Huck's use of dialect in this excerpt from chapter 23 of "The Adventures of Huckleberry Finn" affect the story by lessening the tension in the story.
Huck uses language to create humor while describing how the townspeople are filing in to extract their revenge. He knows that they are carrying some king of weapons, but downplays it by saying that it was "no perfumer". Then, he explains that he smelled rotten eggs and vegetables and sixty-four dead cats, using exageration as a way of mocking the situation.
The expressions he uses heighten the suspense that is building as the townspeople file in to exact their revenge on him and the others" is how his utilization of dialect to point out the setting affect this part of the story.
