1997 GTX No bottom end power

[Dr Quad]

Very sluggish on take off until I hit about 5500 RPM's and then it runs very powerful. Any ideas why sluggish at take off? The RAVE valves were cleaned before I got it, but I have not taken them off yet. I've tried to adjust them in and it didn't make much of a difference.

Be sure the carbs are clean and adjusted properly. Low speed screws should be at 1 1/2 turns out High speed "0". Be sure the accelerator pump is working at bottom end also. Have you done a compression test to see what the compression is? It ideally should be at 150psi.
