Thanks for this. I used my drill bits and extracting tool , which i hadnt used in years, to get the 3 bolts out from my carb earlier today. Beats needing to buy a new carb. Now to get replacement bolts with actual heads to them.
Hey sir, my taotao 50 wasn't running, just cranks and cranks but no start. Watched your vid, did your tricks, cleaned the jets (with a blowtorch), then reassembled. Went to fire it up and it just cranked and cranked, I was a little bummed especially after seeing the idle jet was clogged, I thought for sure I found the issue. After a few more tries it fired right up to my amaze! Thank you for this great vid and i learned a ton! Thanks again! You're awesome!
I have a scooter I got for free. It wasn’t running and would not turn over. These videos helped out a bunch I getting it going. I cleaned the carb the same way and I used throttle body cleaner which worked for most of it. The jet was so clogged I couldn’t see through it and could not get a wire through it. What I did was I used torch just like the video then ran some speaker wire to clear it out. You will see a little and I mean tiny puff of smoke when you use the torch method. I didn’t hold the flame up longer than 4-5 seconds and it burned the fuel that turned to lacquer out. BTW I held the jet with some needle nose pliers. Great video!!!
I watch many Coborator videos but must say this is the Best Explained, very simple but straight forward, lol he even explained why the scooter was running in the Back gorund # A+ in My Book #Honor roll
Hello! I have a Buddy 50 cc scooter. It runs great except for sometimes it hesitates a little in the sense that it will turn off at strange times when I am going lower speeds or it will not turn on.. In order to get it to turn on I carry a little screw driver and carb cleaner and I will take off the air filter cover and spray the intake with carb cleaner and put it back on. Then I go to start and it starts VERY good. It was just brought to a shop who charge like $200+ for a carburetor cleaning and spark plug replacement. The shop is called Boca Scooters… I am NOT convinced that they did honest work but I don’t know know for sure. I would like to have it turn on normally. (without having to have to spray the carb cleaner every time) I believe that I need to work on the carburetor again or get replaced altogether OR get a valve adjustment. I would like to bring it to a different shop but I don’t know really where to start. Gas is clean, premium used (50CC 2018 Buddy) Carb JUST got cleaned but NOT positive they did honest work…….. Spark plug all new. Where should I start from here?
Hey Matt great video just so you are aware the location that would have the Air fuel adj screw that's is just a brass cap drill it out and the screws underneath
Hi Matt. Love your videos! I need some advice, Im thinking about buying my friend's 2015 taotao 50cc which hasn't started since last fall. I don't have much experience, do you think I have a shot at fixing it up or is it a bad investment? Thanks!
I need to change my carburetor tray. If I remove the carburetor, not moving the adjustment screws will it throw the carburetor out of control.Thks for your video 😊
This may work, myself having dealt with many break off screws I use a dermal grinder to make centre of screw then a 1/16 to 1/8 left hand thread bit and just back out screws.
couldn't get scooter to start, did everything from valve adjustment to replacing fuel/ vacuum lines. turns out pilot jet was clogged. now it runs like new!
Trying to do a main jet on my stock carburetor. 2020 Taotao pony 49cc Same bowl cut off screws also pieces need drilling also. Thinking of just getting a new carb upgrade. But, there's alot of fakes going around. Back to playing with the stock one abit more. I.g.
I did the same but after first small hole drilled, I just hammered in old hex bit and unscrewed it and it even resulted in being able to reuse old screws
I put a pod filter on and a new carburetor put a 110 main jet in and it takes about 4 tries to start then it runs good trying to figure out if i need a bigger jet
I've been watching you for a while and you know your stuff. Bro I just put a new carburetor on my Chinese scooter and removed the egr/pair system and now when I tried to start it it won't stay running. Please tell me what to do. I have a mentally ill brother and a elderly mom to take care of and this scooter is my only transportation. Please tell me what I need to do. Please help
Where the air fuel screw should be on the side of the carburetor where that plug is you can drill that plug out in the screws underneath it I just did it on mine
Matt, I have a tao tao quantum 150 with a 61 mm big bore kit and your retro exhaust plus a uni air filter running the stock carb. I ride it in West Virginia, how much bigger jet should i need to get it tuned right?
How do you make these chinese scooters run for the longest time possible? I watched a video and they said Premium gas and changing oil every 500 miles.
I don't think mine has the tamper-proof screws...that is a good way to fix that problem...another thing I want to say is there's another guy that did a video on that air adjustment... that's just a plug ...drill that plug out and you can get to the air adjustment screw
I just purchased a Znen 150cc GT and it will start but then when it gets some gas, it stops running. I have to keep starting it. Any suggestions? Battery is good. just changed the fuse when it didn't need it. drilled a hole in the gas cap like someone suggested. It only has 32 miles on it.
