Carburetor Rebuild on 2 cycle Stand Up Scooter Part 1/2 

Thanks, donyboy! I have a similar carb. on a cultivator. You've taught me all I know on repairing & maintaining yard equipment.

Got my scooter up and running thanks to this video! I'll admit I messed up the first time and didn't notice. Boy did that cause a lot of grief. After watching the second time, my father and I rebuilt it properly and my scooter fired up first pull! :D Perfect timing too since I'm going camping tomorrow morning too. Thanks for sharing all these videos, I really do appreciate it. I hope you don't mind me downloading all your scooter videos in case I ever need them for later use (With no internet).

THANK YOU SOOOO MUCH. The gasket kit was a lifesaver.

I am so glad I ran across your video. Thank you for posting this. My mini chopper is running better than ever now. I got the rebuild kit for $3.70 gotta love it.

Great explanation on the lever heigth adjustment ! Wish i saw this 1st . Most dont mention or vague or chasing complications

Seria muy bueno se tradujera al español. tienes muchos seguidores en este idioma

Thank you for the detailed video. It helped solve my issue of my scooter not starting. Thumbs up.

FYI make double sure that the rubber tip of the needle is clean and that the hole it sits in is clean too or it will flood fuel

This video is still helping people a decade later. Thank you so much

very nice vid:great lighting, camera zoomed in nice. Very detailed. Seeeeeet!

Great video! I should have watched before I too my carb apart. Do you have any videos showing how to put the throttle return spring back into the other side of the carb. I probably shouldn't have taken it apart, but I wanted to get everything clean and all of a sudden the spring flew out. Now I'm screwed! Any advice??

Cool vid. I'm still waiting for a coil for my scooter. That might be why it's always had low power. If that doesn't fix it, I'll check the muffler. And if that doesn't fix it, it'll probably be too expensive to fix. The piston looked a little scratched, not scored, just lots of thin scratches.

Great video dude !

@Mrtocoolforyou12 not exactly sure what that is called, i think the kit u need is k10-hda

Very help full!!!!!!! Thumbs up

Thank you brother for such as oriented videos, I always watch them, nice thanks!!!!!!!!!!!!!!!

@maksnajper The compression isn't low. I was just a little worried about the rings and piston.

you didn't mention anything about cleaning out the jet. that's a very important step.

90% of 2-stroke engine problems are just due to dirty carbs or worn gaskets.

This looks almost exactly like the carburetor on my Hangkai 3.5HP outboard motor. The motor looks like it might be the same. It's a 2 stroke outboard boat motor that is water cooled. So it has a water jacket installed on the engine which a lot of people keep saying it looked like it came off a weedwacker. You ever get a chance to work on such a motor? I'm sure it's fairly similar. Also if it is almost exactly like the Walbro carb, is there an aftermarket one that will give it more HP or work better? If anything I'm more interested in the reliability factor rather than gaining any HP. Thanks for your input!

@1972FordF150 thanks dude

Carb cleaner destroys rubber parts. Avoid spraying primer bulb and the orange or black rubber valve. Also avoid spraying meter diaphram, gaskets and pump diaphram. Be especially careful to avoid getting spray in check valve which has small rubber disc inside.

Carbs need cleaning when the engine wasn't run dry (till it dies from lack of fuel not just emptying the tank manually) before storing it for the winter months. If it's "put away wet" the gas turns into a varnish. As long as you are regularly cleaning the fuel filter and regularly clean the air filter with gas then oil it carbs rarely need to be rebuilt. And at under $10 for a new carb why bother unless you want it running in under the week it takes for its replacement to show up

heyy man, i have the exact same scooter and i am doing some upgrades, and i wanted to know what carburetor i can use to replace mine. i have my chinese one but i would like to get a walbro WYK or ? what can i use thankss so much this will help me a lot. in the video you showed the walbro.

Spring is included in rebuild kit? first time i heard that.

Hey Doni, I have a barrel style that drips gas from the venturi while it's off the unit. I have rebuilt it but it's still dripping and causing it to flood and very hard starts. Whats the cause?

i don't know off hand, the only thing i can say is if it looks identical then it should work

which wyk carb did u use? I ordered a wyk but the barrel is bigger and the suction hole doesnt line up with the hole on the intake on the cylinder

did you get the throttle cable out installing new one tomorrow

at 4:55, I'm trying to rebuilt mine, just a quick question, can you blow air through the crossed middle hole ? I presume its the passage for the main jet ?

i have a brand new 33cc 2 stroke engine... i want to know if i put a 14mm carb on it will it go faster?

also on the bigget of the two gas lines should you be able to blow air through it? i can see that its not blocked when disassembled but when i assemble it i cant seem to blow air through it. Please respond

Its like the one on my redmax blower i use shipping tag wire and air carb cleaner like video

I have the same carb on a midi moto and when I tried starting the bike petrol would just poor out of the carb, cleaned carb and same thing, any idea what it could be?

