Gets hot and stalls out

Good afternoon everyone, have an update for you! I put the .25" carb spacer in today (and chased down a horn issue but that's for another post) and took it out for a quick spin. At 40 mph cruising speed the motor just touched 180* (83* and partly sunny weather). It idles at (what I think to be) a low 600 - 700 rpm when in drive, and 800 when in neutral. After sitting in the garage for 5 minutes the gauge indicated an engine temp of just below 195* and the car started with no hesitation.

Aside from the (again, what I consider to be a) low idle speed while in drive, everything went as I expected it to. The real test will be when it gets to 210* while driving, sits for a few minutes and then I go to start it again.

A lot more work to do but figured I'd report in!
