Hey guys back onto the mower this evening and the forum, great to see and much appreciated all the responses very helpful. Now of course the mower is not starting, troubleshooting down to no spark (new plug installed) which is why i suspect the ignition coil but before i replace it i want to check the wiring. There is one loose wire i am not sure about which is circled in red on my photo, could someone please confirm where this should be connected to? Also i am guessing the top of the mower need to be taken off to get the remaining wiring for the replacement of the coil? The nut is seized on at the moment but will keep working on it. Just to check it is left or right handed thread? Thanks!
