Yes there is a drop in side loading as a result of the longer rod all the way down, I was saying in terms of cylinder fill / piston speeds, that once you are heading towards 90 degree the effect is very negligable
and correct the cylinder does begin to fill way before TDC, this is where along stroke crank would be better, but the short stroke will then aid on the power stroke by the speed the piston comes back down the bore.
Agreed what you gain on stroke length increasing or decreasing speeds where you want it, it will have the opposite effect where you dont.
I can't believe im having a techical discussion whist waiting for my child to be born !! pmsl.
Indeed, you could be out interviewing swedish aupairs instead!
