My pull start has locked up/ failed... so i decided to pull it apart to see if i could fix it...

on taking off the screw the whole thing exploded.. great... bits everywhere..

now my question is... i've found the coil, string and the main plastic unit and a spring... am i missing anything else... i got the pul start working again but putting it on is going to be a problem... as i'm not sure where the spring goes.. and i think i'm missing a piece of metal.. so when i pull the start it turns the motor over...

can anyone help.. please... i'm a desperate man... lol

i think the spring goes in the hole, in the center of where the coil raps round...
