The problem with .60/.61 2-strokes is that they're really inferior from a power-to-weight perspective.

Most of them only have a little more power than a good .46-55 (in a 40-wised crankcase) but weigh quiet a bit more.

What's more, these days most .60-sized engines are also available in .90/.91 displacement which brings the power-to-weight ratio back to .46-.55 levels.

Maybe for a warbird?