Hate to be the one to tell you this buddy, but... Much like a car, just idling your scoot isn't going to charge the battery. You have to actually RIDE it. FYI...you can also drill out that plug over the mixture adjustment screw too.
Hay man I dig your channel and your content whatever that means to the only thing is you do seem kind of preoccupied with videotaping have you ever considered having somebody video tape (run camcorder shoot video and all that crap) and why would you have a person to run the camera for you and take a big part of the taping? So? you can and can concentrate on telling somebody how to clean the carburetor second nature to you but you're pretty occupied with the video part of it you need a video crew here sound Smith after and remember.. your the face of of the out for and that sir makes you the man on the the scene kind of a Bill Nye the science Guy of scooter world
I got a linhai 4 wheel same carb. I got it to start and it idles just fine. I can even rev it up for like the first 30 second to a 1 min after start up. After that if I try to rev it, it boggs out and dies. I've checked for vacuum leaks, cleaned jets and even checked to floats, this a brand new carb. I tried letting it run till it warmed up, think it was just cold natured. Even after idling for 30 mins and its nice and warm its still boggs out and dies if it touch the gas. Got any idea? maybe a bigger main jet? I just don't know.
Rolling Wrench where is the vacuum end of the fuel valve located? Is it on the carb or on the bike. And is the fuel diaphragm the big diaphragm in the carb under the metal cover on top of the carb?
Sounds like your main jet isn’t the right size should have two jets an idle jet and a main jet for when it’s actually driving or pulling however you call it I would check the main jet
Matt, I own a tao tao future champion. It has a 100cc big bore kit. I installed a 26mm 150cc carb. It runs like shit. What jets should I be running? It has a 105main jet but will not idle at allllll
What size big bore kit? If you bought it on eBay a lot of time people call a 50mm kit a 100 cc the is actually a 75cc the 52mm is a 90cc. Here in Colorado there is no possible way to run a150 carb on either kit due to our altitude mile above sea level. I would recommend installing the stock carburetor and re-jetting it to the kit. In Colorado the stock carburetor without being rejected works perfect for the 90 cc kit. However I have heard of some people at sea level running a 150cc carburetor on the 90cc kit and seeing big gains. I have no experience at I sea level . I hope this helps.
I'm up in pa I had the 51mm BBK and I was running a 24mm 150cc carb a9 cam,pod filter and free flow muffler and it ran perfect since your on a smaller BBK I'd kick down your jet maybe 100 unless your still on stock muffler,intake so on just my opinion tho
Rspec Nick I have free flowmuffler n pod filter . Stock cam. Using 26mm 150cc gy6 carb. It has 105 main jet. I’ll go down to a 100. Km not sure what pilot jet it has
Yea try kicking that jetting down a little and you should be good even on my 171cc that has a 28mm koso d slide and that's more then enough for a 171cc if that kinda puts the sizing in a good perspective
to center a drill u will NEED to punch a hole.. if u can simply take a screw/nail and a hammer to make a little small dent to put ur drill for it to follow if u dont have a center punch. just need a simple tap or two.. but pls use it so ur drill doesnt wander...and u wont have to use ur fingers trying to center the fking drill bit.
If you bothered by such, end the EPA! You wronging the manufacturers for trouble they never wished to cause you - thy lose money to these extra production steps too. It is the EPA and its like that are causing all this as they rule that you are not to serve or adjust your own carb anymore. A set of broken screw extractors usually fix that issue. Center punch the broke off head, drill, and then punch the extractor in. With such crusty internals it always better to completed disassemble the carburetor, which is also need with carb cleaner, that will eat your seals and diaphragms otherwise! Seriously, carb cleaner kills seals and diaphragms!! Use a fitting ring spanner when removing the main jet the counter and then remove the needle section of the jet, it got fine fuel ports too. Rather then to heat any brass jet, soak it in carb cleaner for some time. Heating the brass jets will soften them up to be then eroded away by the fuel stream or the fall apart midway at some point from vibrations. So if you do use heat on the jets, be prepared to buy and replace then with new jets as soon as possible.
I have a 200cc go cart and removed my old air filter box which had two hoses that ran to the old air box from the crank case where the belt is and from the valve cover where the valves or piston is. which both have vacuum but when I put an aftermarket filter on what do I do with those hoses that have vacuum.my cart is like this one in the link. I’m not to familiar with small motors maxoffroad.com/product/200cc-4-seat-spyder-go-kart/
Hate to tell you this but it has nothing to do chinese manufacturers has more to do EPA = Environmental Protection Agency and Carb = California Air Resources Board keep in mind even lawn mower, weed eater and many other power tool have same problem and anything with engine will also have same problem to
That’s not a taotao dude and it’s a standard Cvk carb and they have snap off heads btw that’s not called fuel screw it’s a low speed idle mixture adjustment screw seriously dude?? You can buy a new carb on amazon currently for $18 total

