Those darn spacers can be a royal pain in the butt. I’m pretty sure the domed end goes in first, closest the fuel mixing pocket. Some guys put a few drops of Loctite on the outer diameter in the hopes the spacer will eventually stay put. I would thread the needle valve through the spacer outside the carb body just to make sure the threads aren’t messed up. I usually try to thread the fiber/packing washers onto the needle valve:
one plastic washer/2 fiber washers/another plastic washer, then thread the needle valve into the spacer and insert the whole mess into the carb followed by the packing nut. Don’t thread the needle valve too far through the spacer, you don’t want to accidentally jam the tip of the needle into the mixing pocket.
