Your timing might be correct. If the motor is at TDC, and it looks like your rotor is pointing 15 or 20 degrees before TDC, that might be right. (I'm assuming that when you said "advanced" you meant before TDC). For example, the initial timing on my motor is set at 18 degrees before TDC, and, if I pulled the cap, the position of the rotor would be exactly as you described yours, so yours may be right.

As for the bushings and springs, you can buy a kit to recurve your distributor which contains new bushings and springs for less than $20. Unless you have other problems with the distributor (like worn busings in the shaft) I'd go that route before investing in a new distributor.

That's my .02


edit: I just went back and read the previous posts. The above assumes that your cam gear is set up properly. So get that straightened out first and then set your timing.
