I got my replacement carburetor in the mail today, and it fits good and looks good, except for the wiring harness on the electronic choke is a different connector from the stock one. Is it ok for me to remove the wires from the new one and insert them into the old electronic chokes wire housing?

You will need to splice one in to the other. You also might want to try and see if the old auto enrichener fits the new carb.(no wire splicing)

You also might want to try and see if the old auto enrichener fits the new carb.(no wire splicing) Ok, I’ve kept the old carb and enricher on for now, but now the issue I am facing is that when I first start it up, it idles, but once I rev it a bit , it will idle for a second and then die. When I try to start it it won’t start up again unless I let it sit for a minute or two first. This started when I tried to adjust the air fuel ratio, and I think I may have done it wrong, but I am unsure how to revert back to where it was before. About the splicing, will polarity matter or will it not affect it? The old enricher definitely won’t fit, it’s about a third the size of the new one. |

Your new carb may not be jetted the same as the old one. You will have to take the bowls off of both of them and check the jet sizes. |

I got it spliced in, but same symptoms. It dies after about 2 minutes of running, and tries to die if I rev it when it goes back to idle. Once I wait for a few minutes, it starts right back up. |

Did you try the choke to make sure it was working correctly after wiring it in?

It's possible that once the choke goes off there is too much air.
If you put power to the choke it should extend. This blocks off the channel it sits in. If the choke is staying on it might give the symptoms you describe. Would be good to rule it out.

I'll try that test hen i get home, i was thinking its an air leak, i know i need a new exhaust gasket, as i can often see oil condensating around the gasket, but i haven't checked any of the other gaskets for leaks yet. I'll post an update soon. |

These tgb scooters are touchy as hell,ask me how I know cause that's all I've ever known it could be an air leak and what size jets u running sorry just caught all your posts?? To be honest, the guy I bought this from told me it needs: - some clutch parts, which I’ve just ordered - carburetor work (I cleaned it, but it then started dying after few minutes of idle, so I bought a new one) - a charge on the battery. He said it is a brand new battery which I trust cause it holds pretty good charge. I’m actually pretty stumped. I think at this point putting much more money into this wouldn’t be smart. It’s 11 years old after all. I’m unsure of the jet size, I’m not an expert with carburetor and 2 stroke repair, i just know the basics pretty much. I got it started with the new carb, the auto enricher being spliced in didn’t seem to change anything, except now when I give it gas, it stays up in high rpms and slowly drops back down to idle, rather than just going back down to idle. If I give it full throttle, it bogs and dies. It doesn’t start again unless I wait 5 minutes, then it idles and rinse and repeat. I’m stumped, and I know the variator will help cause the current one is so loose every so often the engine has a hiccup cause the variator face gets caught on the belt cause it’s so loose. That may have to do with the struggle for it to run with the headlights on. I’m at a loss of things I can think to try at this point... Here’s a link to the carb I bought: m.aliexpress.com/item/32824292402.html?trace=wwwdetail2mobilesitedetail&spider=y&productId=32824292402&productSubject=19mm-Carburetor-Moped-Carb-for-TGB-101R-101S-203-303R-Acros-Tec-Delivery-F409-Laser-R50XAny ideas would help... |

With a new scoot I,d go right back to basics ,from the reed valve to the air filter you will have to get used to stripping and refitting the various parts for servicing,watch Brent,s you tube videos,be methodical it gets easier every time.if you need my 'guess' it,s an air leak or a acc, cable out of adjustment.sort the CVT out first it may mask the real issue.

Geoff That’s what I was just thinking as well, that it might be the CVT. I found a huge exhaust leak, which I’m currently uploading a video of, I got that fixed, and the good news is, my neighbors wot hate me as much whenever I start it up now, bad news is it still has the same symptoms. I bought a new cvt face, and will order the other parts I need soon. I was however quite disappointed when I tried to put the kickstart gear onto the cvt, only to find it rusted on there a few weeks later, I’ve tried everything from heat to prying, I’m gonna buy a hacksaw to remove it and bite the bullet on a new one. My main question now is whether an improper seal on the cvt cover could cause a loss in compression, or if that is unrelated? Cause I only have 2 of the cvt cover screws, that’s all it came with. |

Once you have the exhaust issue sorted let's see how it goes,the CVT does not affect the compression,you might get some bolts for it from a hardware store,I,m puzzled about the kick start post some pics before you start cutting!!!.
