I am the proud new owner of an 89 Stratos 289fs/200 Evinrude. I've fixed the usual wiring problems(caused by previous owners brain malfunctions), De-carbed,synchronized throttle linkage,new plugs,new impeller&gear oil,new fuel filter &oil pickup filter/screen. It runs good to start out with, idle is good, jumps up on plane,runs 62.5 at wot (gps) for the 1st run 10-15 min. After restart when I give it gas it acts like it's getting starved, like my old 79 Johnson did before I rebuilt the fuel pump. Local dealer says to replace the vro unit ($268 just for the part). Where should I start to trouble shoot this? I haven't been able to get the tach to work the wiring seems intact the gauge has power and ground, I did have a burned up yellow wire in the juction block I replaced, and it seems ok now. Any guidance would be appreciated
