Is it firing properly? Sometimes the connection between the battery and the coil isn't very good, try (very gently) prying the sides of the battery contact upwards... It does move, don't be too frightened but don't use a lot of force... I've just rebuilt you a coil anyway, I'll be in E14 during the day tomorrow if that's any good to ya... 1.76Ω and good to go!
