Mine aren't quite in a comparable condition to yours. My first one (green) I acquired many moons ago. I cleaned the carby and after some dicking around (and quality father-son time) we had it running. Problem is, about the only way it runs is full throttle and rough at that. The second (orange) I found at the scrap metal bloke with no wheels but does turn over. I had acquired both before meeting you blokes and reading everything I can find on them. They are resting and waiting their turn.
I did pass up the chance to buy an excellent condition gold one with catcher at a swap meet a few years back. Been kicking myself since. Was only $100-$150 from memory. banghead
