Question about smoking exhaust
 

Ok, I changed the oil again and put in 3/4th of a quart and its at the right level, and I rev it now and it doesnt bog down as bad if hardly at all, and then I started giving it gas to see if it still smoked and it only smokes after I let off the gas and it goes back to idling and it only smokes for about 2 seconds then stops, So basicly I give it gas it doesnt smoke, let off the gas and right when it returns to idling it starts to smoke a little bit. Any ideas whats wrong? Or is this normal?
