Very he

Very helpful
Same!
Y'alls videos are better then a legit Tech School's lessons
Ty for all the helpful information. Especially the part near the end when you mention revving quick, or long and stalling and how it needs to be more lean or rich depending on whether it bogs down on those types of revs.
no problem did you give us a subscribe?
WOW, the best instructive video about carbs so far , thx a lot man , greetings form Egypt
Glad it was helpful!
I'm just starting to work on my scooter.. i mostly have one of my friends to work on it, but after watching this video + your other videos i'm begining to feel confident.. two thumbs up 👍👍
I couldn’t believe I couldn’t find a single descent video on how to clean a carb on a Vespa. Thankfully came across this. THANK YOU
Glad it helped
Do exactly as he says and it will work. Cleaned my "Coolster F5" carb and it worked right away. Excellent teacher.
Glad it helped
Thank you for a brilliant tutorial, the step by step instructions were easy to follow, my scooter runs perfectly now 👍
Glad it helped
Great vid! That was exactly my problem, pilot jet clogged! Thanks for making and sharing.
yes sir!
Thanks a lot for making this tutorial. I am having some issues with my scooter and was not feeling very confident about tackling a carb clean but after watching you work, I Feel confident to give it a shot.
No problem.
Hi!!!
My dad (older and retired) has a 1995 Honda Helix and he has been trying to get it to run for months and wasn't successful.....until he watched your video and cleaned the carb. He said the scooter runs better than it ever has!! Thank you so much for your help!!
Very cool!
I don't have a compressed air pump, but I did work around it with a bicycle foot pump with one of the conical attachments for inflating pool toys. I put the attachment into one end of a short carb hose and put the other end onto the pilot jet. Then I was able to blow out the blockage.
ok
Just wanted to say thank you. I "Cleaned" my carb before watching your video. Still wouldn't run. Your example of cleaning the jet with a small wire (I used guitar string) saved me. It was plugged, and it would not run. Now it runs like a charm. Thanks for putting this out there. It really helped.
Glad to help
Base on my own scooter components replacement record file, I listing them as below: (1) scooter fuel tank use 18661KM (2) scooter spark plug cap use 3535KM (3) scooter fuel filter use 6668KM (4) only those fuel lines I never very detail to check to replace that before! If you have further suggestion, please make me know to fix my trouble here, thanks!
This was a great video. You did a great job of explaining things. You covered the two and a half turns on the idle screw. This was key. Thankyou my friend.
By the way, twiddling that screw back and forth a number of times seemed to resolve the idling problem. There must have been some crap caught up in there. Bad gas will do it.
your welcome
Good video, you covered a lot of things. I liked the way you went over how to un-cap the idle screw and adjust it. Thanks
thanks
Outstanding video ! Thank you much for posting, helped me fix my sons 50.
glad to hear!
Thank you for the excellent video! Now I have the confidence to tackle my GY6 carb for the 150cc engine :)
great!
Extremely informative, especially concerning the throttle screw drill out!! Thanks!!
Right! I just cleaned one and thought I was doomed
thanks!!! did you ever subscribe?
Great explanation on the teardown. I didnt realise that you could drill out that brass cap. Thanks a million!!
Glad to help
Thanks for this video. Preparing to clean my scooters carburetor this weekend. Seeing this really helps understand the procedure.
Glad it helped
What a GREAT video, one of the best and most informative I've watched!
Glad it was helpful!
VERY GOOD VIDEO WILL TRY IT OUT AS MY BIKE HAVE CARB ISSUES SPECIALLY COLD START IN THE MORNING
I watched a few videos mainly looking for info on the idle circuit and none of them dove into this type of detail. Thanks so much, fixing a scooter my brother bought. I'm sure he will be thanking you too. Thanks again!
Glad it was helpful!
what about it exactly are you asking?
I was just wondering how the circuit worked (inlets, outlets ect.) And it was covered in the video. Thanks
Bond the carb to the chassis. put swollen gaskets in oven @ 200° for @ 10min. or leave in direct sunlight for 20min.
just replace them
Amazing video....i cleaned everything & checked under the floater as well....clean that ho ho ho as well.....put back together & baam....like brand new....cost me 10$ instead of 80$ from a mechanic....thanks again....
Awesome that’s why we make these videos!
The best GY6 Scooter Carb
video I have ever seen.,!
Thank you soooooo much

Glad you liked it!

