My 360 Engine is running reverse once turn off.

Curb idle rpm too high and/or overheating. I recall some 4 cyl. having anti diesel solenoid on the carb. One that would push the throttle to wide open at switch off.
Reverse rotation is not good for worn engine parts. Run hot, turn switch off, engine turns backward and timing chain jumps, valves get bent. Bad day. Such was the case of my AMC 232 6 cyl. Ran very hot while crawling along to parking spot At Carowinds Park. It was about 10:30 pm when I found out we had a problem.
