Bermuda Moped 1977

I have owned this Bermuda moped since new. It was used in the summer at my country home, but has remained in indoor storage for the past 4 years. There is no rust and looks great. I started a couple of weeks ago and it ran for 20 min then stopped. The carburetor probably needs a cleaning. I believe it is made in Holland. It is a C class so it does not require a license or insurance.
