I have come up with a solution to my problem.. when my battery was at full charge everything worked fine... but once it dropped below 3.8 volts it would no longer retard the spark... not sure why???
A 4 cell nicad is offically empty at 4.4v, in other words even though the cell still has voltage it has no amps left. The low voltage also effects the timing chip.
WHICH is why the specs call for 4.8-6.0v for operation
