Hi Deejay, thanks for the reply.

i will have to get this converter program(and idea?) as i've sort of kept a pic diary in case i get into trouble. Ive had a little trouble with my subs to get the manuals and as yet its not quite sorted out. I did notice that sprocket but as i haven't seen a new one i wasn't sure about the wear. I need to get an overview of the motor to understand what everything is called and where they go.

Do i need a bearing puller to get the starter case and flywheel off? I don't want to break anything!
