Hello Sir... here you go.
AC-43.13-1B CHG1 pg 12-13 and 14
ref is made to CFR 14,23.1327, 14 CFR 23.1547 and the equipment or aircraft manuf.. manual... and... use a brass screwdriver to adjust the compass. And for tailwheel aircraft the tail needs to be placed on a "dolly" to simulate a straight and level flight attitude... although... if you cannot find a "dolly" the FAR's allow for your very best friend to place the aircraft tailwheel on their back to simulate a sawhorse
