If I press down more than 1/4 throttle engine stumbles and shuts off

I wish I could get the results these guys are having... however the guy that used to work for Holley makes me worry... then again, there's so many people happy with their TA470 on 258ci or other 6 cylinder, I tend to think I can get this kind of response from mine (not just the idle response, but when he's giving it half or more. )

Not sure if I can send links or not... about to find out. Lol

About to start reassembling my carburetor now. Cross your fingers for me!

All that took realize my main jet isn't squirting. Pretty sure it hasn't been now that I'm thinking of it.
I made sure every passage was clear in the main body and metering blocks. A bit frustrated right now. Would love to know why they aren't squirting.

I'm Jeff, jeeps Carl

I'll try to a answer all questions, but I'm not home so. You know how it is. I promise I won't just abandon you once I get a good result. You know about it too!

I already know a lot about mr. Jeep and willy from several of your posts/responses to others.

Even I said the carburetor isn't squirting I was referring to the venturi booster on the primary side of the carburetor. The squirter, shooter, nozzle. Whatever you wanna call it in the accelerator circuit is functioning. Properly? I dunno. Was thinking today I should drop it from a 35 to a 28 or so. Still undecided. Thoughts? (I know you wanna check several things first. No problem.)

After reading through some of the link you sent, I think I may have my timing 180 off.

Distribute vacuum was ported, until reading your posts. I've been using full manifold since. Unhooked and plugged during any adjustments or setting timing.
Vacuum advance is working. I used the good old "milkshake" method (if ya catch my drift) and it moved easily. The central. No idea how to test it.

I have an electric fuel pump on frame near tank. Noticed a small kink in lines but I don't think it'll effect flow (fingers crossed, but I'll get a pic later. )
The mechanical is still mounted to the block, untested.
Currently only have a 2 port fuel filter and return line is dangling (& in BAD shape) new 3 port filter and return line should be here Saturday.

As far as the "nutter" I'll uncover the wires and get you some pics of them too.

I think I've answered all your questions, but I do everything from my phone, so scrolling back up is a bit of a pain. Feel free to point out anything I missed and I'll get it answered.

You usually ask about some tools. I don't have a dwell meter, I have a tach gauge that I hook up under the hood, until he's good, then I'll put in the dash. Have a non adjustable timing light, leads on my multi-meter recently broke ( cheapy Harbor Freight one) have most other basic hand tools and not afraid to use them and get my hands dirty. Why would I be here otherwise! Hahaha

Lastly, don't worry about your country-fied language. I'm an okie. If, by some off chance I don't understand I'll tell ya. Besides, I usually have a lot of typos. Feel free to point them out if it's hard to read.

Thanks, Jeff

Pictures as promised.

While I was unwrapping wires from the distributor, I noticed a black wire that was disconnected. It turned out to be a piece that was spliced into the purple wire. The orange, black, and green (from coil) all go into the ignition module. Also there was a single wire with a butt connector coming from the ignition module. It appeared to be either dark blue or purple, couldn't really tell nor could I get a decent picture without removing stuff.

I guess my question is: should I reconnect these two wires? The diagrams I found weren't clear enough for me to determine and I don't wanna mess anything up.

Also, I noticed a section of orange wire that appears to have touched the exhaust manifold. I believe it's visible in the pic with several butt connectors. I'll get that repaired and fix up the connections. (Need to get a soldering iron.)

Is there anything else jumping out at you that needs attention or any additional pics needed?

Carl and I will be here once you're able to reply.

I took the distributor apart a week or so ago. Decided I didn't know what to do, so I reassembled it. Nothing appeared broken, but I didn't know what I was looking for.
I'll pull it apart again tomorrow evening for pics. (Too dark to do anything right now.)

Glad yours is working fine! & By glad I mean jealous. Lol!

By the way, how are my pics working for you? Any tips or anything I can do to improve them?

Glad to hear the pictures are doing their job.

Steve! If it wasn't for you I'd already have Carl at a mechanic and would've have found out so many things about my jeep. Can't thank you enough man!

The guys on this site are awesome. The more posts I read the more I can see that.

I'll check the coil itself to see if it has that statement on it, while checking the other items tomorrow. In the meantime...

Here's the coil I have on right now:
https://shop.advanceautoparts.com/p/accel-super-stock-coil-8140/5024269-P?navigationPath=L1*14923%7CL2*15034%7CL3*16064

Today, I rewired the 3 wires from the distributor to the ignition module, keeping as much of the old wires as possible. I removed the melted places and previous connectors. Started him up, brought up to temp. No changes. That's ok, it's beer thirty.

Now on to the requested testing:

Voltage at coil on positive side is 7v. Is this lower than it should be? (I know it shouldn't be the full 12v)
Btw, negative battery cable disconnected, gave a 12.8v reading. Random test while I had the meter handy.

Fuel pressure at carb with ignition key on was 9-10lbs (with a slight leak at my meter)
I'm guessing I should get a regular with the new return line installed?

Attached are a couple pics of the mechanical advance, looks fine to me. But again I dunno what it should look like. Thoughts?
Last pic is my pickup coil plug/ connection. Could this be causing an issue or is it something to cleanup later?

Your turn, my friends

1 1/4 turns in, each side. Backed them out to the same position.

Regulator installed, currently at 6 psi at idle. (I know it's a little low, factory setup and I haven't adjusted yet).

Everything still acts like it has.

Oh, I also pulled my fuel cap to make sure I didn't have a vacuum on the tank. Looks like my vent (or the open return line) is working. No, I haven't got the return installed yet. Honey-do's.

You responded while I was under the hood. Lol

Lol, I have that download to my phone, for that exact reason. However it never hurts to double check, so I will.

Quick question. Am I supposed to use teflon tape or something on the regulator connections? (They're screw in connections. I'll try to find a link to the part, so you know what I've installed.)
