thanks for the suggestions guys,took it apart and discovered that my tension was way to tight.i rechecked the markings on the belt with the pulleys and read the book again on how to check the belt tesion and than rechecked for a third time ,put it all back togather and it runs nice and smooth.took it out for a 30 min. drive and it still runs smooth,so i guess i got it right this time.
thanks again
