That article was really good, but your situation with already using an electric pump takes away much of what the article covered. I use only an electric pump as well. I too use my 901 in southern weather ( SC ) and seldom drive it if the temp is over 85. When I do, I get that same 180 temp which I do not like. That is a good way to blow a head gasket, something none of us wants to experience. My car usually runs at the 165 prescribed by Packard. My car too has the shutters blocked open for max air flow. If the situation only happens when the engine is hot, or the ambient temp is above 85, then I would look to your gaskets. It does not take much loss in vacuum, to show up in performance. Check the intake manifold gaskets when hot, also the carb gasket. A small leak can cause this and is the cheapest easiest thing to trouble shoot. I find most times a simple fix is the ticket. I don't like the diesel fuel thing, it is more snake oil than anything. Use non-ethanal gas in the 90-93 octane range if you can find it. I find that my car starts and runs much better with it.
