Thanks for the response! When I went to my LHS he sold me a HPI pull start but its like its just too small, and he doesn't carry any CEN parts, does anyone know any other pull starts that will fit, I have the .28 Corsa Engine. Also, I rewound my pull start but it doesn't fit snug anymore, I assume this will be a problem, the other thing is, when i pull the pull start some times it moves the cylinder, some times it doesn't. Its not like it was before, it used to have lots of tension on the rope when i would pull it.
