I just purchased one of these Suntune CP7602 units on Ebay. It is perfect cosmetically, but I am suspicious of the accuracy. The low RPM setting shows about 800 RPM, but the High RPM setting shows about 2000 RPM. I do have it on 2 cycle mode and then inductive clip is the right direction on the top spark plug wire.

Any thoughts if someone has experience with this same unit?

I am trying this on an Evinrude 15024 18HP from 1958.

Sorry for the double posting...I also placed this on the Evinrude board as well. Not sure where it belongs.
