My carb on my 510 has a little problem. It idles fine, it revs up fine if you just floor it. The problem is it has a "flat spot" about half throttle in the 3-4K rpm range. If I keep my foot in it and accelerate through the gear, it runs great. Its when I half throttle it or let it run at a steady rpm that it starts sputtering and bogging down. I can floor it when it does it, and it will kinda sputter,then start to pull normally. I went through the carb and cleaned the float bown and stuff, and blew out the jets, but its still doing it. Any help would be appreciated it. The carb is a downdraft Holley Weber.

Thanks
