It never made it into production . It was said that Irvine were not happy with the carb . I think that as they distribute OS engines , it is more likely that they thought that the Irvine 53 would only take sales away from OS sales so it wasn't worth doing . Lets face it , the carb on the Irvine 36H worked fine , so they knew that they could make a good carb , or , as they imported OS , they could have fitted an OS carb .
If it had have come onto the market , I would have had one . I had even contemplated making a heatsink for the standard aero head , and giving it a go . However , as Irvine are now made by OS , they don't have a true ABC piston and liner , and I don't think that they are as good as the original Irvine built engines , so I doubt that I'll ever do it .
At the end of the day , it gets dark .
