Thank's again for you'r input on my situation but I think I may have my problem resolved,you see the hose I have running the fuel through accidentally I put running over my fuel tank when it should be going under it,so I just changed that and also stuffed some foam around the carb. and took it to the field for a test flight and until now I do'nt get that problem anymore,and when I whip the throttle she accelerates just great with no hasitation,just exactly what I was looking for
