Long time away from the board. I am thinking of having a local machine shop bore out a spare si24/24e carb that I have to 26mm (and to drill the fuel supply hole to the main jet to 2mm).
I am not sure what it is called -- the brass tube in the carb throat -- spray bar, something like that? Anyway, how can that be removed? I grabbed it with some small needle nose pliers and pulled but it didn't budge and I was worried about squashing the tube.
