- เผยแพร่เมื่อ 3 ส.ค. 2014
- For a good understanding of how your GY6 engine enricher(automatic choke) operates, and how to test it, watch this video. The enricher shown in this video(which is a wax motor) was removed in perfect working order from my 150cc/QMJ157 GY6 scooter. If you have any questions, please feel free to post them in the comment section.

I always wondered how that worked. I had to fit a new carb to my quad and from watching your video I could see that the old carb choke had never worked. Thanks for such a great and clear explanation of the system.
Many years ago, Frigidaire refrigerators that had an ice dispenser in the freezer door had a device like this that opened the chute door so ice could pass out into a cup. Frigidaire called the device a "hot wax motor". - - In that application it was powered by 120 volts AC here in America. They were reasonably dependable. - - Thanks for your videos.
Great Video. Good explanation. Made it very simple. Thanks.
Great video. Nice clear informative pace.
I was scratching my head off figuring out how it works. On disassembly i found a metal coated disc sandwitched between two wires. I thought it was a piezoelectric device which would only work on certain voltage and frequency. Now i know that it was just a heating element which would melt and expand the wax inside the copper housing pushing the plunger outward.
Great video with important info. Thanks
Man what a great video. Thanks a lot 👍😀
I love your engine examples. 150 cc, Model IP57QMJ. I have a Xinba in a 2018 IceBear Cyclone trike. Doesn't burn a drop of oil, and even though I have to warm the One Cylinder up to stay running, the 80 miles to the gallon and at 3/4 throttle it's going a smooth 50+, with 11 or 12 grams rollers, gets off fast, then ease it along up to fifty.
Thanks for watching!
7.5 ohms on mine. Also same on another vid. Mine has a ballast resistor. Yours may not Manufacturer may use higher ohms instead of resister to limit current. Like you stated, there are differences between applications. I would say one is good down to maybe 4 ohms. Check to see if there is movement in a couple mniutes when voltage we is applied
Much needed info. Thanx

Thank you! Glad you enjoyed the video. Be sure to check out my other videos, share, and rate thumbs up. I only use 720P. In the future I may use 1080. Higher quality = larger files to be uploaded, with longer upload times, which is not good when using slower upload speeds.
I understand slow upload speeds believe me. But I think they worth their time (perhaps uploading at night while you sleep) since you have undergone all this effort for the video. I think 720p is enough but its the transcoding algorithm youtube uses that blurs the video.
Excellent tutorial!

Hey... thanks for the videos. .. i got a Derbi Gp1 03 for our motor pacing on our rode bike ...the other day the motor stop working.. I check the ignition and is working, check for the spark the spark plug to the head, and is good spark.
then i move to the carb to see is gas was coming down and flow of gas was present. after all that I took the elect. choke but I didn't check the travel of the shaft ... what other cause can be creating the non start ...also I do have good compression
Thank you, there is little information about this. Now i know mine is stucked
Think you solved my 3 day dilemma of adjusting and cleaning the carburetor. Thank you.

WORKS FINE NOW. NEVER FOUND EXACT PROBLEM.
OK.
guessin choke works like car thermostat , expanding wax when hot in a small metal box . wonder if it can get stuck in open position so starting will not work and better to loosen choke screws and lift it out a bit to see if starts.

Rogier Schutte Thank You Rogier! Be sure to check out my other GY6 videos, as well as all my other videos. Please share and rate thumbs up.
Is it safe to apply DC voltage to this since it is powered by the yellow wire, directly from the stator AC output? The wiring diagrams also shows that it has a resistor/diode in the ground side of the wiring from the enrichment valve. Thanks for the video.
thats what iam wondering aswell
So if one is having trouble starting their engine on a cold day, removing the whole unit will help the starting since the plunger inside may be stuck in the extended position. Removing the unit will act as though the plunger is retracted.
Some people remove the enricher and replace it with a flat plate.
@@electronicsNmore Although, that may cause it to run too rich when the engine is warm, no?
B
This choke adds air and fuel on start. Up. If. Its. O. ring leaks. It will lean out the mix. So no a block off plate alone will not work
When my scooter warms up after a few minutes of riding it's power output seems to falter. Barring all other possibilities Would this be an indication of a faulty choke?
Sounds like carburetor issues. You can try removing the choke and covering the holes with a metal plate. If the problem goes away, then the choke is the problem. Make sure you warm up the engine, or remove the choke on a warm day, otherwise it will be hard to start up the engine.
Could I use an electronic choke carb on a 4 speed 4 stroke pitty and would it really improve performance?
thanx,does it get power thru the temp unit..my yamaha nouvo elegance has this problem.i did replace carb with new. must be broken wire somewhere
are these things chasis ground?
nice video, thx alot for that, but dose it matter where + and - are put at, and can i use a power supply with 13,7 volt's ???
13.7vdc is fine. It shouldn't make any difference + or -.

