Zackybilly, for what's it's worth, I ended up reducing the mains on my FCRs from the 152s they came with to 140s. Raised the needle clips a few notches as well. Here's what I ended up with (copied from another thread I participated in a while back):
Needles in position #2 (were #5 originally).
Slow fuel screws 2/3 turn out. I was getting some popping on the overrun at 1/2 turn, which 2/3 has mostly eliminated. I think a little
popping on especially "violent" overrun is a good thing. Could be wrong...
Slow air screws 2 turns out
Replaced main jets (originally #152s) with #140s, down from the #145s I had done last time around. Still seems not too lean at WOT, so all the better. May try 135s, but I think I'm close. (Note: I never did try the 135s. The 140s seem right.)
