Just a quick question I would like some clarifaction on - Someone once told me that if your carb was under sized for your set up it could result in the engine running hotter than normal.

I have ran everything from a 600, 650, 750 and 850 cfm carbs on my engine with no change in engine temp. That's not to say if it is not jetted correctly it will run hotter.
A carb that's undersized won't make anything run hot. And like the other's have said, a too lean carb could make it run warmer. A too small carb will simply act as a governor and limit the engine's top speed. Ask the boys in Nascar, they've been subjected to restrictor rings under the carbs for years, which in effect acts to limit the cfm going into the engine.
