Brian, by all means, get the S 100 dialed in before you add the Cline. Put 1 or 2 tanks in it before you adjust the low end to ensure that it is seated. Once warm, start to turn it in a little at a time. The general procedure is, adjust it in 1/8 increments, start and check. Repeat untill transition is satisfactory. If on a bench, with the plane secured, in the past I have set it with it running. Once your close to idle, turn it in when running untill you hear the idle raise and smooth out. This method is more dangerous and is not for everyone. If you choose the recommended procedure, its merely a process requireing a little patience and persistance, but well worth the time. Once you get your first gallon run through, it is time to set the rocker clearance. We could talk about that later. Joe
