I have a 1989 Chevy 5.7 liter 350 on my boat and at idle speeds it makes a tink like sound and a thud at the same time. Also the motor shakes a tad when this occurs also. Opinions? It also has a rich gasoline smell to it too and is hard to restart when hot unless you give it some throttle. On a cold start it fires right up within like 2 seconds. It doesn't seem to do this until about 15 minutes in once it's warmed up. It also has a bit of vibration when this occurs and feels sluggish.
