"The rich spike stayed in the 11.8 to 12.2 A/F range. The 62 jets did not hurt my WOT A/F number, it was still at 13.0 at my shift point. It also took away from my low end power at WOT."
Can you explain what you mean by "took away from"? Are you saying that the jet change to 62s reduced the low end power? Was the AFR different after the rich spike clears? I would think that the rich spike is definitely impact power on the initial transition to WOT.
If the smallest squirter doesn't tame the spike some, I wonder if increasing the AP clearance on the secondary side only might help slightly decrease the total pump volume and the discharge onset.
