Of course Simon, I think you'll see the
page in italian, I recently moved to Italy and that's why I buy from Amazon Italy haha. Anyways, you can just look on the web for a mechanics or automotive stethoscope and you'll find plenty of models, this is also a great way to diagnose rattling manifolds or bad bearings or any similar stuff.
Anyways, getting back to my issue. What would be the worst case scenario in my case? What if the flywheel gets worse and gives up completely and for example it breaks or wobbles too much around? What would be the worst effect it can create?