Is this the same enricher that is used on the 2-stroke Yamaha BWS/Zuma? Thank you
My TaoTao 50cc scooter has been really hard to start after 1 yr ownership. I live in FL in a warm environement. When cranking cold, it fires and putts once or twice before dying, I time having to roll it down the driveway, tickling the throttle until it goes due to the engaging of the autobelt/clutch as it catches.. After it tries to die as I give it gas into a corner, it'll rev up and after 3-4 minutes of continuous running, no issues starting or idling anymore. I pulled the automatic enricher out and measured like you did. It's 3/4" cold.. When I turn on the key, it does not move so I assume that the scooter has to be started before the pin will expand down? I use nothing but 100% gas (no 10% ethanol mix).
I don't think the automatic enricher is bad. Maybe a carb jet or air/fuel adjustment at cold start? What are your thoughts?
Thanks!

Would you please tell how to check if the harness to the bi starter connection is giving voltage to connection , even if that is the case..How is this cone ?
Hope you are answering questions. I have a resistor a little white box that ties in with this auto inricher was wondering how or were it wires in?
Hi Ross. Power for the enricher usually comes off the stator. Thanks for watching! Be sure to look over my GY6 video playlist below and share.

i disconnected this 6 years ago. i've been driving with choke on this whole time. no wonder i have poor mileage.
😂😂
@@Miggysteezhow should it be diven with on or off
What if it revs up but only touching the 2 bolts with metal will turn it over? And when it starts and runs its a little choppy for the first few minutes. Also, it only does this if it sits for at least a few hours. New spark plug didnt change anything. Any help would be greatly appreciated.
My scooter only starts when it is cold. And after it warms up and dies I struggle to start it and i can smell lot of gas. Also when i get it to start it it idles get worse and eventually stalls. could it be the enricher giving to mucch fuel and not closing the gap
where should i tap the wires, should it be dc or ac voltage, any specific voltage?
Good

