I have put 850+ hours on my 912ULS since I bought it 4 years ago. This problem is new in the past 20 hours. The first start after sitting for 2 - 3 days it runs rough like one carb it not supplying fuel. It will run like this for 20 - 30 seconds then smooth out. It will not do this on subsequent starts the rest of the day. The engine runs flawlesss, good power, smooth so I don't expect it is anything serious, maybe a float seat sticking closed. 

My 100hr is coming up next week so I will be inspecting things very close. Does the group have any sugestions what to concnetrate on?
