Hi Robert.
Actually, if you read my post you will see that we are in full agreement.
We both state the source of the increased pressure as coming past the pistons, rather than the volume displaced by the pistons which is balanced out. And we both refer to the oil leak problem that ensues.
Interesting stuff about filling a 2-stroke crankcase. This was effectively the best way of increasing the compression ratios on a 2 stroke. I never went as far as you with using bondo, but I do remember there were a number of firms selling crank-case fillers which consisted of cast alloy pieces that slotted into the free space in the cranckase, giving a simillar effect. I know I fitted them to an Aerial Arrow that I owned at one time, around about 1967 I think.
