Had an early coil model on a K plate, and at night the dizzy lit up like fireworks night where the cap and plug leads were breaking down

Keep an eye out for smokey one's though, on the over run a number of them chuck out blue smoke.And you know what that means
Beware those with miss fires,theres plenty around !!
