Holley stumble trouble

Oh I'm sorry. I overlooked that somehow. You might try a bigger pump shot. Normally, a bog is too much air.
I was tempted to try a bigger shooter but the next biggest I have on hand is a 37. Quite a jump from the 31 that’s currently in it. Besides, isn’t that just camouflaging the root of the problem? Not sure. Seems to me that the transition is lean and that’s what leads me to think I need to open up the idle feed restriction.
