excellent video, and was vey helpful in repairing the carburettor on my line trimmer! However, I must make a few comments. Always wear safety glasses when using compressed air, aerosol cans, or when disassembling springs. A spring may indeed "fly across the shop" and disappear, but it may also fly up and hit you in the eye. Compressed air (even at low pressure) can relocated dirt and debris into your eye with serious consequences. A good pair of safety glasses will cost you $5.00 so it is money well spent. Cheap disposable gloves are also a good idea when using cleaners or solvents! Otherwise, thanks for the tips.
Is there a video of yours that explains how to adjust a carb without a tach? I've been trying and trying on this Stihl I have but just can't do it. I took it to the local shop they wanted four days! For a five minute job! I have the special flat end screw driver Stihl has to do it too. Thier factory settings of one turn out are fine if the saw just idles, but if I run the saw through one peice of wood it never idles down.
Thank you for the video showing how to service a small carburetor, the problem I have with mine is when I start it and let it warm up as soon as I try to speed up it just splutters and stops, I have sprayed carb cleaner in it but still no good, any help would be brilliant.
Great video helped a lot but you might want to press the use of safety glasses when using carb cleaner it burns like hell when you get as much as the mist in your eyes so guys and gals use safety glasses again great video thanks my unit runs great.
@Mr70Cenzo Great suggestion. I have a box on my bench but it seems that in the heat of the repair I never remember to put them on! Thanks for watching, -Mark
@AmoureuseTouti You're very welcome, AmoureuseTouti. To be able to answer your question about your pressure washer more specifically, we'd have know your machine's model number to find out if pump assemblies for that model are currently available from the manufacturer. Feel free to post your washer's model number here or head over to eReplacementParts*com and use the model number search. The model number search will take you to your washer's parts page and breakdown schematic.
Ryobi may not offer a rebuild kit for the carburetor, but the carb is probably made by Walbro (or some other carb mfg.), not Ryobi. Usually, the carb mfg. & model can be found on the carb body, which will allow for the proper rebuilt kit to be obtained. Most small engine shops have, or can get carb rebuild kits, or carb rebuild kits can be obtained from on line small engine suppliers.
Hey Mark, I just followed this video and got my Ryobi running again--but now it will only run at full choke, and it runs at full RPM. Any ideas for me?
I have been running 100low lead aviation gas in my 2 strokes for years.. Never a problem if carbs are clean to start w/ and proper maint is maintained.
I'll be doing this over the weekend! My ryobi CS30 will only run after being primed... as soon as I give it throttle, it will bog down and run slower and slower and die.
I'll be doing this over the weekend! My Ryobi CS30 will only run after being primed... as soon as I give it throttle, it will bog down and run slower and slower then die. I'm guessing that carb is gunked up.
You need to correct this video.The diaphragm gasket goes on first then the diaphragm then the cover plate. No way the engine will run the way you have it now. I think you got it mixed up with the reed valve. It goes reed valve, gasket then plate.Other than that the video is great.
I will watch the videos you have a few more times. One thing I noticed is that my carb does not have the white/red/black plastic piece on it like yours does under the choke lever.
I have a echo pb2100 leaf blower. It starts and runs but when I give it gas it boggs down but still runs. does the carb need to be cleaned? or is it in the idle screws. Gragg Cain
just randomly stumbled on this video. I bet you can put any of the walbro carburators for go peds on there. all those engines are 23-29cc. Looks like the same bolt pattern, Or even use their rebuild kits if the one in this video is a Walbro. It sure looks like one.
My 2 stroke troy would not start. Wasted time changing lines and filter. Watched video, do as Mark says. Make sure to clean the small screen found on the carb. It is usually clogged and that is the problem for not starting. Ethanol found in gas clogs the small holes and lines so I now use the pre mix which has no ethanol. Mark thanks much, mazeltov.
on the inlet where the gas line connects to the carby, just shoot some compressed air into it and the little screen will come out. then just push it back in when it is clean. also, carburator cleaner can ruin the pieces as i have found out the hard way
To be safe, could you put the unit in a Ziplock bag when removing and replacing the needle assembly? Or loosely wrap it in plastic wrap. That way, you could see what you are doing but if the spring got loose, it wouldn't fly across the room.
FYI...Wear your PPE's when doing instruction videos. Just in case, your PPE's are your Personal Protective Equipment such as nitrile gloves and safety glasses when handling chemicals and blowing off chemicals with compressed air.
I'm wondering about adjustment. What are the white & red plastic things for? The manual says to take it to a service center for adjustment with the symptoms my trimmer has. My best guess is that they set the hi & lo at the factory & put those plastic things over top to keep it that way. I got the trimmer from my aunt who said it's barely been used, but they bought it 6-7 years ago. Since I found dirt in the screen, maybe it just needs a cleanout? Is that more likely than needing adjustment?
Good work. You present the information well. You don't speak to fast and you sound good. Do you have any e-books available going into detail about the how and why of your trade?
Hey sorry, I have a trimmer incorporating a carburetor equal to samples, the problem is that when you turn off the engine accelerated, alludes me want to keep it stable.
I got something similar. 33cc 2 stroke scooter engine someone put on a bike, I bought the mount and motor thye had setup. Engine was a pain to run on the fuel they left me in the rigged gas can. I did notice some junk in it and in the fuel lines. Some junk in the bulb. It runs like a beast till warm, carb dirty or spark?
Hi Mark, awesome video I followed the steps and actually ended rebuilding my carburetor. So I finally got to turn on, but it will stay on only with the choke engaged. When I give it gas, the choke disengages and engine will accelerate erratically and then shuts off. Any thoughts
I was having problems with my Ryobi CS26. I could start it & as soon as the choke goes off it stalls. Watched your video and decided to give it a try. Discovered my fuel filter had fallen off so ran to Home Depot and got fuel line replacement kit. Took carb apart, cleaned it and reassembled. Put in new spark plug. Put it back together and it starts (as it did before) but as soon as I pull throttle & release which turns the choke off, the engine stalls same as before. Frustrating! Any ideas?
I have a SST25 weed eater. It would start but stall as soon as I let the throttle all the way out. I tried to adjust the carb but it was not enough. So i tried this cleaning process. I used Brake Clean instead of carb cleaner because I didn't have any and they work the same in my experience. Now when I prime it, fills the bulb and then the bulb becomes hard to depress any more. It tried to start RIGHT after I cleaned it and now it won't even kick over a few times. I'm stuck. Did I ruin my carb?
I have a Troy Bilt string trimmer, It will only run with the choke at 1/2 if I open it all the way it bogs..... does this sound like a dirty carb? it's fairly new.
Thanks for sharing all the trick and technique. Is there a place to order a pump assembly for Troy Bilt 2200 PSI pressure washer? My output pipe is cracked so the water is leaking out like crazy, as the result I probably get about 50% pressure on the wand. Thanks. Tom
Hey, Am I seeing things? At 1:25 you separate the diaphragm and gasket from the cover. At first, it appears that the big round metal thingy is facing the lower cover plate. Then it appears not. Also, it appears that the gasket does not go against the lower cover plate. Later, when you reassemble, it appears that you put the gasket right next to the lower cover plate. Is that small circular metal thing a rivet? Whatever it is, does it go against the cover plate or does it face away.
Question: How come when you re-assembled the unit, at around 7:30 minutes into the video, you reversed the diaphragm and diaphragm gasket. When you disassembled it, the gasket was separating the carburetor and the diaphragm, but when you reassembled it, you swapped the 2, placing the diaphragm closest to the carburetor and then the gasket between the diaphragm and the outer cover? Is this an intentional "technique", or an error, or perhaps it doesn't matter much either way? Thanks -Lee
Does it matter if you flip flop the placement of the diaphragm? I noticed the butterfly metal of the thingy is facing you when you disassembled it but away from you when you put it back..
Around 5:18 in your video you clean the 'head' piece or the part of the carb where the primer bulb attaches and does it's work. I did the same procedure but now, the primer bulb will not perform it's function, and if I try and run the engine, the primer bulb will collapse. Is it possible there are one way valves inside some of those little holes, and spraying cleaner in the 'wrong' direction could cause one of those to become stuck? Where else should I look for fuel flow problems? Thanks!
Look People - the gasket was stuck to the cover plate on removal. This means it goes on just BEFORE the cover plate assembly, NOT before the diaphragm.
Do you have any videos or resources on removing the carburetor to start with. I just got a replacement from you guys, but can seem to remove the old one from the Ryobi Trimmer. I don't have traditional screw heads when you remove the air box cover. I have threaded rods with two nuts screwed on to them. I attempted to pry the filter box loose, but was afraid I would break it. Should I just apply more force? Is it supposed to pop off? Thanks!

