starters from napa, do you think they are just giving bad starters. They work great for a few weeks and then they start to make a little noise, like they need to be shimmed until they just dont work any more. I tried to shim it but it just makes it worse. If the flex plate is cracked a new starter would sound just as bad wouldnt it? Is it possible that instead of shimming it I might need to go the other way and grind a little off? Thank you for your help on this.
