BEFORE you start hosing with your timing setting, I'd either confirm the balancer hasnt slipped a little and/or make a scribe of where your dizzy is in relation to the lower intake.
If your HB started to slip, the timing light will mislead you and where you think your timing is set. Having that initial reference will allow you to get back to where you are now.
Good luck.
