Need a bit of help. New plugs and wires today, fired right up. But, still back firing through carb. Pulled valve cover, found the issue. Cotter pin on front of rocker arm assembly was broken, the washer and spring were off and the rocker arm was wedged out of place. Front valve is stuck. Push rod was bent.
