I just purchased a 1974 vespa ciao with 154 miles on it. When i tested it at the guys house it ran fine, accelerated fine, and everything.
But today 2 days later, after adding some fresh gas and oil mixture i was riding, and got about 1-2 miles away from home and all of a sudden a loud metallic rattaling started, and the engine lost power slowly. First down to 20, then 15 then 10 then just shut off.
I'm new to mopeds, and need peoples help in finding out a solution.
