So I have been trying to figure this issue out. For the past few days my scoot has been popping when I accelerate sometimes and dying at stops. The symptoms usually happen for the first few minutes of riding, popping is very minute, maybe a small one or two pops when I accelerate from the mid range to the high range, but never from complete stop. It happens less or never when I carry a passenger. It dies at stops usually for the first few minutes of riding, but starts up no problem.
I recently replaced the variator and I inspected everything and found my rubber ring on the intake manifold, engine side, was all torn up, so I replaced it with one from an old manifold I had, it was a little crushed so I decided to add a paper gasket in between the manifold and the plastic spacer. I tested for leaks by spraying wd40, no drops. I also tried to see if the engine would try to keep going if I suffocated the carb by blocking the air passage, but it died as soon as I covered the air intake side of the carb with my hand and I got gas all over my hand, yuck.
I checked the valve gaps, all still the same as I set them a week ago. I adjusted the carb idle mixture to get the smoothest best idle I could, about 1 and a quarter turns out. I checked the variator and everything in the CVT, all working good... Engine compression is good, it can blow my thumb off the sprk plug hole. Exhaust is all tightened down.
I guess my next step is to check all the wires for fried or loose connections... Maybe it is that idk what else it could be I'm really pulling hairs out here. It doesn't seem to leave me stranded but I know if I ignore it it eventually will...
