85 century no RPM's

Help!!!

I have a 1985 Century Mirada 25' I/O. The engine sounds absolutely great but the problem is I can not get the RPM's to go over 3200 therefore I can't get up on a plane. I have changed the prop to a 19 pitch, re-built the carb, changed the cap, rotor and wires, and adjusted the timing all to no avail. I have an alpha 2 outdrive and the engine is a 350 v8. Any ideas??? I'm stumped.

Thanks for any help

Low rpm

I think the engine is aged.

Check compression : compression = hp.
Might idle poorly at low idle as well.
