Stromberg diaphragm weight

[Gadgetman]

Does anyone know the weight of the Stromberg CD150 piston diaphragm weight on a Vitesse 1600 & 2 Ltr?

im trying to work out what I’ve got fitted and I’m told the 1600 pistons without piston  springs had different weight diaphragm retainer weights.

Cant get to a definitive  but just twidddled a mk1 and it had the heavy weighted and a  spring  

The 1600  def has no spring,  theat looks (without a pic of its thickness ) looks like a  std one as used on Mk2 

The  thick one is twice as thick 

Of a thin   one  is  fitted then add a spring  will richen up  the range 

Never use heavy  plus spring on the 1600  far too rich when running
