What Mods are on my Jeep?

[Gdog]

Just converted to a 2100 carb, and I'm up and running again. Yippee!
Now I need to set the timing, but before I dig in to that I am hoping someone can tell me what modifications have been done by the PO.
Pics attached

I think it may have had the nutter bypass, due to the blk/orange blk/purple wires.

I also know that there has been an ignition and dizzy upgrade. MSD6 ignition, MSD Dizzy, and what looks to be an old coil, and a motorcraft clip. The clip has a crack in it, I discovered as I was about to install a tach to get ready to set the timing. Is this a must replace, or normal wear?

What I don't know is what was done correctly, and what wasn't!
Any help would be appreciated. Also if anyone has suggestions on things to look for after the carb conversion that would be great. Sorry for the 20 questions in one post, but I figured the more info on what was modified would help put the puzzle together.

Thanks,
GR

It may have had the Nutter By Pass. See if the wires spliced in by the coil go straight to the Ing. module. I would get rid of that plastic clip on top of the coil it is . I replaced my coil with a MSD coil with screw on connectors. As pic shows.

Thanks. Any advice on what I should ask for in the parts store. Is it still "coil for my 84 CJ, with screw connections"? or is should this coil be a diffrent size than OEM?
Sorry I know almost nothing, but I am learning (I hope).

I got it from Autozone it's a MSD blaster coil. It will be the same size as the stock one.

I was wrong about this the by pass will have two wires spliced in going from the Ing. module to the dissy not the coil.

Get the Blaster and get rid of the butt connectors and solder and shrink wrap on some good waterproof crimp on ring connectors , or corrosion will stall you out at the wrong time and place, nice dizzy.

X2 ...or roll your own connectors. When I did the upgrades in my engine compartment I had a lot of soldering and connectors to make



A friend from another forum turned me on to these compound crimpers that replicate factory crimps.





...to finish up I found this outstanding heat shrink tubing. This 3M stuff has heat sensitive adhesive inside. One it begins to shrink it becomes jelly-like and positiely fills every crevice. What's more those crimpers I got off EBay were cheap~no doubt made in lower slovobia but have served me well for these projects. For my battery cables (work in progress) I got a set of these hydraulic crimpers also made in lower slovobia for larger cables.





...this was first try and I didn't get the shoulders of the terminal over the edge of the insulation, but now I got it figured out and check that crimp pattern, this 2/0 cable is going nowhere.

Thanks all. I appreciate all the info and the pics are a great help. Once I get the 2100 running right, I think this wil be my next project.
I hope to have an updated with pics of my new coil soon.

it looks like an ignitor upgrade maybe Pertrornics? hot set up, what gap do the plugs have? i kinda like the plastic peice, if it was made better the idea is great.
