40 hp Outboard Mercury Tracker 2 stroke Motor wont stay idling,it putters out & dies.

I just changed the water pump, then had to change the head cover gasket, and changed the fuel filter since it was old, yet when I start up the motor, I have to really throttle it up to keep it running. When I throttle it up it really sounds good and runs good.

This is a 97 Mercury Tracker 2 stroke outboard Motor, but It won't yet idle. When I try, it putters and dies.

Why is this? Bad gas? Carbon buildup?

Any help is greatly appreciated.

Thanks, Rob
