Your timing is probably retarded by a few degrees whether it be the distrubutor physically, the mechanical advance (springs too heavy, weights too light or the weights not moving freely), a stretched timing chain or possibly the timing chain has jumped a tooth. There is also a possibly its as simple as the carburetors accelerator pump or linkage is to blame
