OK, here's a cheap and dirty way to settle the 230/250 question.

Pull the plug on #1 and turn the crank by hand until the timing mark is on 0. Drop a pencil in the plug hole and mark it at the edge of the hole. Turn the crank exactly one half turn and mark the pencil again. The distance between the two marks is the stroke - not exactly, because of the angle, but it should be close enough.

Not to state the obvious, but make sure to use a pencil that's long enough so it doesn't get lost in the cylinder.
