New to the forums due to seeking help with my Chinese scooter. A while back my left brake lever stopped turning my scooter on while pressing the electric start. The brake light also would not engage when the lever was pulled back. So, I began using my front brake lever to start the scooter, which worked fine. Well, I had some recent problems and I recently had to replaced the CDI and Electric Choke because my scooter was having problems starting. After the replacement, everything was working perfectly. Sounded great, started up on the first try within the blink of an eye. I ran it all day the day I got it fixed, even turned it off and back on and he started up just fine. Took him out again the next day and everything was fine, started up etc just fine. Later that day as I went to start my scooter back up after having it off, I noticed my front brake lever was not turning my scooter on, I wiggled it and moved it around and finally it started. Now, the rear brake lever nor the front will start the scooter. It's turning over, has spark, good compression etc. My battery is good as well. Also did a valve adjustment not but a few days ago before I had got it running. Good oil as well as good gas. My front brake lever still engages the brake light, but won't turn the scooter on. It also will not start with starter fluid. I was told that the switch in the brake lever can keep the scooter from starting up if it is out or needs replacing, and won't even start on starter fluid. I'm by no means a Chinese scooter mechanic so I'm not sure. However it was a Chinese scooter mechanic that told me this through a friend over Facebook in a scooter group. My lights and such turn on when I attempt to start the scooter up, turns over, sounds like it wants to start even, a little more so when I twist the throttle, but it just won't get past that point. Any help is appreciated. I really want to get back out and riding.

All the brakes do when you squeeze them is send VOLTAGE to the SOLENOID and the Brake Lights that is electrical that squeezing the brakes do. Then while holding the brake you push the START BUTTON all that does is GROUNDS the SOLENOID to complete the circuit and the SOLENOID then sends 12volts to your starter.
1. When you squeeze the brake either one do the Stop Lights come on and push the start button does it SPIN YOUR STARTER?
2. When you squeeze the brake either one do the Stop Lights come on and push the start button does it make a clicking sound or nothing.

Only my front brake makes the brake light light up. When I pull in the rear brake lever, it doesn't make it light up. When I pull the rear brake lever in and try to start the scooter, nothing happens. No lights, no clicking, nothing. When I press the right brake lever in, lights, and it turns over and sounds as if it wants to start.

Ok cool your brake left brake switch is either bad or wire came off.
But at least you have the Right brake switch that is still working.
Now did you add anything to the scoot, different carb, Air Filter or take it off etc.. How many miles on it and when was the last time a valve adjust was done?
Also you can try turning the Fuel ratio mixture clockwise until it stops then turn it out 2 1/2 turns and see if it then starts.

Nothing added to it, did a valve adjustment a few days ago before I had got it running again. It has a little more than 5k miles on it, close to 6k, and okay I'll try that.

Your scooter was having problems starting so you replaced the electric choke and CDI then it worked again but after two days stopped working again. I'd suspect the CDI or electric choke you just replaced and/or the wiring thereof. And being that the break lever switches and their wiring are also electrical, I'd fix them too just for good measure.

Sooo do you have any suggestions? There a way to test these parts to make sure they are working before chunking them or buying new ones, again and or so I can rule this out?

I just don't want to have to buy new parts again with the chance of that not even being the problem. If there's a way to test these parts though..

![]() I've looked and looked and looked and there is no such screw on my carb. If there is, it looks nothing like this and isn't even located in the same spot from what I can tell. |

I'm no authority on such matters but I am a trouble-shooter by trade so when you say that your machine worked after you replaced those two electrical componants, but now it doesn't work again, I immediately would suspect either the componants you just put in or the wiring that goes to them. A bad wire connection could look like a bad component so I would start with looking at the wire connections. And because you also have an electrical issue with your brake switches, I would find the cause there too. You'll never know if the problem at those switches is the root cause of your problem until you repair them. The possiblity exists so you should rule it out if you can. If you rule out enough things, whatever remains has to be your problem. You verified that you have spark at the plug? And you have gas, and air, reaching the cylinder? Then it should start, or at least try to start. Maybe it's just flooded with all the starting attemps that you've made? And, the screw is probably on your carb but is just hiding behind a cap and/or plug so you can't mess with it. The manufacturer doesn't want you to mess with it. But if you insist on messing with it, pull your carb so you can find it and drill out and pry off the cap and while your carb is off the bike crank it over a lot to clear the cylinder of gas in case it's just flooded. But I'm no authority on such things. I just felt like writing a bunch of words.  |

No where did I say you did not know what you were talking about? You clearly should understand, since you know what you are talking about, correct? That these things give constant problems and surely you would know how frustrating it is when you go to at least a dozen different sites and forums and facebook pages asking for help and no one seems to be able to help me solve this.
