The fuel/air mixture unit is surprisingly easy to disassemble. Pivot shaft is NOT pressed in (air sensor plate counter weight does hold it tightly however -- loosen the two screws on either side, accessed from below). Then simply remove the snap rings and push it out with a screwdriver. Can extract the broken allen wrench, free up the CO adjustment screw, etc. This unit does need to be vacuum tight -- treat yourself to a new gasket from one of the vendors during reassembly. May as well replace all the O rings as well.
