Just go my Mikuni BST40SS so-called Carb overhaul kit. Anyway I am looking at the rubber-tipped needle. On other carbs I have overhauled the needle moves up and down with float action. This needle has a pin on the top that moves - it's kinda like a plunger or somthing - when the float moves up and down it just presses on the pin (plunger) and it moves down. The old float pin-needle or whatever you want to call it I removed the pin (plunger) on top does not move at all (of course this may be why it was flooding all the time. Can anyone shed any light on this? I got no instructions with the ProCycle kit.
