Hey gents, see the attached. I believe the starter jet is not removable. If this was clogged I assume it would not allow the bike to start. What's the best way to make sure this is not clogged. Carb cleaner, compresses air, god forbid a paper clip

Should you be able to see light shined through it?
Any advice on this and how it functions would be most appreciated.
