Hum.. could be the issue. I did richen my mixture and that had only a temporary effect, but I'm not sure that the heat was not just a coincidence.

I took my somewhat more modern 1972 140 out on a night *much* colder than today and had no issues at all.

Also, these problems got worse and stayed worse *after* the car had reached operating temperature and stayed poor even after I pulled off and let it warm up. Based on this experience, I can't say I see a clear correlation between perceived carb cooling the poor engine performance. I will say that at least to a point, the performance problems were somewhat like the engine behavior when you start it cold.

I do, by the way, have a one-piece cast-steel combination manifold as well as the lower front carb shield in place.

Since I cleaned out the molasses (Mobil1 back in december, I've only had Marvel Mystery Oil in the dashpots... Still quite slick in the 20s...

High-powered 1800E fan and shroud, maybe a thermostatic-switch controlled electric fan would be worth the investment...
