That's really nice, but dare I say the heavy plug lead detracts from the delicate appearance? Is it worth looking for some thinner fibreglass sleeved HT wire that you can screw to the top of the plug?
Neil thanks for the comments. I agree it looks a bit "out of scale". I think will have a look for an alternative and have toyed with the idea of an electronic ignition as I'm currently using a 12v coil and micro switch as a contact breaker.
