Lambretta 150LiS Crankcase Leak down test

Carrying out a leak down test with a Blood pressure guage and 32mm bicycle inner tube to find a crankcase leak .
Leak found at crankcase throat to cylinder base joint, due to over-porting of the cylinder transfer ports leaving insufficient gasket face.
Solution was to fit a rigid 1.5mm Aluminium base gasket together with Threebond liquid gasket