Hello, how are you? I just wonder what if we do not connect the power to the enricher. Thank you.
sir im from Philippines i also have a gy6 engine and dtype carburator as well but in the morning i need to add a lil bit of throttle to it for it to start and warm up what you think is the problem??
When is extended reduces de amount of air or fuel to the engine?
My scooter has a
spark but when I turn it on it does not hold at the minimum, that is to
say it goes off at the minimum and then I can not turn it on until the
other day ,,,, I think it is the carburetor thickly the electric choke
also called (throttle). What do you say friend?
Having a problem with cold idle on my 49cc scooter. When it first fires up it runs ok for a few seconds then the idle goes up and down and usually stalls. If I touch the throttle at all, it stalls out and is difficult to start again. Could this be a choke problem or a mixture problem? I just bought the scooter in May of 2014. Once it's warmed up it runs fine.
You should not have to touch the mixture screw. I would inspect the o-ring on the enricher, and if it is OK, then suspect a carb problem.
I read somewhere about replacing the carb it needs cleaned first. something about a wax that there shipped with. any ideas what I should do. ? I have a new carb from Redcat.
Never heard that. I heard of plugs.
Can you check this choke by turning on the ignition and watching it
I seen in 1 of your replys.. About a cracked intake manifold.. Mine has a small pice broke on the edge screws go in gasket covers looks like it still seals. Didnt think it would be a issue..
Use RTV sealant to ensure no leaks. Thanks for watching! Be sure to watch my "GY6" video playlist and share.
@@electronicsNmore But not on the exhaust manifold!!!
In my situation my electronic choke is closed and will not return to open for the next start.l have to start it and keep revs up until warm and then it runs perfect.
hello there...my engine is Air cooled, and i want to fit an water cooled carb with this kind of choke...if it is possible tell me how to do the conectionn of choke...looking forward...tnx
Yeah im not sure. Never heared of that. I have a air cooled and a water cooled scooter the carb is not that much different
Hi.. There is not a wire diagram of it (Connections from it to the Stator)?
You can find schematics online.
Ok.. Let me see if i understand.. This Valve is not a thermostat, when you turn on the bike the Valve needle start to go outside for about two minute, the needle function is to stop air flow and slow down the motor revolution.. The needle will stay in his same position while the engine is on (There´s not fluctuation, the voltage will stay constant at 12 V on his terminals), when you turn off the engine the Needle back to the inside position.. I am Right? if so, i just only connect one cable to ground and another to some cable that depend of the Start voltage after use the Bike Switch on "ON".. I just need to know that for make it myself.. Thanks for any help :)
So what needs replaced if the resistance is only 7 ohms when we are testing the auto choke? We're troubleshooting a Helix 150cc go kart that starts up fine, runs great for a bit, and then starts bogging down/won't go after it gets hot.
Joanna Morelandgyough
electronicsNmore I watched you're video about the GY6 enricher, but can you tell me which of the wires (Green or Yellow) is the + and -, Thanks
Greetings
Frans
The headlight and enricher operate using AC off the stator. The enricher will also work using DC as shown in the video. The enricher is a resistive device which creates heat in order to expand wax driving the piston outward. Should work fine no matter how you connect it up. The yellow wire is normally connected to the yellow wire from the stator.
Thanks! I wondered how it worked!
Hi,i have question,about how the the choke get power...I mean i tested on the mmeter show it goes up and down,each time i throttle the gas,theres no set volt to it..I thought it would be a straight 12 volt to it
It gets power from the stator on the crankshaft. As you throttle up the engine spins faster and the stator will produce a higher voltage. It isn't powered from the battery so no fixed voltage. It makes sense tho because if your engine is throttled up then it'll warm up faster so needing less time with the choke on.
Wonderful
Thank you
what a job OF that PART in the bike?
Thanks for watching. I don't know what you are trying to say.
thanks for ur reply me :)
i have joneway scoter , i asking u what is the jop of this part
Automatic Choke
?
This part makes the scooter run richer(more fuel) until the scooter has warmed up.
Thank you my brother, I understood now :)
Hi! I have a 50cc CPI Oliver city.... I just replaced my carburetor with a new one ... it starts and runs fine... idles fine... but when I drive it for about 2 miles going 40 mph, I lose power then it dies. I pull to the side of the road and starts back up again. Drive it again for about 20 feet then loses power then dies again.. seems to be losing power and die when it gets hot? Any ideas?
Have you solved this problem?? Mine too
Not rich enough?
Hey... thanks for the videos, i have hard time to start my scooter on the morning. it take me about 10 to 15 min to get it start. (yes, it is only on the morning, afternoon is no problem to start the engine). any idea what is cause it?
Either a faulty enricher, faulty carb, or you need to adjust the valves.
electronicsNmore I
@@electronicsNmore not true you almost never adjust the valves.
@@arberfilms5998 Incorrect. The manual says how often.
@@electronicsNmore every engine I’ve owned I’ve never had to adjust valves. And they run exactly like new. What do you mean dude?
I installed a new carburetor on my gy6 150 engine. When I first start the moto and drive it the bike feels like it's missing and surging. After the engine is warmed up it runs fine. I live in Acapulco Mexico so the weather is always warm so it's not a real cold issue. Is my problem in the auto choke?
Could be a gasket leak, or enricher problem since it started after the swap.
Can these Carburetor chokes go bad in time
No mention of how to connect, is the green or the yellow live?
Hi man, with my 50cc scooter when i drive it cold in the morning like 8deg weather, it usually bogs when i drive it afternletyingnit idle for like 2mins bit it will be fine afterwards like no boggings when warm and very responsive. Is there a possibility that the auto choke is causing my carb to flood during that period that’s why it bogs like there’s too much gas from the choke?thanks
Definitely a carb or enricher issue.
Please help! So, I stripped the enricher wires and put my volt meter on there. I started the scoot right up and the voltage was around .5 to .7 then after almost a minute it hit 1.2 volts. Once it warmed up the voltage dropped to .1 and then the bike died, as she always does. Should I be reading around 12 volts during this operational test? I can manually route 12 volts to it if I need to. My scoot is unusable because of whatever the issue is and I now believe this is where the problem lies. Thank you in advance. 🙂
Is it normal for my auto choke to heat up even though the engine is in operating temp for a long time already?
Hey, I see y brought a MCI Alien sport 50cc moped, and the electruc choke works, however the rubber that the needle on the electruc choke goes in to is perished and broken andnim need to replace it, but I don't know what this part is called.
If you know please let me know, thanks
You need to look up parts for your make model scooter online.
Hi. Do you ohm it out. Hot or cold ? Thank you. Bill
No. Just test as shown in the video.
Does the choke cell annoyed need to be greased in anyway?
No. Just make sure the enricher O-ring is not dried out/cracked. Lubricate it with silicone grease.
I have a gy6 150 after it warms up it won't idle without me applying gas do you no what it might be
Maybe you need to adjust the idle speed screw. Please refer to my GY6 carburetor video. Thanks for watching!
How high should the rpms be when warming up? My bike is a 150cc tao tao. Lately my rpms are shooting up to 3500-3900 and the wheel spinning. It comes back down to 1800-2000rpm after it warms up but it stays high for about a minute. The first year it was running smooth and only shooting up to upper 2000s when warming up. Thanks in advance for any advice.
Definitely a carb, enricher, or cracked/damaged vacuum hose. My scooter was set to idle at 1500rpm. If you never adjusted your valves, then watch my other video.
Thanks electronicsNmore. I've upgraded all my vaccum hoses as a process of elimination. I havent used any carb cleaner yet. But I'll try replacing the enricher next since its only $10. My manual for my 150cc says to set it 1800+- 100(I like to keep it a little higher around 1900. It gets sensitive around 1500. I think my next step is 1. carb cleaner then 2. enricher replacement.
My enricher itself works fine, it extends/retracts normally, O-ring is good on it, but my idle doesn't increase when I first start it in colder weather. Idle is the same as when it is warmed up. Blew some air into the channels and they are both clear. What can make the fast idle not work when cold ? I removed the enricher altogether with a plate and there is no difference, but the scooter runs fine when warm, just no higher idle when I start it.
Sounds like a carb issue.
Might be out of adjustment. I'm trying to figure out mines now. U ever figure it out?
@@dmo848 Sold the scooter. Ran fine after 3 minutes of idling, just that the high idle didn't work when cold. Hope you figure your issue out.

