This pull start is compatible with Motovox go-karts, and mini bikes like the MBX10, MBX11, and MBX12. In addition, this popular pull start will work on most other mini bikes factory equipped with 80cc or 97cc 2.8 horsepower (hp) 4-stroke engines.
It may be tricky to replace the string as there are springs inside the pull start and the proper tension must be reached. We'd recommend replacing the pull start outright for the simplest and easiest fix.
