If your engine is running lean ( new carb, which may not be tuned or jetted correctly ) or if you have an excessive vacuum leak. It will run hot. Also if your initial timing or advance is not set, or working correctly it can also cause it to run hot. It seems like you may have a few interrelated issues that need to be addressed or confirmed to be correct.
