You could have stripped the threads out on either the bolt, or the nut. You may have to replace the cable assembly back there.

I don't know what you mean by hang, but I haven't noticed any issues with it.

I had made a post earlier about my disappointment with the torque spring. As is the case sometimes, it was operator error. I was not adjusting the variator weights, and when I installed the torque spring, my rpm were getting above the sweet spot. You have to adjust by putting heavier rollers in to compensate.
I installed rollers that would keep my rpm at slightly below 6K. Then, after installing the 1500 torque spring, my rpm would stay at a steady 7200. I compared this to rollers coupled with the stock spring that kept my rpm at the same 7200, and the 1500 torque spring gave better acceleration and hill climbing. The torque springs affect acceleration a little differently than rollers. This part is definitely an upgrade. If tweaked correctly, you can achieve noticeable performance upgrades with this relatively inexpensive part. I should have given this part more of a chance before I poo-poo'ed it earlier.
In my constant quest for 60mph out of a 139qmb, I stumbled upon the right setup for the torque spring that I had written off for dead. Next up, when I get the money, the high dollar performance clutch.

I am a curious guy, sorta like our ole' pal George. I have noticed something about these things. On the 8 pole stators, some have 2 ignition coils, some have 1. They will both work fine, as I have used both in the past, on the same scooter. Is there any advantage to the one with 2 ignition coils? With 1 ignition coil, you have the advantage of another coil dedicated to lights/charging. Anybody know why some have 1, and some have 2?
I recently changed over to the 11 pole stator, and I highly recommend it. My kick-starter is broken, and until I get the dough to order a new one, I am running 2 batteries on my scoot. That 11 pole stator charges both of those, no problem. It charges at roughly 14 volts at idle. I have no doubt it could keep 3 charged. I initially kept my original R/R for charging, and used a 7 wire one as a DC converter for lights, but Jerry told me that was unnecessary, and he was right. The old 4 wire R/R would charge at around 13 volts, which isn't good enough for 1 battery. The 7 wire rectifiers are SOOOO much better, so thanks Jerry!
I ran all new wiring. Got different color 16 gauge from the autoparts store, and cut the connector off of the stator, and used bullet connectors. Same with the rectifier. Just cut the connector off, and used bullet connectors. I can disconnect them, and reconnect them as I please.
Anyways, I kind of digressed. I was curious about the reasoning behind 1 ignition coil vs. 2 ignition coils. Also, there are a few different kinds of 6 and 7 wire rectifiers. The 11 pole stator is 3 phase( you can tell with a wire tester), and IMO, when paired with a 3 phase rectifier, gives you a much better source of DC voltage, and does a MUCH better job of charging your batteries.

You have to make sure you have fuel and spark. Remove spark plug, put it back in the boot, and touch it against the engine to ground it, while turning the engine over. You should see it sparking.
Also, make sure you are getting fuel to the carb.

I would just order a new carb. They are only like $25. Screw all that. Just get a new one you can adjust.

Should be easily fixed with the air/fuel screw. Just follow Jerry's instructions.

That's a lean condition. You probably have a vacuum leak somewhere. You can use a can of WD-40, and start spraying your intake and hoses while it's running. It will bog when you spray the leaky area.

These things come leaned out stock. They do that for emissions, and gas mileage. I would up the jet. Do you have a tach on it? What RPM does it run at? As in, what RPM are you at between 20-40 mph? That will give us an idea as to whether to get heavier, or lighter weights.
Up the jet 5 at a time.

Have you adjusted the valves on it?

The enricher lets more fuel in when the engine is cold. It turns off via power from the engine running. The power melts wax, which turns off the enricher, so it leans the idle after about a minute or so. I agree with what Jerry said, about the idle screw.
Did you take the spark plug out? What do you mean black with a white core?

You got the right part, for sure, and that is all that matters. You did good.
When my frame broke, it broke right next to the shock under the seat, so I tried to just swap out the handlebars, and instrument panel from my broken frame to the new one. But, when I inserted the handlebars, it was notched differently. when the front tire was straight, the handlebars were turned all the way to the right. I couldn't get the shocks out of the tripletree, for the life of me. So I cut a new notch with a dremel, and off I went. But, it was a pain.
My point is, it is very nice to be sure you got the right part, which you did.

You could have found that tripletree on ebay, but that does you no good now. Roketa, the brand, is just the plastic farings. The frames, and engine parts are all shared by various "GY6" models.

That needle adjustment may make a small difference. But, it really only makes a difference between 1/4-3/4 throttle. If you are like me, and run WOT pretty much all the time, adjusting the needle won't really do much. I doubt you will be able to tell a lick of difference from adjusting the needle.
I would recommend you get some rollers that are a little too heavy, then get the 1000K clutch torque spring. That will give you better acceleration between 15-30. I have been tuning my CVT forever, and had been disappointed in the clutch torque spring, until I hit on that combination. I put 6.5g sliders in there, that are a bit too heavy, and keep my RPM at about 6000. Installing the torque spring keeps the RPM at about 7200(I put the 1500K spring on, but I wish I had put the 1000k on), and I hit the sweet spot. The torque spring seems to affect the acceleration a little differently than rollers.
I think you would be happy with that combination.
