Cuts off at idle (video of offending motor included)

[Blue_Runner]

Thanks Ferm. Carbs didn't look very dirty to my untrained eye. Could fuel pump cause this symptom? I had a bad fuel pump when the motor was only a few years old, but that impacted my ability to get up to max rpm, not idle. I've seen at least one instance online (must be true!!) where a motor was doing similar to mine at idle and it was confirmed to be fuel pump(s)
