it is a start, you have to ( locally) shorten the piston, 1/2 way the inlet to make the left hand side of the inlet open first ( and close later) if the piston is still original in length remove about 2 mm ( in height) over a length of aprox 16 mm ( staring the measurement at the side of the slit in the piston, the ones you have made your own improvements on
