well the smoke maybe from things out of the exhaust, you said it was sitting in a feild or what not for awhile, may have some creature nests in there.
proceed with the filter changing and rev it.

Black smoke is usually carb.....however, if it sat in the field too long, you might have a bunch of carbon scaling off the rotors now that it's running....MMO time? Or that Seafoam stuff....either way, you've prolly got a bunch of it in the cats killing exhaust flow...the engine can't breath....

to be safe and simple. drop the exhaust, its kinda easy, 4 bolts before catty converter, be aware they maybe rusty and break off, might need to replace em. but drop it and start it up.

lol....they ALWAYS say that....I swear, do a search with "exhaust no power" if you don't believe me....there ain't no piston and closing valve to ram rod exhaust flow...the overlap on the rotary means exhaust pressure can play a DIRECT role on intake flow...

I have to assme you've changed the air filter?
Does the fuel tank "whoosh" when you open the cap after you've been driving it?
(clogged up charcoal canister, the system can't breathe correctly)
Do a search for "Float Bowl Solenoid" and "picture".
A diconnected float bowl solenoid means the carb can't vent, and it can cause everything from complete leaning out to a siphoning effect (flooding).
Does the inside of the carb look dirty & brown?
You could have junk in the "Emulsion Tubes"...these are jets that incorporate air into the fuel as it enters the carb, but most importantly, they bleed off the fuel delivery a bit at higher rpms. If they are clogged, you again have the siphoning effect.
Dowse the inside of the carb with carb cleaner and leave it alone for an hour or so.
Then put goggles on and blast the hell out of it with compressed air. (You won't hurt anything.)
Make sure nobody has his face near it when you start it because there's a chance of backfire through the carb with that stuff.
BTW, your tach needle doesn't bounce around, does it? (That's an indication of an ignition issue.)
Your cats are probably clogged now with soot. Even when you get this resolved, it'll run better, but maybe only 90+% what it should due tothe crapped out cats.
Maybe someone knows what he can do to try to save them if they are only clogged with soot vs truely melted?
If you need to rebuild your carb, don't be intimidated. Everyone here can help, and once you do it you'll shrug and wonder why you were worried about it in the first place.

When you are changing the fuel filter, remove the bolts holding the fuel pump mount to the bottom of the car. Let the pump kinda hang down, while supporting it with one hand. Have a clear container under the fuel line coming out of the pump, and have someone turn on the key. You may be surprized at all of the crud that comes out.
I just done this to a 79 last week that had been sitting for a long time, even though it was started on many occasions. I think 2LBS of crud came out of the fuel pump, which suddenly started sounding much better, and supplying enough fuel to actually drive the car. Before, it would idle fine, and even rev up good while sitting still, but we tried to actually drive it across a parking lot, and it "ran out of gas" with plenty in the tank.

i drove the car and it ran a little better. got to about 6500 and then it just blows tons of black smoke out the exhaust. maybe i could just try to rev it and blow it all out?
sorry for the long wait

Lives on the Forum
First check your timing. If that's ok, then add a full can of seafoam to 1/8 tank of gas and drive the **** out of it....This will loosen up those stuck seals in just a few minutes, and if that's the issue, you will really feel the difference when they break free. This is my personal experience anyway...

I love this question! One answer is to put them someplace else (like cardomain.com) and provide a link. On the other hand, if you pay off the mods and get the secret codes, you can post humongous photos right here on the forum that take forever to download. I don't know how to do that yet. Here's my cardomain link:
