Misfiring

Have you checked for ign spark at No 1 and 2 cylinder ign wires?
Remove the ign wires from all spark plugs. Have someone turn the ign to start while you listen the engine turn over (but not start). Listen for a uniform sound and pace when engine is turning over. NOT the engine RPM speeding up and slowing down. This do to lower compression on No 1 and No 2 cylinders.
