Glad you got the genny going Max, I knew the Honda motor was good but back in the early nineties my son had said there was something wrong with one of the phases in the genny.
I was only thinking of the diff lock on the Greenie because using the single wheel drive makes turning so much easier.
As for the Rover no way would I repair one for sale, just a waste of time, just for starters I spent days rebuilding the deck, they are so simple and rugged and could go on for another 50 years as long as you can get new lining put on the friction disc when it needs it.
