I figured out last wk that my Harmonic balancer is bad. So I decided not to trust the readings it was giving and to just retard the timing until it ran nice and wasn't pinging. I started with 8* then 6* and finally ended up leaving the timing at 3* according to the harmonic balancer. The Car is not pinging, running strong and idling much better than before. So I guess I'm wondering would it even run right if I was actually running 3* timing? Or is it possible I'm really running a lot more timing and the readings the HB are giving me are just that far off.
