Took tires and rims, front only back to have the balance re-done. Found a dirt dobber nest in passenger side rim, guy told me it changed the balance by 1 1/2 oz. Had them road balance them . Still haven't found any shop that will balance drum's, guess I'll get out the side grinder and do it my self. These drums have the groves on the outside ( called Lincoln style ) have lot of metal to work with. We've had 16" of rain in the last few days and mosquitos are really bad, have to wait a while to get back to work. Al
