1989 Evinrude 110 HP

[crestlinermusky]

So after acquiring this 1989 Evinrude 110 and finding out that I cannot swap parts to my 1975 Evinrude 115.
I was told when I got the motor that the rings on cyl # 1 were broken and that the cyl walls were scratched.
Upon careful inspection I can see that there is a new head gasket on the motor, when I pulled all the plugs and turned the motor by hand I heard no
noise from inside, I checked with an inspection lite for any scratches and could see none inside, I put it all back together and went for broke.
She started right away, low speed idle is rough, I am wondering if the cyl wall could affect that or if not running for two years would probably cause that.

do a compression test, if that checks good, clean/rebuild the carburators

A compression test would be a good place to start an assessment of the powerhead. Not sure why you would want to try to run an engine when the prior owner said the powerhead was severely damaged. Wouldn't it be best to pull the head and see just how bad the damage is? It's hard to make any condition assessment from the sound an engine makes when running.
