need tuning help on 340

did some more checking today on my timing.when I set my total to 34 at around 3000 to 4000 rpm's my initial is at 22.I have my balancer marked at 34 for the break-in,so I could set it there at 2000 r's.At idle,that 34* mark is setting at 12* atdc.I rev the motor up to 3 to 4 grand and the 34* mark moves to 0.It seems that I only have a total of 12* in weighted advance in the dist.does this sound correct?:realcrazy: thanks.
