One of the problems you may have already pictured is the difference in the style of engines like the .40 which I believe they changed several times. I fell in love the my ABC Foxes like the 40 delux, the 46 and I have a 74 abc. The newer .19 bb and the 25bb are great running engines too but need a little mothering to keep them happy.
