Others will offer better advice than I can, but might ask things like, does that background knocking change if you put your foot on the clutch pedal? But perhaps don't run it again until those more knowledgeable have contributed as you might get a 'don't whatever you do start the engine again' reply.
Enjoy yourself, it's later than you think!
