Hey guys so I'm new to the CB750 family but I recently inherited a '79 CB750k and only 2 cylinders were firing. I've timed the engine and all 4 are firing with the exception of #2 which is sputtering with an occasional backfire at idle. Carbs are clean but when I touch the throttle the engine dies and I'm at a loss. Any help would be appreciated!
