Narrative:

Delivery flight from pae to mco departed XA30L (PST) in ZLC area, given a heading for orl. Approximately one and a half hours into flight the autoplt kicked off and would not reset. Captain and first officer taking turns hand flying. Approximately three and a half hours into flight in intermittent light turbulence, aircraft climbed to approximately (according to center) FL333. Descent made to indicate FL329 and was advised we were again 'in conformance.' continued to mco. Corrective action would probably have been to request a block altitude due to difficulty flying (hand) the aircraft with the turbulence.
