My MC-13-250 has problems

[cheapeto]

Man it's an 07 when scoots coming from China were very hit or miss. It's obvious the guy had problems with it,right out of the gate, low miles older scoot.

I would tear her apart, and retrace all my wires, double check/or replace all hoses, replace the filters, clean the carb, reset the valves, hell myself, I'd clean out the gas tank to.
Put in fresh oil and final gear oil, check your belt and clutch area, maybe blow out all the dust in the clutch.

Man, I really hope you did not get a lemon, but that time frame, and before, was very hard on china scoot buyers. I got one myself, but a 2008 150 retro.

Good luck, I'm sure some of the smarter scooter mechanics will give you much better advice then mine, but thats where I would start at.