If you use a left hand drill bit it often will catch the bolt and unscrew it in one operation. Thanks for the vid.

Got my scooter running! Any tips on adjusting the jets so it doesn’t die when idle or revving?

Thanks for watching. I appreciate the support 🙏
Trying to do a main jet on my stock carburetor. 2020 Taotao pony 49cc
Same bowl cut off screws also pieces need drilling also. Thinking of just getting a new carb upgrade. But, there's alot of fakes going around. Back to playing with the stock one abit more. I.g.
I did the same but after first small hole drilled, I just hammered in old hex bit and unscrewed it and it even resulted in being able to reuse old screws
happen to know the thread size on the float bowl screws by any chance?
What size are those 3 float bowl screws?
I know this is from way back in January, but any chance you can do a vid on putting the whole carb back in?
I put a pod filter on and a new carburetor put a 110 main jet in and it takes about 4 tries to start then it runs good trying to figure out if i need a bigger jet
I've been watching you for a while and you know your stuff.

I have a mentally ill brother and a elderly mom to take care of and this scooter is my only transportation. Please tell me what I need to do. Please help
Whats the float height on the carb because the carb body has an angle, do you set the float height at the angle or keep it straight
Where the air fuel screw should be on the side of the carburetor where that plug is you can drill that plug out in the screws underneath it I just did it on mine
I should have mentioned two out of three taotao carburetors don’t have anything to adjust if you still the plug out.
Rolling Wrench yeah I drilled out the plug on mine and had the air fuel screw underneath it so I was able to turn it in very nice
can i put 2t carburetor on 4t scooter? will it be better? i am putting 82cc cilinder kit.
Maybe? I haven’t tried. It should work
Hack saw it and make it a flat screwdriver groove.
What thread are the new screws?
Matt, I have a tao tao quantum 150 with a 61 mm big bore kit and your retro exhaust plus a uni air filter running the stock carb. I ride it in West Virginia, how much bigger jet should i need to get it tuned right?
I would start with 3 sizes bigger on the main jet, keep the stock pilot jet unless it backfires at decel, than go one size bigger. Start there.
Is the 150powersport taotao also has a carb?
How do you make these chinese scooters run for the longest time possible? I watched a video and they said Premium gas and changing oil every 500 miles.
I don't think mine has the tamper-proof screws...that is a good way to fix that problem...another thing I want to say is there's another guy that did a video on that air adjustment... that's just a plug ...drill that plug out and you can get to the air adjustment screw
i saw a video to tap a notch on the corner with a wood screw then with the same screw and hole bink it counterclockwise save threads 2
I just purchased a Znen 150cc GT and it will start but then when it gets some gas, it stops running. I have to keep starting it. Any suggestions? Battery is good. just changed the fuse when it didn't need it. drilled a hole in the gas cap like someone suggested. It only has 32 miles on it.
It sounds like it needs a carburetor clean. Even know it only has 32 miles, it’s not unheard of.
what size are the new screws?
Awesome video
What size screws?
Which carb is this Chinese carb a copy of?
Hate to be the one to tell you this buddy, but...
Much like a car, just idling your scoot isn't going to charge the battery. You have to actually RIDE it.

Check to be sure the vacuum end of the fuel valve isn’t sucking fuel. Bad fuel filter diaphragm.
Rolling Wrench where is the vacuum end of the fuel valve located? Is it on the carb or on the bike. And is the fuel diaphragm the big diaphragm in the carb under the metal cover on top of the carb?
Did you make it run better?
