Sounds good. I'm finding some mis-information, and a lot of posts on the 2A page have broken links/pictures.
I was having trouble getting my timing set correctly, and when it was set, would backfire under heavy throttle. Prior to this it idled a bit rough, but ran decently. One of your posts here gave some good things to check, and my igw 4177-1 seems pretty worn out (springs and bushings). Going to try the electronic version from Omix but again haven't seen much about it. Lots of guys like the Pertronix, but with my worn out distributor I figured I'd give the Omix unit a try.

A word of advice. If the shaft bushing is worn nothing you put in there will work correctly. For a little more than the price of the Pertronix, you can have that distributor rebuilt to factory specs. Then and Now is the place to contact. I and many others have been satisfied with their service and pricing.

It's got a chunk missing out of the side of it too, so I had planned on replacing it. Any idea when Jeep used the IGW 4177-1? Bruce Mullen (cj2a page) picked me up a new body but it was for a 4008. My motor isn't original though (U stamp).
Thanks for the link. I'll see how I make out with the electronic one, it'll be here tomorrow. I did get the points set correctly and measured it with my Dwell meter though, but once you said about the shaft wear I and I saw the springs I figured I was done for the night.
If your dizzy has the condenser mounted externally and the body looks small then yes, it would be a correct early model for the VEC, column shift CJ2A. The 4008 series replaced it and is probably the most widespread and used model for 4-134 motor.

Thanks for the info - mine's a 46 (12275) that was originally column shift, but was converted to floor shift. T90's date is 52. Bellhousing has a F stamp, so does the dipstick. Jeep stamp on the engine though, no ribs, was pre PCV too. There's definitely a story in there some where.

I'll take some
Replaced the dizzy with the Omix unit, and new plugs/wires since the old wires wouldn't fit correctly into the new cap. Installed, aligned the timing marks in the window, checked compression on #1, and installed 1,3,4,2 based where the rotor pointed and it started right up. Checked timing with light (I have to use #2, or #4 plug - to see the timing marks) and set it to 'IGN'
Runs pretty smoothly at idle (~650), but still backfires at the carb under quick throttle. If I goose it some it'll do it without it.
Carb I rebuilt a few months back, and it's adjusted with the screw 1.5 turns out. I set the metering rod using the dial indicator.
I've not checked the valve tapets, but it ran decently before I started this. Any suggestions?

If I set the timing where the vacuum gauge stabilizes between 20-21 hg, it's better. I am advanced well beyond the timing marks in the window though. Still backfires a bit. It will not though if I choke it slightly, but at that point it will not idle.
