One other thing,my rev counter sometimes flys all over the place,I'm guessing its just a knackerd rev counter.Someone saw it once when i was driving the car and said the car was misfiring,but it felt fine to me,could it be a faint misfire,or is it just a dodgy counter like i think it is.also when i disconnect the king lead when turning the car over,it makes the rev counter flutter,is this normal,again i would assume so as the coil is doing no work,then when its arcing across ,in effect you are shorting out the coil,
