the 3rd pulley, the one that moves when you move the speed selector is the tightest when the selector is in the slowest position. according to the speed indicator next to the lever. also the belt was installed correctly according to the chart for the mower. The belt I purchased from jacks small engines online so i would think that it is the correct size for my mower/engine combination. I will take a look and see if the trans pulley is messed up or anything.
thank you for the reply