The metal disc is part of the diaphragm. It is the part that makes contact with the metering lever. The metal disc should face down or toward the carburetor body. You are correct about the gasket. I'll admit it... I made a mistake. The diaphragm should be above the gasket. The proper reassembly order is, from carb body working out, gasket, diaphragm, cap. Sorry for the confusion.
-Mark
I have cleaned a lot of these with no results until I started removing the screen and cleaning under it. Makes all the difference in the world. Small engine mechanic tipped me off on this. Bend a pin and grab the side of the screen. Comes out easy if your lucky and no damage.
I am glad to see you mentioning the spring that loves to go flying. First time I took apart a dead carb to see what makes it tick that piece almost hit me in the face and I never found it in the garage again
As an added tip. . .I've found that I can use a thin sewing needle to physically go into the orifices and clean out any gunk that's been built up. . mainly from ethanol treated gasoline (which is a bad idea to use in carburetors). Quite often carb cleaner simply won't clean out these orifices totally. I spent a LOT of time going through the pangs of trying to get string trimmers and later, chain saws , running until I was schooled on the problems with ethanol additives. It's a major hassle. If you can get 100% gasoline, it's highly recommended that you use it in your 2 and 4 cycle engines. There's a class action lawsuit involving small engine builders against this gas. Unfortunately, it's often the only thing available. Nice video. Well stated.
One thing I would additionally recommend is that you protect yourself from contact with the carb cleaner and, in fact, all similar chemical. They will have a cumulative negative impact on all bodily systems especially the kidneys, liver and nervous system. Moreover, they could possibly be carcinogenic and, like many carcinogens, the resulting cancer might not appear until decades later.

