Default Re: Still getting really bad gas mileage.

If the spark plug is showing lean or normal it could be a miss at full throttle due to the poor quality stock plug.
I would recommend switching to a good plug and setting the gap to .024 to .026" and see how it runs before putting a leaner jet in the carb.
