Default 1994 Evinrude 70 hp 3cyl 2 stroke

This motor runs great past 3000 rpm's, but at idle in neutral, and in gear all the way up to 3000 r's it runs poorly. I am assuming it is a low speed idle adjustment, but kind of lost on the procedure for idle adjustments. Spark seems good, compression is good, I just want this thing to run smoothly

Welcome to iboats.

It sounds like you need a carb rebuild. Pay special attention to the idle orifice/jet.
