Thanks for the replies. It's a speedfight 2 100cc. The scooter oil tank is disconnected and it has been run on premix before i got it. Seems to me like it was run with no oil before they realized and disconnected the oil pump... When I got it, the first day or two it did a 16 mile round trip perfectly "fine" albeit with engine clatter. So i took it to the garage, they fitted a new battery and must have started it as they said the clatter was the bottom end (no surprise, its clearly been abused with perhaps no oil at times) Since the garage returned it for me, It now won't kick start (used to kick start before if kicked lots and lots) and it sounds like this with a battery in it. I wonder if it's seized with the garage..... I don't know what to do now, as i was going to fix the bottom end so long as it was able to start nosily like before, but now it generally seems knackered. I know it's just best to scrap it now, but i was going to try and learn something by fixing it....may just not be worth it... do you think i should try much else? I
