I don't know why you think you need to carry your old lost-and-found passport. Carrying it is not a problem, but chances are high that you will run into problems if you try to use it for anything meaningful.

Interpol operates a 'Stolen and Lost Travel Documents' database, to which currently 174 countries deliver data. Your old passport is probably recorded in this database. Many countries check against this database on a regular basis when verifying foreign travel documents and if you try to use your old passport at a border crossing or during an in-land id check, chances are real that a red flag is raised and that it will be an issue that you are trying to use a document, which has been reported lost.
