Sounds like you have an air leak, that jetting is way off for your mods...... I just re-jetted for the warmer temps and am at 32.5 pilots and 340 mains (ported 4mill on pump fuel)... I'm not too far from you.... I'm in Westland, Mich. Ave and Venoy area... If you can't get it worked out, let me know I can help you.
