It sounds like this all started when you did your tune up so perhaps it's not the carb.
Did you set your points by gap or do you have a dwell meter?
Are the plugs gapped correct?
have you tried pulling the plug caps off one at a time to see if you have a cylinder thats not firing?
Spend the $100 and put a pertronix and coil in it!
If you want you can drive it over to my house and we will put a meter on it and check everything out.

FWIW I would stay away from Pertronix. I had that in Jessica's blue bronco before I upgraded to the DUI cap and it gave me nothing but trouble. I had the ignition and their "flame thrower" coil. I will admit that I upgraded to the DUI at the same time I installed a Centech harness so it may have been other electrical gremlins causing my issues, but they didn't come up with stock equipment. Just my 2 cents.
I agree with Bill - check the gap in the points and plug gap. Are all of your wires nice and snug (good "click") on both ends? Did you use dielectric grease on your wires - I always do but too much isn't good.

Holy cow George.
Is your choke hooked up backwards somehow?:rubeyes:
That's just the opposite of what should happen. When you pull the choke out
it richens up the air/fuel mixture and your saying the fumes get less? Push
the choke in (lean) and the fumes get worse?
Perhaps your Bronco went through the galactic plane and now it's an opposite ocnorB.
I'll have to think about this one a little more ....

You can get fumes from an overly lean condition, NOX fumes. A lean condition could also cause the loss of power or lug. When the choke is closed raising vacuum through the venturi, more fuel is drawn.
You can let the engine idle with the choke off and take a folded towel and cover the top of the choke horn with the towel and your hand trying to shut off the air. If the engine raises RPM before shutting off, your mixture is lean. If it just sputters and shuts off, your mixture is rich.
Did you check the float level with the guage when you rebuilt it? It sounds like it may be too low.
