I got the Screach. I hope it's not contaigous. Installed new autoclutch. Seems to work fine. Do Whizzer belts all do this? I have the belt tensioner installed & both front & rear look good. Both even & tight. Up a hill or just wide open throttle with a load will CRY LIKE A LITTLE GIRL> The front belt has been suspect but I tryed 3 different ones & She"s still whimpering. What can I do?
