Wondering if a suitable replacement belt number has been identified? For a while I just used an old car v-belt on my Rover HD 25 that seemed to work okay. I eventually had to buy a new belt so settled on a slightly smaller A870/A33 belt. These are a very common belt and available just about everywhere. A tight fit, but seems to work as it should. I should add however that the motor has been replaced on mine with a larger Honda, which means the pulleys run a bit out of alignment. The belt seems to stay on there but probably wears out a bit faster. I haven't had any major dramas with it.
