China scooter

It´s fabric name is Jinan Qingqi and is a 50ccm³ scooter wich I bought 2nd hand for 100?. I invested some ? to get it in good shape, because the previous owner had an accident with it. It´s cheep on fuel aproximatly ~2l/1ookm, but it´s a hazord of thuning it to get it going propperly. Sometimes it lets me down after a journey, in wich I have to push it back home. Two days after resting it starts again for a new sort of push and ride journey!
