Some success, took the points off to give them a good clean, have the flywheel a bath at the same time. Refitted, set the points and ignition.

Next step to try the restart but will probably be the weekend.

Saw the rebuild kits but would also need the small spring as well as the valve. Someone has a valve listed on ebay for £25 which is a bit much. Supply and demand maybe..

If only I had a lathe... and maybe an annealing oven?
