Did you get mis-firing while running? Mine is as sweet as until you turn it off.
I would change the HT leads but they are one sealed unit with the coil. I have cut back an inch where the plug cap screws into the lead and reconnected but as yet haven't run the engine to test if this might have made a difference.
