A. more quantity of fuel is vaporized but not sent in cylinder during working of the cylinder
B. during acceleration intake manifold is supporting the working of carburetor as more and more fuel is sent to intake manifold instantly from the carburetor
C. because more fuel is consumed during acceleration and hence we send leaner mixture
D. fuel lags behind in intake manifold as vaporized fuel is passed in the cylinder and more fuel is collected in intake manifold which is not vaporized during subsequent strokes as during normal working conditions of engine
