Andrew do not "guilde the Lily" looks like the hole thing was a fix, the only real problem I had with my paws was the 40 it would bog
with advance of the throttle from loading up at idle It was cured by going to a twin neddle MVVS carb, runs super I understand there
has been some improvments in the PAW carb at least on the larger ones since I do not have one, used one, or seen one cannot comment on it My latest is an 06 and its runs quite nicely even with the antique carb. As far as older Irvines tossing rods I have the old silver case 40 and 36 converted to diesel and they do fine the 36 swings the same props as the 40 diesel at the same speed. martin
