Does anyone know the exact opening and closing figures for the breather timing on a comet. I think my breather has slipped in the gear.

Refering to my ancient Instruction Sheet No6.
--Whilst the timing of the port is not very critical,it should close a few degrees after the crankpin has reached its lowest vertical position in the crankcase,,or about 30degrees past B.D.C of the rear cylinder.--
Obviously the factory still thought it only made twins,I wonder who made Comets:D John
