this guy is great he speek's simple shows you easy steps to fix your problem.
Thanks Kasey Young, I am having the same CDI box problem on my 150cc scooter. You will reap what you are sowing !knowledge here is repairing your on scooter.
thank you for making this video. I went to a scooter repair shop and the assholes tried to make me pay 300$ for a gas tank that I didn't need. They said my gas tank was rusted. My scooter was doing the same thing yours is doing. I bought a CDI box and put it on just like you showed here and my scooter fired up. Thank you for saving me 300$ for a gas tank I didn't need and 300$ for labor. This video was very helpful to me. You are appreciated.
Glad I could help. I've learned a lot on RUclips and am always happy to post a video to help others!!!
Kasey Young you the real mvp
Gas tank is plastic, so no rust

Finally a video that makes sense :)
Thank you man really helpful, easy to understand,simple,thats all that i need good job.🖒
Bro. 8 year old video saved my 2019 scooter with only 458 miles on it… hard time starting. I changed spark plug, cleaned carb, changed fuel filter and fuel. New battery. I was about to give up and saw the video. Paid $8 for CDI box and she started up… wow. Thank you
That was easy! Sometimes it can also be the stator/ pickup assambly or the ignition coil. Before changing them you should check all connections by unplugging and reconnecting them.
Thank you for your video and explanation of the Chinese scooter startup problem with regard to the spark plug and CDI box. I like the way you offer that kind of a clear and simple explanation of an issue without complicating matters. I have seen many videos about the CDI box replacement, but this is the first time to see someone provide a clear photo where it is located, how its parts (hooks ups) looks like, and how it can be replaced without any complication. I wish that you could also explain for us how to replace the ignition coil and carburetor on a Chinese scooter as well as the other issues that cause problems for many of us such as how to set up the gas and fuel lines and eliminate many of the vacuum hoses that cause unnecessary leaks.
Almost a million views! Great video, thank you. My next door neighbor gave me a WangYe WY50QT-55 that will not run. Got a feeling this is the issue.
Worked like a charm and saved myself lots of money. thank you so much for the video!
I have a 49cc Santini San Remo with a GY6 engine block, and by the look of things it's very similar to your block.
The carb and ignition coil look identical.
I took all the panels off, the seat, everything and for the life of me I couldn't find the damned sparkplug anywhere!!
Not one picture on the net was able to show the location of the thing. Thanks to your video I think I can find it now.
I know where the CDI is, and thank goodness that's easy to replace if I need to.
In the 80's I used to have all kinds of mopeds (Honda, Peugeot, Yamaha and Puch) and never had a problem with them.
But this silly little scooter is nothing but trouble!
thank you so much! my Chinese scooter is doing the same exact thing. going to try this out tomorrow when i have some free time.
you had the best and knowledgeable video! no BS funny stuff, just great information. couldn't find where the spark plug was, now I know, so I can check. thanks so much for all your good,info.
Awesome video! Thanks for making a clear and to-the-point tutorial. I'll try this on my Zongshen.
Pretty good video. Simple, easy to understand, just great remedy.
THANKS FOR THE UPLOAD SIR.
WISHING YOU WELL
JOHN
first vid i have seen that shows were that fuel adjustment is located , iam not familiar with Chinese bikes but this saved me a ton of work on a family members tao tao 50cc
New sparkplug and new CDI, it works! Thank youuu
Now I know how to fix the start problem. Thank you very much for your video...:)
Thank you! I was worried I would have to hire a mechanic. I am going to try this on my 150cc scooter, and if that doesn't work, THEN I'll spring for the mechanic... I will update you :).
How did it go?

Great work Kasey Young thank you for sharing this video with the RUclips community
Really Nice Job on the Video!
If you find another scooter with a carb problem post it I want to see the whole process. Good video!
Thanks for the nice video! Very good camera shot to clearly see what your doing.
hi Kasey, thanks a lot . Do one need to touch spark plug to metal bar in order to ground before checking the ignition? Also did you have a chance to experience performance cdi s. do they contribute to top speed and acceleration considerably?
In 2023 this is helping me. Cheers big man ❤
I love this video, I'll proceed the same with mine, um, not really sure if the carburetor throttle slide is faulty or the cdi box, either way, will be following the same steps for tomorrow
Great video, helped a lot! for once there is a mechanic video where the person talks clearly and the video is good. My Taotao had the same problem thank you!
Great jobb! You were metodic and take it slow.
