Soooo,
I now have spark again - cleaned up the flywheel again and bright blue spark. Not sure what's going on though - I can only get it to run for 10 seconds or so before it backfires and dies. It starts pretty easy now but dies soon after BUT it runs quite well on just the rear cylinder with the front lead disconnected. Not sure what the issue is now but it's going to have to wait for another week before I get the chance to look at it again ...
Pete
