Re: sooty exhaust and lost power

...just a though on the soot... When I was dialing in my Carter carb on my 327 chevy, it would run rich. After about 5 miles, the plugs were sooty black and I lost performance. As it happened in a rather short trip, my mixture was waaaaay too rich. So see what the plugs tell you.

If you think that you are burning antifreeze, due to a head gasket, I would think that you will find a clean plug or two as they are being "washed" by the antifreeze. But I would think that you would see white smoke out of the pipe.

Check your oil too, but I can't believe that you've lost a gallon of antifreeze to the oil. It would look like chocolate milk, or thinner.

I may be wrong with the above, as I am only a backyard mechanic. Someone may correct me.


Good luck!
