How do I remove the needle jet on TMX35

[paulnobodyimportant]

Related to my earlier thread on my TS1, which is running rich, I am thinking of replacing old for new my needle and needle jet, thinking that these are not unlike the PHBH needle and atomiser.

So, how do I remove the needle jet on this TMX35 carb (see photo), or is it a permanent fixture, unlike the atomiser on the PHBH carbs. I say that because I’ve just found this on MB’s old web site “This carb unlike any others around DOESN’T use needle jets”
