A good indicator of how lean/rich your fuel mixture is, as wheelbender6 said, is the spark plug. You're looking for a tan color around the center electrode. White is too lean, black is too rich. This was my plug at 4,500 miles, back in Aug of 2014.....put it back in and ran it to 12,000 miles. Replaced with a new one late this spring.
