Yep all spot on. As for progressive, Im unsure as volume spoke success during this period. Unfortunately all the mower brands listed saw very limited success often selling very few but for Pace",and often less than generic store brands. The amount of mower brands probably made engine volume appear higher,but compared to Victa, Villiers and Rover to name a few,they fell far short and this is highlighted by their very limited availability today. A very good engine none the less and one of my favourites when fitted to hurricane Amplion and Pace and a brand id love to have more of, but they are just to hard to come by....
