problem solved
float ok but carb and petcock assembly very dirty. also the on/off/res flow was not turning off and. i cleaned the assembly and filters also cleaned carb and bowl. the gasket behind the selector for on off res had a small cut in it between two of the holes. i flipped the gasket over and tightened the spring plate up by increasing the bend just a little. a little o-ring lube and replaced everything and all is good... went for a short ride in the royal blue area ( TN ) and had no problems.
