This mower is continuing to give trouble. I put another new plug in it New Years Eve because it hadn't stopped again but it was obviously running with the choke on. Choke was sticking on so I added a spring to help it to open. Then I couldn't get it started and the plug was dead. Put in a new plug and all good until today when he rang and said it wouldn't start again. I assume the plug has failed but I have no idea why. This will be the original Iridium that was in it and 2 of mine. Any thoughts?
