I'm not familiar with these carbs and I've just got one to use on an RB kit. It doesn't appear to have an idle / pilot jet fitted just a B type emulsion tube, size 40. Should it also have an idle jet sat above this? The emulsion tube is recessed so there's room to fit a 5mm idle jet above it. It's recommended to use a 50 idle jet so should the emulsion tube also be a 50?
Cheers.
