A NEW timing issue

[jcelk]

for a test try a stiffer spring and see what the mech advance is then

I would check and make sure that the black bushing is seated and installed properly in the distributor and has full movement.
The springs only change how fast or slow timing comes in not how much.

I should also mention that it seemed like my locked out distributor was losing some timing higher up in the rpm as well (dropping a bit from the locked out 35-36), but I attributed that to the other issues I had with the distributor gear...maybe not?

Did you say you had some sort of Cam button installed?

That's the thing - I'm not sure there is one or not...I will be making a call today to the builder.
