    Here is another test sheet.

    I shouldn't have posted this one because it didn't have to do with the valve advancement problem. I just saw that it was a test of the RAV which I have not posted a picture of yet. Anyway, it shows some of the kind of problems we had testing.

    This is a test sheet on the D Konig we got from Marshall Grant. We were having surging problems with the motor prior to Phoenix. We tried everything. We even rented a D Konig from Jim McKean, but Marshall's old D was still faster even with the problems. As a last gasp effort we changed stator plates between our D and Jim's and that cured the problem. One of the brass posts for the points was drilled slightly crooked. When setting the points the double spring was strong, but when tightend all the way tension was taken out of the springs so that over 9500 RPM's the points on one cylinder would float. This test was with CAVIV, the last generation of the rotary valve advance mechanism that was part of the flywheel assembly.
