Wet Black Soot Exhaust

[bk53]

i had that till I blew the carbon out of her. rich idle condition contributed greatly. Ken ct rebuilt the carb. It was after that the soot quit showing up. I do run 100 miles a week at highway speed, 60-65. as for the water you can put 1/8 holes at the exhaust low point etc. but I'm not seeing that either anymore and I didn't drill the exhaust..
