Does your loadamatic actually work? If the vacuum can is shot you have no advance at all. This happened to me on a French motor which has vac only and that was broken.

It does sound like good, positive progress though.

Mart.
The weather on the way in was about 82* with very high humidity and the trip back was slightly cooler, about 76 with high humidity.

The vacuum can was originally destroyed when I first started troubleshooting the issue, so I replaced it thinking that was the source of my problems but it didn't make a difference. The new can holds vacuum for quite a while and I can verify it's advancing -- a little too much.

I believe the griffin cap is rated at 15lbs, so I'm not getting to boiling territory, but I'd definitely like to find a way to bring those numbers down and be able to go up a hill without keeping a nervous eye glued to the temperature gauge.
