Hi everyone...I installed this carb on my taotao CY50-B...my 50cc scooter idles but when I open the throttle (even just a little) the engine stops..

Where are you located? warm or cold place? Do you have any non-OEM parts like a new air element? These carbs ship preset for the gy6's...in any case, they are also pretty cheap so it could be they are defective upon shipment too. I ended up returning mine for a slight better quality one ($40) which worked well. Good luck!

Have you adjusted the fuel mixture setting on the carb? May be too rich. It's on the bottom part, near the corner

I had the same issue. Its because the electric choke isn't working and its running way to rich. Either you can put a switch on it to shut the choke off once its warmed up or just take it off. If you take it off like i did you'll have to go buy some JB weld and plug the little holes inside the carb so it doesn't take any air though those holes. Super easy to do. If you look this issue up on Google a lot of people have the same issue. I wish they'd just sell a carb with a manual choke.

That carb works best on that SBC. However..The work is in the carb itself. Casting flash inside metering blocks.Verify jet sizes.Secondary blades 1mm open. Not a square.Choke can needs to be shaved down to idle lower then 1,500 to 1600 with initial start to low.Verify float height and double check base for warpage, 0 backlash on accelerator pump arm.Don't assume. Check n verify.Mine runs great after I did all that.Good luck on your project!Larry

I sold my unit and bought another brand, so I have nothing to look at to help you. Your best bet might to to find one on display at a store and look at it or check youtube. There are carb rebuild videos on youtube.

our engine is a Kohler 15.5 HP - might be a different carb, but I would bet the fuel shut-off is the same. I replaced ours because the engine would die after 10 minutes or so. 10-15 minutes later it would start and run for another 10 minutes and die. Turns out this was not the problem - it was the ignition module (provides spark to spark plug) Replaced that and it now runs fine. If you really think its a carb problem - just order a new carb and don't do a rebuild kit. Been there done that. Installed new carb and it now runs better than it ever has. 10 minute change out. With a new carb it comes complete with the fuel shut-off. Gas with ethanol seems to eat the diaphragm's up. our engine is a Kohler 15.5 HP - might be a different carb, but I would bet the fuel shut-off is the same.

Throttle cable goes in from the top of the carburetor(please open the cap on the carb), then on the jet, you will see there is a hole for throttle tip to goes in. Thank you.

Do yourself a favor call the company and ask for the correct model number of your carb, then do an Amazon search, the I bought works great! I have had no problems with it. Good Luck.

The carbs will work but they do need to be jetted. They are jetted far too lean even for a stock motor. Some carbs also have bad threads from the factory so you should disassemble and inspect before you install

This intake doesn't come with Carb Sticker, and when I called AFE, they told me to call back right before you do a smog check to see if it's carb approved. Most likely they wont be able to get carb sticker. I might have to sell mine after all.

Hello.. I would look up your scooter repair manual.. because most of the Kymco scooters are DC polarity.. This CDI is AC.. and they are a larger sized CDI.. Just Google your scooter model CDI.. Be Safe..

Yes that should be the same carb. I also have a Tecumesh 10HP engine. That carb has been fantastic.

Look up the idle rpm for your bike? Then, perhaps, you need to push that little blue button on the back (maybe once or twice) until it shows the right rpm. Here it says the idle rpm should be 950 to 1050 rpm (that's usually on a warm engine, cold might be a bit lower): http://www.yamaha-motor.com/assets/servicespecs/2008/svcspec_08_royalstarventure_tourdeluxe_805.pdf If it is setup right, that is the number you should see. Mine is right on the money. Alternatively, estimate or look up the max (redline) rpm, maybe it's around 6-8k ? Then the TTO should show that amount, not 3-4K. Hope this helps, HWH

I don't know if it is the correct carb for your bike. I do know it is not a direct bolt on to your intake. There is a whole kit that replaces the intake, carb and I believe the air cleaner. Not sure is the K&N will work either. I ended up rebuilding my CV. There is a lot your can do to your stock carb cheaply to improve performance. You might look up Harley Davidson stage 1 and stage 2 performance upgrades. I think JP cycles has some info on this.

If the governor linkage is different it may not be pulling the throttle plate off the idle screw. You can check the linkage and see if throttle moves off the idle screw as you move the throttle lever. If it doesn't then try to move the throttle (on the carburetor) by hand while the engine is running and see if it speeds up or not. You may have to fabricate a new linkage setup or find the correct carburetor for your setup.

Take throttle lever and move up slowly. Then back down this sets throttle. Next time you move it throttle Wilol work.

Occasionally (with a hot engine) the fuel can vaporize before it gets to the carb, but waiting 10 min solves the problem. Otherwise check the spark plug.

Compare intake and linkage to carb hookup.If head and carb are the same and make a good seal you can make the rest up as you go.It seems most links are never the same as the original app.Sometimes I've had to take the two carbs apart to make the choke or throttle body work. improvise and overcome.

I bought one of these carbs, bolted it on and it has worked great. Didn't make one adjustment. Sounds to me like you have a issue with fuel maybe getting to the carb. Normally what was thought to be too much fuel ends up being the exact opposite. Try taking the gas cap off and starting the machine. Maybe vapor lock? Check fuel filter if there is one, that it is not clogged. Collapsed fuel line? Is the bowl on the carb full of gas when the machine shuts off? Oh and to answer your question, the screw is most likely a idle air screw that can be adjusted to set idle speeds on the carb.
