Overheating during idle

Going to do the radiator have not rebuilt the carb.

Timing light is not working will get one this week.

What temp should I hope for at idle?

Not sure how advanced the timing should be?
Thank you

180 at long idle.

Sounds like you have tuning/timing issue. Is it fairly stock motor. Go by the book or don't run vacuum advance and set it to 34 degrees total advance at 3,000 rpm.

Having the radiator checked out is a great idea.
