Mains too big, PVCR too small. Get the size from the body with number drills (the blank end!). The idle rich may be a throttle blade angle/position thing, float slightly high, idle air too small.
Note: all the ratio numbers are not intended to pass emissions, or be chemically correct - they are to save the engine long enough that you can tune it leaner slowly for best results. If the manifold mixture distribution is excellent the final WOT numbers will be closer to 12.2-12.5.