What operates the automatic choke? Where does the power come from?
Thomas Flynn Hi Thomas. The automatic choke gets power from the stator once the engine is started. AC voltage is supplied to the enricher. The enricher works with both AC and DC.
Thanks. Be sure to share my videos with others, and rate Thumbs Up.
where is the stator? on crank shaft?
Alos, mine runs good but, when you sit on it it won't move? does it have a clutch in rear wheel or bearing?
You need to remove the CV cover to inspect the belt/clutch/variator.
Thanks.
Thanks! I did and no clutch
@@thomasflynn642 Search in youtube how to change scooter belt and you'll see a lot of videos about it. When you take off the cover on the left side where the crank start is (easy to remove) you'll see how it looks. Perhaps your belt broke, which is why it won't move. The clutch is on the rear wheel, which you will see when you remove the cover.
Hi - I have a 2012 zuma 50. Starts, idles, and goes on 1-3 mile trips perfectly. After a little longer trip it does not want to idle and will cut off eventually. Starts right back up and if you get into the throttle right away it will run fine to get you home. The hotter the engine gets the quicker its wants to cut off. After it sits for 10 minutes, it will idle just fine again. Does this sound like an enricher issue? Thx
Hi Richard. It does not sound like the enricher. Since it's heat related, I would check the ignition coil, it may be breaking down. Also check the pick up coil(part of stator), and CDI. You can also buy replacements cheap at the link below. I have a video under my GY6 playlist. :-)
bit.ly/2ceq08A
I let it idle from cold to hot without driving it today. Took about 20 minutes to start sputtering. I noticed it started crackling somewhat, At closer look, I could see sparks from around where the spark plug screws in. An obvious clue for you I am sure????

Any idea why my gy6 on a baja reaction go kart will start and idle fine but when the peddle is down about 2/3 it bogs down. Does this have anything to do with the enricher?
Possible problems: Restricted fuel flow, carb not properly adjusted, valves need adjusting, or timing marks not properly lined up.
update, fuel flow is good, got a whole new carb (idle much better and doesn't die) no matter which way i turn the carb screw I'm getting almost the exact same problem, adjusted the vales just like your video ( they where really tight), any video on how to adjust timing marks?