Easy to understand! Thanks Stefan Forsberg
Sweden ✨👍🤠
Thanks for doing this video it helped me alot, this morning I went out to start my 50cc scooter it did not start my battery ended up dieing out right now I have it on the charger ! Two days ago I did change out my fuel filter and fuel line also had changed out spark plug after doing this two days ago I wanted to see if my scooter would start after cranking it over some times it fired up so I cleaned up everything thought I was all set for my ride today to my medical appointment dang scooter did not start after watching this video I will go out to check on the things you recommended on this here video I'll give another update soon after I complete these steps ok !👌
Casey you are a pro:)! You gave a tutorial on how to get your scooter back on the road,when you have no spark,by the way ,when gourds is not the issue you should go to the stator ,right:)?:) thAnk you for the tip
Thank you Kasey Young great job really helpful and easy to understand video
I was riding down the road & for some reason I drop power. I was able to kick start it & it went another 1/4 mile & it died again. When I opened it up I tried starting it again but I got this "Clanking noise" then it would just hum. Now it only Clanks like twice & nothing. I adj the Valves so that's not it. It getting gas threw the filter but don't know if it's the starter or the Carb. As I'm thinking about it, I don't think the break light comes on either. What do you think is wrong?
Wow thanks man I'm going to purchase my new CDI box and go riding thanks
Excellent video. Very clear.
I like how you mount the camera so you can use both hands Make it much easier to see what your doing
What should i do if i'm not getting gas on my finger? Fuel/vac lines are clear. I think i need to either replace the carb or clean it out. Do you know of a good tutorial for taking the carb apart? I tried spraying carb cleaner into the holes but it still didn't help.
disconnect the fuel line from the carb, and crank it over...fuel should only come out when the starter is turning the engine over or running the engine.
+James Turner also check to make sure your intake is tight or not cracked
Thank you very much your video was very helpful and easy to fallow
I have changed out the cod box I have good spark but still won't turn over. Is there something that I have or am overloading
Hi thanks for that. I have several Fosti scooters all hard to start,if they start at all, changed Cti ,carbs, plugs, even stripped one down put new rings and re seat valves. Spent days on them, have a top bike mechanic give up. They are new 2013, been sitting awhile, changed fuel, one did 120kms before packing up. Would appreciate any ideas Rod
My burgman 400 2004 was starting later when I tried it wouldn't. Brought the bike from a friend n it had been sitting for 3yrs... Put fresh gas in but didn't change spark plug... Would that b an issue it won't turn over (start)
Great video. And if all this doesn't fix my scooter....Hulk smash
hey brother i got a question, just bought a 88 riva jog, yamaha put a new battery in it put still no powe at all. no lights, dash lights or brake light. was sitting in trailer for 3 years. has new ignition according to previous owner..
Thanks for the video my scooter friends, great information ,keep up the great work everyone ☆☆☆☆☆☆☆
Great Video Kasey. (I've worked on GY6 50 & 150 scooters (EVO 150 is my current one/see my pic) for over 10 years and I have found that about 90% of Starting problems are the CDI boxes (even aftermarket ones die).
But I have a friends 2016 Taotao 50 that I've worked on a couple of times, but now it won't start. It's got spark, tanks got fuel, filter is clean, no lines are pinched, but it's not getting fuel.
Whats your thought ? the vacuum/petcock diaphragm is bad so no fuel is getting to carb ? or do think it might be a clogged jet in the float bowl ? or maybe a float that is stuck shut ?
NOTE: the plug was dry...even a little orange rusty, but I wired brush cleaned it and it still sparks ( I did replaced it though).
my next step was to take the air box off and spray some starting fluid in the carb and see if it will fire...which if it does, would tell me it's definitely a fuel flow problem.
My next step would be to pop the vacuum line off and the fuel line to the carb from the vacuum/petock and suck on the vacuum line to see if the diaphragm is working and letting fuel flow.
After that the only thing I can think to do is to pull the carb and clean it...which is a hassle, but I've done it before (on the Jonway Fone 150cc I used to have) so its doable, just a pain.
I would appreciate your thoughts.
You are a beast thx bro you fixed my scooter
Hey do you know where i can get my brake light assemly?? I have a moped just like yours.
Do you have a video about cleaning/replacing the carburetor on this same scooter?
I have to try that. Thanks a lot for the tutorial. 👍
You might mention your 5/8" socket for the plug = a spark plug socket. I was using a regular socket, to no avail, when it occurred to me....a week later, maybe I need a specialized socket. I did. It worked.
Thanks. It did fix my scoot. Subscribing to your channel.
nice job, did it to mine, works fine, now the battery gone,but that's Cool just buy a new one, thanks
Thanks big homie saved me bread I’m install mine soon as it comes in.
I just got a 2008 sl50qt-7 is there any way to delete or find a diagram of how the fuel and vacuum lines goes to the charcoal canister
Hi Kacey, I have a Suzuki vs150. I have changed the battery and it was able to start using the start button. I was able to do this for about 4 times to start it before it drained my battery again. I was hard to start so i guess pressing the start button for so long the cause? The kick start took a couple of tries but starting with a kickstart is no problem. i was wondering if this could be the problem with mine? Thanks.
