Howdy, Thanks for the reply.. It is a 1979!!!!

Hi Everyone, I am new to this post and hope you can help my 14 yo stepson. He just bought for $100.00 a 1979 80cc Enduro. I know nothing about dirt bikes or motorcycles but I am pretty handy. The bike is in reasonable shape for 100 but no back brake and if it kick over is does not stay running. I ask him what gas/oil mixture he used and he said 53:1, No one told him that he just used what his buddy uses for his new bike. What is the proper mixture and is there a place I can get a service maual for this. I was going to take the caeb off and clean it out but thought I should get some advice first. Thanks for any help Regards, Ron
