CONTINUOUSWAVE

I left the engine throttle [for a 1996 Evinrude Ocean Pro] at wide open for a week after checking compressions. Now [the throttle] is stuck and the culprit is the timing base plate. How freely should the timing base plate move with the engine not running?

Any tips on repairs?

Thanks Phil

I'll offer some uninformed comments, since no one else has jumped in:

--the timing base is moved by the throttle lever linkage, so it should be quite easy to move it; the force needed should not be any greater than the force exerted by the throttle lever linkage;

--my off-the-cuff suggestion: disconnect the throttle lever linkage and try to move the timer base by hand; perhaps some corrosion developed in the week it was left in the full-throttle position, and the base is stuck in place from that.

Again, this advice is just seat-of-the-pants advice. Perhaps a real mechanic can comment.