Can you show what goes where does the diafram at the bottom or does it go above the seal

Hi Don, no scooter questions but would like your expert opinion. My cs 300 symptoms are, starts after many pulls. Runs runs runs, revs fine but if i don't hold idle up a bit it dies, then pull, pull, pull, nothing. Brand new carb and filter lines look good. Truly frustrated, specially after buying new carb. Will keep playing with it. Thanks Don.

Dony what is the brass phillips screw for near the fuel screen ?

Any info on tuning the main jet and the other one in the center of the barrel?

how did you get the throttle cable off the top of the carb?

Im use this carb on my sprayer but after running every single time i put it off always hard to starting up

ok thanks man, and do you know where to get those diaphram kits i cant seem to find em. K1-WY

@donyboy73 No problem

OK, the site im getting parts from has the Walbro WYK-33 barrel carburetor, Walbro WYK-58 barrel carburetor, and a Walbro WYK-194 carburetor. But no WYL's. would any of these work do you have any of these? thanks

Do you know what model carb this is? I don't want to rebuild it I want to replace it with the Walbro but don't know the model #.

i was told you.can buy the air filter and cap at home depot because its same as a weed whacker???

@MrMoterKid if u have a low compression check the piston ring/s

where can i get a walbro kit because no one around me seems to carry the kit who makes walbro carbs?

Hi Donnyboy, I have been trying to obtain a diaphragm for my carby to no avail, its identical to the one you are repairing in this vid only the diaphragm I have has the 4 holes for the screws and the 2 holes on1 end of it but mine has a 3rd hole in between the 2 holes at the end and all the ones I can find dont have the 3rd hole and I noticed the one you are fitting does not have it either can you help me here please

wow thank you!

couild be the WYK or WYL, just match it up

Donyboy, where did you get your carburetor kit to buy, i, got the same type of carburetor on my weed wacker but cannot locate a carb kit Thanks Winston.

as it states on the can "Carburetor Cleaner", DO NOT USE carb cleaner on small engine carburetors. Unless your cleaning the Body of the carb. Even at that it needs to be the body that has the rubber tip on the needle. If it has the rubber o-ring at the base of the needle seat and you use carb cleaner it will destroy the rubber and all rubber parts it comes into contact. Its best to use Foaming engine de-greaser with the small red tube. Put it next to all the small inlet holes and spray, it will remove all the debris out of the carb fuel passageways. Good informational video.

hi I have one of those stand up scooters and when I tried to remove the inner needle (the one in the top screw ) the needle broke. can I get just a needle or do I have to get the whole carb? if I can get just the needle please tell me where. thank you

Hi, have you ever changed the clutch on your scooter?

@gujada9776 watch part 2

What would cause the carburetor to flood. I did this rebuild and the fuel won't stop flooding in the carb

whats the part number for that rebuild kit

Donyboy what is the rebuild kit # ?thanks Carl

First i would clean it with carb cleaner then blow the crap out of it with a air compressor like at 80psi lol then i guarantee it will work like new because i done this like 20 carbs and never had a problem.

Hi, on my generator the carb is virtually identical similar but has primer bulb separate , only problem it cuts out under higher load ,could it be mixture ? How do I adjust mixture there is no screw ,it even runs with the choked on indicating its to lean maybe ? Any tips. ?

Wer can I get the kit to do it pls let us know

thankss.. i have exactly the same carb, on my leaf blower.. I NEVER NEVER GET ANY LUCK FROM REBUILT!! every god dam 3 year. i buy a new back pack blower... and im getting stick of it of replacing the blower... i wish they come with electronic carb... soo soo today the tool is hanging up and the blower is still apart on the floor.. :(

what to do if the gas doesnt go to the carb?

what is the screw on the side with the spring on it

Hi, Can you tell me the correct gas/oil ratio please? I'm getting everything from 25 to 50:1

Where is the 2nd video for this

@gujada9776 u can get those kits at mowers4u dotcom

Gee wonder where the gas screw part was

If the diaphrams need replacing you may as well buy a new carb rather than a rebuild kit for them.

Can i dump this on ultrasonic cleaner

kk thanks

how to install

New one $14

YOU CAN BUY A COMPLETE carb on ebay for under $20

That is a load of shit took me ages for nothing cheers pal!
