I'm betting it is either the condenser or the coil. 2cents worth. Dave

Here’s a video of what it’s doing.
Yes yes I have a water leak from the thermostat gasket. Lol.

Take that feakin air cleaner off so it gets more air and so you can see that the choke is open. See if there is any rev difference. Better or worse.
If no change then use your hand as a partial choke, or the choke lever, in various amounts of close-off and see if anything changes.
If none of that produces, get a spray bottle of gas and, between mist and squirt, it down the carb throat with one hand and throttle it to see if you can maintain that rev up.

Yes, I had the air cleaner off this whole time. I just cleaned it and wanted to see how it looked on the carb. The engine was warmed up and running with the choke wide open. I will have to spray some fuel down the carb and see how it reacts. I will let you know. Thanks for the help so far!

If the squirting has no effect, go to the electrical list above.

Well?

Re: Engine dies under load.
 

Ok. New condencer, no change
Points gapped within spec
New coil, no change
Re checked the carb float level, no change
Re checked the power piston no change
Installed the factory gas tank, no change
Removed the fuel filter at the fuel inlet of the carb, no change
Played with the timing on different °‘s no change.
With the choke fully closed, it will rev perfectly
squirting gas down the carb it revved perfect but would back fire a bit here and there. I did not get a chance to take it for a drive as it’s been raining for a few days here.

It's kind of good news it runs. Probably eliminates electric if you have it timed, points set and condenser is actually good. So keep that in mind as we move forward. It now sounds like a vacuum leak, kind of a big one. You said you did ether and it responded. Better investigate ALL hoses, fittings, lines, gaskets and report any messing around you did recently.

Not to repeat my self but back a few post ago I said "What you did with ether is a sign of a vacuum leak. Identify exactly where it is leaking by using a hose on the ether stem to keep the spray controlled". ..............I kind of like repeating myself. It's sounds so good.
