I inherited a grandmother clock and it only works for a few minutes ?

you did remove the pendulum BEFORE traveling didn't you,? if not you have altered the pendulum pitch ,or your floor angle is different level/pitch to your grans, its so much easier to get a wall mounted clock going .yours will be trial and error of adding packing under one side of the base to alter the pitch from tic,tic to tic tock tic tock
