        Yes they will drill out easy...EXCEPT you can mess up the threads in the friggin needle jet!!!!!!!

        Heres what you do. Heat the crap out of it with a propane torch...short of melting it..and dunk in cold water. Do this 2 or 3 times. The heat and immediate cooling will crack all the oxidation that's locking it in.

        Next apply penetrating oil. Find something that will grip the inside bore of the snapped off jets threads and CAREFULLY try to extract it. I suggest a very thin blade flat tip screw driver first. If that wont start gripping the walls of the threads, then move on up to an EZ out. But be careful and apply twisting pressure evenly. If the EZ out still wont budge it, you may have to replace the needle jet and the main jet.

                I am guessing all of you are referring to the EMULSION TUBE when you are saying "needle jet"? Just trying to give you the correct terminology in case you have to order parts. Ray.

                  Actually we are referring to the needle jet...which is its proper name.

                    Went and got my manual...seems both our recollections are wrong Ray. The manual calls component number 15 ( 1000 VM carbs schematic) a "breader pipe". See section 8 under the disassembly of carbs part. Schematic list the "emulsion tube" and what I have learned as the "needle jet" as a breader pipe. We are both incorrect in our terminology.

                        My apologies.
                        I thought he had CV carbs?

                          What does it matter..its the same part..no??? Does the same in each carb..no? So the manual calls it a breader pipe..no? Am I missing something after rereading the manuals description?

                          I will go look at an 850 carb manual to satisfy my curiosity though.

                            CVs are called a needle jet according to the manual..its the 1 piece unit. Apples if its a VM carb and oranges if its a CV carb I guess.

                            But nowhere does it get called an emulsion tube.

                              VMs have an actual needle jet separate from the tub the main jet screws into, whatever you want to call it. Little tiny thing way up in there. Completely different from CVs.
