Is your engine basically stock? I had to detune my 1406 carb two steps to get it not to be rich. You can get the kit for about $30. It is real easy to do.
Now I am getting 15+ miles per gallon and pass the emissions with flying colors. Good luck |

With your carb you should have gotten a booklet. In that booklet there is a chart that shows you what needles and jets you need to tune you carb.
You can get the kit from either Jegs or Summit. Edelbrock carbs are real easy to work with. If you need to change the jets, it might take 20 minutes. Needles take less than 5 minutes to change. |

The chart in the booklet will look like this:
My carb is now tuned at the number "7" spot on the chart. I originally went with the number '12' spot, but it was to lean. |

Check out this page for the kit you want. I guess the kit you need is $20 more than the one I needed
