Gently insert them into jet (avoid scratching!) and confirm that mere 0.001" of clearance. You can now also verify needle type...it's embossed into mounting surface. The protrusion of jet of rear carb is keeping dashopt from falling all the way to bridge at idle...if you tried to adjust idle and mixture with jet in this position, I expect it would be damn near impossible! What I would do: Get both jets to be flush with their brass glans, then reassemble and tune...a "rebuild" is not necessary now that you've found and will undoutably correct the root cause.