My GY6 valve adjustment video shows the timing alignment.
Heres 1.. My scooter trike. On a cold start it HAS to be hand choked for it to start.. With my hand over airbox hose it starts right up fine. After its been warmed up it starts just fine. The carb is brand new 20mm carburetor. Stock jets 49.5cc trike with a 50mm bbk stock airbox
Work backwards from what you replaced. If it worked before, you did something. Usually the carb, carb/intake gaskets, or enricher would cause that problem.
Before the build it would not e start once it got cold out i never tried hand choke didnt know about that before build..
Im guessing it might have something to do with auto choke i dont know yet but ill be testing it to see. Timing is set to tdc gaps at 005 going to take exhaust to 006 see if that helps.
If I stop this starter..there is any problem for my scooter??
I put rubber to the starter to stop it and the scooter become better in everything..sound..fuel consumption
Hello, I have a 150cc velocity, while warming up it goes up to 4000 rpm then goes down then up again. While driving and stopping the Rpms go down to 2 then back up to 4 and while riding the scooter feels like the engine choking out or the plug fouling out then it 0j00umps. Need help with this. Thank you
+Tom Hufford
Hello Tom. You can try ruling out enricher leaks by making a small plate to cover up the holes out of sheet copper from a hobby shop to go between the carburetor body and enricher base that the enricher pushes into. Once reassembled remove the enricher and give it a try. Also inspect the intake manifold for cracks/leaks and valve adjustment according to my other video.
Thanks For Watching
I will give that a try.
Would the auto choke be going out?
You would need to remove it and test it.

I have a gy6 250cc automatic brand new from factory. wont go over 55 max and only gets up to 5000 rpm out of 12. Any ideas?
Try adjusting the roller weigh size. They could be too light.
My scooter has been having a problem where it needs throttle for about 5 seconds to start and stay running without shutting off. It runs fine when started however, aside from a foul smell of rich gas coming from exhaust. From what I know, the carburetor is clean, new oils/gas. Oddly, turning the air/fuel screw seems to do nothing in regards to RPM.
What can be the problem? I've been told to check compression but I don't have the tools for that.
+HelixObscura
Sounds like a faulty enricher, faulty carb, or lastly a cracked plastic intake manifold elbow.
I have a similar issue except once I warm it up I go to drop it off the kickstand and just loose all power then dies out once the back tire hits the ground.. I just cleaned the whole carb like 4 times because I didn't do the pilot jet good enough each time so I'm confident the carb is clean also I can't find any obvious leaks any ideas where to start next? Thank you for your videos I find them to be most helpful, simple and direct.
I have Aprilia Leonardo 150, and the current from the cable that gives power to automatic choke is about 3,5 v, I think it should be about 12 or more v, why is that happening?
Did you measure using AC volts? or DC volts?
electronicsNmore Hmmm, can't remember, I will answer that when I get home, thank you.
👌👌👌👌
i'm still learning, what does the enricher do?
+Red Pyramid
Hi there. The enricher is used to to adjust the fuel/air mixture when the engine is first started up(Like a choke). The engine will run at a higher RPM until it warms up.
But does it regulate only the fuel or only the air ( both ????!!!!)
Do you happen to know what the size of the o-ring is. I have a 2020 taotao blade 49cc.
No, but you should be able to try a few out. Look for one of the correct diameter that isn't too thick to keep it from going into position.
@@electronicsNmore today I went to a manufacturing wholesaler who sells O-rings and when she tried to match up the original o-ring she couldn't find the right size. When she measured it she said it doesn't exist especially in metric as that's what it is. I bought the next size bigger because the next size smaller would have been way to small. That's Japan's for you!
Hi man. Everytime i turn on my scooter cold first thing in the morning, i have to let it warm up for like 5-10mins and can't drive it straight away becausenit will bog on 1/2-full throttle. Weird thing is when if it is warmed up, mo jogs and runs fine. Could it be auto choke is faulty?
Definitely a carb problem or enricher problem.

Hi, I have the exact same problem with my YAMAHA Zuma 2005 scooter. Did you ever find out what exactly was causing the problem?
@@SharokD hi man. After figuring out for weeks what the problem is, i switched my fuel petcock from vacuum to manual switch on/off fuel valve and it solved the problem as carb is not fuel deprived. Now i can use my scooter after warming up in 4-5mins with no bogs. It is always good to warm up a 50cc scoot after hours or days not being used. Before 10mins is just quite a long wait before i ride on. I am quite happy with it now.
@@ninoechavez1402 Hi man. Good. I also fixed my scooter bogs problem. My scooter doesn't have a petcock, but I fixed its bogs problem by adjusting the air screw on the carb. I saw an article that said turn the screws clockwise 3/4 turn and that did it for me. Awesome.