thanks for taking the time to help us folk who havent stripped a carb before,my lawn is back to normal, from down here in west wales uk
Thank you! Had a Stihl FS 55R that wasn't working... came across this... demystified the process for me, and 30 minutes later it's running like new. Thanks again!
A very well presented video but, I have went through this cleaning procedure and sometimes it just doesn't work. I even tried soaking the carb in carburetor cleaner for days. Didn't work. What finally did was taking a tip from a long time small engine mechanic
Basically, after removing all rubber parts, you boil the carburetor in a strong solution of Tide detergent. Apparently, varnish can be so tough and plentiful that a little spraying or even soaking in carb cleaner just won't do any good. I even tried going through the portals with guitar wire as was suggested by one mechanic.
When I got through boiling one carb that I was having problems with, after trying everything in this video and more, I ended up with a skim of something on top of the water which I took to be more varnish. Once put back on the engine, it ran like a top.
dnsmithnc Thank you for the advice and feedback! Always great to hear about people's repair experiences.
thank you. how strong of a solution?
***** Justin, I just can't tell you exactly as I didn't take note of how much I put in. Maybe a couple of tablespoons, (not soup spoons) for a 1 1/2 quart pot. I can say that you need to have the Tide thoroughly dissolved before putting in the part. Also, make sure rubber or gasket parts are taken off. In addition, make sure the carburetor is thoroughly rinsed off after removing. The best way is transfer the carburetor to clean hot water, boil it for a for a minute or two then thoroughly rinse off with cool water as soon as you can. You want to make sure you don't leave any detergent in the carburetor as it will stop up the ports/passageways as well. Good luck.

So helpful, thought with a Roybi trimmer for a weekend. Cleaning worked great!

Hey mark I work at a lawn mower parts store and I came to realize that for the rhino carburetors the Zama carburetor kits with part number Gnd-12 or Gnd-18 have worked for my customers. Try it!
I found that using a 12 gauge plain (not wound) guitar string will work cleaning the tiny holes..any gummy stuff in there away.
Thanks this helped me fix a badly running chainsaw (clogged spark arrester screen) and a non starting strimmer. (new spark plug) clear and methodical instructions. Nice.

Excellent video and instructions,very clear and easy way to get it right,and if one cannot follow this simple instructions,perhaps shouldn't touch the carb.
I love your videos. PLEASE keep them coming. May I ask why the adjusting screws (Hi and Low) were not also cleaned?

Thanks for posting this! I happen to have a Ryobi weed trimmer as well, so this video works perfectly for me.

