How do you perform a link and sync on a 1988 25Hp Evinrude? I know where the adjuster screw is on the rod and how to move it, but how do you know when it is set properly?<br />Thanks...<br />P.S Just wanted to let everyone know that this site is amazing, I'm an auto mechanic, but the 2 stroke outboard stuff is really new to me. I've had a boat for 2 years now and this site has answer many question for me. Thanks
