I'm having a hell of a hard time with this thing - it's my first moped, and it's never idled right.
When I first got it it wouldn't stay running without choke. I replaced the air filter and I've taken the carb out twice now, cleaned it, soaked it overnight and got it clean as a whistle. It will run without choke now, but it loud and idles super high.
No amount of idle speed and mixture screw adjustment seems to help, but maybe I'm just not understanding how to do it correctly. I've tried checking for air leaks as well by spraying carb cleaner all over, but I'm not really sure if I'm hitting all the right spots.
I'm just completely stumped. Any insight as to what I can/should do would be a greatly appreciated. Here's a video of what it sounds like right now:
