You are playing with fire here....if you run that engine lean, for just a second too long...it's gonna be a very sudden death for it, or at least one piston....the idle mix screws, if i'm not mistaken, should be 7/8th's turn out from lightly seated....but that shouldn't affect full throttle at all....without knowing your engine up close and personal...would follow the standard troubleshooting...use a portable tank to eliminate fuel restrictions, if no help then would check pulse pumps...carefully...what do the plugs look like? sounds like it's running lean...but hard to tell anything with so little information
