Yes the white/red wire is the same I took it apart and visually checked it to be certain. Here are some pics of the stator and the plug in end of the wires coming out of the motor from the stator. You can see the 6 wires and where they are connected at the stator, the blk ground is screwed to the plate that holds the stator in. There is a place where the red arrow is pointing that has a bare spot where the plastic has rubbed the inside of the magneto and metal is showing. Don't know if this is a problem or not. I tried the wire change that you suggested and there was no fire.

JR, This is the wire that we left unhooked. I know earlier that you said the red/white wire could be taped off, but did you mean white/red ? because thats what was left and looks like in the pic that it maybe should be hooked up some where. Did we maybe leave the wrong wire from the stator unhooked ? I have been thru the carb multiple times, rejetted to an 84, tried every needle clip position and tried every where from bottomed out to backed out till it would not run with the mixture screw. I have made major improvements. It starts with the touch of the button, idles great and can now take some throttle but still won't take it and go. Could this be a timing issue involving this white/red wire that is not connected ?

Thx JR, I will get one today. I got to looking at the carb and found that the needle and slide were assembled incorrectly, I fixed that problem and had a little better luck. Getting closer all the time. One day soon I will have her purring for me lol.

JR, yes I checked all the holes and they are open.
alleyoop, Q1 the scooter does not have an air filter, the people that had it are looking for the air box and other missing items for the scooter. Q2 I have not changed the jets, they are the original jets. Vacuum line is new and dry. The fuel mixture screw is flat on the tip but appears to be that way from the factory. It's tapered with a flat tip. I tried to take a pic but my camera just wont take a close up of something that small. The needle guide is installed correctly. And yes I took the jets out when I cleaned the carb. The carb is made in Italy. It is a Dellorto, it has PHVA 175 embossed on it and 1389-D7 stamped on it.

Alright JR, you are the man. I wired it up like you said and it starts and runs. It ain't ride-able, it has a serious bog when I try to give it gas. I have taken the carb apart and cleaned it . it runs the best with the mixture screw almost all the way in, but still can only take a little throttle before it goes to bogging. We have tried it from seated to backed all the way out till it started dieing on us ,and still can't get it to smooth out and take throttle. Any ideas what to look at next ? I checked the auto choke and it does push the plunger and needle out after being hooked to 12 volts for a few minutes. Damn the bad luck. so once again I am begging help. And I want to thank you very kindly for all the time , effort and help you have been. I was completely lost without your guidance. Maybe with your help I can fix this problem also.

Here is the way I think they hook up. CDI :________Stator :
RED/BLK ------ BLK/RED RED/WHITE --- WHITE/RED ORANGE ------ RED/WHITE BLK/WHITE --- COIL + BLK ----------- COIL ground
This still leaves the RED/WHITE wire from the CDI. I believe this to be the running lights ? And if it is , where will I hook it up at ?

Can You please explain which wire will hook where on the new CDI ? I know by the pic that it only has 5 wires and the old one has 6 as does the stator. So once again I am going to need your expertise.

There was not a ground from the engine to the frame , so I used a tiger paw on my grinder and took the paint down to clean metal and added a ground. But it had no effect on the weak spark. .

Ok I did as you suggested above with the wires and had nothing, put it back as before and back to a very weak spark. Not enough to fire the engine.

Ok I unhooked the orange wire and had no spark, not even a tingle when I put my finger on the plug. I took the coil off and sanded the paint down to bare clean metal. I then put it back on and reconnected the orange wire. yes it did spark ever so slightly, had to turn out the lights to see it, I did the touch with finger test, still just a tingle. I then unhooked the orange wire again and had nothing. So I reconnected it and got my little bitty spark back. Put the plug in hooked up the wire, I then shot a little starting fluid in it and nothing not even a pop. I guess there just ain't enough spark to ignite starting fluid. I also checked the plug wire and it looks good to me. And as far as I can tell the 2 wire connector has good contact.

I put the new coil on today , hooked it up , grounded the plug and cranked it over to check for spark . I thought I could just barely see a very weak spark , so while still grounded I put my finger across the gap touching both sides and tried it again. Yes it definitely had fire. just a tingle , and by no means knocked the shit out of me. My confidence was not very high. I put the plug in , hooked up the wire. Shot one small shot of starting fluid into the intake (carb was off) turned the key on , had a wire tie on the brake lever , bumped the starter button and I'll be damned if it didn't start right up. So I put the carb back on , pulled the gas tank , emptied and rinsed it with some clean gas , reinstalled and filled it with fresh gas/oil , hooked up all new hoses , primed the carb and filter , cranked her for just a little and again she fired up. Took it for a test ride down the alley. It actually ran pretty smooth , but didn't want to take throttle , the more I twisted the grip the more she bogged , so I rode it back to the house (100 yards) again it ran ok as long as I didn't give it more than just a little throttle. So I started adjusting the carb and had it revving lots better , but when I shut her down to an idle , she died and would not start again. I knew I had some carb issues but I did not believe that was why it would not start. So I pulled the the plug , again I touched and grounded it and cranked it over, I could just barely feel a tiny tingle. My brother came over and he retested every thing you had us check before. All checks were good. The kill button was acting kinda funny. I had to place the button in a certain position , which was just off of being fully detented and in what appeared to be the outside kill position in order to get it to spark earlier when I was testing the plug for spark , I thought it was just some of that crappy Chinese wiring and switches I have heard so much about. So we took it apart and had a look. Its a funky switch (3 way that slides back and forth with detents in each position). by the icons on the handlebar control cover , it looks like the outside 2 positions should be kill and the inside position should be run , but It is the opposite , maybe Chinese symbols are different than ours. My brother didn't fully understand the way the system works without tracing out the wires, and he wasn't up for all that tonight, and this part of the wiring was not touched by the dumb ass that chopped up the harness to start with. After reinstalling the kill switch , and making sure it would still tingle my finger , my brother checked the voltage at the spark plug wire , the needle barely moved. Talk about bummed out , holy crap what a let down. So any way I'm STUMPED again. JR , I need some of your guru magic that justbuggin2 was talking bout earlier in this thread lol. This thing is killing me.

Any idea about the NANFANG ? its metal and the actual Variator cover mounting to the case. the yamaha is a plastic cover mounting with two screws into the metal one
