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.

yup def soudns like a carb job. make sure when you pull the low speed needles out of the carb that you screw them in and ount down so you know were to set them once you reinstall them
