I don't have too much to add to this one, but maybe replace the plug and check the CDI for cracks.

I voted help.

Welcome to the Forums Keefey94, now when you say the carb look immaculate can you elaborate a little? did you open it? did you run some seafoam on it? Has you scoter been in storage or stop for more than a month?

Could be a misfiring plug or bad coil... The coil may be on it's way out, and saturating. Both are cheap.

i doubt it is the carb....it is possible if you live at a different altitude than where you bought it or it sat for quite awhile and the carb got gummed up, and/or bad/old gas
