You did not mention where the spark plug is when you see this blue spark, If it's still in the head with the spark plug cap on the spark plug.. replace the cap/wire/coil - probably a one piece unit. ..now, If the spark plug is out of the head, and the blue spark is jumping from the porcelain tip electrode straight to the curved tip electrode - that is GREAT! THE SPARK MUST jump STRAIGHT across the electrodes... sometimes it's really hard to see if it's jumping around the side of the porcelain tower, then to the tip..this is a fouled condition and it won't run - even though its a bright blue spark!! Seen it too many times!!
