I just had a starboard engine rebuild done on my 2000 410 da 454 mpi. Before I had this done the sync gauge would give me a steady reading with little effort. Now with the new engine the sync gauge is a little jumpy, especially over 3000 rpm. Can't get the gauge to stop moving even when I feather the throttles. Does anyone know what could be the problem? Thought after I popped for a new engine my problems would be over.:smt009 And the throttles are not lining up very well on the way up. Any help would be appreciated.
