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 👍👍

Do exactly as he says and it will work. Cleaned my "Coolster F5" carb and it worked right away. Excellent teacher.

[@noot7109]

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.

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!

WOW, the best instructive video about carbs so far , thx a lot man , greetings form Egypt

[@Spitfireseven]

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.

[@Spitfireseven]

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.

[@Scooterswapshop]

your welcome

[@drierdan]

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.

[@Scooterswapshop]

Glad to help

[@booshfitz6809]

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.

[@vaughnsawyer6619]

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

[@Scooterswapshop]

thanks

[@loukydookie]

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!

Bond the carb to the chassis. put swollen gaskets in oven @ 200° for @ 10min. or leave in direct sunlight for 20min.

[@Scooterswapshop]

just replace them

[@garybloomlaw]

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

[@jimboharry6571]

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

[@Scooterswapshop]

Glad it helped

[@nehpetssaid]

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.

[@Scooterswapshop]

...

[@seanmayo206]

You dropped some knowledge. It's much appreciated. . If I bbk to 72 an it was 50. What size jet should I use at basically sea level an does it make sense to put the fuel filter in-between the tank an vacuum pump?

[@hunterchung7070]

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!

[@beyeriii]

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.

[@Scooterswapshop]

or just replace it

[@paulmaland2227]

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.

[@upALLniteSLEEPallDAY]

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.

[@Spitfireseven]

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.

[@Scooterswapshop]

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?

[@Scooterswapshop]

clean it your self and jet it properly

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.

[@SnowstormGaming]

Tip for if your gasket swells too much for the bowl or whatever, boil them in water for a min at a time and usually, it will shrink back to the original size

[@Scooterswapshop]

yep good tip

[@partymanau]

When u remove them, soak in light oil so they dont shrink. As the gasoline they have live din for ages leaves, they shrink.

How can you access the mixture screw without completely disassembling the exterior coverings. Should the mixture setting screw have been set a more accessible position?

Depends on the bike. If it’s a Chinese scooter or a bike with a lot of fairings too have to take the fairings off. This isn’t something you have to adjust all the time

So I have a Tao Tao 50 cc scooter, the carb looks exactly like this one. It only has 35 miles on it and has been running like crap. The factory carb is sealed so you can't remove the 3 screws there is no head on them. I ordered a brand new carb online and put it in, it fires right up but only idles, as soon as I give it gas is kills. I am lost, any ideas?

You likely need to jet the carb

is there a port on the bottom of the carb? mine has one near the drain hose but there's nothing on it
