Yes I did not change my fuel filter as soon as was recommended and one day it would not idle.
Sure enough looked like filter had let some dirt pass soooo, had to take carb apart and clean. Still need to adjust the mixture screw a little but will wait till I need to service spark plug since it seems you can't get to that screw without removing plastic.
Don't try to save money (or get lazy on that filter). Maybe the alcohol in the fuel destoys these faster.

how often is the recommendation?

EMCO fuel filters do have a problem with ethanol... the glue dissolves, I have read.
But a dirty fuel filter should not allow dirt to pass through, it should result is a blockage of fuel and poor engine performance.
So, I'd say that your dirty filter did result in bad idling but the dirt that got to the carb probably passed through the filter even when it was clean.
Just a total accumulation of very fine dirt or gasoline residues. It is best to buy gas from stations that sell a lot of gas and therefore have fresh gas.
And Cheapest gas may not be clean gas.
Shell gas seems to be the best for our bikes & scooters... even if their ecology issues are the pits.
scoot safely,

The owners manual shows to replace at 4300 miles but I agree it did look like the glue had dissolved some in about a year ( and 4935 miles). So I would replace once a year even if you did not have the mileage.
It is a little long but I made a purolater F21124 work. It was about $5 at the auto store.