👍👌🙏
Thanks for the video. It is a great help. I have (2) 2007 Honda Elite 80 cc. Both scooters have less than 160 miles each. I watched this video and got 1 of them running today by following your advice. I will tackle the other carb tonight.
Pilot jet was clogged and I made sure all the passageways were clear with air comp...
Its time to part with them, just want to have them running great. Thanks Again
Glad it helped
by far the best tutorial on youtube
thanks we are releasing a new carb video right now
Perfect concise lots of detail thank you
Extremely informative thank you.
Thanks helps alot thought I had to buy new carb for my jonway 150cc
One of the best carb practical videos on YT for sure !
I've helped my self learning about carbs and carb components and how to clean it with this video, made a good over all clean
few months ago, today i wanted to ride my scooter after it's been sitting for a while and of course, it didn't fire at first. then i remembered you saying in this video about how cleaning the pilot jet is enough, i didn't have all the tools prepared only a wrong sized flat screw from a leatherman that actually broke and damaged my pilot jet head, a garabge screw driver that stripped one of the philips screws and carb spray, anyways cleaned it and managed to fire my engine back again right away ! !
thank you!
Dude great video. I have a GY6 150cc. I need to clean soon because its not starting. I will try to clean the carburetor to see if it fully starts up. This is so helpful.
Glad I could help
Excellent detail to specificity
I also, in addition to everything you did here and this was a wonderful explanation, I placed a brand new fuel filter on the fuel line. It was a shock to find green mold growing inside the filter I'd installed just a month ago. Man these things can be problematic. Never put anything but pure new gas in there, never.
thanks
Mate ur video is amazing was bout to call a professional then see this tryed it and working perfectly thanks so much
Glad it helped make sure you subscribe it helps
Thanks for the vid. I can't tell you how it saved me. That #35 jet was plugged on mine and it wouldn't idle. Thought it was clear, but nope. Did the wire trick and carb cleaner/air blast. All good now.
Glad it helped do us a favor and subscribe it helps us keep this up! let your friends know as well!
Very! nice job taking everyone through the carb clean.
Thank you
thank you
Great step by step teaching. Thanks!!

Instead of running your battery down or covering the air box with you hand to fill the float bowl, just pull the vacuum line off the intake manifold and suck in like your hitting a bong 4 or 5 times and the bowl will fill up. Put the vacuum line back on and the bike should fire instantly. Also, if your bike wont start after cleaning the carb check your valves (assuming you have already checked for spark). By the time the gy6 engines get to the 3,000-4,000 mile mark the valves will need to be adjusted. Set them to 0.004" Intake and Exhaust.

