Evan,
it is very important that the clock is level or it won’t run at all. Start with leveling the case such that the pendulum is in the centre and does not touch any part of the frame by placing shims under the case. Then you will have to put the clock in beat by placing shims under the mechanism in the case. Listen to the tick-tock and make sure the tic and tock take are the same. If not place shimming under one side and try again, if it is worse you had the wrong side 
Normally when the mechanism is level it will start working.
It does look very pretty indeed.
