I have a couple of 4611's but they were on the shelf when my garage burned. So a pattern starts to emerge, we have blue engine paint on 6/25 and 7/07, start searching for documents in that time period to see if there was really a TSB for the change...
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
