Rebuilt 216 engine still being set up and timed, had cooling problems before but corrected them. Now, some year later the engine is suddenly running hot, and boiling over. Still working to adjust the carburetor but out of no where I note the overheating, Nothing else has been changed on the engine so what is causing the overheating problem? Some mentioned that the head bolts may need to be re torqued and another mentioned that the radiator cap must be a 0 lb cap, mine is a 4lb cap. Please, your advise is greatly needed.
Regards,
Dave
