First time posting here- lots of good information & knowledge on this forum. While trying to figure out why the deck would like to buck me off the seat besides the obvious of bent idler pulley arms & pulley bearings & possibly wrong belt, I checked the spindles for run-out, they both are out right at .010-.012, I know what this run-out would do to couplings & such, but what about this deck? What's acceptable here? Would appreciate any feedback on this.
