I need a diagram of the carb to see a pic of what

you must remove the carb and block off the fuel line then remove the bottom bowl screws, separate the bowl from the carb gently and you will see the float(s) hanging. the very center post of the carb body will have the main jet installed ..it should have a flat slot so you can remove it with a screw driver,the idle jet will be a small screw on the side of the carb body and count how many turns out it takes to remove,use a carb cleaner spray into all the jet ports to clean,clean the bowl and reassemble,take care with any gaskets as not to tear them or have them slide out of place.most low speed jets are turned inward gently til it seats then turn back out 1 and a half turns.

The wire should bolt to side of bowl. The right side as the video shows the you flip it over and with the bowl side up there should be alignment marks and it goes in the bottom of carb where white float isMore pics of bowl and bolts that go with it would help.

I’m happy to assist further over the phone at https://www.6ya.com/expert/joe_a3369546f8067589

The carb is probably dirty and ingesting debris or water from the bowl into the main jet at different times. First, I recommend installing an inline fuel filter on it. Drain the old gas. Remove the bottom bowl on the carburetor and check for debris/water and clean it . Also be SURE to clean the brass bolt that held the bowl on the carb as it functions as the main jet of the carb. Clean the bottom hole and the holes on the sides near the top.Reinstall, not forgetting the felt washer that goes between the head of the bolt and the bottom of the bowl (on the outside of course). Use nothing metal to clean the brass bolt. Add fuel sytem cleaner (I like Chem Tool's berryman B-12) to your fuel can to aid in cleaning the inside of your carburetor. Make sure your spark plug is clean (brown, not black) and the air filter is clear. Post back if needed.

You will need to remove the carb and clean it. Remove the float bowl and clean the interior of the bowl and the interior of the carb body. Soak the entire carb, (with bowl removed), in denatured alcohol. Any hardware store will have it. Let it soak for an hour. Then clean it with spray carb cleaner. Spray into every hole you can find. Spray from both ends of the hole if possible, where the spray goes in and where the spray comes out. Pay special attention to the pilot jet (idle circuit), and main jet, (high speed). The diagram below is a generic carb. Please rate my answer.

Remove Seat, Gas tank, side covers, and airbox.
Loosen throttle cable adjuster to give free play to cable.
Loosen intake boot clamp and pick up on carbs so you can get then throttle cables off the carb.
Loosen choke cable holder and remove choke cable from carb.
twist the carbs and pull out left side of bike.
turn carbs upside down and remove the bowl screws.
Remove float pin and float and float needle.
remove all the jets, and set them in the carb bowl
turn the air fuel mixture screw in until it stops, counting the turns, remove it and place it in the bowl.
Remove the diaphram, and set aside.
Submerge the bowl with all the jets and screws in it into a carb cleaning solution.
Submerge the carburetor body in the solution.
Let set for minimum 2 hours. Depending on the corrosion it may take 24+ hours.
after soaking, wash all parts with water, and blow everything out with air compressor.
Make sure you can see through every jet and through the little holes in the sides of the jets.
make sure you can blow through every orfice in the carb body.DO NOT stick wires in the jets.
If the jets are still clogged just soak them overnight. Trust me, i've done hundreds.
Reassemble the carb and put it back on the bike.
Your carb will work like brand new.
NOTE: If you are not familiar with any of this but you still want to do it yourself. WRITE everything down and label every hose, vacuum line, throttle cable, choke cable, ONE AT A TIME.
This is very important to be successful. Take notes

They are on the side just above the float bowl, they are sealed with epoxy.

Your carbs main jet is most likely blocked. When the throttle goes off the idle jet to the main jet there isnt enough fuel flow and the engine stalls.

You need to removed the main jet and run a small piece of wire through the main jet to clear it. This is a good time to look at the inside of the float bowl to see if you have excessive water, rust or dirt accumulating that is a sign you should clean and drain the fuel tank and lines as well. The main jet is actually the bolt that holds the fuel bowl on the bottom of the carb! You need to look very close at the jet near the top of the threads to see the little whole there and clean it. A wire brush to clean off the threads and fine piece of wire strand to clean the hole will do the trick!

If you dont have a bowl type carb you will need to remove the carb from the fuel tank and locate and clean the inlet screen and main jet and then remove the fuel tank and clean it out too.

Good luck and be careful.

I could not locate a diagram of your machine's carburetor. I can tell you, for certain, that the carb does have a rubber drain tube that goes from the bottom of the float bowl and vents to atmosphere beneath the vehicle.
There are three required ingredients required for combustion: fuel, compression, and a spark (at the right time). Try to find out which of these are missing. Loosen the drain screw on the float bowl. Is fuel present? Check the compression - you've got to see at least 140 psi for anything to happen. Pull the spark plug and crank the engine. Is there a spark?
If it has sat for an extended period of time (more than just a couple of months) then the carburetor will be plugged with fuel varnish. It is very easy to think you've got everything cleaned, when the jets are still plugged up. I would take the carb apart and remove the jets. Hold them up to a light source and look through each one. If you can't see through them, there's the problem.

more than likely its a clogged jet in the carb. pull the carb off and flip it upside down. take the bolt out of the bowl and pull it off. use a flat head to unscrew the jet in the tub in the middle. clean out the high idle jet on the side and replace in reverse order.

i'd say the carb is gummed up especially the pilot jet (#16158) in this pic of the USA carb. may have to remove the carb & bowl and then remove the pilot jet (w/ flat head screw driver) and clean out the tiny holes.

-OR-

the carb slide is installed backwards (turned 180 degrees). its #16025 in the pic. i've done this before on my daughter's XR70 and Z50. you'll know if its this when you move the choke lever, RPMs increase and decrease.

hope this worked for you and was fast enough.
