Possibly teaching my granny to suck eggs, but if you’re using your degree wheel on the timing shaft, have you allowed for it running at half speed?

"Static ignition timing adjustment for the 250 singles equipped with the most recent pointless CDI"
With the aid of a piston stop and a timing whell, find the crankshaft's T.D.C. position as precise as possible. Then, block the crankshaft in the 54° before T.D.C. position (angles for 350 and 450 given below). In this position, the edge (1) located on the rotor must align with the little notch (2) on the stator plate. In case of mismatch, rotate the pickup stator until edge and notch are aligned.
