Ruff at idle

[macojoe]

My 1986 225 hp Evinrude sees to run much to ruff at idle?? I mean my electronics even shake on the dash!
Just give it a little gas I am fine to go! I think my Tac is off by some? But it reads 900 at idle but then I get 6ooo at WOT.
I know get a good tac and be sure its right, But I don't have he cash right now, and I can tell right out that motor is not at 1000 at idle!
Starts perfect!! and all day its like a light switch!! you don't even hear the starter, Its Bam and its running!

So you think it just a idle higher or lower problem, or something else?

Thanks guys!

Going to bed now, up at 2:30 am for fishing!!
