1996 Sterndrive 4.3lx 6cyl. 4 barrel carb with Thunderbolt ignition.
At idle, wot and everywhere in between it runs fine. The problem I am having with it only occurs when I turn it off. With the key in the off position, it keeps trying to run. Not in a smooth way, the engine kind of coughs, hiccups and jerks at times up to 15 seconds before it finally dies. Is that a gas or timing issue? What are some reasons for an engine to start dieseling. A couple times out I noticed a strong gasoline smell after filling the tank. I inspected the lines but couldn't find any leaks. I'd appreciate any advise I can get as to what I should be looking for. Never ran into this before with any motor.
