Throttle response is great when the engine is completely cold, or fully warmed up. But theres a brief period of several minutes in between when there is a noticable hesitation off idle.

I'm guessing this is the warmup regulator going lean too quickly. System and control pressures are good, though I had to knock the pin down a little to get the cold control pressure where its supposed to be. Where else should I be looking, or should I just leave well enough alone?
