And for the uninitiated: the needle jets "tap" out from the main jet side into the venturi. Just remove the main jet and its brass washer, thread the main jet back in (without washer) and give it a (hopefully) gentle tap to start. An 1/8" wood dowel can also be used as a punch. Some pre-soaking in penetrant lube doesn't hurt if gummy in there.
