Hi Mops,
Can't help with any info on them but I had one of those for many years from the early seventies. In the early eighties I put the motor on a Pope base because it had a catcher on the side and I used that till the early nineties. Didn't have much compression left so I upgraded to a Honda powered Victa. Probably should have kept the old Hurricane would have still been going today with a new set of rings in it
