I have a Sears Craftsman model 917.2884, 2008 model,this is very simular to a Poulan Pro garden tractor. I need to replace the clutch return spring. I know it attaches to the bell crank pully bracket , but I can't seem to locate where on the frame it hooks. The owners and parts masnual Sears supplied is of no help and neither is their service people. I cannot find any area that shows wear to attach spring .Can some one assist?
