Same thing I did on mine, drilled to .120". .......I'll have to see if I can scrounge up an aux needle and seat to try. I typically run 7#, 9# in good air with just the one inlet, but I know when I jet it up in really good air,it tends to nose over at about 1200'.. .....You can see the A/FR go lean at that point,so the aux valve will definately help .....Suprisingly this is the most anyone has been willing to talk about these carbs. .....The few Ford guys who run them are usually very protective of their info. ........Tom
