A ruff idle will not be caused by a fuel pump unless your fuel bowl level is too high and fuel at idle is just dribbling out of the boosters in the primary side.
You would see sign’s of wetness in the throttle bores in this case, and as long as the carbs accelerator pump is working good then on the other side of the coin you have plenty of fuel in the carb to idle off of.
Those sintered metal type fuel filters can pass a lot of crap due to how pourus they are.
So yes, you might have a partial of fully clogged metering passage that’s needed for idle.
