I rebuilt this motor some time ago, but yesterday was the first chance I had to really tow something. It was a 5000lb 5th wheel. Well, the EGT's ran at about 1000 degrees and it had a really hard time maintaining highway speeds. I set the pump loke the manual said, but with the high exhaust temps, doesn't that mean that the timing is too far retarded? Here is a picture of the marks.
Can I safely bump the timing, and if so, which way do I turn it?
