Default Re: Jetting Adjustment for Sea Level ?

We use the 9636 Federal Mogul 625 cfm carbs, essentially the same components as your Edelbrocks. If the DA changes 3000 feet, rejet one jet size (ie 92's to 95's). If you would rather swap metering rods, a difference of .003-.004 in the metering rod tip is roughly equivalent to a jet change of one size. if you are borderline lead at 4000+ DA, and the air at Mission is in the area of Sea level or better, you would be safer by jetting up 2 sizes in the secondaries, and one size plus a rod change in the primaries.
