Hi,
Firstly my dizzy had a whirring noise coming from it...then it started missing....opened it up and the rotor had a bit of play in it

the mechanic without investigating it further said needs to change the dizzy...is their anything we can fiz like a bearing of some sort ?
How can i check if i have internal or external coil if i need it replaced....dizzys are quite expensive in australia...!!! if i get a recycled part off a half-cut what should i watch out for ?

Thanks
