So reassembly.
In the pinion gear, the carrier needs one of these little spring loaded pins inserted, after some struggling I ground it down very slightly and a hammer completed the job.
Result.
Cover had me stumped, until I looked at a photo taken earlier.
The mesh spins on the inside, it looks so wrong.
.
And of course the scrap.
Good enough reason to struggle or fail to start.
So I thought I would chance it straight away.
See if it would start.
