Yep, the one on the valve cover side is a fatty.

Dude...Slow down and take a breath. Buy Redline Weber specific jets most likely from online source or from Redline directly.
That is if yours is a true Redline Weber Carb. Some of the Webers out there are not made by Weber. In that case, I would try to get my money back.

I've either gone full-retard on you (which wouldn't surprise me) or someone fubared your carb. This exploded view doesn't provide much clarity because it shows the same jet prefix number for both jets but does clearly state that there is a large and small jet holder. The jet links also show primary and secondary. Exploded view.

My 32/36 idle jets are definitely two different sizes.

Ya I did a little more research, some of the Original Webers were BOTH the small idle jets. Bummer but in theory I just need a 75 secondary idle jet in my primary...who knew. Ill be sure to follow up for others.

The other awesome thing I did was I rebuilt the carb while I was waiting for the new 75 jet. And I was blowing out passages and SHOT one of the emulsion tubes clear across my shop....CANT find it anywhere. So I need a new one, what size ? I DONT KNOW! hahaah man oh man. Heres the thing, Im sure this came off of a smaller car, so now on the 258 I probably need to swap ALL the jets and emulsion tubes to larger. Anyone have a full setup of what sizes work on the jeeps? Ill need Main jets, Idle jets (75/60),air corrector jets and emulsion tubes?

Your jetting will be largely dependent on elevation, and the condition of your engine. What works for Vinny down in Florida, will run pig rich for Wayne in Colorado.

You should be able to get an assortment in a jetting kit, then just experiment. Many of us like the F7 emulsion tubes, but jet and ac sizes will vary.

Air-launched an emulsion tube, huh? That sucks.

If it were me, I'd leave the existing a/c jets in their current locations but use an F-6 in the primary side and an F-7 in the secondary. You might have to drive-test it for a bit to see if the primary side wants the F-6 over the existing F-50 but I suppose it will.

I can't remember a good starting point on your main jets, however. What are they now?

The "Remaining" Emulsion tube is an F50 the other is somewhere in the space time continuum. Main Jets are 140/140 and the air corrector jets are 170/160. My elevation is 2700' high desertjust incase eithje rof you guys are similar.

And a picture of the Idle Jets/holders. Same size, weird huh? I inspected where it threads in on the primary side half expecting a "modification", but it's definitely stock from weber.

Whoa..sorry for the GIANT picture, I resized it in half, guess that's not enough lol. So at the bottom of the page on http://www.carburetion.com/diags/3236DGAVDiaginfo.asp it shows the stock setup from weber, which matches mine perfectly.
