Will the new car Angkewei run 1.5 thousand kilometers accumulate carbon?

Hello, there will be carbon deposits on both valves and throttles, but the carbon deposits formed in1.5000 km can be ignored and need not be cleaned. You can wash the throttle after 30 thousand kilometers. I hope my answer can solve your problem. Have a nice trip!
