ok, i've been having trouble with the low end torque as some of you know. i've got the gap at and the plugs all look like this and my carb gets grimey (after what might only be a trip to walmart and back) and i clean it to look like this (carb cleaner) if i shorten the gap to .45 will that make the spark more potent? i'm running the DUI. what do you other DUI guys have your gap set at? i'm also always getting black exaust all the time.