AWESOME!!!!! Thank you so much for this video! I just cleaned my first 2 stroke carburetor ....... SUCCESSFULLY!!!! :)
Great video and well explained but failed to show checking and clean needle and arm level for correct fuel intake
I noticed that the high and low needles weren't removed for this cleaning. Isn't that required for a thorough cleaning?
I believe that carb cleaner contains MEK which is highly carcinogenic, rapidly absorbed through the skin and is associated with liver cancer (hepatocellular carcinoma) with long term or repeated exposure.
Outstanding video! Thanks for the effort. It is very helpful!
All your videos are very well done. Thank you.
Excellant tutorial !
Thank you Mark, I look forward to more videos.

Great video helped a lot but you might want to press the use of safety glasses when using carb cleaner it burns like hell when you get as much as the mist in your eyes so guys and gals use safety glasses again great video thanks my unit runs great.
Mark, great job on the rebuild video!
Thank you for the video. You instructions were clean and the video was good.
Thanks for this. I've got a Sears bushwacker with stalling problems. I bet this will fix it.
Great vid thanks, I need to get 2 of these Ryobi carbs done this afternoon.
@Mr70Cenzo Great suggestion. I have a box on my bench but it seems that in the heat of the repair I never remember to put them on!

Beautifully presented. Thank you. I wonder if it's possible to simply use the cleaner straight in the the fuel lines, without pulling it apart?
Thank you so much for the good videos 😎

you might want to put a little call-out on the video at about 7:33 to bring attention to this error, as some people may not read the comments.
Thanks for sharing - I'm now thinking it's worth a noob like attempting before buying a new one. Cheers
Thank you for sharing. Made me nervous watching you spray carburetor cleaner without safety glasses.
Ryobi may not offer a rebuild kit for the carburetor, but the carb is probably made by Walbro (or some other carb mfg.), not Ryobi. Usually, the carb mfg. & model can be found on the carb body, which will allow for the proper rebuilt kit to be obtained.

Hey Mark, I just followed this video and got my Ryobi running again--but now it will only run at full choke, and it runs at full RPM. Any ideas for me?
At 7:29 ... It's my understanding it should be gasket first then diaphragm.
I have been running 100low lead aviation gas in my 2 strokes for years.. Never a problem if carbs are clean to start w/ and proper maint is maintained.
The carb will need to be cleaned internally like shown in the video. A good cleaning should have you up and running again.
-Mark
I'll be doing this over the weekend! My ryobi CS30 will only run after being primed... as soon as I give it throttle, it will bog down and run slower and slower and die.
This guy is a genius...thanks

you need to adjust your carb while it's running, rev it out and adjust the carb screw should work : )

