50cc 2 stroke engine pull cord won't retract? HELP!!!?

well this has happened to my mate twice and we tried every thing and we thought the best thing to do is buy a new one because when you take the casing on the inside of springs and wires and every thing that is in it will just shoot out so if u want my advice replace it its cheap on ebay only about £9.00 last time i looked but that was weeks ago so dont know what it would be now just make sure you get the right one because my mate got the wrong size twice and just ended up paying alot of cash so my advice is buy a new one of ebay or go to busters in swansea if your in the area or off roader in ponty
