210 isn’t that hot. Should keep running.
Lean carb and retarded timing can cause the heat.
What’s your timing like?
Do you have a heat shield between your carb and intake?

There’s a possibility it’s your carb. Here’s a big thread on hotrodders about the 670.

Are your fan blades half way inside the shroud?