on the inlet where the gas line connects to the carby, just shoot some compressed air into it and the little screen will come out. then just push it back in when it is clean. also, carburator cleaner can ruin the pieces as i have found out the hard way
Maximum Power Equipment had several kits in stock
Excellent video...Thanks Mark...take care.
Wear safety glasses too. My eyes are still sore from carb cleaner that shot back from a carb body orifice.
To be safe, could you put the unit in a Ziplock bag when removing and replacing the needle assembly? Or loosely wrap it in plastic wrap. That way, you could see what you are doing but if the spring got loose, it wouldn't fly across the room.
FYI...Wear your PPE's when doing instruction videos. Just in case, your PPE's are your Personal Protective Equipment such as nitrile gloves and safety glasses when handling chemicals and blowing off chemicals with compressed air.
Beautiful, nice job., very professional. Thanks
I'm wondering about adjustment. What are the white & red plastic things for? The manual says to take it to a service center for adjustment with the symptoms my trimmer has. My best guess is that they set the hi & lo at the factory & put those plastic things over top to keep it that way. I got the trimmer from my aunt who said it's barely been used, but they bought it 6-7 years ago. Since I found dirt in the screen, maybe it just needs a cleanout? Is that more likely than needing adjustment?
Good job. Good video.
Good work. You present the information well. You don't speak to fast and you sound good.
Do you have any e-books available going into detail about the how and why of your trade?
Hey sorry, I have a trimmer incorporating a carburetor equal to samples, the problem is that when you turn off the engine accelerated, alludes me want to keep it stable.
I got something similar.
33cc 2 stroke scooter engine someone put on a bike, I bought the mount and motor thye had setup.
Engine was a pain to run on the fuel they left me in the rigged gas can. I did notice some junk in it and in the fuel lines. Some junk in the bulb.
It runs like a beast till warm, carb dirty or spark?
Did you reconnect the fuel lines to the right inlets? Try swapping them around!
Thanks brother for this video
Hi Mark, awesome video I followed the steps and actually ended rebuilding my carburetor. So I finally got to turn on, but it will stay on only with the choke engaged. When I give it gas, the choke disengages and engine will accelerate erratically and then shuts off. Any thoughts
I was having problems with my Ryobi CS26. I could start it & as soon as the choke goes off it stalls. Watched your video and decided to give it a try. Discovered my fuel filter had fallen off so ran to Home Depot and got fuel line replacement kit. Took carb apart, cleaned it and reassembled. Put in new spark plug. Put it back together and it starts (as it did before) but as soon as I pull throttle & release which turns the choke off, the engine stalls same as before. Frustrating! Any ideas?
I have a SST25 weed eater.
It would start but stall as soon as I let the throttle all the way out. I tried to adjust the carb but it was not enough.
So i tried this cleaning process.
I used Brake Clean instead of carb cleaner because I didn't have any and they work the same in my experience.
Now when I prime it, fills the bulb and then the bulb becomes hard to depress any more.
It tried to start RIGHT after I cleaned it and now it won't even kick over a few times.
I'm stuck.
Did I ruin my carb?
I have a Troy Bilt string trimmer, It will only run with the choke at 1/2 if I open it all the way it bogs..... does this sound like a dirty carb? it's fairly new.
Thanks for sharing all the trick and technique. Is there a place to order a pump assembly for Troy Bilt 2200 PSI pressure washer? My output pipe is cracked so the water is leaking out like crazy, as the result I probably get about 50% pressure on the wand. Thanks. Tom
Hey, Am I seeing things? At 1:25 you separate the diaphragm and gasket from the cover. At first, it appears that the big round metal thingy is facing the lower cover plate. Then it appears not. Also, it appears that the gasket does not go against the lower cover plate. Later, when you reassemble, it appears that you put the gasket right next to the lower cover plate. Is that small circular metal thing a rivet? Whatever it is, does it go against the cover plate or does it face away.
Question: How come when you re-assembled the unit, at around 7:30 minutes into the video, you reversed the diaphragm and diaphragm gasket. When you disassembled it, the gasket was separating the carburetor and the diaphragm, but when you reassembled it, you swapped the 2, placing the diaphragm closest to the carburetor and then the gasket between the diaphragm and the outer cover?
Is this an intentional "technique", or an error, or perhaps it doesn't matter much either way?
Thanks

On some carbs gasket is underneath, on others it's on top of diaphragm, depends on make model year etc.
Is it possible that if you put the gasket and the Diaphragm on backwards, you can have throttle issues?
Does it matter if you flip flop the placement of the diaphragm? I noticed the butterfly metal of the thingy is facing you when you disassembled it but away from you when you put it back..
can we get a carb from a different lawn mower and put it into another one? or can we get a lawn mover carb and put it into a pocket bike
Around 5:18 in your video you clean the 'head' piece or the part of the carb where the primer bulb attaches and does it's work. I did the same procedure but now, the primer bulb will not perform it's function, and if I try and run the engine, the primer bulb will collapse. Is it possible there are one way valves inside some of those little holes, and spraying cleaner in the 'wrong' direction could cause one of those to become stuck? Where else should I look for fuel flow problems? Thanks!
i wish somebody had a video on how to make a homelite bv26b blower run !..or just a video on how to repair one!
Hi, I have a older craftsman chainsaw. I installed new carb and fuel line and filter but getting no fuel to carb. Thanks.
Look People - the gasket was stuck to the cover plate on removal. This means it goes on just BEFORE the cover plate assembly, NOT before the diaphragm.
Do you have any videos or resources on removing the carburetor to start with. I just got a replacement from you guys, but can seem to remove the old one from the Ryobi Trimmer. I don't have traditional screw heads when you remove the air box cover. I have threaded rods with two nuts screwed on to them. I attempted to pry the filter box loose, but was afraid I would break it. Should I just apply more force? Is it supposed to pop off? Thanks!
thanks for the information, Buddy. I'll just buy a new, Carb..
