smoking engine

Well,I got the car running,and I change the oil but it is still smoking black smoke,and the engine is shaking(not real bad).Could it be that the car needs to run for awhile,because I just changed the oil and filter today
And could someone tell me how the find out if the carburetor and fuel pump are bad?

Smoke n

Was it smoking before you changed the oil? Several reasons an engine will smoke. Bad rings. Bad valves. Too much oil. Bad valve guides.

Take the fuel line off the carb and put it in a bucket. Hold the end with your thumb. Have someone crank the engine. If the pressure moves you finger away, you have a good pump.

Black smoke is too much fuel, white smoke is water, blue smoke is oil.

Too much gas = fouled plugs = shaking motor.

Adjust your mixture, change the plugs (pay attention when you take them out, it your mixture was too rich, the plugs will be wet with gas) and fire her up again. Problem should be fixed. Has the car been sitting for awhile with old gas in the tank? You might want to change the fuel filter just on principle.

Could also be crossed plug wires alllowing misfire causing engine to shake causing it to run rich. Check the cap, rotor, wires, wiring sequence, and plugs. Also pop the hood after dark with no lights around and see if you can't see any plug wires arcing out.

how long had this car been sitting?

sounds like fouled plugs or crossed wires, did you mess with the spark plug wires? Bad gas will stink and make the engine miss. How old is the gas? To adjust the carb turn the adjuster screws in all the way, do not over tighten the adjustment screw, turn it in till it stops and turn it out 1 3/4turns to start. Using a vacuum gage attached to the intake manifold adj the screws till you get the highest vacuum then go to the other screw, on a 4brl carb, and do the same thing, you may want to repeat the process to get maximum vacuum. The black smoke is to much unburned gas the oil change should have nothing to do with this. What color are your plugs, probably black, right?? Change out those old plugs and watch you have the plug wiring correct. You know the firing order right?? Follow it on the cap of the distributor to the appropriate plug, one wire and one plug at a time, PLEASE!!

willing to try

Well,I am going to take the suggestions that were given to me about my smoking engine.The plugs are new,and the gas I put in when I bought the car about a month ago,The cap rotor and the module are also new.The only thing that I didn;t change is the fuel filter,and adjust the crab.I'll try those things and see what I come up with,and I'll let you know how things turn out.
The smoke is more white than it is black,But it isn't smoking very much any more,But it does keep smoking after I turn the car off.

Thanks for all of the help!!!!!!!!!!!!!!!

I'm assuming that this car has set a while without being ran. The common things that you'll find are stuck chokes, stuck floats in the carb and stuck piston rings. All can cause the missing and rough running. If the carb set several months or more with gas in it you might as well rebuild it no matter how well it's running. Sometimes stuck rings will free up by them self just from running it mildly. If not it's rebuild time. A compression test will let you know if you have a ring problem.
As for the white smoke check for water usage or combustion pressurizing the cooling system.

Thank you for all of the good suggestions,on how to get this car back on the road.I do take the suggestions that you guys give me,and so far you have been right.
I adjusted the mixture on the carb and it is running alot batter,I am taking my time doing,because I am not in any hurry to get it going(although I would love to drive it).
I also need to change the U Joints,and get some new shocks on the front.Then what should I do next?

What to do next? DRIVE IT!

Drive-drive-drive-it and drive it some more. Watch for leaks and watch the fluid levels and the engine temp and the oil pressure.

no the car has not been setting ,the lady that I bought the car from was driving the car.She just didn't take care of the car.
I am changing the fuel pump,and having the Carburetor rebuilt and changing the gas filter.But,no I do not drive the car,although I do start it and let it run every day.But,I can start driving it,so I can find out if it has any leaks and stuff.
Oh yeah,Thank you for the bit of information about the brake line I'll check it out
