I shortened the original springs and tried again.  Works perfectly now every time.  I guess the originals were a bit stretched and the new ones are just too long. 

Thanks guys!

If the springs are too tight, the switch will not disengage, possibly burning out the start windings. 

Listen carefully. During startup, the switch should make a scratchy sound until the motor gets up to about 1/3 of its top speed, then get quiet. On shutdown, it should coast quietly and once the blade is about 1/3 of max speed, the scratchy sound should appear. The engagement speed is not important, just as long as the switch engages and disengages.
