So was riding my 50cc Bintelli Scorch to work Fri. Wasn't having any issues at all,even with the free flow filter getting slightly wet from a misty drizzle. Pull up at work and proceeded to do my 9hr shift. Get off work at 10pm,after closing, to go and try to start my scooter...
Nothing... Nada...
Engine is cranking fine, lights are coming on when cranked, so I know battery and stator are fine. Just not turning over. Figured ok, maybe it got wet, so I stashed it in a locked shed at work and got a ride home. Come back next morning and get it out, and attempt to start it... Engine makes a pop like it's attempting to start, then back to the same thing as before.
Decide to push it home (close to 6 mile walk in 40F weather and was dripping in sweat). Get home, and try starting it again, spraying starter fluid in. Same single pop then nothing. Drained carb, checked plug, coil, cdi, adjusted valves, and still nothing. Plug is showing spark when out of the engine, and has compression, but won't just start.

Definitely getting fuel to the plug. Cranked engine a few times and plug was wet. Sprayed starter fluid in and got pop when trying the back to same. Kill switch was unhooked.
I had a similar problem the year I got it after riding in a heavy rain from a connection getting wet, but usually it started right up after. Now it's almost a week and not starting still

Well, I found the issue. I had one of those "performance" cdi units on the scooter (the blue one). We'll those units aren't potted like the others, in fact they only look like it on one end. The other end just press fits in to hold the sand (yes sand) they fill around the circuit board with. Well I didn't know it until I turned the cdi upside down, placing the bottom that's pressed in toward the ground, and saw water dripping out. Apparently water had gotten in through the cap they put on and had been soaked up by the sand. As soon as I drained the sand out and cleaned off the board it fired right up when hooked back up. Board in CDI: Close up of compnents: Quality manufacturing: The CDI uses the larger capacitor to fire the ignition coil. Well the wet sand caused this to short out with ground, not noticeable under testing with plug out.
