I would appreciate feedback from anyone who has encountered this problem or knows how to solve it...

Whenever my 400EX (2001) sits for a few days (cold or warm weather) and I go to start it there is a hesitation - almost like the carb is clogged. If I hit the throttle is stalls out...

After a few minutes it will idle and then run fine - I do not want to do any engine damage - any thoughts, ideas or opinions...
