      A:

      Initial suggested settings for spark plug gaps are: Single plug : 0.028 - 0.032", Dual plug : 0.025 - 0.030". Spark plug gap should be made as small as possible, while still maintaining performance. A wide spark plug gap can cause hard cold starting, misfires during rich or lean fuel conditions, and reduction of upper rpm range.
