I'm pretty sure I know the answer, but just in case.
The kickstarter shaft is sheared on a 'new' 65cc Dynamo Compact I recently bought.
I have a replacement, and it appears the cases need to be spilt to change it.
BUT- is there possibly a way that pushing the appropriate drift through when removing the old one that it could be done without splitting? It almost looks like it is possible in the manual.
I have a spare engine around- so I could test it, but if anyone knows I would appreciate it.