This video is excellent. Very well done.
Thank you!!!
Glad you liked it!
Thank you for a very informative and helpful video.
no thank you
thanks boss, I effortlessly got through the whole vid
awesome
@@Scooterswapshop heh.. time flies. I've got my own scooter repair shop now and enough customers to hire a few employees. Thank you, again.
Excellent video!
Very clear instructions my friend...
Thank you...👍🙏
You are welcome
Excellent tutorial ❤
great video this gives my enough confidence to do it myself
good to hear
Great job on this video! It is fantastic!
Thank you very much!
Amazing video! Thanks a lot
Great video! Cleaning out the pilot jet and the mixture jet circuit did the trick. Also, adjusting the mixture screw 2 turns helped the idle out so much. My scooter would start but only idle for a 5-7 seconds before dying. It had been sitting for 5 months over the winter. The scooter is a Lance PCH 125.
glad you got what ya needed!
Absolutely awesome video, thank you
Glad you enjoyed it!
thank you so much for the vid. this helps alot!!!
Glad it helped!
Great informative video man!🤘🏽🔥🔥🔥
Appreciate it!
Yipeee. I did it. The thing is working now.
congrats
that was extremely helpful....thanks a lot!
Glad it helped!
Thank you.. very nice and easy to understand.
You are welcome!
great content. Thank you.
Regarding float bowl gasket swelling at 23:36 mark. Try cleaning the gasket with soap and water (e.g. Windex) and rinse with cold water. Then treat the gasket with Prolong Super Protectant PSL60017. The gasket will usually return to its original shape. Treating with Prolong is an optional but recommended step.
or just replace it
Great video. I wish I saw this 3 hours ago.
thanks did you give us a subscribe?
Great video dude thanks .......
Nice work
Very helpful, thank you! My scooter's float somehow managed to get half full with fuel despite no visible holes and no drainage after removing.... hell of a thing.
Glad it helped
My little Baja adirt bike became hard to start, and wasn't running real good. After about a dozen times of taking it off, cleaning it every which way but loose, and no luck, I went to Amazon and bought a new one for $12. Put it on, and it started on the first pull, and ran like a champ.
Sorry to hear that
For the O-ring that expands, something else I saw on another video with an expanded cd drive rubber ring is put it in boiling water for a few minutes and that'll shrink it back down
YUP but cheaper in labor to replace
Best video on yt, thanks!
Wow, thanks!
Great video-- helped me a lot ---thanks
Glad to hear it!
Dang thanks! I'm about to start the project of reviving my mom's scooter so I really needed some info on carb cleaning... thanks again
yes sir
thanks a lot ,i did all off that ,but it wont run on iddle keeps wanting to die ,thanks for your help ,really appriciate
My SYM carburetor scooter over half year that engine does not working in Taiwan!
Due to my fuel tank located within under SYM scooter pedal, and I try to push scooter start motor switch and then I got some situations as below: (1) engine cylinder pressure is 126psi (2) spark plug has flash (3) fuel tank is not pushing gasoline through the fuel filter out? It seems my scooter fuel line system has block issue, could you offer some suggestions to help me fix my breakdown scooter here, thanks!
Fantastic video guys! Do wish you went into the diaphram part so I could see the exact order of assembly.
This is pretty in depth its self explanatory as you take it apart.
Ok I've been on here looking for all my scooter problems when they come up or needed for Up-Grades etc...This was the FIRST with a CABO 50 in them. Thank God I understood the video without double watching checking over etc. Cause its my bike lol. Thanks again brother any other videos for future reference??
Glad I could help!
Great work!
thanks
Thanks for the detailed info. I just bought my first moped off FB Marketplace 2019 with a rusted out gas tank. Wish me luck
Good luck! YOU Can do it
Great video, thanks!!!
Glad you liked it!
Do I need to drain my tank if I'm doing a carb cleaning. I live in the south so i use my scooter daily so it doesn't sit. Also first time about to try this.
Can I use a PZ20 instead of a PX19? It’s a 1997 xr70r stock engine but I can only afford one. I know there Chinese parts but it’s just a fun bike with the kids. I’ve had 3 CT70’s green, red and blue. Only one was a manual clutch and the smaller kids liked the automatic. I have had 3 z50’s. But anyways can you tell me which carb will work better please.
Bro thank you so much your a life savor
Happy to help
Twist ties with the paper burnt off, or strands from a wire brush work well for cleaning jets if you dont have a jet cleaning tool.
Tool is very affordable!
Fantastic mate thank you.
No problem 👍 make sure you like and subscribe!
Nice vid thanks
Great job w the video
thanks
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?
clean it your self and jet it properly
If I would wanted to upgrade can I use a 150cc instead of my 50cc or does it have to be 50cc
very imformative sir hope to solve my sym jet100 wth carburator problem...tnx again
glad its informative!
Great tutorial. Should the wire pass easily through the pilot jet or is it Ok if it sticks and need some persuasion?
Should the wire pass easily through the pilot jet.
You just made my bike run again 😂😂 thanks
Glad to hear it!
❤Thanks a lot !
Question, my 2020 49cc wolf islander with 3890.1 miles does not have the power to get from 0 to 40 like it used to, also I had to make it idle higher to keep it from shutting off after letting idle. Things I did to fix but did not work: changed spark plug, fuel filter, air filter, and valve adjustment. Valves were okay. The spark plug was wet oily looking after letting it sit for two days. I am thinking my carburetor might need cleaning or replacement. What is your professional opinion????? Thank you.
Someone please help and I thank you.
we dont mess with the chinese bikes just take it step by step
Verry informative. Could you make a video explanation on the needle and the diaphragm on top of the carb. Does it have to move, how much, how to be sure it's in good shape, etc...
BigPitter you can adjust mid range.. move needle up
we have a video on how to tune a carb goes over that
I just bought a metropolitan from an auction that has 1146 miles on it. Was missing air filter and a couple cracked plastics. It barley wanted to start and the fuel pump was clicking like crazy. I replaced the pump, added a stock filter and I believe I did a good job cleaning the carb and I also reset the ECU. Now it fires up in 2 or 3 kicks. Idles good and seems to run good on the stand but it bogs at about 1/3 throttle when the wheel is on the ground. Am I missing something or do I need to take another shot at cleaning my carb?
hard to say
I have a sym100, I cleaned out the carb, when cold it should sit a wile before it rev up. 2 stroke. I have one question... That hole in the float bowl where that tube from the choke fit in, Should it be open at the bottom of the bowl to the main compartment, or should it be blocked. If I look in the bowl, it looks as if there is a small brass part between the bowl and the chamber where the choke pipe fits in. But as I checked, it is closed. I am talking about that port that you first inserted at 25:34. Should it be open at the bottom or not connected to the main bowl??
nice
Piaggio typhoon 50cc. I drilled out little copper plug that looked like the one you drilled out but there was no screw under it, only 2 little holes. I think I screwed up my carburetor now.
Bravoo,bravoo....un video foarte bun :)
thanks!
Great video. Could a dirty carburetor be the issue if the vespa starts fine when cold but won't start when it's warmed up?
Could be
Nice job on the info and the production. I have gy6 lance soho 50cc running top performance for stock BUT the idle surges from about 1750 to 3100 if it sits after warm up. 20 seconds from hi to low idle Rev it to 5k on kickstand and release it ids slow to come to idle. HELP.
Sounds like you have a carb issue .
I just did a big bore kit on a 2021 Amigo Speedy 50 to 80, it still has the 50cc carb on it. It isn't getting fuel, so a good clean and adjustment is needed. Do I need to change to a larger carb if that doesn't work?
You need to tune the carb and jet it
@@Scooterswapshopwhat is a good jet kit for that application?
I tried to restore my bike Honda Lead 98 (2T). It kept running too rich especially in the morning. It ran for 2 days then couldnt get it to start. I am thinking of giving it another go, I wonder if I gonna need new parts. Very frustrating sometimes I just wanna scream.
is there a port on the bottom of the carb? mine has one near the drain hose but there's nothing on it