How did you figure it was the Cdi box I'm having the same problem no spark I change the coil spark plug it has fuel one day it will run then some times I will be running the it dies but just today absolutely no start and I check for spark and nothing help thanks
Very helpful thanks cool video
Kasey - I own a Baolima that I am sure has the same issue. However, when turning it over yesterday to try to get it started, I let the starter run for about 60 seconds. Now I don't get anything when I depress the started button. It won't turn over at all. I checked the fuse on top of the battery and it is good. changed it anyway to make sure. Still nothing. It starts fine when you kick start it. So I am left wondering if I did something to the starter? Or what else could have happened. I am trying to get back to the point where it at least cranks. Then I'll check the CDI box and spark on the plug.
I have the the same motor on a Italien moped, what’s the brand on your moped? (Not the motor)
Watching this, it feels like this is exactly my problem. Seller said they just changed the sparkplug so that should be fine. Maybe get a cdi-box then 8) Thanks!
Hi, good vid. I got 4 of the Baotian version. All of the chinese engines are actually old honda replica engines. So the engine it selfe is good mechanichly. The other stuff is so and so tho. I fugured out that the Cdi`s are slmost open for moist. If you dry it out it will normally work again. So the trick is to keep it dry:-). Use a ballone or plastic bag. Also the wiring for the votage regulator is badly isolated. Normally located behind the front shield. Again thnx for good vid:-)
My Baotian struggles to start and wont idle at first. Once running for a bit it idles ok but if turned off it struggles to start again. Changed spark plug,Ht lead, auto choke, air filter, fuel filter and still same. Am i right in thinking i need to change CDI aswell? Anyone elses sorted after changing cdi? Thanks in advance.
isit a citibike2 ive got problems starting mine
Kasey I have been trying to get my scooter to stay running did some tests fuel filter and carb check and now replacing plug wire and box wont stay running any other ideas?
Good for you also hard starting is valve adjustment they could be too tight or too loose
I need to know what size fuse to use what the apps on the fuse
Where does this hose om the cylinderhead goes to? Do I have to plug that in somewhere? I can't find anything about it
Nice video. Well explained. I have a 150cc that makes like a weird noise when I crank it, almost like a grinding noise but it starts right up and runs great. any idea on that noise when cranking? thanks.
hey man ive got a bike and i adjusted the carburator it was working perfectly. 2 days later it just breaks down in the middle of nowhere and doesnt start do you have any idea why that would happen?
hi the 2 grey tubes on the bike what are they one of mine has come off i havent got the bike apart yet to see which one but can i simoly reattach it
Thks four your exllente video I have a Peugeot v Clic 50cc 4stroke I order a new Cdi after I order I find the cdi I order is racing cdi what you think if and change four Maine is going to blow my fuse or is ok the new cdi is lucking same is 4/2 pins Thks
WOW!!! Thank you very much for your video.
Thanks for the video! I have a 50cc tao tao, problem starting when is cold. It will eventually start after like 20 seconds of cranking. What could that be? And thanks in advanced!
Need help with 150cc gy6 there's power but the it's not switching on with key , any pointers?
I replaced the starter and spark plug in my 2014 yao yao and still no start and was told if the brake light comes on when trying to start it that a safety has tripped out (to keep someone from hotwiring it?) A previous mechanic had tried starting it from the solenoid... and may have tripped it. Is there a way I can fix that?
So I jus bought a racing cdi box and mine sounds exactly like yours. So if I change the cdi box will it crank? Oan I bought a new ignition coil as well.
What tool and size of that you use to tighten the spark plug
I just got a peace scooter i put to much gas in it smh. It wouldnt start took ot to the shop warrenty still good and they said it was fixed. Got bout 5 miles fown the road and it happened again what u think could be wrong. The mechanic said i was not bad. He was confident it was fixed. What do you think could be wrong. Changed the spark plug it still had the china plug in it. Any ideas would help ease my mind.
Absolutly great info...thank you.

Can CDI box have anything to do with headlight no working ?
Hi, I have a neco one b 50cc scooter, was riding out maybe 3miles or so oil line came lose with the clip, I noticed quite quick as the power went downstraight away so I stopped reconnected the oil line. I went straight back home, but scooter kept overheating every 5mins. and cutting out.... By the 3rd time my battery was dead so I couldn't try restart. I got home , I topped up the oil, let the scooter sit for maybe 12 hours and charged the battery for 12 hours. Now its not starting. it turns over and its spitting small amount of white smoke and it sounds like its close to starting but it just wont.Do I need to check anything engine wise? to see if this disconnected oil did any damage? or possibly clean anything? Just wanna avoid taking to dealership.... for a pricey fix.Thanks in advance
i dont know but my Beta ark 65cc mallosi wont start can you tell me what to do i change and the spark but still wont start
