My advice, Since you asked. I would pull the engine and remove tins to clean. Very critical part of maintenance on these machines.
As far as it taking a long time to start.. This could be fuel related. Even if its not I would suggest a thorough cleaning of the entire fuel system.
Welcome to OCC and good luck with your machine.
BTW.. we like pictures here
