I pulled the carb out again and messed only with the plunger thing. Sorry, don't know what it's called. I made sure it was clean, and tried to make sure that the diaphragm was stretched into the groove as the cover went on.
Still having the same issue, and like I said, I can put my hand over the air intake horn and it totally solves it.

Unless you've got another thing for me to try, I'm going to order a new plunger/diaphragm from ebay and wait to try that next.

Putting your hand over the air intake is manually choking it (less air, same amount of fuel). Did you move the choke lever before attaching it to the carb and make sure the plunger end was moving when the lever moved? Every Rebel I've had didn't like to have the choke lever moved at all except for gradually pushing it off as the engine warmed. Mess with it, either more or less, before it warmed up, and it would die. I did have one that didn't need any choke in warm weather. But it would accelerate fine without it, and yours isn't doing that. Here's what the plunger looks like: https://www.ebay.com/itm/1996-2016-H...oAAOSw4DJYiMTB

Yes, that's the part I was referring to, just forgot to add the link.

I suppose you could try the brake fluid trick on that diaphragm if it is too small to seat properly.

Keepin' all the left over parts. Gonna use 'em to build another bike!

The choke behaves as expected during idle but doesn't seem to make any difference to the problem when accelerating.
I found that if I mess with the throttle for a while, it appears to eventually accelerate better, but then when I put it in gear, it can't pull the bike. Idle pulls the bike strong, but as soon as I open the throttle, it can't and wants to die.

I also confirmed that the plunger doesn't move at idle or high rev. Is it supposed to go up and down at different times? I feel like I had it working for a moment earlier when the idle jet wasn't working, then after messing with the slow jet, now the vacuum plunger isn't working.
I have to stop for today, as I'm leaving town for work for the rest of the week. I ordered a vacuum plunger on Ebay, and it also comes with another new slow jet, main jet and some other pieces.

The first time I tore my carb apart for cleaning, I failed to properly connect the end of the enricher cable. It behaved much as you described.

Could you describe any more specifics for me? As far as I can tell I believe it’s connected correctly, so if it’s not, I would like to know what I could be doing wrong.
Thanks!

This shows how the choke cable end, part 12, is assembled https://www.cheapcycleparts.com/oemp...31c/carburetor

Before attaching the cable, be sure the plunger end moves with the lever. The plastic fitting on the end of the cable is theaded into the carb carefully by hand - dont cross thead it - and then lightly snugged up. Too much force can crack the fitting.

It's been awhile, but I think I didn't have the cable end on the lever properly, and when I tightened the plastic nut it just mangled. I ended up replacing the cable. They don't last forever.
