Exclamation weber carb jets

I have a 1988 yj, 4.2 with a weber carb stamp with an 11046, the jets are 50/75. I know that I need te bigger jets but I don't remember the sizes, and where to get them.

This is basically an Edelbrock.
Read this: http://www.edelbrock.com/automotive_...ers_manual.pdf

This is a primer for rods/jets/thresholds.
You need to run richer or leaner, that is why you are posting, right?

This is a 4 barrel carb on a 2 barrel right? With spacer and converted?

That's what I'm not sure of, I know its a 2 bbl, but I don't know the specifics, I talked to a couple real mechanics in town, u know the ones who have been around about 30 years. They told me to go atleast 3 sizes down since were at over 4k feet, and the carbs are set for sea level, u need to go 1 size down every 2k feet, and I do go into cloudcroft which it about another 4 or 5 thousand feet up. I can't find jets for it yet though, I even tried the weber site, didn't have anything like it.
