First thing I'd do is switch a plug AND wire from a cylinder that is working fine to the No. 3. Just because you see spark does not mean something is a miss there. I've had both bad/weak plugs and wires out of the box.
Also double check your wire routing for shorts. What was the culprit, the valve adjustment? Maybe bad lifter on no 3? Is the plug wet on no. 3? If not pour a little gas in there and see if it hits.
