No problem.
Remove the finger guard as described above and you should be good to go.
The pellets may play an issue (not sure on their diameter) but more so with the finger guard in.
This is how the burn pot should look.
The grate in the burn pot can rust out over time and you will see that happen between the slots.
The plate on top of the burn pot should sit in such a way that there are not gaps at the front and rear and the slide should look like it does in the pic.

I have the GEN2 EX4 and have removed the finger guard, ramp in the hopper and put a hose clamp on the glow plug.
I use it 3-4 times a week and have done so for the 17 months I have had it.
I use Weber pellets and have never had an issue of any kind. No flame out, glow plug failure, nothing.
The longest I have cooked on it was around 12hrs and all I did was check that there were enough pellets. I didn't stir them or anything.
Now, other people's mileage may vary but this shows that you don't have to babysit it at all if you set yourself up for success from the beginning and realise that the SF is not like any other grill out there.
I thought I was right about the "whump".
Don't don't bother calling Weber as recommended previously.
The person who suggested that can call them if they have nothing better to do and want to see how good CS is.
