i have been having trouble with a viking 36 scalping . the dealer raised the blades all the way up inside the deck. it did seem to fix most of the scalping but the cut isn't exactly the best and it still scalps randomly. any ways i was just wondering if this set up is correct for this machine ? exact set up is ... 3 spacers on the front casters back axle set at C or D i forget < the machine has been in the shop for 2 months but thats another story> and the blades raised completely up into the deck , 4 spacers above i believe.
