Does anyone know the correct method for removing the needle Jet from a Mikuni 24ss carb as fitted to Yamaha DT125 LC 1. The Haynes manual shows that it drops out through the bottom some  web sites say it should be punched out through the top ? 

I"v always tapped them out the top,  once the main jet is removed,,,.use a pencil,,,,   &   tap it on the bench,

My carb is a VM 24 ss or Yamaka code (10 V00). The jet neck diameter (top) is narrower than the jet bottom diameter. I would presume that it needs to be driven down rather than up ?
