massive reconfiguration time again.

I think you are building up carbon is why the compression when up. 120 mile drive should help that a lot.
When I see the Speckles on the porcelain I think its detonation. Then I kind of looked in the cylinders with a flashlight and it looked like wet carbon.
Starting to rethink the timing. And now just remembered I'm almost positive I dropped °2 of timing with new cam. So that makes sense now why I saw °34 all in °18 initial.
I just started the motor for 30 seconds to get the oil pressure up because I knew I was going to turn it over a lot.
